DIY Word Clock - 3D Printed

This 3D printable Word Clock displays the time in full sentences by lighting up the hidden words in amongst the jumble of letters. It also features a replaceable and customisable clock face so you can add your own design flair to your project.

It can be printed and assembled over a weekend.

Sensorless Homing with RP2040 & TMC2209

By Lewis • February 24, 2026

In this video, I’ll show you how to set up sensorless homing using a TMC2209 stepper driver — no mechanical limit switches required! Perfect for 3D printers, CNC machines, robotics, and other DIY electronics projects. I’ll guide you through the wiring, Arduino code, and how to tune StallGuard for accurate, reliable homing. Whether you’re building a CoreXY, a custom motion control system, or just want to learn more about stepper motor drivers, this is a great place to start. Let’s build smarter! Why would we want to use sensorless homing? Well first the Pros…. There’s no need for extra mounts, additional components or running long dangling cables to one or both ends of the carriage or other moving component. And there are always cons, so in this case you’ll need a stallguard-capable driver (they cost a little more and are only manufactured by Trinamic) and accuracy isn’t great at slow speeds.
