Where can I get me one of these?

http://www.pinrepair.com/sys80/clock3.jpg

One the site, it's mentioned that it's a "Radio Shack" probe, but I couldn't
find it anywhere.

Any help is appreciated.

After some digging, found this page:

http://www.linuxtoys.org/pscope/pscope.html

which had a link to the manufacturer's website:

http://www.wittigtechnologies.com/english/05_products/01_oszifox/oszifox_02_specs.htm

The problem is, I cannot find a place to order the thing (not even eBay).
Has this product been discontinued? Are there other similar probes on the
market? Does anyone have one for sale? :)

UPDATE: Just called the number on the website (to see if the company is
still in business), and someone actually answered the phone (it's 2 am in
New York)! The person on the other end of the line was apparently expecting
a call from someone else, but he politely confirmed that the OsziFox has
indeed be discontinued and there is no replacements... what a shame, looks
like a neat little probe. :(

Radio shack did indeed sell it. I bought mine when it was discontinued
some years ago.  Low resolution, etc, but handy in the field.  Needs
to be powered from 12V-ish that is common grounded with the system
under study.

Damn... When the "cheap oscilloscope" thread started a week or so ago,
I checked Ebay for oscilloscopes, and some "probe scopes" like that
were readily available.  $10 - $20.

Today, however, I can't find them.   Keep an eye on "oscilloscope" on Ebay.

Here's a promising link:

They claim to have the osziFOX, but it may be an old page...

I think you'll find it's a *very* old link  :-(

I seem to remember having one of these (or did I just want one?  My memory is getting dreadful!) and it was at least
ten years ago - I believe the software that came with it was for DOS, Windows 3.1 and the new-fangled Windows 95...

It's a shame that it wasn't updated, or replaced by something better, but that's Marketing for you.

I have a Velleman hand-held scope for the sort of things that the Oszifox would have been useful for, but its name is
only valid for large sizes of hands!  :-)

With the hardware/software talent on this list, why don't we just design
our own?

You can have mine, if you want it.

I purchased one from Radio Shack on one of my trips to the US several
years back - after seeing it mentioned on this very list.  Played
with it for a while, then just let it sit on the top shelf of my
workbench.  Its been there for a very long time.

Its a neat toy and is even somewhat useful but I much prefer my Tek
THS720P <grin>.

Turns out that if I think I'm going to need a scope for something,
I'll just grab the bag with the Tek in it rather than try to find
room in my already over-crowded tool bag for the Osziscope and the
8-AA battery pack I use to power it.  I figure that if I have to pack
a bag just for the Osziscope and battery, I might as well take a real scope.

Your mileage may vary.

Freeping creaturism runs rampant...  (feature creep - the requirements
will never be agreed upon)

Also, there just isn't that much utility in such a device.  Try to
make it powerful without a complex user interface, in a large pen
size.

How about we start with the LCD font?  Did Scott ever find a nice one
(thread a few days back)?

There's a page out there somewhere that describes a 16F84A (naturally!)
based DMM, built into a RS probe body like that.  Volts, ohms, frequency,
capacitance, logic etc, but uses 7-seg displays.  Called something like the
'parrot super scope', it's been a while.  Google will turn it up eventually,
or http://www.piclist.com would have a link.

Don't Velleman have a 'scope based on a 10x10 LED array?  Get a few of those
tiny 8x8 arrays, that'd be neat.

Did that years ago (decades!) with 3914 chips and a 10x10 handwired grid.
Pretty cute with music, but needed more resolution.

Pretty good, but hard to really see the patterns at 10x10.

Later I redid it with matrixed displays, MUCH less hassle, and put it
in a nicer frame with red plastic over it.  It's still around here
somewhere.

Was in pittsburgh this weekend, saw LED based billboards in full color.
Boy, things have come a long way.

Neat, but rather bulky. Plus, we have a DSO.

This probe is mostly for bench use. Digital scope is useful, but for quick
checks the probe is more convenient (don't have to take the eyes off the
board). I think it's cool that you have a screen that gives you an idea of
what the signal looks like, rather than just three LEDs.

I've got a half-working prototype of its successor sitting on my workbench,
awaiting firmware, CPLD bitcode and a better LCD. Unfortunately I'm severely
lacking free time - hopefully I'll be able to find some between May 16th and
July 1st to finish the damn thing off.

The aforementioned logic analyser was going to get entered into the second SX
Design Contest, but I didn't get the firmware going in time. Too many nasty
bugs to kill. Mk3 uses a PIC18F, and has an MMC/SD card socket (which also
doesn't work at the moment).

I wanted to add an A/D converter to it, but the design of the input circuitry
is close to being something of a black art... 50MSPS with 20MHz bandwidth was
the design goal. Big problem ATM is lack of time, and lack of test gear (I
need a signal generator that can do sine/square at 0 to 50MHz ideally), in
that order.

Feel free to bitch about how long it's taking, but expect a snippy, mildly
abrasive reply to the effect of 'university work comes first'.
