MIDI
About the MIDI PCB
MIDI is an open source PCB design by Tommie1236, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 80 × 42.1 mm, with 24 components from 11 distinct parts.
Other key parts include the H11L1. By type, the board carries 9 resistors, 6 inductors, 4 connectors, 3 capacitors, 1 IC and 1 diode.
It belongs with the audio and displays & leds designs in this gallery.
From the project
lighting focused midi controller
- motorized faders. Mostly for dimming controls, enough in the playback section and 1 as Master. I chose motorized so they could sync with the controlling software if the value changes and for for example if you were to switch banks to a new set of controls. (mydmx doesn't support that but i wanted to design my controller to work with almost anything.)
- Buttons. for playbacks/executors en general control, a whole lot. Of Course. what would a controller be without a lot of buttons. I also want them to have black with transparent text keycaps and rgb leds below to show the status of the…
