Welcome back! If you’ve been following along in my RockARM series, and already 3D printed your RockARM case, then it’s time to fill it with some delicious hardware! In the video below, I take you through the hardware components and assembly, tools and tricks for getting everything built up nicely. After...
Today we’re going to step through the process of 3D printing the RockARM Home Edition parts! Click the link below to download the complete package, zipped and compressed. Please take a moment to read through the contained README file, for special instructions to successfully print the parts, especially the main housing...
This is my latest project, IRL 🙂 Most of my projects are computer-related, and though this one has some technical electronic aspects to it, it’s largely a mechanical and electrical engineering project. I’ve been fascinated with the development of electric scooters over the years. In recent years with companies getting in...
I’m so excited to share this project! This combines just about everything that I love in projects: 3D printing, containers, building, design, and the pursuit of low-power efficiency! Okay, so what is this? Let’s start with a little background, and context first: We all have some form of a home lab,...
Welcome back! In this episode, I’m taking you through how to manage your deep-sleep mode battery-powered IoT sensors remotely, using MQTT retain flags. This lets you catch the device at its’ next wakeup interval and keep it online, so you can do a firmware update, then put it back in its’...
Let’s get some ESPHome firmware flashed on to your ESP32 solar-powered IoT project! I’ll show you the basics of building the base firmware to get it attached to your WiFi network, some tips and tricks for working with mDNS across subnets, and leave you with a working OTA-managable solar-powered sensor! Code...
Let’s get your newly-deployed Home-Assistant instance set up, get those day-one add-ons installed, and get some best practices for backups and updates knocked out!
In this video, we built a solar-powered, 18650 battery-backed ESP32-powered sensor, sitting in a compact 3D printed housing. This is using a temperature, humidity and barometric pressure sensor, known as the BME280, which runs on the i2c bus. Additionally, we’re using a TP4056 charge controller, the updated version with low-voltage protection!
This project was a lot of fun, and slightly terrifying at the same time. You take a perfectly good iPhone XR with not a scratch on it, and tear it down, void its’ warranty, all to install a ring of magnets so it will work with MagSafe. What could possibly go...
