'[BUY]: PICMASTER T-Probe'
2000\11\03@104826 by Mark A. Samuels

flavicon
face
Does anyone on the list have a Picmaster T-Probe (16C66/67/76/77), either working or not working they'd be willing to sell?

Also, I acquired two ICE-PIC daughter boards (16C62X and 16C64), but I don't have an ICE-PIC!  Let me know if anyone is interested.

Thanks,
Mark

Mark:

I've got one, but it's for the PIC-Master CE; it won't work with the
regular PIC-Master without an adapter.  The adapter used to be
available from Microchip; I have no idea if they still sell them.

If you can use the CE probe, let me know; I don't think I want to
sell it at this point, but I'd be happy to lend it to you for a while
if you pay shipping/insurance both ways.

By definition, a webcam with digital interface (parallel, USB, etc) is
neither NTSC or PAL.  Or looking at it another way, your computer becomes
part of the "camera", and can output whatever it wants given an appropriate
video card...

Client's managed to confuse me, I guess - I'll look into it more.  They
definitely want more scan lines than NTSC provides - And want PAL video
output with those extra scan lines.  They keep stalling giving me specs
on what they want (A PAL "Ball camera" or lipstick camera may be what
they want, they're sorta arm-waving over the phone at this point <G>)

>PAL webcam ?

Hi Mark,

you need to make the client state whether he wants a PAL format TV signal
or a digital stream of images that is roughly equivalent to PAL TV  (i.e.
50 fps and about 800x600 pixels at 10 bits resolution). Then try to
understand what digital format he wants ...

... therein lies the problem;  I'm starting to think he wants a PAL

Hi everyone,

I was wondering if anyone knows about a single chip recorder and playback.
I looked in a lot of places to find the chip number and I only found
ISD1410.  However, I cant find a distributor for this chip. Please let me
know if their is any other recorders and playback chips or if their is a
distributor for the chip that I am looking for.  This chip is ultimately
going to be hooked up to the PIC.
Thanx for your help

Digikey has a whole series of ISD chips - ISD14xx/25xx/etc.
Jameco also carries some.

Go to ISD's web page, they have a lot of different variations of the ISD
chips.

http://www.isd.com/products/chipcorder/

There is also a link on that page to find out what distributors are in your

Something like a 74HC4052 will give you a garden variety

This part is used to drive a single LED digit, and three make a three digit
counter.  I designed a new product for the customer, and this one is a pre-me
unit that they want repaired somehow.  The 5V regulator gave up and the oh so
delicate logic was exposed to 20V indefinitely.

OK, I'm fairly certain I won't have any of those.  I was very partial to
TIL311 LED displays when I had to use LEDs -- builtin decoder/driver, feed
it 4 bits and get a hex digit. I was lucky enough to pick up a couple of
tubes for free...  simple to use, but those were pricey little critters!!

Why not emulate the part with a PIC ?

I too am looking for something similar.

I only need a 2:1 mux, but I need it to be suitable for switching NTSC
video signals quickly (ie 29.94 Hz, or whatever it is).  I need it to
switch between two sources between each frame, and it has to be "clean"
enough to not muck up the sync signal.

Any ideas?

p.s.  Switching at Frame Rate is not (in video terms) switching
"quickly" in fact this is the slowest switching rate.

Switching at frame rate is a heck of a lot quicker than my Sony home
theatre receiver will let me do.


I said "quickly" to impress that I didn't mean that I would be
switching once every few minutes or so - and that I need to maintain a
clean sync signal, etc.  (ie a relay ainn't gonna cut it)

Steve, in the TV industry is it common to use the cheap
4066 quad analog switch chip for AV switching. I buy them
by the bagful. They will switch at frame rate with no probs,
and will switch the standard "AV inputs/outputs" that come
from the back of your set. And they will commonly fail
with weird faults after 6+ years in a hot environment.
Especially the Toshiba brand chips. :o)

I have used maxim analog switches for this in the past. obtaining stock from them was at times a bit
scary as they were having some fab problems which they were not being too candid about.
'Standard' 4000 series analog muxers should do this job just fine (check the bandwidth specs to be
sure as I have only used them for audio, but I seem to remember they had plenty of bandwidth to
spare).
You will get better results if you buffer the video into and out of the muxers (iirc you can get
parts from Maxim with built in buffers).
Remember you ideally want to time your switching point to be in the vertical blanking interval so's
you don't get a visible switching point, this also means having locked video sources... if this is
for a home system then you won't be able to do this so you need not worry about trying, just means
you'll get a splat & probably some roll as you switch the signals.

Regards,
Simon

2001\02\08@112255 by Intellicorp001

Hi,

  My name is Wilson Logan. A few years ago I got a friend to help me build
a data logger based on the PIC 16C74A-04P. Unfortunately, in the final
throws of the project, through no fault of his own he was unable to complete
the thing.

  I've thought about finishing it myself but although I could write the
assembler, the electronics would defeat me.

  I've got 1) A circuit diagram 2) A board design 3) A parts list 4) The
assembler for the microcontroller 5) A delphi program to receive the data
from the logger 6) A prototype (minus the PIC Chip itself).

  As I understand it. The thing is up & running minus some work to get a
real time clock going with it.

  I'm a private individual with limited means but I've got a couple of
hundred pounds worth of a budget to get this finished.

  If anyones interested they can contact me via email at

  @spam@intellicorp001@spam@spamspam_OUTmch10.sbs.de


  I don't mind where in the world you are (I'm in Munich).

       Best Wishes,

              Wilson Logan.

Anyone know of a source for the reprogrammable USB-compatible

probably cuz I don't know where to look.  Arrow, Digikey,
Pioneer-Standard and Future  don't have 'em.

An additional problem is that I'm just a hobbyist and don't
represent quantity future sales, so getting engineering samples
probably isn't going to be easy for me.

I'd appreciate any help y'all could give, and if you have one of
these in your junk box that you don't need, I'd be happy to take
it off your hands.  :)

Thanks,

I got hold of 6 x 745/JW and 6 x 745-I/SP just after Christmas I had
been waiting for also a year for them and finally managed to place an
order in mid November for them with a UK supplier.

I did have 1 engineering sample in September which was a 745-I/JW ES
00250A5 the 6 I got a few weeks ago were 745-/JW 00430B7

You should be able to purchase Maxim Parts directly from Maxim.

Hobbyists probably don't use Maxim parts - they're just too durn
expensive - I always wonder who can afford to buy their stuff.

D-K seems to be the major hobbyist supplier of Maxim parts, but there
must be other guys - maybe Allied, Arrow, Future.

From what I can see on the ARROW web site http://www.arrow.com this particular IC
is reserve for large manufacturers. Arrow a fairly but there is quite a
variety of prices.

I chose Arrow as they are well represented around the world. I purchaced the
MAX1676 DC-DC converter Eval Kit from them and found it cheaper than buying
direct from Maxim. I also found that I can buy small quantities for research
and have good prices for quantities

Arrow seem to distribute many components.

I've missed the start of this thread but anyway -

It'll probably be cheaper to convert the equipment to 25 pin - you have to
file the openings out 2.5 mm wider and
pull the pins (carefully) out of the old sockets to fit into the new ones.
Hint - a temperature controlled soldering iron can be set for a temperature
that, when applied to each pin, won't melt solder, but will soften the
plastic around the pin enough for it to be removed without damage.  Pins
removed this way can then be cold forced into another socket.

Practice on an old piece of equipment to convince yourself that a new 25 pin
socket plus 10 minutes labour is a viable alternative to sourcing (and
paying for) rare 23 pin plugs.

Bye.

Compatabilty is the key issue - already 300 systems in the field.

They shouldn't be too expensive - maybe AU$10 per plug/socket/cover set.

I have a 1996 Videk UK catalogue that lists D23 covers - might be

don;t know if this is still current, or the company is still there? Their order codes 7303G/B/M (Grey/Black/Metallised)

Toby Electronics (UK) (+44)1295 271777 fax (+44)1295 271744, who are
definitely  still around, list a 23 way shell :

Part number 11D-C-23-n-m
n is 2 for grey, 5 for metallised
m is 1 for short screws, 2 for long

Toby can probably also supply the connectors, but there may be a MOQ

CPC still list the connectors, probably cheaper then Farnell

From my experience, literally "any" parallel-cut xtal will work
with a PIC. Never seen nary a problem [although others have]. I

Sven, if worst comes to worst, and you still must fix this equipment,
you may be able to get by with cutting out the chips and soldering on
some discrete NPN inverter circuits. That is really all RTL was.
Somewhere I have an old textbook showing nominal resistor values.

Milton;

I have been working on some modernization efforts for the nuclear industry.  They have a number of designs which used this old logic.  The logic, if I
recognize the numbers, are MHTL logic, which is a high threshold logic version of DTL logic made by Motorola.  I would be wary of Dan's suggestion for
replacing with transistor logic, Dan assumed RTL, and in reality they are a bit more than that.  He meant well.  The best bet is to use a comparator around
7.5V (this is fixed regardless of supply) and then deal with the logic levels.  Outputs are either an active transistor output in a peculiar buffer
arrangement, or a passive pullup with active pulldown.   Not a clip out solder in solution.  I know that the nuclear industry went absolutely to the end of
the earth to find these parts, which have been out of production for probably 25 years.

Wish the news was better.  Sorry.

If you want enough $$$+ worth to make it worthwhile for them, just contact
a gray

According to the textbooks [if one can believe them], "all" of the
old RTL, DTL, and HTL gates are fairly straightforward NPN circuits.

So, if unable to find these gates/chips anywhere, and if fixing
the equipment as opposed to trashing it is the major consideration,
then it would seem that clip out solder in may be the only possible
course of action. It cannot be all that difficult to try, assuming
only one or a few gates are blown - either works or doesn't work.

Unsolder the old chips, solder wirewrap headers into the holes, build
a new gate on fiber board [kind with plated-thru holes], and solder to
the WW legs.

[of course, this thing probably wouldn't meet FDA approval].

No, this is what "has been" running our nuclear plants.

Hi Dan,

No.  Original poster was asking for replacements for RTL
to repair X-ray machines.

Second poster said to swap discrete transistors for RTL.

Third poster said he'd been working with the nuclear industry
on RTL and other old logic families and warned _against_ using
discretes as replacement parts.  He said the nuclear industry
has bought up all the old replacement parts to keep their own
equipment running with the proper replacements.

                                               Lee Jones

P.S. Last I heard, air traffic control system was still
    on IBM 9020s, circa IBM 360 level of technology.

Thanks, yes they do. I generally found in the past that Farnell
were pretty much on a par with RS so didn't look (my last
catalogue got biffed out some time ago). The price they
gave me was Aus$21.04, which by the time you add sales
tax, freight and conversion comes to NZ$30.43 each. Ugh.
To go without them though will mean a lot of extra coding,
more than $30 worth for sure (just trying to cheer meself up).

Hi, We've gotten backed up with projects, and there are a few
personal ones that have been sitting in file folders for months.

Anyone interested in a SMALL amount of money for taking these
from schematic to Orcad PCB MAX files (including creating
footprints)? Timing is flexible, all are "speculative"
projects.

Most of my stuff is mixed signal 1-4 layers sometimes with
high voltage/current. Typically 30-150 components with
10 requiring special locations, in board sets of 1-3 boards
per design.

There might also be some PC Win32 programming (to interface with
PICs etc.) and some ethernet-TCP/IP micro-based programming.

If you are interested, pls. let me know your rates and what
similar work you've done as well as availability.

Hadn't heard of them before. Rang a NZ number (Christchurch)
and waiting for a call back. If they're part of the same organisation
you used in Aus I may be in luck. F628 not stocked yet by RS or
Farnell, Avnet dumped by Microchip, thought Arrow were the sole
agents

I purchased one from Farnell about a months ago. I had to wait
3 weeks to get it. Perhaps they got more than 1 in!!
The description on their web site is confused. I hope they have
fixed by now. I had to have a little talk with them.
Zatek (Pic distributor in Australia) were kind
enough to give me a sample so that I could finish off a project.

Oh. I rang Farnell (Aus) on Friday and they said it was not one
of their products yet. Same with RS. I'm trying like heck to avoid
their kind of price. 1 I might buy, but 6+ is just too hard on the

The following is right out of their web site order confirmation,
except that the description is incorrect and the part number is
infact for the 18 pin plastic DIP which is what I wanted.
The price is of course 3 times what one should pay.

(Farnell Part 2)    3154786
(Description 2) IC-SM-8-BIT MCU
(Quantity 2)      1
(Price 2)    $    15.9400$

Ah, that sort of clears it up. Future Electronics think they can get
a tube @ US$3 each (US$100 min order so probably 2 tubes),
but like Arrow they're out of stock too (4 week lead time). The
freight on that deal would be US$29, ouch. US$179 (2 x 25 x 3
+ 29 = NZ$436) far exceeds what I want to spend just to get the
1/2 dozen I need for now. I've had an off-list offer at a much better
price and quantity

Ethan,

There are many bargains on this sort of equipment on eBay.

You can probably get a good start on this for around $500.00.

For example: Tek 465 scopes can be had for about $200.00 (make sure you buy
one that comes with probes. A pair of new probes will cost you at least
$60).

Hi, Harry... there must be a shortage of these things...
my gray market dealer says $32.50 (!!!!!) min 100, 5 days.

Maybe try one of your local version of these fellows. 8-(

Hello
My company is looking for 6' power cables with a regulated 12V wall wart 600-800 mA -- the connection doesn't matter as we're going to snip it.  We need a couple hundred. I am having a surprisingly difficult time finding a supplier -- the density of products which ship with said connector makes search engines all but useless.  
Can anyone recommend a distributor or manufacturer?

Barnaby,

Check with Radio Shack.  They have a 12V/1000Ma Power Adaptor.  I
can't remember the cost for sure now, but I believe it's around
$15.00USD or so.  RS part number 273-1776.  It has a connector on
it that is a two pin side by side affair that is meant to receive a
target device specific connector.  But if you will be cutting off
the connector anyway, it doesn't matter.   Hope this helps you out.

                                           Regards,

                                             Jim

'[BUY]: Looking for PIC 16/18 firmware developer'
2001\05\22@185025 by ron

flavicon
face
Hi fellow PICLISTERS -- I'm looking for an experienced firmware
developer familiar with PIC C to help us out.

My name is Ron Wilder and I've been on the list for many months now as
"Wilder Engineering" and have really enjoyed reading the messages "in
the background".  While doing so, I have started a small, new company
that is developing an exciting set of products and services which is
based significantly around PICs.

A little history
Our company,  Agile Access Control, Inc. is searching for someone who
might be interested in doing some custom firmware for our company.  We
are developing a product that melds web and touch-tone telephone
scheduling with hardware to control the check-out and return of physical
keys. My previous company (http://www.wilderengineering.com/ed) develops
touch-tone and computer-based reservation systems for flying clubs,
car-sharing groups and even the FAA (at the Air Traffic Control Command
Center --- you should see this place!) and it just seemed like a natural
progression to develop a product to hand out the keys that were
reserved.

Soooo... I convinced the program manager that I worked with at the FAA
command center to quit his job (this was tough, considering that he got
to see and play with all of the neat toys at the FAA), be the company
CEO and work with me to develop this product. Since then, we've been
putting a team of people in place (all from their homes at the present
time) who specialize in areas including web developer, firmware
engineer, sales, marketing, accounting, mechanical engineering, and, of
course, myself as CTO (Chief Technical Officer) and jack of all trades
(hardware, firmware design, touch-tone software design, etc.). We
formally incorporated in California last September and we have already
demonstrated our initial prototype system at a trade show in San
Francisco a couple of months ago.  The customers are already lining up.
We have interest from the commercial sector, universities, state
government, and a large military
customer.  Now all we have to do is deliver the product!  Heard this one
before????  Me too!

As is predictable, the firmware has taken much longer than anticipated,
primarily due to our firmware engineer's requirement that he only work
on weekends...  Anyway... we now realize that we need to find someone
who can commit to reasonable schedules and will do whatever it takes to
make commitments that are made.  We will reward this individual with
stock and $$$.  We also have a bonus plan based on sales as a teaser.

Interested???  Additional details follow.

Agile Access Control
Incorporated Sept. 18th 2000.  Privately funded C Corporation based in
Campbell, CA. (Silicon Valley).  We do have about 10 people at the
present time working throughout the country from their homes.  We have
customers waiting for us to release our first product and they are very
excited about how it will really help them revolutionize their business.
Check out our web site at: http://www.agileaccesscontrol.com.

Hardware
We have a neat product and uses a lot of PIC controllers that talk via
the i2c bus.  Our product includes neat hardware including:  proximity
card/fob reader, credit card reader, RF transceiver (short range), LCD,
tiny modem, keyboard, serial I/O, motors, iButtons, embedded web server,
thermal printer... to name a few.


What we need
Ideally, we would like to find an experienced, self-starter who can help
and perhaps lead the firmware effort on a more dedicated basis.  You
would need to bring PIC C experience with you as our schedules wouldn't
allow us to train you.  You would also need to have a track record
developing embedded systems (and have a verifiable resume that supports
this) and have experience writing code for specialized hardware such as
that mentioned above.  I'm not expecting that anyone have experience
with all of the above hardware, just enough of it to convince me that
you have the required experience that would allow you to easily develop
code to get it up and running.

We are on a "fast track" (surprise, surprise) but at the present time
and for the foreseeable future, we all get to work at home and own a
piece of the company.  You'd be working directly with me and possibly
another firmware engineer who has developed our demonstration firmware,
to date.

Myself (You'll be working directly with me)
I'm a degreed (U.C. Berkeley) and licensed (in California) Electrical
Engineer with a strong hobbyist background. I've been an amateur radio
operator (K6RON) for thirty years (although fairly inactive lately) and
have designed both hardware, firmware and software for over 25 years.
I'm a private pilot, SCUBA diver and nerd to some (you should see my
computer room).  I'm also a MicroChip Consultant.

I've enjoyed designing the hardware and some of the test firmware, but
it has come time to try to find another person to help in the firmware
end of things.

Your Location
Ideally, you are located in either Northern California or near Chantilly
Virginia.  This would allow easier face-to-face meetings with us. Of
course, joy rides in my 4-seater Mooney airplane will be more frequent
the closer you are to San Jose!

Still Interested???
Let's talk!

Please send email directly to me at:

I+need+someon

Hi there,

We found your site by a quick search.

We are a small distributor (come manufacturer) of CCTV equipment.

We are searching for a company or an individual to do some pic programming
for us at a reasonable cost. Are you interested?

Overview.
We require a pic that is fairly small in size and reasonably low cost. The
pic will do nothing special and is basically a timer with 3 outputs and 1
trigger input. One timing period needs to be adjustable using simple
external components such as a variable resistor.
Operating voltage = 5V.

We need the following to happen;

1 -A pic to start a timing routine on a negative input.
2- A pic output pin, say "A" to go low for 1 second after the input.
3- Start a timer (0-5mins) that inhibits another input causing "A" to go low
again during this timed period.
4- At the end of the timed period cause a second pin to go low (say pin "B")
again for 1 second.
5- Whilst ever the timed period is running a third pin "C" goes hi-low at a
rate of about 2hz.
6- After the timed period the input now accepts a negative trigger to start
the routine again.

Notes -
The timed period needs to be adjusted by a small variable resistor or
similar from say 0-5 minutes. None of the timing is absolutely critical but
+/- 10% would be great.


What do you think?

Can you please let us know as we are keen to find someone to help us out
with this project. If you have any ideas about costs, please indicate these
as it will be useful.

Many thanks,

Paul Goodwin.

Wow, a blast from the past! I was the guy that did the factory code on that
chip for the Intellivision. Could you tell me what you are going to use it
for?

You know that it was an IC copy of the DEC PDP-11 with a few addressing
modes left out and the 16 bit ALU simulated by folding the registers and
doing two operations. I presume that you also know that it was the chip to
which the PIC was the "Peripheral Controller".

My guess at a source would be an old Intellivision or two, but I presume
that you already knew that.

Go to any of the manufacturers that make switching regulators (such as
http://www.linear-tech.com/ )  The app notes and data sheets will have
tons of designs, and many have programs for making custom circuits with
a few inputs.  National has a web based switcher design program which,
while limited, is very nice.

'[BUY]: Soliciting for input regarding Solder Rewo'
2001\07\19@162830 by James Paul
flavicon
face
All,

My employer has decided that we need a Hot Air Solder Rework
Station.   So I am asking the PICLIST for their inputs into which
mfg or vendor has suitable units from which to choose.

I myself have had some experience with HAKKO.  Another guy here has
experience with PACE.  And we have both PACE and HAKKO equipment in
the lab.

So, the questions are ....

1.  Which manufacutrer do each of you prefer? ..and..

2.  Which unit from that manufacturer do you each prefer? ..and..

3.  What other manufacturers are there out there other than the
    two I have mentioned? ..and last but not least..

4.  What is the price range?

It should be capable of handling components down to at least 0402,
and preferably smaller.  It also should have some sort of XYZ type
adjustment (Such as a micromanipulator) for precise component
placement.  A means for dispensing solder paste and a preheater
would also be beneficial.

At this point in time cost is not an issue.  But the unit will be
used mostly in our engineering lab and not in a production
environment.  So production capacity is not necessarily needed.

Anyway, I'd appreciate hearing your thoughts and suggestions.

Email me offline if you wish to save list BW.

'[BUY]: Motorola Cellular Connection - ( modem for '

Any list users interested in a Cellular Connection for Motorola Bag Phones ?
I have one which is no use to me as we no longer have an anlogue mobile
phone system in Australia. I have previously used this device for remote
monitoring of data loggers and know that it worked.

I can not verify that it is identical to the units used in the US except
that the model number is Model S1936C. You may be able to check with
Motorola to verify.

When I used these devices, in this country they were more expensive than the
phone itself.

I only have one unit, so anyone interested can make me an offer.

If you need only one have you considered "hacking" together one? For
example, a 120V-24V step down transformer (very standard) hooked up in
reverse yeilds about 600V output, for 2.5A output simply look for a 24V
transformer that outputs ~12.5A at 24V. You do have to be a little careful
about the insulation but I'm sure you would be able to find one much easier
then a 120V-650V step up transformer. TTYL

If you need a custom transformer there are some toroid transformer
companies that have reasonable prices for single units.  As a bonus the
result will likely be smaller, lighter, and quieter that a standard EI
core unit.

I disagree on almost all points here. First, transformers are carefully
made to work OK at the given frequency and voltage. Putting 120V 60Hz into
a winding meant for 24V 60Hz will saturate the core so badly you'll think
a mule kicked you. Also, 650V 2.5 A is 1650 Watts. 24V 12.5A is under 300
Watts.

While you could probably put 120V 400Hz into that 24V 60Hz winding, you
will need a transformer rated for 1650 Watts. At 24 volts, that is almost
60 amps, although you will only be putting 12.5 A into it.

Using a transformer at other than rated voltage is not likely to be
efficient, and something that big needs to be.

Cheerful regards,

Bob Blick

P.S.

I notice that although the PICLIST-to-USENET interface obscures the email
address in the header, it does not do it in the body of the email, so if
your message is quoted by someone else your email address passes through
and is harvested by spammers. Whenever I post to the PICLIST, I get spam
within a week. Whoever is doing the PICLIST-to-USENET gateway, I wish you
would STOP! How many people actually read the PICLIST from USENET
anyway???

No!! 120V into a 24V winding will probably give you less than 200V out, and
will definitely give you SMOKE.

You can go lower than rated voltage, but not higher.

Do you really need AC out? I would suggest getting a suitable isolation
transformer, say 3KVA, like you would use for power tools, and then have a
voltage multiplier rectifier arrangement on the output.

I've never liked the idea of overrating a transformer
like that.  Although it can be done, if I'm going to
spend a few hundred dollars on this device, I want to
do it right.  If at all possible I don't want to have
to modify any transformers either, or have to use any
type of multipliers.  I'm hoping someone on here can
lead me to a source of transformers for what I am
looking for.

But thanks for your reply, I appreciate you trying.

Another option may be to check people who do advertising signs for
transformers that drive neon signs. I do not know what the voltages involved
actually are, but it may be worth a try.

Another loop may be to try ballast units for mercury vapour lamps. Again I
do not know what the strike/sustain voltages are, but may be in the
ballcourt for what you want.

Check out McMaster Carr.  I believe I purchased a 220 to 600 Vac step up
transformer from them at a different job.  I used a 110 to 220 step up to
drive it, and sized out all the KVA's.  Worked ok, since it was designed to
do this.  I don't think I spent more than $100 on the transformers.

just a spurious thought

Two identical microwave oven transformers

Series connect the primaries (to halve the secondary voltage)
Parallel connect the secondaries (to double the output current)

OK so it's a stupid idea, and probably of no relevance but if
you extract them from scrap units you couldn't get much cheaper

550VAC transformers (often called "600VAC") are easy to get and cheap in
Canada, and similarly 480VAC transformers in the USofA (one of the few
differences in the electrical systems). This is a good idea. You'd go to
the "Electrical" transformers rather than the "Electronic" types (open,
dry 'control' transformers).

If a 480VAC transformer secondary is put in series with the incoming 240VAC
(no isolation!!!) or an isolation transformer then you get 720VAC.
120+480 = 600VAC, 550VAC + 120 = 670 VAC etc. Hammond should have both
types.

Well it is electrically sound.  The transformers don't even have to be a
matched pair.  What are the specs of a typical microwave oven
transformer?

About a kW or more normally. An oven rated
for 800w power will have a transformer that
runs reasonably cool.

I just sold about a hundred of them for
scrap metal, got about $1 US per kg. You
collect a lot of junk when you fix a few
microwaves a week for years. :o)

Another suggestion would be to pull one
apart, unwind some of the secondary winding
until you get the right output voltage,
assuming of course you de-rate total
power accordingly. Just don't change the
primary turns. Many are dipped in goop
so you might need to soak in something
first.

More specifically what the transformer will be used
for is charging a 36uF 950V capacitor.  This capacitor
is part of the capacitor inductor pulse forming
network that drives the flashlamp.

It turns out the pulse rate for this laser (SSY-1 from
Meredith Instruments, http://www.mi-lasers.com) can
only handle about a 1pps repetition rate, for some
reason I thought it could handle a higher one, but at
1pps I won't need as large of a transformer as I
originally thought.

Also, it seems like the only transformers I can find
that come close to what I want are around 625 volts,
or 700 some volts.  I want something that will be able
to charge the capacitor up to 900 volts, but not go
over the capacitor's voltage rating of I don't
continuously fire the laser.

If I can't find a transformer at this voltage, I may
decide to use a multiplier to double one with half the
voltage, but I don't want any x3/x4 or cascade type
multipliers.

And thanks to everyone for your replies up to this
point!

> 950V 36uF *DC*

Oh, when you rectify a voltage you get 1.41 times Vef. If you rectify by
doubling, you get 2.82 times Vef. 950/2.82 is only 336Vef. You have only
~17 Joules in the cap, once per second is 16W. Assuming poor efficiency
etc it is still less than 50W. A small comfy DC/DC converter will power
your application easily. No iron is required. Are you sure about the cap
specs ?

In which case a diode-capacitor voltage multiplier from the mains

650V * 1.414 = 919V

This is awful close to the 950V rating of the cap. It is generally not
considered good engineering practice to run high voltage electorlytics very
close to their max rating.

Personally I would build a flyback type switching supply with a voltage
clamp.  Flyback supplies operate as a current source capable of very
high voltages and they don't mind being shorted.  You can synthesize a
high voltage zener to do the clamping using a real zener, a few
transistors and resistors.

For a laser supply I doubt it is an electrolytic.  It is probably an oil

It seems to be some type of metal film capacitor, but
I do know for a fact that it is not electrolytic, as
the pulse discharge must be very fast (I think it is

'[BUY]: Vacuum fluorescent displays'

Hi,

I am looking for a VFD display, preferably somewhere in Finland :) Something
along the lines of 20x4 characters, i.e. pretty similar to the cheap LCD
displays they sell everywhere, except I would like VFD :)

Matrix-Orbital(.com) sells them with some add-on stuff to allow you to
program it serially (they also add keyboard adapters? why?) but they're
priced a little hight ($137) which would defeat the purpose of the otherwise
low-cost project. Also, I don't need the serial interface or any of the other
extra's, just a nice VFD display :)

AFAIK Bebek and RadioDuo (both in Finland) don't have any, or at least not
advertised, anyone know where I might have more luck?

Kind regards, and thanks in advance
Dennis Noordsij

While my knowledge of electronics sources in Finland is next to nil, don't
expect to get such VFD displays for anything like the price of an LCD display.
They cost 10-20 times as much, and are quite power hungry. Try surplus
sources, you might get lucky. They're used a lot in pay phones in North Am.

Still expensive but I have seen more like 2-4 times as much from what i have
seen by poking around.

Not in Finland (sorry) but it is a source:

>and are quite power hungry.

When comparing with many similar sized LCD's backlights being on, the
Noritake VFD's take less power.  I don't know about Futaba but I would
assume that they would be competitive.

I am interested in how to get those VFD's as well.

So i checked your link/search and it has expired at

No futuba or Noritakes.

So if any one else knows a source ........

Well, Digikey charges about 5 * as much for LCD displays as some sources,
so I think we agree. ;-)  I have yet to find a 2 x 16 display for a cheap
price (like $10 or $20 in 100's), I'd love to though.

Just to point out something about C2C, for those who don't know: you can't
buy it anymore. You can buy the Optama compiler from Kanda, the result of
Kanda buying C2C from Pavel Baranov. But you can no longer purchase a
registered copy of C2C.

And yes, there is a bit of a difference in price: C2C was under $50USD,
IIRC. I think Optama is $200USD.

Sorry if people already know this - I've just been noticing a lot of
discussion about C2C recently, and though people who don't know, might like
to know that it, like the parrot, is pinin' for the fjords. Might save some
confusion when the trial period is up, and there's nowhere to send the
cheque.

Prices somewhat high, but incredible range of components and excellent

The printed catalog is a "must have", however their on-line catalog is not
quite so good.

Aparently the catalog and range varies somewhat from country to country...

Similarly with rshttp://www.com who are a major competitor to Farnell, and
produce a similar multi-volume catalogue. Their CD catalogue is a lot better
than Farnell's though from the usability point of view. Many companies in
the UK use these two companies as their "Just in Time" parts suppliers
because of their overnight delivery times. You may find that there are South
African branches of both, else try going through their Australian branches.

Both companies supply a wide range of items from electronic components
(including a wide range of surface mount) through test equipment and books,
mechanical parts (plastic boxes, metal chassis, extruded aluminium brackets,
wide range of heatsinks, screws, nuts etc) to health and safety items
(ladders, hard hats, safety labels, yellow/black stripe tape etc).

It pays to check the Farnell prices. I bought my scope through
them because they were cheaper than the local Tektronix disti by a
few hundred dollars. They are also competitive on some of the PICs
for around the 100 qty.

The two international suppliers that I use the most are Digikey for
qty < reel and Future (although MOQs apply). Digikey has a good
website for ordering and they have improved the international
ordering a bit. Watch the freight costs though.

Future have local guy here, but like most of the suppliers, they are
a) generally hopeless and b) small business unfriendly. However, I
deal directly with an account manager in Canada and get really
good service. I think he's spent more money on "how's it going"
phone calls than I've spent on components. YMMV.

       I am reminded of an old Idea For Design or something like that it one of
the magazines. It was "How to use a Z80 to compute square roots." The
circuit consisted of an op-amp with a Z-80 in the feedback loop. It used
the Z80 as a diode to get a logrythmic I/V curve to compute the square
roots!

It is actually a timex/sinclair 1000, but that is practically the same as
the original ZX81. I loved it too. I modified it to output video instead of
UHF TV signal. Worked fine some time, but at one time it simply did not work
anymore. I guess the video output pin of the big ASIC has lost its white
smoke. It weights 350 (PCB + kbd, no 16k RAM or wall-wart). I must have an
azmic EPROM (assembler 'IDE') somewhere.

I guess an emulator on a PC is an easier way for you to play with your old
tapes...

that it only had 4 chips in it, and they controlled everything including

Hello,

I'm looking at getting an oscilloscope for myself, but I don't want to
spend a ton.  Plus, I won't be using it that much.  I'd file it under
the "nice to have" category.  I doubt I will be doing any high speed
circuits or anything.  I'll probably use it mostly on digital logical
and computer peripheral interfaces (PS/2, etc.).  Could anyone
recommend a good beginners scope around the $300-$500 range?  I don't
mind looking at used stuff on eBay, but I don't know enough to not get
screwed.

Bitscope looked interesting, too.  Has anyone had experiences with it?

I have a ton of old Tektronix stuff that I was thinking of selling on Ebay.
Most is the 7000 series, though I do have some 5000 and 500 series.  The
500 series is pretty much for collectors... old tube equipment (If anyone
needs any 500 series plugins, give a shout)

The 7000 series is nice, it uses modular plugins to accomplish many
different functions.  I have vertical amps, horizontal amps, and multimeter
plugins.  I could set you up with a complete scope that also has a DMM
readout on the screen (only catch is that the DMM doesn't do AC
measurements... but then you have a scope!!!).

If you are interested I have the following mainframes:

7704A  200Mhz, 4 bays, analog, excellent condition
7834     400Mhz, 4 bays, analog storage, excellent condition, storage
functions OK
7603      100Mhz, 3 bays, analog, good condition


I also have multitudes of dual channel vertical amps (including
differential / comparator). I have one logic analyzer plugin with all
cables.

A good assessment of fair value is http://www.vaxxine.com/phil/scopes/scope
$.htm

You can find more info on the 7000 series at
http://www.tek.com/Measurement/cgi-bin/framed.pl?Document=/Measurement/Support/faq/history.html&FrameSet=oscilloscopes

and

http://www.caip.rutgers.edu/~kahrs/testeq/7000.html

Prices on Ebay have looked pretty good recently, I guess it is a reflection
of the economy : (

I bought a Tek475 on ebay for around $200. I don't do much with, it's just nice
to have, but it does everything I need. Granted, its not a fancy digital scope,
but its good for simple stuff. Kinda wish I had a manual for it though.

I've used my Bitscope for looking at one-shot events. Quite handy.
There is some new front end software out for it since I bought mine.
An analog 'scope is still what I use most of the time though.

Hi,

> Bitscope looked interesting, too.  Has anyone had experiences with it?

   I have one and it is a nice equipament. Very limited by the software
available for it but has worked for me many times. There is nothing like a
good analog scope for first analysis. With most of the cheap digital scopes
you have to know what you are looking for to be able to see it. If you have
to choose between a digital or analog scope get a good analog one first. At
least that is my opnion. You need both But my a.. has been saved many more
times by the analog one than by the digital scope.

Alexandre Guimaraes

If you don't need DC you can use an op amp as a feed to a PC sound card with
the correct levels - there are lots of virtual oscilloscope programs
available and most hobby electronics companies have a cheap design available
for home construction.

If you do need just very basic DC you can use a few comparitors into various
AC generators in front of the sound card pre amp -
1] Several oscillators - 0V gives a low tone, 3V gives an intermediate and 5
V a high tone (audible as well as visible on the PC screen.
2] A low amplitude, highish frequency tone (appears as a thick line on
oscilloscope program) can be mixed with the output of preset amplifiers (The
line is level shifted).

The first is often best for PICs, especially if you monitor the audio, you
can quickly get to recognize Lo, Hi, rail-to-rail pulses, rail-to-mid
pulses, etc.

Bye.

Dave,
A few months ago, I bought and built an oscilloscope kit from
QKITS.com which it very similar to the bitscope product. Check
here:

http://www.qkits.com/serv/qkits/velleman/pages/K7103.asp

The actual manufacturer is Velleman.  Go here and search for
the K7103.

http://www.velleman.be/

Like the bitscope, this unit is PAC based.  It has 20 Mhz
bandwidth so it can only resolve signals of 5 Mhz or less but
it has done everything I've needed.  It is PIC-based and
available as a kit or pre-assembled.  As a kit the construction
was simple and enjoyable and the components are top-quality.
The on-screen user interface is identical to a regular scope so
it's easy to use.  Plus, it is great to be able to store and
print the screen output. They also have some higher bandwidth
units in assembled-only form.

Good luck and let us know what you get and how you like it.

Cheers,
Andrew

Hi Scott

I received the two 7000 plugins from you today. Thanks for the quick turn
around.

The 7D13A was the one I've been wanting to get for a long time. I never
seem to have enough DVM's on the bench and now I have one no one can
"borrow" or walk away with.  The calibration compared to a HP 6.5 digit
bench DVM was spot on. Works great. Thanks.

You mentioned earlier that you might have pdf manuals for some of this
equipment??? Any chance that you have one for the 7D13A?? I would greatly
appreciate it if you could email one to me if you do have it.

In any case, thanks!

market, but in my opinion at the time, it was worth the extra.

hope that helps.

'[BUY]: British Telecomm jacks: where to find them?'
2002\01\16@191342 by Dave Johnson
picon face
(this is a repost, sorry for those of you that see it twice. I got a
friendly reminder that the colon after the topic marker is
required...)

I'm trying to locate a source for British Telecomm jacks to mount on
a PC board, and having no luck. Does anyone out there know where I
can find them? The spec is BS6312 for one of them: there's also a
"left handed" version, I don't know the spec number offhand.

I'm in the USA, so I expect I'll have to order them from overseas
(which is fine). I know they exist, I've seen them, I just can't seem
to find any manufacturers...

Thanks for any help,

Dave Johnson

Dave,

try the following suppliers of electronic components in the UK:

rshttp://www.co.uk  (URL looks funny, but it is correct)
http://www.farnell.co.uk
http://www.maplin.co.uk

the first two are more geared to business users, while maplin is
more a consumer/hobbyist source (tho' it seems to have gone downhill
recently imho)

Farnell do them: 146-990 146-993 146-994 (they're in the catalogue under
"Office - Telephone Equipment" rather than "connectors"!)

Do you actually mean the BT603A female connector? Most telco equipment over
here uses an RJ11  jack and a line lead with RJ11-603A plug.

Go to RS Components website at rshttp://www.com and check out stock numbers

Thanks for the help with the jacks. I'm really looking for the
manufacturers, not distributors (this if for a commercial product, so
I need them in large quantities) but the distributors are a good
starting point. ITT Cannon seems to be one manufacturer, and another
is Ringtel electronics. If anyone knows of others offhand (what are
the chances of that? :-), please let me know.

Just FYI, this isn't actually for a telco application. There's a US
manufacturer of sensors for science education
(http://www.vernier.com) who uses these plugs on their sensors,
partly because they are excellent connectors (good contact and very
robust in the hands of students :-), and also because they come in
left and right handed versions, so different connectors are used on
different types of sensors. We (http://www.imagiworks.com) make
PIC-driven data acquisition modules for handheld computers, and we
want to mate directly with these sensors in a future product.

Thanks again for the help.

Since Newark is failing me now, I need another source for this pressure

before ordering.

Any sources/leads?

I second that!!! I ordered my warp-13a programmer from him. Price
was good (considering shipping and included US-compatible wall wart),
speed was good, and support was GREAT (I emailed him some silly
newbie question I had, and he responded within an hour with an
informative and useful answer). He stocks a lot of cool parts and
kits and things, I recommend a look!

About a year ago I happened upon his site while searching for information on
PIC's.  I thought his prices seemed VERY reasonable.  I have not ordered
anything from him yet, but I am pleased to know that his service is as good
as the prices.  ;-)  I went with the Picall programmer (from Amazon
Electronics, IIRC).  It works great.  ;-)  No "coasters" made yet.  ;-D

That and the fact that there is still a valid patent on them (they were only

Give it a few years and they'll come down in price even more. Every year
(year upon year), when I read the new components catalogue I'm amazed at how
much blue LED prices have dropped (okay I should get out more!).... So if
you think they are expensive now...... White LEDs which came out a couple of
years later as (I recall) should show a similar decrease in price. At the
moment they're a bit painful on the budget...

I guess the technology to produce blue must be different, cause it would
take some mental coaxing to get me to accept that one can now patent
a color.  That and the fact that R/Y/G has been around for so long, but
not blue.

Last time I ran into a hard-to-accept patent, it was the PBJ.

True, It's not the blue itself, it is the process used to make a diode in
such a way that it happens to emit blue.  IIRC, it wasn't easy, many
researchers had tried and given up.  There are limitations in the
semiconductors needed to emit such a wavelength that was ridiculously hard
to fabricate and get reliable, due to the elements involved in the fabbing.

And you have a point, if you don't like the price, pick another color.

I have a blue display on my office stereo. It looks "cool" but it is
a horrible thing to have to read from any distance (like the eight or
ten feet to my Aeron chair). Look at tall office buildings with blue
logos on them sometime- much more blurry than the red colored logos at the
same distance. Blue LEDs, yes, but for displays f'getaboudit.

       Yes, I have noticed that too, I believe it has something to do with our
eyes, perhaps they just aren't tuned to focus in on the blue part of the
spectrum in low light conditions (which tends to track since red displays
are as sharp as during the day). TTYL

The problem is chromatic aberration.  Blue light is bent
more than red light by the lens, so the blue focus point
is in front of the retina when the red light focuses on
the retina (or even more in front of the retina in my case).

I don't know why red is right and blue is focused short
instead of blue being focused right and red focused long.

And red is a good color to use in poor light condition, where eyes need a
rapid shift from light (red) to darkness. Inside ship at day the lights are
white, and at night (no laught!) are red, so when people go outside, and is
a black night, the eyes accomodate faster than with other light color.

Also i don4t know why.

Because your eyes are the least sensitive to red light (as far as pupil
dilation/contraction is concerned).  IOW, red light does not cause your
pupils to respond as much as bluer light.

Missed part of this thread, so sorry if this went past, but I'd like
to know what's the best LED color for dashboards, and viewing
in indirect sunlight.  I remember seeing a study about this some

It makes you wonder what the world would look like if our eyes had a flat
response. I read somewhere that for red light to look the same amplitude,
it had to be same large number, like 1000, times brighter. This makes me
imagine how painful a sunset would be. :)

If you look for the CIE charts and know what the wavelength is it's very
easy to figure out
the effective output of a color. For example a green might be .785 while
the red is .48
and a blue .28. In other words if you had a 100 candela white, the red
would appear to output
78% of that and so on. There are some colors that are under 1% effective.

There are a couple of other standards but the CIE one has been around since
the mid 30's
and is generally accepted by everyone.

He should have said "iris" instead of just "eyes".  The retina (the imaging
part of the eyes) is most senstivie to green as you said.  The iris (the
automatic F-stop adjustment) is least sensitive to red.

I ended up building a coil winder for the purpose.  There is a DC motor
which I control with a variable power supply that actually rotates the
coil, and a servomotor that moves the winding wire back and forth across
the face of the coil.  It also has a counter so you can wind an exact
number of turns.  The whole thing is pretty simple, if you can't find one

There's a book on making a coil winder available from Lindsay for cheap.
I don't have it, but it's supposed to be useful.

Here's a picture of a hand-operated one I made from a film reeler I got
at a Disney auction (the handle is geared about 3:1 to the bobbin
holder). I have a digital counter on it with an optical pickup, and it
is mounted on a sturdy base now. The box of Vachon Flakies (sp?) in
the background of the bobbin holder provided vital energy and essential
Polysorbate 80 to fuel the machining process.

http://www.trexon.com/graphics/winder.jpg


You could also use a small lathe with a counter (electronic or the
flip-lever type) and do it by hand.

Frankly, for such a small quantity, you don't need anything special.
If we had many to do, I'd pick up a CNC winder new for about $3-$4K,
which would be great for production into the thousands (quick change-
over due to the large number of programs), but it's not very attractive
compared to just buying completed parts.

Lawrence,

What diameter of wire do you use? I need to wind precise coils of up to 4000
turns using 38um (approx 1.5 thousands of an inch) diameter copper wire. Up
to now I've been using a rather large coilwinding lathe which I've modified
for the purpose. The results are reasonable but the winding is difficult and
time consuming and I'd dearly like to build something specially for these
coils. Do you have plans you could share?

Thanks

No such LCD exists, except perhaps in IBM's labs.

The highest resolution LCD you can buy right now has a maximum
resolution of 200 pixels per inch.  An article about it can be found here:
www.extremetech.com/article2/0,3973,525370,00.asp
Viewsonic sells them, 22.2" displays with a resolution of 3840x2400.

You could purchase LCD's meant for projectors, but mostly those top out
at 1024x768.  Actually, now that  think about it, your best bet is
probably to get a 3 LCD projector that has as high a resolution you can
find (1600x1200, perhaps) since the LCDs themselves will be monochrome.

Out of curiosity, what do you need such a high resolution LCD for anyway?

Sorry to let you down but its not possible today or any time soon.  
  10 CM is 100,000 microns.  This would give you 32 micron pixels.
This is easily possible with photo-lithography but because the
resistance is high for indium tin oxide, the clear metal, used to make
the capacitors in the display.  You also need a 6-10 micron pixel gap.
Also this doesn't take into account the space for the LCD trace routing
and glue seal which would also cut down your size.  
You can't buy LCD Drivers buy drivers that have that many I/O, max is
about 250 per die.  Also the pad size is limited -- ~50 microns per pad.
So bond space for the drivers would be bigger than the display active
area.

With Poly-silicon TFT technology this is possible, but not yet available
and expensive ~ $60-$100 in very large quantities.  With Poly, the
drivers are built into the "Glass" (Actually in the poly layer itself).
They want to mostly make color anyway.
You could easily get 128, 256 x 64 or by 80 in graphic LCD.  Cellular
phones are about this size.  
One place to get a high resolution display is from one of the LCD on
silicon (LCoS)- Heads up display people, Three Five Systems, H.P. or
Colorado Micro displays.  Probably you could buy a prototype - but
probably not monochrome and not cheap.   They are also 1024x768 or
similar format and smaller.
These are used in rear projection TV's and camcorder viewfinders.  Check
out http://www.threefive.com  where you can read about them.  Also check out
ww.sid.org for general display links and information.  
Also you have another problem with the multiplexing a passive STN's are
limited in resolution.  So you need a TN cell with active matrix drive
to get that kind of resolution.  
In short your resolution is way too high to fit into that space.  Even a
desk top LCD is only on the order of 1024x768 - so 3x this for
monochrome in a 15" display.  IBM showed a research model that was
higher density, but not a production model. Most people who want TFT's
want color, so most high resolution, small displays are color.

Thats a very high resolution in a small size!  Do you realize that the pixel
pitch is only 100mm / 3200pixels = 0.031mm/pixel?  Normal color CRT monitors
are in the .22 to .28 "dot" (triad, actually) pitch range.  Another way to
look at what you are asking for is in terms of DPI:

 3200dots / (100mm / 25.4 mm per inch)
 = 3200 dots / 3.94 inches
 = 813 DPI

This seems rather absurd.  What are you trying to do?

Ye gods.  The only place you have any real chance of finding an LCD

The only people that would even think about making something like that--

Hitachi, probably in that order.

This should be fairly simple.  Can you give a few more details such as the
range of input frequencies, and the desired output frequencies.  I wrote a

a small amount about electronics; however PICs appear to be over my
head.  I'm a software developer (on Linux).  Anyway, I'm looking for a
circuit that can create the timing indicated on the attached gif.

Time t could be any value from a few seconds to a several hours.  Once
major concern that I have is how much current the circuit will draw
(from a car battery) while it's "idle".

Preferrably, I'd like a completed circuit and code that I can use.  The
3 output pins will drive relays that can handle about 10A.

I'm willing to purchase a PIC programmer and learn how to do this
myself, but I'd prefer a complete/working solution.

If anyone is interested in making some easy money (I doubt this circuit
is too complex), please contact me with an estimate.

One thing to note is that I've already figured out the B output so it's
not absolutely necessary; however, if it can be done trivially with a
PIC I would appreciate it.

Yet another concern of mine is the PIC language.  I'll accept any code;
but my preference is for C code (that I can possibly expand upon).

Please email me to discuss (off list or on-list if that's more appropriate).

Much thanks in advance...

Hi!, Im a Microchip consultant program member (check it at micrchips web
site) and would like to do this job for you if you like. I'll charge you
U$S 400. If the price is all right with you, I would like to discuss
what exactly do you want and everything else needed to finish the job.

'[BUY]: LM566N VCO's'

I need 200 pieces of either the LM566N or NE566N or XR-2206 (I think). They are VCO's . I designed a board a few years ago using 2 of them to create a siren sound. I know, I should have used a PIC. Who knew? I want to use up my boards before redesigning around a PIC. BTW anyone have any suggestions on creating good clean siren sound with PIC?

Does anybody know if the Kenwood DCS8200 Oscilloscope is any good. I
allready have an analog scope but am looking for a digital one. Someone
has offered me this scope and i would like to know if there's anyone who
can tell me a bit about it. I haven't found much info on the web about
this thing so ...
