Ultratroninator 3000. Yes, that is a silly name.

Backplane VCA and Zoxnoxious Bus

Order placed with JLCPCB for a backplane board for this project. My setup so far has been a Raspberry Pi Zero with some breadboard glue for 3.3V/5V level shifting and other janky connections. The backplane board aims to solve for that, and include a legitimate 1/4″ mono/stereo output connection. It’s a decently big board, just…

Hard Sync: Not Hard, Easy

Coming soon: video detailing hard sync on the Zonxoxious 3340. Positive sync, negative sync, phase modulation… cool stuff that I’ve not seen on many 3340 implementation. And phase modulation on exactly zero. It’s something you could do with the right modular equipment, but not in a single module. Some teaser examples here: Sawtooth sync: Triangle:…

[Video] Zoxnoxious Demo

I did a little video demo of the board and the VCV Rack plugin. Hopefully it explains a bit or just gives you a good laugh at my demo skills. More to come, I’m working on a board revision to resolve a few of the issues with the current one. And also include some variation…

Big Picture Vaporware

A ‘3340 oscillator itself is pretty boring, so what am I really up to? I’d like to develop this to a larger platform that could control multiple cards, an oscillator one of them. The ‘3340 board is doing a great job on helping me develop and shape that. So what’s the larger picture look like?…

‘3340 Update. Now with VCV Rack control

I’ve been taking as many shortcuts as a I can developing some sort of analog synthesizer. More specifically, analog audio path. Plenty of digital in the mix. What’s happened since the previous post? Revision 0.2 board received from JLCPCB. Soldered up and testing. Pi Zero configured as USB Audio gadget to drive the board’s DAC…

CEM3340 Oscillator Project

So this post and ones that follow will take a bit of a different turn, not so much on the Ultratroninator 3000 hardware but on other projects. The most recent project I’ve been active with is an audio oscillator, the CEM 3340. The CEM 3340 and its clones (I’m using a Alfa Rpar AS3340 clone)…

[Video] Pong

Yeah, it’s Pong. Why? Mainly ’cause I was redoing some of the underlying libraries and wanted an easy hack to see what new devils I unearthed. So, Pong! I decided to use actual tennis samples for most of the ball hits, and combine that with classic video game sounds for the rest. Gives it a…

[Video] Tempest in a Teacup…or LED Display

So I’m calling the Atari Tempest hack done. Tempest was pretty fun to program. It poked holes in the library I’d written for doing a view. And more obviously it isn’t quite the right game for a 14 segment display. But hey, let’s focus on the positive. The sound effects are cool, being samples taken…

M Control Program

About time I wrote a post about the orchestration piece of the Ultratroninator 3000, the MCP. The MCP, or “M” Control Program (pick whatever term to use for M: Main, Mindcontrol, Monitor, Malicious). Name aside, it’s got a simple job of listing all the hacks available on the Ultratroninator 3000 and launching the game/hack. Pretty…
