Also, 'every 10 hours' doesn't divide well into 24 hours, but he'd be probably happy with every 8 or 12 hours. Hmmm, you'd need 48 pegs to do 5 minutes on/off every hour. First Google for 'timer pegs' - http://www.kalyx.com/store/proddetail.cfm/ItemID/56969.0/CategoryID/12000.0/SubCatID/2845.0/file.htm - ouch, $US1.12 a pair! As Jinx suggested, use one for the parts. Timers are $7, pegs are $1 a set. I think I'm being screwed here...!
