You can get a full wave bridge rectifier already wired (saves all of that wiring and soldering) for as little as $0.50 each. Add a capacitor and it becomes a constant lighting unit which will work on either A.C. or D.C..

I put several together and the total was less than $1.00 each.

Don't stop there. How about some details?

I bought diodes in bulk, plus I can arrange them on a board as needed. I would like to see the board you use. Is yours for any specific scale?

This concept has been discussed before. Here is a link to the thread.

A 1.4 amp diode and 680 uf capacitor. Got it!

I just like to see what people are using.

I tagged the thread as LED constant.

I use the CL-2 constant current source for truly constant intensity LED lighting. If I want more current for multiple LED's, I use an LM317T in a constant current configuration.
