In this video, you'll learn how to "MacGyver" a 40 Watt Electrical Generator from a cordless drill and a few household items.  Here's how to charge a phone, illuminate small lights, and make electricity in a pinch.

Step 1: Watch the Video!



Note: This project is intended to be a "bare-bones" approach to generating electricity in a tight situation.  There are no voltage regulators, no diodes and no capacitors to smooth the current.  There may a risk of overheating and damaging equipment when operating electrical devices without a proper circuit recommended by the manufacturer. 

It worked fine for me, but if you try this on your phone make sure you understand, and are comfortable with, the risks.  Back up your data in case your phone is adversely affected and your data or equipment is damaged as a result.

Step 2: Household Items

There's no charge for this electricity! All you'll need for this project is...

1. A cordless drill
2. Anything you can find to help secure it in place and spin it by hand.

I used;

* A piece of wood 2"x4"
* Some yarn
* 1 mixing beater
* 1 salad fork
* A piece of aluminum foil
* Some Scotch tape

Step 3: One More Thing You'll Need

You'll need a way to connect the power you generate to your phone.

Look for an old phone charger you might have, and cut it in half.  We just need the piece that plugs into the phone.  You could even use a USB charger cable like the one I found.  

Inside the cable you should see 4 wires.  White, Green, Red and Black.  The Red and Black ones are the only ones we'll need for this project.

Note: For this project I used an old Blackberry Pearl.  If you are using a smart phone, the white and green wires may need to be shorted out or connected to a "dummy load" to get a successful result.  (I haven't tested this method yet but have had feedback from other viewers suggesting this is the case)

Please note that if the selected drill has any form of "electronic speed control", it will require more dis-assembly than merely removing the battery as such electronics will probably impede the original intent of this project.

I also suggest connecting your USB wires directly to the battery contacts (or internal equivalent). The use of "foil" introduces more problems than it solves.

Was this just an experiment, or did you really need to charge your phone manually?
Now I have a use for my broken Black and Decker!
Perfect!! :)
Fantastic idea!
Glad you like it Dave!
I gotta say, the thing that TOTALLY brought me to the tutorial, was your name, "The King of Random".
That's very cool.
But yes... this instructable is great!
Haha I'm glad to hear that. It's a name given to me by a friend who was always impressed by the random projects. I'm glad you like them as well!

Fabulous as always! I've learned so much from your videos. I had a magnifying head lamp set where the bulb broke, and we couldn't find a replacement, but I bought a cheap led night light and replaced the bulb that way. I know, not a big deal, but it was the first time I "hacked" one thing to use for another and also the first time I was actually RIGHT when I told the hubby that it would work :o) Thanks for that!
