that's what i thought. i am really impressed with these ghetto flashers, and still want to know if these home made thingies actually worked at some time. presumably they did?Impressive ingenuity!
i assume that either pennies were really tight, or parts availability was a problem - not such an ususual scenario if this machine came from the backwoods of some backwoods country somewhere in Eastern EuropeWhy they couldn't just buy flasher lamps is beyond me!
