Two nice project i found recently:
this is a pcb to create your own GC controller. Main use is to integrate it in a Gamecube or wii portable.

Do not forget to have a look here for most recent firmware or to buy pre-build boards.

This one is a usb to gc converter with the ability to use a Bluetooth adapter and connect a DS3 or DS4 to have a good and cheap substitute to a wavebird.
