How to take apart a USB plasma globe, which contains a tesla coil, wire it to work on a battery, and get neat little sparks from it. It can set thin paper on fire ... and it does something weird when a magnet gets near it ...
As I will explain later this deals with HIGH VOLTAGE so please, if you are a minor, do this with the supervision of an adult, and if you are an adult, dont do this alone in case you zap yourself and need CPR. Warning! Danger!
That said, I got this globe at Best Buy for $20 bucks (USD) in the computer section.
Step 1: Open the box and take out the globe
on the bottom will be screws ... use a philips head screwdriver to remove them, then put the screwdriver into one of the screw holes to gently pop out the bottom of the base
Step 2: Pull out the wire from the globe
Use the screwdriver to pull the red wire up from out of that black plastic tube in the center of the globe. Its just stuffed up in there so it should come out easily.
Step 3: Take out the circuit board
This step is optional, and in later steps I have put the circuit board back INTO the base. So you may want to hold off on this step until you have another good container to mount the board into.
But note this first pic as it details whats what on the power wires going into the circuit board.
Use the screwdriver to remove the two screws that are holding the circuit board from the plastic case. Take care not to touch the metal parts of the circuit board in the process.
