Ok, bit of explanation first. We have a PC set up as a 'democratic jukebox' at Hackspace Manchester. The idea being that anyone can put music on it, and it plays the entire library on shuffle during our hack sessions for a bit of background music.
The problem is, of course, some people have an... odd taste in music, so sometimes the jukebox ends up flipping between Aqua and Cannibal Corpse for ten minutes, and the horror of this was just too much!
Enter the PANIC button.

The button uses a minimus board. The minimus is a carrier for the AT90USB162, an AVR microcontroller with onboard USB hardware, which means it can be programmed to show up as any USB device.
Before getting the button I modified one of the pieces of LUFA demo software, a media keyboard, and stripped it down to just read the one button on the minimus. When the button is pressed, it sends the keycode for next track.

- Hold down the HWB button, then press reset
- It should show up on the PC as an atmel DFU device
- On a linux box with avr gcc and dfu-programmer installed, just type 'make dfu'.
