USBtinyISP

My new pc doesn’t have a parallel port anymore so I couldn’t use the AVR programmer I made before. That’s why I decided to build one that works on a USB port.

The design is based on the USBtinyISP design from http://www.ladyada.net/make/usbtinyisp/index.html I removed the 6p connector from the circuit because I don’t use that. And I’ve made a new print that is single sided.
