Battery Booster Upgrade

Go figure - as soon as I finish soldering up my 9v/USB battery pack, along comes a better model. It uses two AA batterys, which gives you 2.5 times more charge, and features a through-hold board which makes soldering easier. And it's all published under open source.

That's not the best part. The best part is Lady Ada is also a maker, with all her projects up on the web for all the world to share. These include a full synthesizer, "persistance of vision" aka blinky LED projects including one that goes in the spokes of your bike, and an MP3 player built into an Altoids tin with a built in FM transmitter, and a bike repair stand welding project.

I think I'm in love.
