I've just realised that I never finish anything that I do in my spare time. I tend to keep getting distracted by new and exciting projects so everything sits about 80% complete:
Home automation via bluetooth: I wrote a jabber bot which interfaced with my Ericsson phone and added an accessories menu letting me do things like set the heating, lighting, and so on. But it doesn't auto detect the phone coming into and out of the house, or pass on SMS messages, or do anything cunning with images.
Put the TiVo in another room:
I built a test circuit to pass composite video over CAT5 which works really well - the idea is use it to distribute RGB from the TiVo (by having 4 such circuits) which means I can bung it out of the way.
Java fun: I just bought a T610 phone and started playing with Java on it so I can do cunning things like view the cameras outside my house remotely from anywhere.
GTK: A jabber bot for the home automation system that pops up little animated transparant pictures of the people that call the house. It kind of works, but doing animation and changing the mask causes flickers.
Spare time over the last few weeks has been a bit limited what with the OpenSSH and Sendmail issues, and I guess I need to finish off my talk for ApacheCon.
