As many of you will know, a computer geek is always working on several things at once. When something becomes boring, the geek moves onto another project, until that becomes boring, et cetera. This page should be a relatively up-to-date list of the things I’m working on at the moment.

1. PolyController

PolyController Main Board

PolyController Main Board

Slightly fed up with our central heating controller and thermostat being so stupid, I thought I could do better myself and build my own. Our current controller is nothing but a time switch, and the thermostat a manual dial one that has unfortunately been mounted right next to the main central heating feed pipes and hence is mostly useless.

This project started out as a simple but powerful replacement for our current heating timer and thermostat, but has grown into a general purpose controller with 1-Wire, ethernet (IPv4 and IPv6), an RTC and an almost endless number of relays attached.

2. Electricity Metering & FrankenUPS

Back Room Overview

My efforts to measure our electricity usage at home and to extend the runtime of my battery backup system for the server, routers and switches.
