The executor effects key chain is a frequently used toy for circuit bending ! But I have this sickness where i want to add a midi port to everything…
I added some 2n222 resistors to every button so i can control those buttons with a micro controller. And i used a LDR and led combo to control the pitch with that micro controller.
In this video i explain a bit more on what I did so far!
The next step would be to solder all of the electronic onto a prototyping board and add physical midi port instead of the USB midi i used till now. After that i will design and 3D print a sexy case for this instrument.

Feel free to leave a message here if you are thinking of a fun or weird design!
I see you decided to go for an arduino. I would have done the same because a teensy is relatively expensive and much more powerful, so that would have been a bit of a waste.
Yes i really like those arduino’s! At first the teensy had some advantages, but i didn’t made use of those any more. Thats why i just use the cheaper option.
I was testing to use one of those analog output on the teensy but i din’t used it in the final experiments
Naming a midi usb device is very easy with the teensy library’s its doable with a 32u4 type arduino like the pro micro in the picture but a bit of a hassle to be onest. Those teensy midi librarys are really epic! And very nice for some fast experiments.
The usb Midi and midi port are now working with this arduino.
i buy them from aliexpress just don’t buy the blue ones with a micro usb because most of the time they use a usb smd part instead of true hole part. because those USB micro things break without any force.
The ones that i recommend are these:
Choose the one with the usb B mini!
Or if you want a pro micro with a tougher usb micro that isn’t just a smd part i some times choose these
