Touch Electrical Current with the Thunder Finger

I stuck a fluxgate magnetometer to my finger, connected it to a wristband that feels sounds, and added a rainbow LED matrix, so I can feel electric current flowing through circuit boards and walls.

Why? Because I slammed too many cocktails and entered Hackster.io’s contest to Expand the Human Experience. They sent me a Neosensory Buzz haptic wristband, and now I need to augment myself or get cut off from free hardware forever. Just a normal day in Voidstar Lab.

Enter the contest.
