Not just nights and certainly nothing that's likely to do anything for my sanity.

Learn some Java and Javascript of which I've pretty well forgotten anything I might have known, try to improve on my limited php5 and mysql5 knowledge.

A review of folkinfo/annexe coding, features, etc.

Try to write a wysywig editor, probably "borrowing" a few ideas from whizzywig but more tailored to suit my own needs.

Do some LED lights for the garden.

Try to get to grips with some X10 Home Automation and microcontoller related stuff. Probably including attempting to write some of my own X10 software, having a RS485 network... I'll probably end up ripping all my hair out before giving up!

Try to enforce myself to play banjo or mandolin for an hour each day (I love playing in sessions but hate playing on my own and practicing) and see if I can manage to progress a little.

Think that's about it.
