ESPHome Temperature and Humidity Sensor with Home Assistant

I needed to add a simple temperature and humidify sensor to add to Home Assistant, both for my information and for various automations. At first, I went with the Aqara temperature and humidity sensor, but they were too unreliable with my setup. Even if I can get them to pair, they often will drop after…

A quick introduction to OpenSCAD for 3D printing

I’ve purchased an Ender 3 Pro 3D printer some time ago, but I only did a few demos prints at the time. I didn’t know where to start designing my own models, so the printer sat there collecting dust. The whole process of learning to model just to create a custom print sounded like a…

HC-SR04 Ultrasonic Sensor with Arduino

To detect objects at a distance in your Arduino projects, the HC-SR04 ultrasonic sensor is a common option. It comes as a board that’s easy to integrate in your projects, and it can be bought for pretty cheap. To learn more about this sensor I built a quick project on a breadboard to test it…
