Backpack Generator
Intro: Backpack Generator
Have you ever felt your Backpack shake too much and wanted to do something about it?Well now you can charge your phone by all those shakes!
STEP 1: Parts
The required parts are-
1. Magnet wire
2. Plastic tubing and caps
3. Foam
4. USB power cable to device
5. Wire
6. 5 diodes
7. Magnets
1. Magnet wire
2. Plastic tubing and caps
3. Foam
4. USB power cable to device
5. Wire
6. 5 diodes
7. Magnets
STEP 2: Coil
On the plastic tubing attach a piece of foam,and then start coiling the magnet wire.Remember to coil in only one direction,after coiling a length of 3-4 cm bring the wire back to he start and continue coiling. Do not coil backwards.Coil to a depth of 1 cm. Depending on your choice make 2-3 coils.Attach foam on both sides of the magnet.Place the magnet in the coil tube and seal the tube so that the magnet does not come out.
STEP 3: Charger Link
Now cut the charger wire and skin the 2 wires inside.The red wire is positive while the black/white is negative.
STEP 4: Rectifier
To make the rectifier follow the schematic. Preferably solder the diodes to make the connection.
STEP 5: Connections
Test the polarity of the coils using a voltmeter.Now connect the coils such that the positive terminal of the first connects with the negative terminal of the second and etc.Attach the starting and end terminals to the rectifier as shown. Take the output wires of the rectifier and connect it charger.
STEP 6: Enjoy!!
Enjoy showing off with the new backpack.Be the new tech advanced kid in school. Charge your iPod just by shaking your bag!!

I think this can also be used for movement generator. Think about wearing shoes and bracelets with these kind of generators to power up accumulator/power bank stored in your backpack so that even when you move (walk, run, etc) you're producing energy which can be used at later times. What do you think :)

Do you have any specifics on the kind of Diodes and the kind of Capacitor.

You should break this down into more steps with more photos and include a slightly more detailed description please.

I wonder whether using springe (from one ot both ends of the tube to hold the magnet) would improve performance, since the magnet would always be close to the coils. The question is, would the gained energy harvested from smaller shakes be worth what the springs would cost, energy-wise?
