Mouse study (part 1/3) -- Battery powered EMF tests & shielding tests

I used a Red & Black Alligator Clip Clamp to 4mm Banana Female Jack Test Adapter 55mm

USB to PS2 PS/2 Cable Converter Adapter (brandname: Valueline)
Before I had this adapter, I fried a mouse, probably because I was using a cheap smaller adapter of 3$, so I advice you to buy one like I'm using in this video.
