Description
For my son's Christmas present last year I made him a pair of heart-rate monitoring earrings with pulsing LED display in the form of a human heart. They can also be used as a BLE heart-rate monitor. From a design perspective they focus on power management and battery life. They have received a lot of complients and some enquiries about availability for purchase.
