Keeping track of your 3D-printer filament use can be both eye-opening and depressing. Knowing exactly how much material goes into a project can help you make build-versus-buy decisions, but it can ...

Back in school, I spent more hours than I can count hunched over an Arduino Uno – blinking LEDs, wiring up sensors, and building clunky robots that barely worked but felt like magic. The Uno was ...

This DIY 6-DOF robot arm project details a two-year build cycle using 3D printed parts, custom electronics, and over 5,000 ...

[Fabian Chouteau] built a plotter out of CD-ROM parts. Yawn, you say? Besides being a beautiful physical build, this one has a twist. He wrote the software and firmware for the entire project himself, ...
