Ring - Hackaday
This time, he’s exploring a device that appears prefer it could have come from the pages of a Cyberpunk RPG guide - a shiny chrome Bluetooth Low Energy (BLE) smart ring that’s packed with sensors, is reasonably hacker pleasant, and Herz P1 Smart Ring is at the moment selling for as little as $20. The ring’s construction is simple - the surface is polished anodized steel, with the electronics and battery carefully laid out alongside the inside surface, complete with a magnetic charging port.
