exSID USB

exSID USB is a MOS Technology SID hardware playback device that connects to modern computers via USB. The goal of this project is to enable accurate, true to the original hardware playback of SID music (such as what can be found in the High Voltage SID Collection) in a convenient, 21st-century compatible way: without a working C64. Needless to say, it sounds fantastic: it will exSID your expectations! :)

rWCHC heating controller

rWCHC is a project aimed at implementing a versatile weather-compensated central heating controller. The goal is to provide smart, accurate and optimal temperature control based on outdoor temperature variations, building structure and occupant habits, in order to maximize comfort and reduce power usage (minimize both the impact on the environment and the energy bill). The system is designed to be scalable and remote operable (via internet connection).

Nixie Clock-o-Meter

The Nixie Clock-o-Meter is pretty much what the name implies: it’s a clock, first and foremost, that uses Nixie tubes to display information. It’s also a thermometer, and a hygrometer. It comes with a couple bells and whistles as it is, and aims at being a cost effective design (save for the cost of the tubes themselves, of course). And oh, did I mention just how cool it looks? :)

SQ80-M Conversion Kit

Thanks to the hard work of Rainer Buchty it’s now a known fact that there once was a plan at Ensoniq to make a rack-mount version of their famous SQ80. And as it turns out, prototypes based on the ESQ-M hardware were made, and one of these prototypes was reverse-engineered by Rainer, leading to an actual recipe to build an SQ80-M from an ESQ-M.

Thanks to the very detailed explanations provided by Rainer, and after a bit of experimentation, I came out with a simple solution to convert an ESQ-M into an SQ80-M in a relatively easy, non-destructive and reversible way, which I’m introducing here.

JAMMA SuperGun Adapter

For fun and because I needed one, I set out to build a JAMMA SuperGun. (It’s not a weapon, by the way. It’s an adapter for arcade games ;P). There are some guides on the web to do so, but factual information is scarse and none of the designs I’ve seen matched what I wanted. So here’s my little contribution to the world of SuperGuns.

LSDJ MIDI Converter PCB

LSDJ-MC is a design from firestARTer that makes LittleSoundDJ, a Game Boy music software, MIDI capable. More information about it can be found on the author’s website.

This webpage describes the PCB I designed (”LSDJ-MC2+”) based on the author’s schematic (with some minor differences), and provides an assembly guide.

MinuteMaid prog timer

MinuteMaid is a simple programmable timer to control a mains-voltage appliance, with direct power supply (it powers itself from the mains without using a transformer). I couldn’t find exactly what I wanted so here’s a workable solution to this problem. It’s all documented after the usual:

rPi Ctrl GPIO interface

rPi Ctrl is a small interface board for the Raspberry Pi that makes it possible to control appliances through the GPIOs of the Pi. I document here what I came up with, for others to use and abuse. Enjoy! It’s all documented after the usual:
