Need Help Sourcing Parts for My Smart Ring Design
Asked by User8392xD
I'm working on designing my own smart ring, and I want it to be similar in size to the Oura Ring. I'm aiming for a design that features a single button and USB-C charging for tracking arm movements. Here are the parts I'm considering: a microcontroller, an IMU, a LiPo battery, a LiPo battery charger (like a TP4056), and a tactile switch. I'm really new to this, so I could use some guidance on whether these parts are suitable and if I'm missing anything. Any help would be appreciated!

Honestly, coding might end up being the simplest part of this project! You'll definitely want to look for a super small LiPo battery, something around 25mAh, and a tiny microcontroller like an ATtiny. Also, consider a capacitive touch switch instead of a physical one; it'll help save some space.
