Graham... I did a search on google for high speed photography and came up with a bunch of sites that may help.
2 of the most promising seem to be: http://www.hiviz.com/ http://www.woodselec.com/HowTo.htm (I couldn't get this one to load) Hiviz had all sorts of do-it-yourself timing circuits etc. Popular mechanics had an article on stroboscopic photography years back. It had a homemade plywood wheel mounted on a motor. The plywood had slits cut into it and would spin in front of the lens. The subject was lit. and the shutter was pressed at the appropriate time using a long shutter speed (1-2 seconds). I don't think it needed a light tight box, but don't remember all the details Hope this helps some.
