Tactile Button Keyboard PCB

I've used tactile buttons as musical keyboards in a number of my projects now and either build them on solderless breadboard, which is quite unreliable, or on stripboard, which is a little messy. This PCB design is for a one-octave tactile button keyboard PCB that has various modes of operation and is extendable to two …

Toy Keyboard Tone Piano – Part 5

In this part of my series on adding an Arduino to a toy keyboard, I've taken a second keyboard and actually embedded the Nano inside it to make it a complete DIY Oskitone Scout, powered by USB.  This is using the version of the hardware and code described in part 2 - i.e. without the …

Toy Keyboard Tone Piano – Part 4

I'm continuing my series of posts seeing what I can do with a toy keyboard.  This post looks at some possible uses of the additional IO pins I freed up in part 3. Part 1 provides all the details for adding an Arduino to the original toy keyboard. Part 2 demonstrates the toy keyboard running …

Toy Keyboard Tone Piano – Part 3

This post looks in a little more detail at the keyboard matrix decoding for the toy keyboard to see what is possible with less IO pins. Part 1 provides all the details for adding an Arduino to the original toy keyboard. Part 2 demonstrates the toy keyboard running the Oskitone "Scout" firmware. Warning! I strongly …

Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2

Having added USB MIDI to my "Toy Keyboard" - I wanted the option to choose either USB or serial MIDI as the output.  This returns to the Toy Keyboard USB Matrix Decode with the Pi Pico project to add a serial port option. Warning! I strongly recommend using old or second hand equipment for your experiments.  …

Toy Keyboard USB Matrix Decode with the Pi Pico

I never really got back to looking at my "Toy Keyboard" - I wanted to do the same as the Vintage Phone - create a USB MIDI version with Circuitpython.  Well now I have.  Here is the result. https://youtu.be/VNmp3-mwysI Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not …

Toy Keyboard Matrix Decode with the Pi Pico

I'm always on the look out for discarded music keyboards that I might be able to do something with, so when I came across this thrown out in the street I claimed it to take a look. This shows how I used a Raspberry Pi Pico to decode the keyboard part and turn it into …

Vintage Phone USB MIDI Controller

This is the USB MIDI controller version of the Vintage Phone MIDI Controller.  As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for …
