Ring - Hackaday

This time, he’s exploring a device that appears like it may have come from the pages of a Cyberpunk RPG guide - a shiny chrome Bluetooth Low Energy (BLE) Smart ring sleep tracker ring that’s packed with sensors, is moderately hacker pleasant, and is at the moment promoting for as little as $20. The ring’s construction is straightforward - the outside is polished anodized steel, with the electronics and battery fastidiously laid out along the inside floor, full with a magnetic charging port. It has a BLE-enabled MCU, a heartrate sensor, and an accelerometer. It’s not much, but you can do too much with it, from the usual exercise and sleep tracking, to a faucet-delicate interface for anything you want to manage from the palm of your hand. In the video’s feedback, somebody famous how a custom firmware for the ring could be used to detect seizures; a perfect example of how hacking such devices can deliver someone a brighter future.

We’d suggest ordering a couple now earlier than sellers get wise and begin elevating costs. Whereas we’ve seen hackers construct their own sensible rings earlier than, it’s tough enterprise, and the top results often have very limited capability. The potential for creating our personal firmware for such an affordable and capable gadget may be very exciting - watch this house!
