DO NOT MAKE THIS USING USB!!!! i found out that it can damage your computer from all the comments. my computer is fine tho. Use a 600ma 5v phone charger. i used this and it works fine and nothing can be damaged if u use a safety plug to stop power surges.!!!!!!!!!!!!!!!!!!!!!!!!!!!!
this project will be a usb powered and all you need is a usb wire, metal spring ( i got mine for a pen)/chicken wire(i have not tried chicken wire yet so it may not work.) and 2 croc clips or solder and soldering iron. When i project is complete it will be able to burn and cut plastic and paper and some very fine woods. this project is fun to make but be careful cause it can burn!! but its still pretty cool.
OK IN THE COMMENTS A LOT OF PEOPLE ARE WORRIED ABOUT BREAKING THERE COMPUTER SO IF YOU ARE TRY THIS.
IF you are worried about messing up your computer why not use an old phone charger or adopter.alll u gotta do is get a 5v or more phone charger cut of the top part which goes into the phone and use the red and black wire .(some times the black wires are white in chargers)ALWAYS REMEMBER TO USE A SAFETY ADOPTER WHEN USING MAINS ELECTRIC.
(SAFETY ADOPTER=ONE THAT SWITCHES OFF WHEN THEY IS ABOUT TO BE A SHORT CIRCUIT OR POWER SURG)
this will keep everything you are using safe and will stop you from destroying anything ELECTRICAL in your house.

Step 1: Parts:
ok for this project you dont need very much.
part list :-
1 USB wire
2 Spring for a pen( not all will work, i think chicken wire also works, most fine metal wires do but not thick)
3 croc clips
4 soldering iron if u do not have croc clips
5 wire strippers and a computer to power the usb.
Step 2: USB Power Wire
First cut off one end of the USB wire leaving the one that connects to you computer. after cutting off one end strip 5inch of the wire cover (from the end u cut off) so that you are left with four wires hanging out. cut off the green and white wire as they are not needed.
pin 1 and 2 in the picture are the power wire (red and black).
Step 3: Step 3
now you have to connect a croc clip to each wire so that you have a + croc clip and a - one. like i have done in the picture. next all you do is connect each clip to one side of the spring(stretch the spring first) and the other croc clip to the other side of the spring and thats it. when you plug the USB into the computer the spring should glow orange then u can melt and burn plastic paper and cut through some very thin fine woods. IF you do not have croc clips you can solder the spring to the red wire and the other end of the spring to the black wire.
Below is a picture of a tic-tac box i cut and only took 4 seconds and some paper i burned.
