MIDI Biodata Sonification Device – Settings menu for the MIDI Sprout

The MIDI Biodata sonification device (also known as MIDI Sprout, by DataGarden) is a great device to make music using plants. Here I describe how to apply the firmware of the very similar Biodata Sonification Arduino shield to a "classic" MIDI Sprout. This includes adding a button to gain access to a settings menu which allows to adjust MIDI-Channel, LED brightness, note scale and finally the good old threshold. Sam Cusumano, creator of the MIDI Sprout gave me the idea (or challenge?) to do this: "And if you REALLY wanna get funky, you can add a button to A1/gnd and use my new codebase which allows users to edit MIDI channel, scale, led  brightness, threshold through a 'menu system' using the leds and the knob. check it out on my github https://github.com/electricityforprogress/BiodataSonificationBreadboardKit which is an 'arduino shield' but should work with the main biodata board with perhaps a few code tweaks."

Packages for the Infinite Noise TRNG

The Infinite Noise TRNG is a true random number generator designed by Bill Cox (waywardgeek). Check the GitHub repository for more information about the device. There are udev rules and systemd unit files included in my packages, so the driver is started when you plug in your TRNG. Signed repositories are also available for Ubuntu, CentOS 7 and Raspbian (ARMv7) - see below. (more…)
