1. Designing the board / getting the files.

The FabISP is an alternative in-system programmer for AVR microcontrollers, designed for production within a FabLab. That is, it allows you to program the microcontrollers on other boards you make, using nothing but a USB cable and 6-pin IDC to 6-pin IDC cable.

First step is to grab the example files from Neil. You need three files, components, traces and interior (outline).

Although this stands for printed circuit board, the boards are usually etched or milled; also, PCB is how the substrate is referred to; when it is "stuffed" with components, it is a usually just called a "circuit board".
