This is an arduino with the Mozzi library and some arcade controls and knobs in an old wine box.
Made it for my 1 year old and he seems to like it, probably mostly for the lights 
Has anybody else built something like this? And suggestions for additions?
I might add a ring of lights around the knobs. And maybe a joystick that lights up.
Specs?
Schematic?
Stripboard layout?
PCB’s available?
This would be freaking awesome to get the kids that I teach at yoyo club into synths!!! 
Haha I could look into making a PCB if anybody really wants one. Made this on strip board. Here are my sketches:
It uses a arduino pro micro with two 74HC165 ICs for the buttons and a 74HC595 for the LEDs. The pots connect directly to the arduino.
Here is a pic of the breadboard layout.
nice and good idea to make a little synth for your son
i have made some stuff who could be cool for chidren but not like this with arduino
Just seen this. Well done. As for suggestions take a look a capacitive or resistive touch or some of the soft / fabric controllers (as you already have an arduino in place) . Tilt, piezo and breath controllers too. Drones, a LDR theremin, springs, pressure pads (easy DIY). I love am array of old mercury switches (maybe not for a 1 year old unless you encased them in clay) .
Fantastic stuff. Hope to see more.
That’s super great! I’ll have to look into some of that stuff as I do t what it is haha!
Happy to explain any or all. Have fun. Would love to see a video of your synth in action.
Added a battery so we can move it around and he doesn’t play with the cords
But a broke the box cutting out the panel, hot glued it back together
Much better than the casio vl tone I grew up with. And still need to repair.
