Introduction: DIY TINY PLASMA CUTTER

This project is not very useful, but it's still fun.

Step 1: Watch the Video

Step 2: What You'll Need

You will need these tools:

_Alligator clips

_A power supply that can deliver a considerable amount of current (an ATX power supply is totally fine)

You'll also need these materials:

_Aluminium foil

_A paperclip

Step 3: The Wiring

Connect a piece of foil to the ground an a unmade paperclip to the +12 volts.

Step 4: Let's Have Some Fun!

Now, just just need to touch the edge of the foil with the paperclip and watch small plasma-arcs forming at the contact point. And if you need to cut a precisely shaped hole in a sheet of foil, this thing can even be useful! :D

    How could this project be scaled up, to say, be able to weld aluminum??

    i weld with 2 12v batteries in a series. attach what yo want to weld to the -- wire and a carbon rod to the + wire. just touch the carbon rod to the metal you want to weld and look away!

    You'll need some welding rods and MUCH more current. You can hack some microwave oven transformers to transform them into ''converters'' (just replace the second coil with a thick copper wire). Like this, your 12 volts and 32 amps from the beginning will become 1.5 volts and 75 amps, and then, you'll be maybe able to weld something.

    75 amps will certainly melt something, but 1.5 volts isn't going to give you any penetration of the metal which is necessary for a strong weld.

    True, but you can still weld metals witha very low melting point, like gallium (even if it's in the TOP 10 of the most useless things in the world).

    its not a plasma (just aluminum heated by high currency flow through thin conductor)
