Re: Source for "bump-resistant" SPDT switch?
I've used Alcoswitch (Tyco) MTL series before on an electric guitar. It's a small toggle, but you must pull out on the lever to change positions. Won't move when it is accidently hit. About ten dollars at Newark. Tyco has lots of distributors though. Let me know if you need further info. Regards, Dave

Re: favorite suppliers?
Edmund Industrial Optics also has a cool "wish book". All kinds of lenses, lasers, and fun stuff.

Re: any info on a sharp IC "IR2406"
Ray, That was a tough one. I couldn't find anything on my extensive searches thru the net. Thank God for my library! I have a 1985 Sharp Databook with the IR2406. I'll be happy to PDF the three pages and email to you. Is your hotmail address still active? Let me know where to send it. take care, Dave

Re: non-polar capasitor value reading
Did my last post answer your question?? Except of course, you should be able to infer that the 223K100V is a 22,000pF = 0.22uF 10% 100V (not listed in your original question). Respectfully,
Dave

Re: non-polar capasitor value reading
By George, I think I've got it! Thanks Dean. I know (or knew) all of that stuff, but I've never seen it all in one place and stated so clear. From your post I would gather..... 2A472J = 4700pF = .0047uF 5% 2A104K = 100,000pF = 0.1uF 10% 2A104J = 100,000pF = 0.1uF 5% 2A103J = 10,000pF = 0.01uF 5% 100...

Re: looking for a voltage tester
Tenma has a cool circuit tester I have used before. It just has lights for checking polarity and GFI circuitry. If you "duct taped" an analog meter to it... you could tell your boss that you checked voltage, polarity, GFI(If applicable) and promise that there is no incoming interference fr...

Re: looking for a voltage tester
Newark has a "Jewell" analog meter. It's 1-1/2 inch square. Is 5% of full scale accurate enough?
P.N. is OMS-AW-150-U or OMS-AW-300-U for $19.00.
Otherwise, I'd buy a cheap credit card sized digital MM and use duct tape and bailing wire to attach a plug to it!!!
Good luck,
Dave

Re: Battery check
I agree with JWAX. Maxim has a ton of voltage monitoring devices that are super super small.
They are also pretty good about sampling.
Best of luck,
Dave

Re: Voltage Ladder
Stun Gun projects utilize the same sort of circuit. At least the one I built did many years ago. Adding more and more caps and diodes was a cheap and fun way to get more and more excitement/danger.
Good luck,

Dean, I try not to reply when I have nothing additional to contribute. In this case I have to reply. Thanks for the very well written post that echoes my sentiments exactly!

Does this help any? Are you referring to the marking on the parts?

Whoops, I should have been more specific. I'm not a morning person!! I meant to say a ZENER diode (5.6V) Parallel anode to cathode/cathode to anode. In normal operation, the diode doesn't conduct, just the LED does. If the LED becomes an "open" then the diode (less the diode drop) lets cur...
