Christmas prep starts early: MIDI control for strings of lights

If you’re planning to outdo yourself with this year’s Christmas decorations now’s the time to start planning. After all, what else have you got going on since the dreadful heat is making outdoor activities a sweat-soaked misery? Take some inspiration from [Tim] who just finished prototyping a wireless MIDI controller for his strings of Christmas lights. You can just see the four spools in the distance which are lighting up as he tickles the ivories.

The wireless link is provided by a WiFi access point which uses its USB port to control the external hardware. This is a USB Bit Whacker board which in turn drives a relay board that was designed to switch mains voltages. The high voltage parts of the rig are housed in a plastic food storage container which hosts two pair of outlets to drive four channels in total. [Tim] is happy with the outcome, which he shows off in the video after the break, and hopes to expand to a total of sixteen channels for this year’s festivities.
