Homemade CNC Machine From DC Servo Motors and Wooden Wine Boxes

Today, I would like to share how to build a 3 axis CNC machine at home using available or discarded materials. Specifically in this project, I reused 2 old DC servo motors and 2 wooden wine boxes, as well as, taking advantage of my daughter’s unused school supplies. Step 1: Supplies The main materials are …

ROVER-USES-DIFFERENT-KIND-OF-TRACKS

ROVER USES DIFFERENT KIND OF TRACKS

Tracked robots usually require at least two wheels inside to work properly. However, [James Bruton] discovered a curious tractor design from the 1940s, the Fordson Rotaped, which only uses a single sprocket wheel inside each track. Being [James], he built aΒ self-balancing robot around the rotaped concept. Instead of a lot of short track sections, the …

AUTO-AIMING NERF GUN TO GIVE YOU THE EDGE IN BATTLE

Ever wished for some robotic enhancements for your next nerf war? Well, it’s time to dig through the parts bin and build yourself aΒ nerf gun with aimbot built right in, courtesy of [3Dprintedlife]. (Video, embedded below.) The gun started with a design borrowed from [Captain Slug]’s awesome catalog of open source nerf guns. [3Dprintedlife] modified the …

BALANCED-DESIGN-AND-HOW-TO-KNOW-WHEN-TO-QUIT-OPTIMIZING

BALANCED DESIGN AND HOW TO KNOW WHEN TO QUIT OPTIMIZING

I got a relatively inexpensive 6040 CNC machine, and have been spending most weekends making the thing work, and then cutting stuff, learning the toolchain, and making subsequent improvements. Probably 90% of my machine time has been on making improvements. It’s not that the machine wasΒ badΒ β€” I got the version with ballscrews and a decently …
