What IC chip back from the 30's was able to increment time from the 60hz i'm intrigued by this, timing from the hertz cycle of the power supply I always assumed they all had some kind of crystal / oscillation routine...
how's the circuit detect the hert rate? any ideas and would be as simple as modifying the circuit to trick it into going faster.. something new :O
Back in ye olden days of yore, electric clocks used a mysterious contrivance called a "motor." This "motor" turned at a rate very precisely proportional to the line frequency. (Lots of AC motors do that. It's a motor thing.) To get the "hands" (clocks had "hands" back then, instead of LEDs or LCDs or plasma displays) to turn at the appropriate ratios, they used a complex mechanical arrangement called "gears."hso what on earth do you have in a 1930's clock?...
There are voltage booster circuits on the web but many of them are too complicated for this application.Your high voltage ic is ideal but unfortunatly out of reach for me, do you have any further suggestions or is there an altrnative to that ic?
Not really, unless very high output current is needed. In fact it is more difficult to make it works than the transistor version because of the MOSFET gate capacitance.Would the mosfet version have any advantage over using npn/pnp transistors in the output?
