Jari sent in this Arduino mini based DMX strobe light controller. There is plenty of room for expansion and customization, which is good since you can control almost any DMX device with this type of hardware,
This one is a small project that I had to do twice to get right. It is a pedal used for controlling strobe light through DMX protocol. Technically it is built on top of a Pro Mini Arduino with simple DMX driver circuit. It has button to kick the action, rotating switch for choosing different presets and one switch for future expansion. You could basically control any DMX device with this hardware, but I built it for Stairville 1500DMX strobe light.
