Meant to be a cost-effective first step in making music, the Rhythmo BeatBox is a DIY affair. It uses a cardboard box as a platform and leaves it up to the future performer to assemble it (no soldering required). It can be built in under one hour and uses an array of arcade buttons, knobs, and a joystick for control. A companion app handles much of the sound processing, and it also can serve as a standard MIDI controller. Creations can be enjoyed via the built-in speakers, through headphones, or through external speakers attached to the headphone jack.
