MSA-R MIDI Decoder

This kit gets top marks for ease of assembly and low price, and because it’s preprogrammed to do all the heavy lifting, all you need to do is solder it together and attach it to the device of your choice. It’ll take an average-skilled solderer 1½ hours to assemble, and from there the possibilities are endless. Circuit-bent devices, kinetic toys, and things that light up can all be linked and sequenced into a sound-and-light show that’ll impress onlookers with your ingenuity and resourcefulness. And it’s fun!
