Arduino based clock generator with MIDI and analog outputs!
Perfect for syncing instruments with MIDI sync and analog clocks.
arduino code here : https://github.com/alexiszbik/clockbox
4x 220 ohms resistor
3x Jack female output
2x MIDI DIN female output
1x Arduino Nano (any other Arduino might do the job but this one is cheaper)
1x Toggle button
1x 10k potentiometer (4.7 k or 100k is Ok too)
The idea of the clock box came from Eloïse & Jean from Les figurants de la peur ( https://lesfigurantsdelapeur.bandcamp.com/ ). They wanted a device that could be the central clock of all their equipment, a clock to master everything.
