I follow @luke.the.maker on Instagram and I loved his Midi Blaster that he posted about! I was super excited when he released the instructions on how to do one for yourself for free on his Patreon site: https://www.patreon.com/posts/midi-blaster-v1-126826036
If you havn’t heard of the MidiBlaster, it’s a kind of portable music player that Luke The Maker made that use an USB-floppy + RPi4 + speakers to play midi-files with custom soundfonts from floppy disks.
However, I didn’t have the exact same USB-floppy at hand, I only had a RPi 3 and I wanted to use the MidiBlaster together with my stereo receiver instead of using built in speakers. So I, naturally, made my own variant!
If you too want to make this variant, you download and follow Lukes instructions. But instead of 3d-printing his shell, you can print mine here:
It’s made up of three parts and can be printed on a relatively small 3d-printer (I used a Flashforge Adventurer 3).
Lukes files and instructions use Raspberry Pi OS, so they should work with pretty much any model of RPi and USB-floppy. However – I noticed that the pinout isn’t exactly the same on the different RPi-versions, so the pin for Play was not the same on my RPi3 as it was on Lukes RPi4. Other than that everything worked smooth. It takes a while to boot though…
