The weird pads you see on my arm are part of a thing called a TENS unit, it is a muscle recovery device which runs a small current through your muscle and makes it contract, a python code is checking if my recent follower updates, if it does then it will send a signal to a relay board which allows current to flow.
TL;DR: any notification (follows, channel points, subs etc.) makes my arm contract
