Programming music directly into an FPGA can feel like a grind—especially if you’re hand-coding note tables and timing values. When working with the Digilent Nexys A7 (100 MHz), I wanted a more direct way to take melodies I’d written and…
Fully FDM 3D Printable Game Battlefront Valkyrie is a fully 3D printable tabletop starship game created by Tom Tullis over at Fat Dragon Games. Finally! I’ve been looking for a 3D-printable game that I could print the models on my…
Introduction In this tutorial, we’ll build a real-time color monitoring system: Hardware: APDS-9960 color sensor connected to a CircuitPython-capable board. CircuitPython: Script to connect to Wi-Fi, read RGB values, and publish JSON payloads to the sensors/color MQTT topic. macOS SwiftUI…
Turning a MIDI File into Arduino Music with PlatformIO 🎵 Project Overview In this project, we created a simple workflow to convert a standard .mid MIDI file into binary note data suitable for playback on an Arduino Mega 2560 using…
I’ve spent the past few days exploring a project that allows me to display text on an LCD using a Raspberry Pi. We will be using Python in this post, so familiarity with Python will be useful. First, make sure…
My retro computer is an SC126 designed by Stephen C. Cousins. It has two serial ports. I am using 1 serial port to interface with my retro amber monitor. That leaves the second one open to use as a way…
I once owned a Roland JV-1010 sound module. I bought it in 1999 to go along with my FP-9 Stage Piano (which I still use in my home studio). I really loved the sounds on the JV-1010, so last year,…
I’ve been having difficulty getting my Mac connected to a wireless printer. No matter how I configured it, it would always enter paused mode whenever I printed a document. It turns out that all I had to do was connect…
About seven or eight years ago, I started down a path to create my own synthesizer using discrete electronic parts like CMOS chips, resistors, capacitors, and the like. Early on, I discovered the “Lunetta” synthesizer, made from 40106 CMOS chips….
I am a big fan of retro homebrew computers. I have a few kits that I ordered from Tindie.com based on the RC2014 model (SC126). To keep it completely retro, I bought a classic amber terminal so I could have…
