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.
