L.e.d.............lighting...

Ok good, you were paying attention and gave alternative design a try. But just using an AC source like that is a little like cheating, because it's not that simple in real life. Try using the astable circuit from before. There are a few examples around if you need a bit of inspiration. Think big, and get your blinky on!..

My issues aren't with using AC, per se. You've got 24 LEDs here, but it's kind of a hodgepodge as to how they're getting power. (Not to mention the source is 1V at some ungodly high frequency.) The way I see it, run each color of LED in series (6 if them), then branch those 4 strings off in parallel with the power source. 2V LEDs, x6, you'll need 12V. No big deal. Get a transformer and set step down to 12V from standard 120VAC. Yay, it works. I still don't like it though. The LEDs don't stay lit up for long. That's an easy fix, too. Step down to 18 or 24V, then throw in a resistor. Now the LEDs are getting the correct account of power, and they stay lit for a reasonable amount of time. Cool. Now here is my issue with using AC: It's all happening at 60Hz. That's way too fast to see anything happening with the naked eye. So we've got to try something else...
