3D PRINTED MIDI DRUM CONTROLLER DIY PROJECT

Working making a 3D Printed MIDI Drum Controller DIY Project

Similar to the commercial units available via Akai, M-Audio, Native Instruments.

Update: I got accepted to present at World’s Maker Fair NYC and then made a mad sprint to finish this project, the parts I used are different and the 3D printed files changed. I finished a new 3D printed enclosure that is wired by hand and produced a laser cut acrylic enclosure for this that has a PCB designed. More information will be forthcoming, please email me at kr1st0f@ayatomm.com to get on a mailing list for updates. ┬áMy apologies for not having all the information readily available.

FLAT_FLEX_CONNECTOR

The trick here is the Flat Flex Connector to interface with the sensor pads.ADAFRUIT PN: 1325 Adapter works for this

RESISTOR_ARRAY

Resistor Array voltage divider. Put 5V on the common bus of the sensor pads, the individual outputs you wire to two things, a resistor array that has a common bus tied to ground, and the analog input of your microcontroller, in this case it will be an Arduino Leonardo. Pictures of a schematic will be forthcoming.
