Using Teensy 3.6 to read in the shift register from a SNES controller and convert it to a USB gamepad.
Retro gaming done right!
Edit: I don’t know if that’s actually a Motorola chip. I read that somewhere and it does have an M on it but it doesn’t look like the correct logo.

I needed a way to keep time while "playing" "music", and it wasn't practical to use an audible metronome so I soldered up a 555 timer and 4017 LED chaser and configured it as a visual metronome.
It kept time but I don't know if I did.

When piezo transducers are mechanically struck, they generate voltage spikes that can vary in voltage level, polarity, and active duration. The voltages can be a few volts or many tens of volts.
This pcb provides an interface between piezo elements and a microcontroller input (analog or digital). It limits the voltages to safe levels, filters them, and provides a more consistent level-sensitive output as the device is struck with varying intensity.
This pcb provides a 4 channel signal conditioner, allowing piezo elements to be used in a drum sample player on Teensy 4.1

The X9C series of digital potentiometers feature a simple 3 wire control interface, provide 100 steps of wiper adjustment, and can optionally save the wiper position for automatic recall of the setting after power on.
Here's an Arduino Uno sketch showing how easy it is to control and use the X9C family of digital pots.
This is a follow up to two previous videos:
