Fab ISP

For the FABISP i created an eagle file based on David A. Mellis' design with a few mods.

I inserted 3 LEDs for indicating ISP is powered, target is powered and for data as well as swapped the usb mini head for a type A usb port.
The upper jumper (SV2) is closed to power the target board while the lower jumper (SV1) is Close to program the ATtiny44 on the FabISP

I then connected the board to an MKII and with the avr studio IDE uploaded the firmware code to the chip.
