Getting more power from a quartz clock movement Answered
Using a transistor to boost the output from a quartz clock to drive a larger motor in steps. Is the idea sound what would I need?
Having read a couple of instructables on equitorial drives, I found myself wondering why you couldn't just use a quartz clock movement to drive one? They don't produce much torque is the answer to that one.
Why not? I took one appart to find out.
The gear chain is very flimsy moulded polyethylene, or maybe nylon. the power comes from a tiny armature that makes 1 turn a second in 2 pulses the magnetic pulses are provided by a little cuircit board with the quartz ossilator on it. Here endeth my actual knowledge.
My knowledge of electronics is minimal give me a good set of instructions and I can build it (unless its a joule thief but thats a different matter) but don't ask me how it works. My limited understanding of a transistor is if you put a small current or voltage across 2 pins you can get a bigger current or voltage to flow across one of them and the third, something like a relay.
I was thinking if I took the out put from the quartz cuircuit that provides the magnetic pulses and used it to trigger a transistor to pulse a higher voltage and current through a small 3 pole motor kicking it around 1 pole per pulse.
The motor I have a salvaged and rebuilt in an earlier instructable runs on 3V and draws 0.2A when not under load. the largest motor I have to hand is a big 7 pole one designed to power model planes or cars draws up to 15A on 7.2V the timer cuircuit for that one needed 3 Mosfet's in parralle so I'm guessing thats not possible.
