How make your own battery-powered gadget chargers

With a few AA batteries and a $ 5 party, anyone can improvise a charger emergency mobile phone. Here's how, and how to expand their construction skills for working boot-in digital cameras, computers laptops and even power tools.

1. A paper clip acts as a switch On / Off. Enough to withdraw one of the ends of the contact metal tray from the battery to kill power. 2. Clip battery tray red the cable to your battery positive contact metal and the black wire to one of his negatives. 3. The charger has no DIY way of current limiting or preventing overheating. Therefore, at a cost limit of 10 minutes, and remove it when it starts to get hot.

Not There is magic to a cell phone charger. It is little more than a plastic strip of copper wire wrapped designed to deliver power (resigned in tension and becomes DC, of course) an outlet to your phone battery.

So if an emergency arises and you are well, without the charger or working electrical outlet, is actually very easy to macgyver together a device that uses AA batteries to give the phone quickly enough juice to make an emergency call few. The entire process, which resembles a miniature version of launching a car, take a few minutes and used parts can be found at Radio Shack for a total under $ 5.

To do it yourself, you need: a few AA batteries, a plate of four AA batteries, a metal clip and two alligator clips. That is all, and the finished product must be able to charge almost any phone (with the notable exception of the iPhone, which is not easily removable battery) if you is in the desert or waiting out a power outage.

Check voltage

The first step is to check the battery voltage of the phone. The Most clock in around 3.7 volts, but you must leave the phone and read the fine print to do with security. This information will allow you to calculate how many AA batteries it needs. The key is to use enough to barely exceed the phone's battery voltage with fewer and are not produced enough juice to charge the battery, but connect too and could burn the whole thing. AA batteries are 1.5 volts each, so the charge a battery of 3.7 volts, requires the combination of three of them for a total of 4.5 volts.

Pop in the battery tray AA. Is a tray of four of the battery, so you have to put some more in the last AA slot to complete the circuit. This is where the clip comes in handy. Deployment and the hook end through a metal spring at the negative end of the empty slot. Then take the other end and bend to touch the metal contact on the outside of the tray on the positive end of the same slot.

This clip will act as a kind Switch On / Off, as long as it is in contact with the spring and the metal contact, energy will flow and the charger will light.

To activate the charger off, simply move one end of the paper clip out of one of the contacts.

In case of emergency, battery chargers can homemade be used to power other devices as well. And while some devices may require more batteries, the larger C or D cell or battery tray larger, the process is basically the same as for phones. This is how many batteries you'll need to load the most common gadgets. Just make sure it is an emergency. A desperate need to update your Facebook photo can not be worth the risk the process poses to your laptop or camera.

Connect the power supply

For our device to work, plug the battery tray the phone. The tray will have two wires running the same: a red wire carrying current from the battery positive terminal, and a black carrying current back to battery negative terminal. Crimp or solder a red clip to the red wire and a black alligator clip to the black wire. If a voltmeter is available, hooking the clips that I can confirm that your batteries are providing the correct voltage.

Now look closely at the phone's battery. It will have a series of metal contacts used to suck electricity. There must be a positive (+) next to one of them, and a negative (-) side by side. (Note that most phone batteries containing three or more contacts, but you can simply ignore the rest of them. And if brands do not have positive or negative, a voltmeter will tell you which is which.)

Care to ensure that the two clamps from contacting each other, close the red alligator clip to the side of the battery so that its metal jaws are touching the metal contact positive and the black on the side of the battery as it is touching the negative.

The battery is charging. But beware: As this mechanism does not have built makeshift in the form of current limiting or protection against overheating, you'll want to keep an eye (and fingers) on it to ensure they do not get too hot. If the battery the phone starts to heat up, unplug it immediately, or it could damage it. And there are other reasons why you should only try this if you have no choice: the process may violate the warranty of your phone, sharp claws and can scratch up the plastic casing of a battery. And, to be sure, I would not recommend using this method to charge the battery for more than 10 minutes each time. When finished, put the battery in the phone and start dialing.With some AA batteries and a value $ 5, either party can improvise a mobile phone charger emergency. Here's how, and how to expand their construction skills boot-to work in digital cameras, laptops and even power tools.

1. A clip acts as a switch On / Off. Just remove one end of the battery contact metal tray to kill the power. 2. Clip cord red tray battery to your battery positive contact with the metal, and the black wire to one of his negatives. 3. DIY charger has no way to limit or prevent the current overheating. Therefore, limited to 10 minutes in the charges, and removes it when it starts to get hot.

There is no magic to a mobile charger. It is little more than a plastic strip of copper wire wrapped designed to deliver power (resigned in tension and becomes DC, of course) from an outlet for the phone's battery.

Pop in the battery tray AA. Is a tray of four batteries, so you'll have to put something else in the past AA slot to complete the circuit. This is where the clip comes in handy. Deployment and the hook is an end through the metal spring on the negative end of the slot empty. Then take the other end and bend to touch the metal contact on the outside of the tray on the positive end of the same slot.

This clip will act as a kind of switch On / Off-provided that it is in contact with the spring and the metal contact, energy will flow and the charger will light.

For activate the magazine out, simply move one end of the clip away from one of the contacts.

In case of emergency, battery chargers made home can be used to power other devices as well. And while some devices may require more batteries, bigger or cells or tray CD larger battery, the process is basically the same as for phones.

Power Hook Up

For our device to work, plug the battery tray the phone. The tray will have two wires running from it: a red wire carrying current to the battery positive terminal, and a black carrying current back to battery negative terminal. Crimp or solder a red clip to the red wire and a black alligator clip to the black wire. If a voltmeter is available, engaging clips that can be reached to confirm that their batteries are providing the correct voltage.

Now look closely at the phone's battery. It will have a series of metal contacts that are used to absorb electricity. There must be a positive (+) next to one of them, and a negative (-) side by side. (Note that most phone batteries contain three or more contacts, but you can simply ignore the rest of them. And if brands do not have positive or negative, a voltmeter will tell you which is which.)

Taking care not to make sure the two clips do not touch each other, close the red alligator clip to the side of the battery so that its metal jaws are touching the metal contacts positive, and the black on the side of the battery so that it touches the negative.

The battery is charging. But beware: As this unplan mechanism incorporated in the form of current limiting or protection against overheating, you'll want to keep an eye (and fingers) on it to ensure is not too hot.
