OK, I know I've seen a company advertising that they will convert your old flashbulb flash to an electronic flash, but I can't find them anywhere now. Or anyone have any info on converting a flashbulb to electronic flash? I have a couple of Rolleiflash units that I want to change for use with another project. Would like to get a nice variable power thyrister type built, nicer would be to have a photo sensor for "automatic" exposure. Of course it must look as close to stock as possible which means I will probably have to go with some kind of advance battery technology, probably Lipoly since they are small, powerful, and easily obtained. Anyone able to point me to some guides that might get me started? Working on electronics is not a problem, so if I have to make major changes I should be able to get them done.
