Welcome to a new Voltlog, in this video I’m gonna show you how I built this project where an ESP32 based smart wristband allows me to track the progress of my 3D printer in real time. So I thought about how I could solve this problem and I came up with a project where I’m using a LILYGO T-Wristband which is basically an ESP32 development platform built into this smart bracelet form factor. The bracelet connects via Wifi to the local network where Octoprint runs and manages the 3d printer.
