Step 3: Build Time!
So, we can start our build of a simple all-LED + a bridge circuit to run off 110v mains.
You will need:
Lots of white LEDs - naturally! And TEST them all!
AC line cord
1N4003 diode or 200volt bridge rectifier
The first picture is what my circuit looks like when finished. Quick eyes will note that there are only 42 LEDs on board. Because of the need to accomodate the bridge on the board, and because of the relatively stable nature of our mains, we can run our lights a tad over 20mA.
The Bridge has 4 leads: 2 marked (~), a (+) positive and a (-) negative. The (~) ones go to AC Mains.
Start by connecting the Bridge (+) to the longer (+) lead of the first LED, then take the short lead to the long lead of the next LED. Do 1 row, double and triple check before soldering! Work your way down, ALWAYS connecting shorter to longer.
I have additional pictures below showing the various stages of completion. Print them out to help you do the wiring.
