Got quite a few hobbies really..
Retro Gaming (Consoles mainly, but ZX Spectrum and Dragon 32/64 in there too
I'm currently working my way into Mechanics (fixing up own vehicles etc)
Also learning FPGA programming
Motorbikes in general... Riding an old Honda H100S-II at the moment, but currently fixing up a Yamaha Diversion, will probably start fixing up my mates old Suzuki TL1000 after that.
Also I read Discworld novels to pass boring moments.
Also into more modern gaming... Got a PS3, largely for some games that aren't even out yet, but are coming.
Umm.. Application design is another hobby, largely for windows and linux though....
Also.. of course... gadget collecting and using... New and old, as long as they're fun
