Wrist version of the EMF sensor

29 Mar

Stuffed into a wristband, here’s an Arduino Pro Mini, a LiPo battery and boost converter to get 5V, a couple of LEDs, and the EMF antenna and code. See it glow red AND green when a compact fluorescent light is turned on nearby! Red LED shows 60Hz, green shows “everything else”
