This cool new DMX module from Tinker (the team behind the immensely popular Arduino controller) is a device that can receive DMX messages and control many different types of lights. It is powered by 12 volts DC and set inside a DIN enclosure. DMX messages are converted into PWM signals driving 4 power MOSFETs and DMX address is set via the onboard DIP switches. Pretty cool piece of hardware with some code samples to boot!
