Wireless Power





Introduction: Wireless Power

Haven't you always wanted to charge your cell phone or mp3 by just putting down on your desk. Well one company named Splashpower has created a device that can do that.

It works by using electromagnetic induction. Pretty much only Faraday's Law but with an electromagnet. Also this technique is used in charging high-end toothbrushes and Splashpower Devices.

Step 1: Get the Materials

You are going to need these things:

1. Lots of wire. I used 18 guage wire.

2. A piece of steel that your going to wrap wire around.

3. A capacitor, one with high capacitance.

4. A diode.

5. Batteries, I used 6 nine volts.

6. A multimeter so you can see if everything works.

7. And something to make it a little easier, Alligator clips.

Step 2: Making the Coils

To make the Base Coil you wrap wire around the steel piece. I duct taped paper plates to the steel piece to make it easier. The more the coils the better the transfer of electricity.

Then, to make the Reciever Coil I put the non-sticky side on a D Battery and then wraped the wire on the sticky side. Make sure the reciever coil is around the size of the unless the steel piece is huge. Or if you have magnet film to see the where greatest amout of magnetism is. Once you are done winding the coil you can slide the coil off the battery.

Step 3: Putting the Experiment Together

First connect the Multimeter to the capacitor and on 1 side of the multimeter and the Capacitor put the whit side of the diode. Then, connect the other side of the diode(black side) to the Reciever Coil. If you dont use a diode the electricity would flow back into the Reciever Coil. Next, put the Reciever Coil onto the Base Coil.

Then, connect the positive side of the batteries to either side of the Base Coil. Finally, tap the negative side or use a momentary switch so the electricity switches on and off. I tried using a motor but for some reason it doesn't work, if any one knows why comment. If you continue to tap the electricity and make sure everything is connected the voltage on the multimeter should got up. I got .189 within a second.

Also, watch out you can get shocked.

If you have any other problems look at the main picture and comment.

Step 4: Resonant Charging

There has been talk on the news about a new way to charge wirelessly. Resonant Charging. There is no comercial devices to do this and I am think of homemade ways to do this.

If you have any ideas comment me or send a message.

    i have no idea why i think it may work but if you used a strong magnet or electro magnet instead of just steel with copper wiring round it would it be more "wireless"

    That is a cool project. I'm wondering how we can get the efficiency up (aren't we all).

    have you ever herd of Tesla he transmitted wireless electricity 10 miles with 99.99% efficiency, over 100 years ago thats better than wires today

    Wrong! It was majorly inefficient and there were many drawbacks but yes he did do it along time ago! (He also knocked out what was the then power grid several times before he got it right. And the proof of concept was that he light up rows upon rows of light bulbs that weren't connected to anything at all!)

    1. He WANTED to do that. Power died before he could test that theory 2. His theory was wrong 3. He used a more dangerous approach thats been around for.... ever. It is dangerous to humans due to the using RADIO waves instead of microwaves. Thomas Edison did a little work in this area as well. Not to be mean... but keep facts straight before blearting them out... remember that your expecting people to believe you.

    umm Radio waves and Microwaves are the same thing.....
    Tesla invented radio and modern AC Technology that we use in our houses today.

    Read the Wiki article http://en.wikipedia.org/wiki/Nikola_tesla

    "...keep facts straight before blearting them out... remember that your expecting people to believe you." Ditto....

    oooooooooh your right. (why do people think marconi invented radio? he used15 of teslas patents and tesla did radio way before him.) oddly I have the same first name. KJ6CJH :) nice instructable.:)

    Marconi invented the radio for sound transmission.

    Marconi did not invent the radio. That would be Tesla. 6 months after his death, the supreme court invalidated Marconi's patents and awarded them to Tesla, because of his work predating Marconi's.

    I don't see Tesla anywhere on Washington State's page, http://public.wsu.edu/~bryan.mclaughlin/Radio/Who_Invented_Radio.html
