Mainly RC - helis (4 flying, 1 not), gliders (4 flying, 3 in progress), and recently cars (1 riding, 2 in progress).

Computers... most things unix and internet architecture related which often brings programming into the mix. Started out as a hobby, but now mostly my living.

Recently started messing with CAD and VERY tempted to delve into machining... need more money+time!

A bit of an audio junkie, but that has been dormant for some time now (probably due to RC!)

A bit of dabbling in electronics now and then... thinking of focusing on it with more professional intentions...

Most important hobby - searching for a way to make a lot of money doing no work at all. :D
