[sc:3dclub-intro] 3D printers are an exciting new technology just starting to gain a foothold in schools. Once built, a printer facilitates many creative endeavors and links to math, science, art, and more. Building a 3D printer is a great project…
I built a framework for robot wheels a while back using OpenSCAD and used it to create a few different wheel styles. I recently decided to combine them all into one massively configurable wheel model, and add a number of…
Math Monday came early this week, and we had some fun exploring Reuleaux triangles. Next to a circle, they’re the simplest curve of constant width you can make — that basically means you can roll a plank on top of…
To mark the 63rd anniversary of the first stored computer program to run (June 21), I rewrote the original code in C# last night, both using the original algorithm (that was never intended to be efficient) and using a more…
