I need advice on how to make a capacitor charger. I know somebody is going to say camera charging circuit but i have one and it doesnt make the cut. I am planning on getting some transformers from wall bugs and old alarm clocks. but i need to know how to wire them and make them work with a DC input and an AC output. I need it to be at least 500 volts output

Any ideas how one could transform rotational movement into usable energy? I want to attach a little radio device to a tire and have that device charge a little battery when the wheel rotates so that it can transmit information (i.e. rpm). Was thinking of using a small Nordic radio and accelerometers to transmit data.

I have three Black and Decker, 18volt battery chargers, for the FireStorm series tools. One is an orange dual charger. One is the single black charger that came with the drill. And one is the Radio charger. The radio charger AC adapter case melted and no longer works. The single and double chargers both seem to kill batteries, and do not charge. I have voltage coming from the chargers, but I don't remember how much. Does anyone know what the voltage should be on the charger? More importantly, how do I repair the charger to output the correct voltage/current?

Hello I want to charge my sony ericsson w580i with my iphone charger. My SE charger is rated for charging at the current 4,9V but my iphone charger outputs 5,25V. Is it harmful for the battery in my SE mobile to have a 0,26V current extra? Or can i put in a resistor between to lower the current from 5,25 to 4,9. Old charger: 4,9V , 700mA Iphone charger: 5,25V, 1A.

I want to make a solar charger to charge AA's for my camera, my phone ( LG Banter), ipod touch, and maybe a DS Lite. And if somehow I could detach everything except for the batteries for when I backpack.I have pretty much no knowledge on curcits, but I do want this to be a fast charger for the AA's. I was thinking of ordering and making a high-speed charger and making a mini-boost. But I'd like to spend less than $50 on this entire project. Any help is greatly accepted.

I now have 2 Toshiba laptops, a Portege M300 and a Portege M600. My M600 is secondhand, and didn't come with a charger, however i discovered that the charger port is smaller than the charger port on the M300. Will i have to buy a new charger or is there anything i can do? new Toshiba chargers are, I believe, AUD$96.
