Polyphonic DAC with teensy 3.6

https://github.com/brorgustav/polyphonic_dac I’ve spent the last days working on Arduino code for a polyphonic 6/12-voice DAC (from USB-host midi keyboard) with mcp4822 chips and a teensy (connected to AKAI LPK). This code is a work in progress (but works) and shouldn’t be considered stable. It’s with a teensy 3.6 and USB connected to USB-host pins. The …

Tubes on low voltage

So i recently got interested in using tubes on lower voltages and incorporating into designs. I found out that there are some designs primarily with 12AU7(called ECC82 in europe), for example a link to the most popular one, The valve caster: *document with summary of the original design and some user modifications *a more beginner …

This could make it tedious designing into panels aswell since you’d have to use a OTG cable integrated into the design or something similiar. …

Converting a MIDI-USB keyboard to BLEx

I’ve started working on a simple project for converting my MIDI-USB keyboard to BLE midi with Arduino. The USB host library for m0 arduino is under development so i wouldnt call this stable at all but i’ll share some code anyway and hope someone find use for it. Components i use: Arduino M0 pro (Or …
