Or a timer set a little longer than the time it takes his door to fully open or close. That timer could shut off the motor power. I have done these things with microprocessors and MOSFETs.

I don't see any specifications on that 529T module. It looks like it still needs the cars window roll module. Also not listed is the current draw in standby mode which would be important if your...

The printer companys give the printers away so they can rape you buying the ink. When I had one I also had the problem of the ink drying out if not used every day. My black and white laser printer...

I really like the idea of building a generator. I don't think this current design will produce much power but that's the fun of it. When he get's it working, I think each coil will need a core to...

Ok your coils are wired in series but each one is reversed winding direction. I'm guessing what is happening is your getting reversed voltage generated on every other coil. Since the coils are in...

Sorry my question on the coils. I re-read your first post and see you have 8 coils. Did you by any chance wire those 8 coils in parallel? That would probably cause you to read 0 volts.

It's common for bedroom outlets to share one circuit (probably 15 amp). So using space heaters on that circuit would be limited. It would make me nervous to put one on a carpeted floor.

It is much better to switch the AC to your power supply since the current of the AC would be much lower than switching the DC current. If you insist on switching the DC current, make sure the unit...

The far left labeled power (black and white) is your power cord that plugs into the wall socket. The load is switched with a relay in the TSU and drives an AC outlet you have wired. So the TSU...

Looks like that first one should work and it has a lot of good reviews. My guess is you wire a normal 120 VAC plug to it and it has a relay that drives the load. Can't be sure until you see the...
