I saw an electric lady in a travelling sideshow. The type where she throws sparks from the hands, makes paper burst into flames and causes bulbs to light by holding them. I'm assuming they are using a high frequency power supply (very low amps), and I was wondering if anyone has built one and if there are any good schematics on line?

I needed a 12v battery to powered my RC toy car.

I have this motor that I want to use for an automatic dog feeder project for a local animal shelter. It came from an old record player. It says "100 - 130V" on it, and "8W, 0.14A, and 50-60~". I have to say i'm not very knowledge about electronics etc at all. I really basically just want to be able to plug it into mains and then that it runs slowly, it doesnt matter very much exactly how slow. I have no idea but wonder if wiring it to a plug and then plugging it into a mains socket would be safe and if it would then run like I want it to? I can really only scavenge supplies to make this project work. thank you!

I read the article on how to make a 72v electric bike and a 96v electric bike and i was wondering if we could place another 72v motor inline with the main ( so when 1 motor rotates the othere also rotates at same speed producing electricity )and use the 2nd as a generator to charge the battery . if we could use a diode in the circuit so as to make the current flow from the 2nd motor to battery and not the other way.

I am going to make an electric vehicle so my question is that how to calculate cost per unit,cost per mile for an electric vehicle? and ways to overcome weight issues so that when a person sits on the vehicle, the speed does not reduce or less. I am asking this because i want to make a vehicle that will cover many miles with less battery efficiently. I hope that everyone understands that what i am trying to ask

The head of my electric toothbrush broke and replacement heads cost almost as much as I bought the toothbrush for, so I'm not going to buy a new one. I now have a headless electric toothbrush and wondered what make with it since it seems too nice to just throw away. Unlike most electric toothbrushes, this one doesn't rotate back and forth but instead reciprocates forwards and backwards about 2-3mm. Anyone think of something useful I could make of it? I tried to use it as a metal etcher, but it doesn't move fast enough for that unfortunately.

However, I'm not experienced enough to read a schematic and I can't find any other tutorials that use the same motor. It's from a 2014 Whirlpool Dryer. I need to know where to connect the black, white and green wires. Any help is appreciated.

Electric Average: How do you compensate an electric bill from a previous bill when factoring in a difference in av temps
I understand the averages using billed days, total kWh, and the average kWh per day. But, how would I account for different average temps? I put in LEDs this fall and want to see if there has been a difference in usage. our av. Temp this Feb was 29 degrees; last year it was 34.

For a school project I am building an electric bike and thought it would be fun and an attention grabber if when people were on the stationary electric bike the faster they pedaled the louder a speaker would get. Is that even a possibility? The motor is an 1000 Watt motor on the rear wheel. I think that the higher the voltage or current, the louder a small speaker would get.

How do I know where the pickups need to go. I guess there is some sort of rule about how far apart the pickups should be from each other, and how far from the neck and bridge?
