Building a Breadboard Synthesizer With a Raspberry Pi and an Arduino Uno

Build a Breadboard Synthesizer (Raspberry Pi Synthesizer) Hero

There’s a lazy stereotype about middle-aged men that says that all we want to do is tinker with our gadgets. I’m doing very little to challenge it, which I guess is how I came to weather the pandemic by trying to build my own Raspberry Pi synthesizer.  Building a breadboard synthesizer is a fun project […]

Raspberry Pi Unifi Controller Setup

The Best GPIO Tutorial for Raspberry Pi that We Could Write

The Best GPIO Tutorial

You can do a lot with a Raspberry Pi even if you limit yourself to what comes on the board. But if you’re willing and able to learn how to use the Pi’s general-purpose input/output pins — or GPIO pins, for short — then you’ll be able to do so much more. If you’re new […]

RetroPie PS4 Controller Guide for the Raspberry Pi

RetroPie PS4 Controller Guide

You can set up a RetroPie on the cheap with just about any USB controller, including super-cheap options like these ones. But just because you can doesn’t mean that you should!
