It's about 12 hours compressed to 3 mins of me "kitting" up some dual op-amp based "poor man's" PWM light driver.

I build the board start-to-finish. Get in the raw single sided copper clad boards, do a toner transfer, etch using HCl/HOO2. De-panel, drill, populate(all through hole), solder, test, install into a hammond case, ect....

I've sold about 120 - and have had zero failure rate. over two years so far. I honestly think it mostly has to do with how well op-amps are made today. I'm using Fairchild. It's amazing.

Anyways - I just wanted to share....Hope you liked the video.

Next up for me is to transition from basic stamps, to the atmel world - I'm a bit rusty on my ANSI C. But if you've seen one conditional loop, you've seen them all! Right?

That was a good way to spend 3 minutes cursing a bug that I can't find :-)
