Jinx I would suggest you go down to your local photographic shop which has an in house D&P service, and ask for a disposable camera with a flash in it, that they have developed the film from. This will give you a complete flash unit with the sort of light output you are seeking, and a cycle time that would suitable. Something to remember about these flash tubes is that if not used for some time they will go "soft" and not work properly. This is typified by seeing the trigger pulse arc along the outside of the tube from the trigger electrode, but the main flash does not occur. This problem only tends to occur in units put away in storage for some time. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
