How To: Make a Homemade USB Mobile Phone (Nokia) Charger

You may find it useful to charge your phone at the go, and it can be bothersome to bring a charger with you at alle times. There is however very easy to bring a simple, small USB-charger. They can be bought for a buck at eBay, but it is also very easy to make one yourself!

I made a Nokia charger since i use that phone brand. It can be done with other brands too.

The first thing you should check, before attempting to build this, is the Voltage and Amperage that your phone charges at. You can read it on the wall-charger. My nokia charger sended 5V DC, and 350ma, but I found out that there were Nokia chargers that gave up to 800ma. Since the USB-port provides a
Voltage of 5V, DC and an Amperage of max 500ma, this suited my phone.

Now, to make the USB-charger You will need:

- a USB cable with a male end
- a wall charger (you will only need the tip or "head" that connects to the phone)








 I got my USB-cable from an old webcamera that was broken, and I cut of the USB-cable from it. I stripped out the 4 wires, and cleared out the red and black, which carries the power.

 















The charger head i got from a spare Nokia charger i had lying around. I cut of the cable, seperated and cleared the two wires inside.

The next thing I did was to clear the wires apart from eachother, and then I connected, (or twisted) the red wire from the USB-cable, to the red wire on the head-cable, and did the same with the black ones.   

NOTE: MAKE SURE THAT THESE TWO WIRES, (Red-Red) and (Black-Black) REMAIN SEPERATE AND PREVENT THEM FROM TOUCHING EACHOTHER, AS THIS CAN LEAD TO A SHORT CURCUIT.

In order to prevent the wires from touching eachother, I seperated the red and black wire with electrical-tape, and then I sealed it all up with some more tape.

I connected it to the PC, and my phone started charging.


I made my cable very long, but you don't have to. Choose a lenght that suites you. 

Enjoy!

Backflip on Trampoline Tutorial

To do the backflip on the trampoline is often one of the biggest challenges for some, and after you mange to do it, you really start to learn alot of new tricks.

But to do the first backflip can be really hard for some. I will give you some tips on how to do it.

To do a backflip on a trampoline, you should be able to do a proberly frontflip, and have some flexibility. 

1. Fear
The main reason people cannot do a backflip is the fear. You feel scared for failing, and it really sucks on the first attemps. A way to avoid the fear is to consentrate, and make yourself feel safe. You must focus on the movements, and you must tell yourself it's gonna work.

2. Height
The more height you get, the more time and space you have in the air. In the beginning, start jumping in the middle of the trampoline, and jump high. Make sure you don't waste your height right before the backflip, this is a common mistake. 

3. The air-kicks
The movement of the backflip is not powered by jumping backwards. You should jump straight up. You can use your legs, and your hands to power yourself around in the beginning. The first backflips you should attempt are the air-kicks. A kick in the air can drag you alot around, so start to by jumping up, and use one of your legs to kick up and behind you. Your body will follow the leg around, you will actually do a backflip. This is also a great way to feel safer about the flip. When your head has passed 180 degrees, you are sure you wont land on your neck.

4. Tugging
When you feel safer about the backflip, and manage the footkick, you can start on the next method. Jump high, and jump straight up, NOT BACKWARDS. Lean backwards in the air, and tug your arms over your head, and tugg your legs upwards. It should give you enough power, and you will go around.

5. Leaning
The more safe you get, the easier it is to do the backflip. Eventually, you can just lean backwards and do a smooth backflip.

Remember, always be careful. If you're not sure you cannot do it, dont.
