[Emiel] aka [The Practical Engineer] makes all kinds of fun projects in his fully-featured shop, and one of his tangents has been building a series of solenoid engines. These engines …read more Continue reading Can the Solenoid Engine Power a Car?
The versatility of 3D printers is simply amazing. Capable of producing a wide variety of prototypes, miscellaneous parts, artwork, and even other 3D printers, it’s an excellent addition to any …read more Continue reading A 3D Printer with an Electromagnetic Tool Changer
Wind energy isn’t quite as common of an alternative energy source as solar, at least for small installations. It’s usually much easier just to throw a few panels and a …read more Continue reading Full Size 3D-Printed Wind Turbine
[JK Lee] has been experimenting with a monorail tripteron motion control system (video, embedded below) and trying to improve performance with varying tweaks to the design and with varying degrees …read more Continue reading Trippy Tripteron Kinematics Brainteaser
3D printers are an excellent tool to have on hand, largely because they can print other tools and parts rapidly without needing to have them machined or custom-ordered. 3D printers …read more Continue reading Robot Arm Adds Freedom to 3D Printer
When it comes to toolchanging 3D printers, idle nozzles tend to drool. Cleaning out that nozzle goo, though, is critical before switching them into use. And since switching nozzles can …read more Continue reading Toolchanging Printers Get a Nozzle Hanky Like No Other
For the price of a toothbrush and a small motor with an offset weight, a bristlebot is essentially the cheapest robot that can be built. The motor shakes the toothbrush …read more Continue reading Random Robot Makes Random Art
For all but the most experienced gardeners and botanists, taking care of the soil around one’s plants can seem like an unsolvable mystery. Not only does soil need the correct …read more Continue reading Fertilizing Plants With A Custom 3D-Printed Pump
We’re all too familiar with the 3D printing post-processing step of removing supports, and lamenting the waste of plastic on yet another dwindling reel of filament. When the material is …read more Continue reading Dynamic Build Platforms for 3D Printers Remove Supports and Save Material
Want a closer, in-depth look at E3D’s motion system and tool-changing platform? [Kubi Sertoglu] shared his impressions after building and testing the system, which comes in the form of a …read more Continue reading Get a Better Look at E3D’s Tool-changing 3D Printer Kit
