	Hello. I was wondering if it would be possible to create a circuit which switches on and off every 10 seconds. It is to act as an automatic switch for a kite camera.

	A capacitor and two electromagnetic relays are all that are required. Electronics make circuits more sophisticated, more repeatable, etc., etc. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	I have managed to do it by putting one 0.1 microfarad capacitor across the shutter release wires and it takes a picture every 10 seconds.

	Wow. 24 minutes between the first post and the solution, 8 minutes bw PWSlack's response and the solution. Amazing, the power of CR4 ! __________________ Nothing worthwhile can ever be taught, it can only be learnt.

	Why make one when you can buy it from either Maplins or Radio Shack. works on a 9volt battery and adjustable timing from 0.5 sec to 20 seconds if memory serves we correct.. and is about 30mm by 20mm I got one from Maplins years ago.... google them!! __________________ The square root of nothing is what you make it!
