64-key MIDI Matrix – Part 1 – buy the TWO PCBs HERE and HERE
This simple project turns an Arduino into a MIDI key matrix. These are popular with musicians for triggering samples, but commercial versions cost hundreds of pounds. Ours costs a fraction of that, and you can customise it by changing the Arduino software. It supports regular or illuminated buttons and can also be programmed to act as a MIDI pass-through, among other roles.
Digital FX Unit – Part 1 – buy the TWO PCB options HERE (BCD) and HERE (pot)
Make like a pro muso with this Digital FX (Effects) Unit. It will produce unique sounds when connected to a variety of instruments… like an electric guitar, bass, violin or cello, even the output of a microphone preamp or within the effects loop of an amplifier or mixer.
High-current Battery Balancer – Part 1 – buy the HERE
Proper balancing is critical for a long battery life, especially if they are lithium-based rechargeable types. But many balancers are inefficient, as they dump excess charge for a given cell, restricting how fast you can charge the batteries and wasting power. Not this one – it redirects that extra charge into other cells, so you can charge fast with little heat or waste!
