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 …

This project was completed by Alexandra Pittiglio & Christelle Feghali for our Computational Design and Digital Fabrication ‘Useless Machine’ Project, Semester 2, ITECH M.Sc Programme ——– We present Plant Bartender, a 2-axis robot that senses and waters in the most inefficient way. This device utilizes soil moisture sensors to identify the thirst levels of multiple …
Analog and mixed-signal semiconductor company MagnaChip Semiconductor (Cheongju-si, South Korea) has announced the release of a 100-V mid-voltage MOSFET with a new thermal package designed for the fast-growing electric bike (e-bike) market. The MOSFET is housed in a M2PAK-7P package suitable to meet the particular requirements of electric bike (e-bike) systems, which are powered by electric motors …

The holidays always remind us of our favorite toys from when we were kids. Johnny Astro, an Erector set, and — of course — a Spirograph. [CraftDiaries] has an Arduino machine that isn’t quite a Spirograph, but it sure reminds us of one. The Arduino drives two stepper motors that connect to a pen that can …
Hi every one, here Chris, and I want to show you how I made my own Arduino AC dimmer that can control AC loads such as motors and lights easily. It has the power to handle 1200+ Watts and It’s a very nice project for domotics and home automation because the microcontroller I used is …

{This instructable was created in fulfillment of the project requirement of the Makecourse at the University of South Florida (www.makecourse.com).} Inspired by the Wind powered machines built by “Theo Janse” I’ve come up with a design of my own, but with a twist. This design houses two 12volt motors to provide the power, an Arduino, …
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 a self-balancing robot around the rotaped concept. Instead of a lot of short track sections, the …
Ever wished for some robotic enhancements for your next nerf war? Well, it’s time to dig through the parts bin and build yourself a 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 …

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 was bad — I got the version with ballscrews and a decently …

It would be great if you could create your own filament. On the face of it, it seems easy to do, but as [Thomas Sanladerer] found out when he was a student, there are a lot of details that can bedevil your design. His extruder sort of works, but he wouldn’t suggest duplicating his effort. In fact, …
