Learn how to build a custom Arduino MEGA MIDI Man-in-the-Middle (MITM) device that inverts incoming notes, letting you play any standard keyboard as a perfectly mirrored “left-handed” piano.
Implementing a digital delay on an FPGA using Verilog
Exploring the use of FPGAs as audio processors (reverb, delay, etc.)
To understand how hardware and software commingle to create a functional computer, we will analyze the Retro180Emulator, a project designed to emulate the Zilog Z180 microprocessor architecture on macOS.
I recently built a weather display for my Adafruit PyPortal Titano using CircuitPython. This project fetches live weather data from OpenWeatherMap and displays the current temperature, condition, and details like “feels like” temperature and wind. In this blog entry, I’ll…
Over the past few days I’ve been working on a fun FPGA project: getting a sprite (my little ship) to move around the screen on a Nexys A7 board, complete with a starfield background, rotation, and even thruster sounds when…
Over the last few weeks I’ve been implementing a minimalist 8-bit SAP-1 (Simple As Possible) computer on an FPGA. This post captures the architecture, the SystemVerilog snippets that make it tick, the VGA output I just added, and the little…
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…
Writing C programs for speech on the SC126 (RC2014 Compatible) with a SPO256-AL2 Speech Synthesis Chip I spent some time yesterday working with ChatGPT to assist me in writing a moderately complex (based on my personal experience) C program. The…
I recently spent some time with my digital audio workstation (DAW) putting together a heavily delayed feedback loop on the audio channels. I split the audio and sent it to the input of the effect, then took the output of…
