This single-mirror 3D-printed wearable clips onto existing glasses to deliver a customizable head-up display.
The author, inspired by his dad's old HP 25 calculator, designs and 3D prints a new battery holder to revive the vintage device.
This Instructable details the creation of an ultra-compact LiDAR distance meter, featuring a tiny OLED display, VL53L0X sensor, and Xiao ESP32C3 microcontroller. The project involves 3D printing, soldering, and coding to build a functional, portable device for measuring distances.
