Dont worry about the youtube channel. Every single comment helps increase the value of that video. I do not like converting any strange motors. Ceiling fan motors work very well if you add magnets in them too. I have not done it yet, but plan to do so one day soon. I also have a HUGE fan motor, but ...

By the way, I was thing of making a VWAT one day. Lets see if I can get some time this spring for it.

If you can take apart the motor and pull out the center rotor. If the rotor is a solid cylinder of metal. Then you can drill/cut slots for the magnets. Put it together and you have a windmill. I have the magnets and a good old box fan motor waiting for me to get some time to machine it into a very n...

Ok, your video shows me why you are getting AC. It is a DC motor, but you are spinning it back and forth. One way gives a pulse in one direction. When you reverse the direction, you are reversing the voltage. Try to spin it up in a hand drill in a single direction and you will see DC voltage. These ...

The rim size is not as important as how freely the bearings spin. The wheel should spin freely for about five minutes after you give it a good solid push. You can loosen the bearings a bit by loosening the pressure on the nuts holding them together just a little. Magnet quantity is also flexible. Ju...

There is no easy answer to your question, but I will try to help out. It depends on the size of the coils you use. I first hooked them up in parallel. Then I used a separate transistor for each coil later on. This gave me two power coils with full circuits and one trigger coil. I think they would al...

Can you open them? Or can you look at the armature inside somehow? DC motors will have solid magnets inside. AC motors will have an aluminum armature inside. 4 wires could also be a DC stepper motor. The best way to tell is by reading the label on the motor or looking for magnets. Also most AC motor...

Here is a schematic for the homemade solar charger.

You can use dollar store solar path lights to make a solar battery charger for AA or AAA batteries with no other parts needed except for a singe diode. Take four solar path lights and remove the base stems. These you can use as garden stakes or for another project. Twist off the tube shapes lense pi...

I think maybe your desk lamp is too dim to turn off the circuit. On these solar path lights, the sun shining on the solar panel turns off the LED light circuit and allows the batteries to be charged. If the sun (lamp) is dim, the circuit lights the LED. Try this outdoors and see if your LED is still...
