I have an old HR flashgun powered by two D cells. It has the Graflex "look" and I like having the flash raised up from the camera. I have a supply of flashbulbs for it that I dip into occasionally, but for many subjects, they are overkill on output.
It occurred to me recently that putting a shorting plug into the shutter connection on the unit would supply constant current to the bulb socket. This would supply me with three volts DC... exactly enough to power a (fill in favorite coloquialism)-rigged Vivitar 252 or 152 flash. I don't think there are any voltage-boosting devices in the flashgun, but it is simple enough to check the voltage with a volt meter. I think I have a 252 around here someplace, I saw it just last month.
I could use a socket plug adapter and a household plug to get power to my flash unit and lots of epoxy to hold it all together. The little flash tube and accompanying electronics should nestle into the 5" polished bowl quite nicely, giving me a perpetual fire M3B/AG1 flashbulb with automatic exposure.
When I want to use flash bulbs, I can simply remove the shorting plug and socket adapter.
Aside from the danger of electrocution due to the capacitor, can anyone come up with a reason I should not proceed?
Thanks. |
