What exactly do you mean? You want to build some project and program it yourself, or use an arcade one. Assuming you mean you want to build a project and program it, you're not talking about a PCB, you're talking about a microchip. There's places that sell cheap programmers, such as Jameco or a local store, but you can also DIY. I havent found a schematic, but Ive heard/seen somewhere that it basically consists of resistors. You send a signal through a port on your computer and it is sent into the chip, no biggie. If anyone finds a schematic for a DIY programmer that works, I wouldnt mind having a look!
