'[OT] What to do with a bunch of old circuit boards'

Hi List,

We have a bunch of assembled circuit boards that became obsolete when a new
product came out. People still buy them once in a while, but at the current
rate we'll still be selling them in 2014, and we need to take them off the
books, one way or another. Putting them in a crusher seems like a waste.

Here's the product page:

http://www.scantool.net/scan-tools/elmscan-pwm.html

And here is the schematic:

All suggestions are welcome.

Maybe directly target a forum dedicated to the vehicles this product was
aimed at. ?

If it was for Vauxhall / GM / Opel I could give you some ideas but they
appear to be mainly Ford based.

Vitaliy,

You could possibly give them out as door prizes for some event locally.
Or you could check you local High School or Community College to see if
their automotive department could use them.  Or even a local trade
school.
It seems to me there would be several possibilities locally.  Even more
statewide, or nationally.


       
Regards,

       
Jim

Set up a group buy with a local Ford Mustang (or similar) club?

What I see from the forum, it works on many other brands of vehicles
also. Looking at the web site, I see a PCB, 2 cables and a CD, no case,
is that correct. Incidentally, I have had an AutoXray unit for years.
The next thing I see coming is a unit to set the tire inflation monitors
when one rotates tires.

Can't possibly sell all of them (1000+) this way, more hassle than it's
worth. :)

Sorry, I should have been more clear.

We need to get rid of the circuit boards *only*, they do not include the
ELM320 chip (which can be purchased for $15 or so from Elm Electronics).

Of course, someone could buy the boards, and build them into scan tools (buy
the cables + install the ELM320), but if we can't sell them I don't think
anyone else would be interested. There are 1000+ boards.

We'd be happy to give them away to a school, but I doubt they'll take them
all. Do you know any schools in your vicinity that would be willing to pay
for shipping the boards to them?

Bare boards?  Or Partially stuffed?

Well, it looks like the ELM320 is an 8-pin PIC, making the board
POSSIBLY "bendable" into a general purpose "8 pin PIC with a crystal,
voltage regulator, and rs232 interface, (plus two other pins connected
to "funky" electronics that you need not populate, and could connect
to other things.)  You might be able to get rid of them documenting
them a bit along those lines...  Potentially you don't even need to
populate the crystal - the PCB has nice holes that you could use to
connected those to something else.  But having the voltage regulator
and rs232 interface is sorta handy...

Heh.  In the worst case, if they're bare boards, you can offer them up  
as "3x4 inch pieces of G10 fiberglass (some holes, markings and  
copper.)"  People BUILD stuff outa that, and it's annoyingly expensive  
to have to buy...  Weird lamps and sculptures, model rocket fins...  
I've taken home uglier looking blank PCBs with an eye toward that sort  
of application...)

Stuffed. I took pictures of top/bottom so you can see exactly what each
board looks like:

The crystal is 3.57Mhz (an odd frequency, to be sure). The ELM320 is based
on the PIC12C509, so I guess the board can be used as a GP board...

Vitaliy,
You need to get out more!  ;>

That is the color burst crystal for NTSC color TV systems.  Dirt cheap.
 Probably was designed into your board due to it's low price.

I've ignored this thread up to now but knowing that the board is pic
based makes it more interesting, at least to hobby folks.

It has a socket for an 8 pin DIP PIC chip; hobby people on this list
often indicate a preference for dip over smt.  It has a crystal that can
offer an accurate time base or it can be removed for one of the pics
with internal RC oscillator freeing up two more pins.  It has both a DB9
and a DB25 connector; if nothing else, it could be made into a "quick
brown fox" generator.  It is built and waits only for a users pic to be
inserted.

If it had been me, I would have asked piclisters for ideas of what to
use it for, (maybe even contest fashion) with prizes (these boards) to
the best ideas.  As an engine diagnostic tool, it appeals to a limited
set of users but as a cheap breadboard for generic 8 pin pics, it
appeals to a much larger group.  And finally, if I were teaching
embedded controller classes in high school, college, etc, I would try to
get the entire stock to have students use for class projects.

LED flashers, beepers, signal generators, where to stop?

They would be great for learning on. Try and make them available to the pic
list?
Thanx

I'm all for it. How to do it I think is the question.

Probably one of the commonest crystal frequencies around these days (NTSC
colour subcarrier for TV). A lot of chips were designed to use this
frequency, quite common in modem chips as I recall, as well.
