View Full Version : I'd rather have a broken Demoboard than a working Arduino

Just for the fun of it, (and because my project is starting to irritate me)
I pull out the three "BAD" demoboards I found left on the freebie table @ UPEW
and starting looking into what could be repaired.

Naturally, the rest of you guys left the last three because they looked the worse. :)

Just got one up and running with everything except sound.
So, yes.. I'd rather have a broken Demoboard, than a working Arduino. :)

Anyone else get interesting stuff on the Freebie table this year?

The "freebie" table is becoming a fun tradition for the Unofficial Propeller Expos.

It's a large sharing of parts from attendees. Parallax dropped a LOT of freebies at UPEW.

One man's trash is another man's treasure. :)
(Attached is an image from UPEW: Ken's trash is a good time. :)

I have noted a few attendees took a few broken demo boards and now have them working. BUT, even better, they are giving them away to new homes, so we will have a few new prop devotees soon. Fantastic guys http://forums.parallax.com/images/smilies/smile.gif

Yes, the freebies table was fun!· I grabbed a couple of bad demo boards too - haven't tried to see what's wrong yet (except that one obviously has a huge solder bridge on the VGA connector - maybe that's the only thing wrong!).· Other than the demo boards, the things I was excited to see were a bunch of 74ACT373 (octal latch)(*) and ULN2083 (relay driver) chips - all SMT.

(*) The ACT373's are TSSOP-20, i.e. tiny little things.· Between Saturday night and Subday morning, someone at the UPEW thought it would be fun to dump the several hundred of them out of their tubes onto the table and mix them with several hundred SOIC-8 2K EEPROMs!· I just scooped up a couple handfuls of them into an antistat bag that was lying around.
