Selfrunning cold electricity circuit from Dr.Stiffler

[amigo]

Weekend is here, yey, and I stopped by the electronics store earlier today to pick up some parts, just to find out now hours later that Doc had posted a parts list and it shows the AVP with 1N4248 which I don't have...grrr, if I only knew that this morning when I was in the store, hehe.

So what is our next step, measuring light emission with home made instruments?

I still wonder about one thing...how do we know that LEDs themselves are not acting as photo sensors and producing some potentials that add to the illumination?
I mentioned this awhile back because I have seen circuits where LEDs are used as light detectors and produced potentials. Since these circuits oscillate with very high frequencies is it wrong to assume that in the off times, LEDs might reverse to light detection and create potentials?

Someone please correct me about the above if I'm wrong to think it's possible...

@Amigo
YOU SHOULD HAVE CALLED ME OUT ON THIS AT ONCE, the posted type is incorrect, but the part number for JameCo is correct. You want 1N4148, I will call someone and see if they can change it before they leave.

@All

If you want to try and get software to simulate the simple SEC, the following is pretty close to what you want to use.

Hi Doc,

I did not know it was a typo, I figured it was correct since there is a 1N4248 as well - at least we caught it early on.

Off to make me a full circuit with the right components, now that I have all, and see what happens.

@Amigo
If the LEDs themselves are acting in this way and that can be shown (assuming no manufacture has it hidden in a file someplace) would be a great discovery in itself.
