Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in …read more Continue reading Building Reaction Wheels With Python and LEGO
There’s a fine line between simple feature creep and going over the top when it comes to project design. It’s hard to say exactly where that line is, but we’re …read more Continue reading Filament Dry Box Design Goes Way Over the Top
If you wanted to, say, control a temperature you might think you could just turn on a heater until you reach the desired temperature and then turn the heater off. …read more Continue reading Pico Does PID
We are big fans of the little desktop magnetic levitation setups that float a small object on a magnet. As [3D Printed Life] points out, they look like magic. He …read more Continue reading Fail of the Week: Magnetic Levitation
A self-balancing robot isn’t a new idea, but we liked the aesthetics of [Maker ATOM’s] build. The use of a breadboard and a printed bracket looks good, as you can …read more Continue reading Self Balancing Robot Needs a Little Work
While a line-following robot may not be the newest project idea in the book, this one from [Edison Science] is a clean build using modern components and gets a good …read more Continue reading Line Following Robot uses PID for Speed
[Leo Fernekes] has fallen down the Sterling engine rabbit hole. We mustn’t judge — things like this happen in the best of families, after all. And when they do happen …read more Continue reading This Custom Dynanometer Is A Sterling Example of Homebrewing
When we first saw [Barqunics’] design for a self-stabilizing spoon for people suffering from Parkinson’s disease, we wondered how well something like that could work. But take a look at the video below and you’ll see this does a fine job of responding to the user’s hand movements and keeping …read more

He wanted to incorporate all the popular beginner robot capabilities into …read more
