I've recently been working on my skills in PCB creation. I've created one before with the help of Matt Beckler from www.wayneandlayne.com. This was my first try by myself. This kit was developed out the need for an interesting/cheap learn to solder kit. The kit has 5 LED's, a CR2032 battery, a simple switch and a ATTINY85 IC. The ATTINY85 is easily programmable with SparkFun's Tiny Programmer. See the YouTube video for some action!
