32-Bit Processing For The Vectrex Arcade System

Alongside the Commodores, Ataris, Nintendos, and all the other game systems of the 80s, there was a single unique video game system that stood out from the pack. This was the Vectrex, a console with a built-in CRT meant to display vector graphics and only vector graphics. The video game crash of 1983 wasn’t kind to the Vectrex, but it still lives on with a reasonably popular homebrew scene. Still, these homebrew games are limited by the hardware itself. After thirty years, the Vectrex has an upgrade. The Vectrex32 is a coprocessor, designed for the Vectrex cartridge slot, that gives …read more

Building A Wavetable Synth

Every semester at one of [Bruce Land]’s electronics labs at Cornell, students team up, and pitch a few ideas on what they’d like to build for the final project. Invariably, the students will pick what they think is cool. The only thing we know about [Ian], [Joval] and [Balazs] is that one of them is a synth head. How do we know this? They built a programmable, sequenced, wavetable synthesizer for their final project in ECE4760.

First things first — what’s a wavetable synthesizer? It’s not adding, subtracting, and modulating sine, triangle, and square waves. That, we assume, is the …read more

PIC Mesh, Accessible Distributed Networking

Wireless networks have been reduced to a component, for most of us. We fit a device, maybe an ESP8266 module or similar, and as if by magic a network exists. The underlying technology has been abstracted into the firmware of the device, and we never encounter it directly. This is no bad thing, because using wireless communication without having to worry about its mechanics gives us the freedom to get on with the rest of our work.

It is however interesting once in a while to take a look at the operation of a real wireless network, and [Alex Wong], …read more
