Yeah, I just went out to the garage and I couldn't find an AVR programmer. How 'bout a simple on/off switch? LED's are pretty efficient...I imagine you could run it off of one AAA.

Inordinately complex things make the world better. Also you could just use a tricolor LED and three mini potentiometers - PROBLEM SOLVED.

If I were to attempt an LED in a coaster, I'd start by taking a cheap one from a keychain or something, along with the switch that comes with it, and try to re-house it as-is.

I agree. I think once you got the coaster housing and the switching mechanism down, that'd be most of the build. Photon keychains are $6.

I'm usually a "build vs buy" guy as I like to mess around but for $2.86, it's been done:

How about making a line of 8-10 light-up coasters on the bar, all connected through whatever it is that does the Christmas-lights-to-music? Then, your beers could flash different colors to whatever you have playing?

I'm kidding.... well, kinda....

Epilepsy - it would kinda bring down an evening.

Well, with enough time, and some voltage regulators, one could hook this idea up relatively easy.

EDIT ->Trying to keep up with what is where has worn me out. I have beer in all phases at all times and just don't feel like updating this anymore. Want to know what I have going on, just ask, or come over and have a few!

That would be amazing. You could set it to some Trans-Siberian orchestra just like they did on that youtube house. And use different types of beer for different colors....
