ApOPL3xy Emulator
Last week, I posted about the ApOPL3xy reaching the version 1.0 milestone. This time, I want to discuss the emulator I wrote for it. I think it’s pretty cool. The emulator was initially conceived as a way to run the code on a computer with all the debugging tools that I’m used to having at…

ApOPL3xy 1.0
It’s been a long journey, but I finally have the ApOPL3xy hardware and software to the point where I can call it version 1.0.

I’ve made and posted a new version of Damon: The Rocket Jockey which adds an updated music track.

Damon: The Rocket Jockey
About two months ago, I received in the mail my very own Commander X16 computer. This is a modern 8-bit computer envisioned and produced by David Murray (a.k.a The 8-Bit Guy) along with a thriving community. It’s inspired by Commodore computers from the 1980’s, primarily the Commodore 64. I hooked it up and started playing…

ApOPL3xy Hardware Design
I’ve been working on designing and building a MIDI synthesizer (called the ApOPL3xy) based on the OPL3 FM synthesis chip and the ATmega1284 microcontroller. I’ve made a couple of posts about it (here and here) and have gotten some good questions from some people about how this or that works under the hood. So, for…

ApOPL3xy Update – Patches, Omni Mode, and Percussion
I’ve added some new features to the ApOPL3xy synthesizer project I talked about in my last post. Some technical details follow, but first, let’s check out what the new version can do. Specifically, MIDI files can now be played from a computer (or other sequencer) into the ApOPL3xy to be synthesized. […]

ApOPL3xy – A MIDI OPL3-Based FM Synthesizer
It’s been a while since I’ve posted anything about electronics projects. I have not been idle, however. My current project is finally starting to come together enough to be able to show it off a little. It’s a MIDI synthesizer powered by the Yamaha YMF-262 (a.k.a. OPL3) FM synth chip […]

Tetris Theme
When working on projects, I often let my mind stray toward future goals instead of staying focused on the immediate ones. Case in point: I started thinking about making a Tetris clone for my 6502 computer (once it has a video display). Naturally it would need music as well, since I’ve hooked up an OPL2…

Homebrew 6502-Based Computer
I’ve been toying with the idea of building a 6502-based (or rather, 65C02-based) computer for a few years now. I was inspired by Ben Eater‘s YouTube series about it. I bought a bunch of chips from Mouser, and every so often I’d think about how to do this or that for the notional computer. Well,…
