Hi again. I am still unsure whether you want to build strobes or what. If you have good electronic construction skills you could put something together which would suit your needs. Basically, any strobe consists of three parts -- a source of high voltage (200 to 300 vdc), a flash tube with trigger circuitry, and a pulse generator to drive the trigger at a flash rate of interest. Running the system from 12 vdc would require an inverter to generate the high voltage, otherwise operation would be the same as for an AC operated unit. It is probably most economical to cannibalize an old battery-operated photoflash which would provide just about all the items required. The circuit would require replacing the original storage capacitor with one of lesser capacity, and hooking up a simple neon/capacitor relaxation oscillator to drive an SCR which would, in turn, trigger the flashtube ignition coil.
If all this is a bit intimidating for you, you may wish to investigate some of the Strobe Kits which have all the parts required for home assembly. Herbach & Rademan (www.herbach.com) show some models, and even some completed assemblies. Look for Kit#TM90 OPT1152 for the kit, Cat# T7-101 for complete assemblies, and Cat# TM920PT2009 for complete camera photoflashes if this is the route you want to take. There is also a Strobe Kit listed at All Electronics Corp (www.allelectronics.com) Cat# Strobe-1. All these items are in the $10 range except the photoflash which is $3.50. Both these companies have catalogues available on-line.
I can provide further technical advice if required, but really need you to decide how far you wish to go.
