Early LED displays came in all sorts of configurations. Because the LED was fairly new technology, all kinds of ideas were getting tried, and with all that work there was …read more Continue reading This Vintage LED Matrix Lives in a Gold Bathtub
Here’s how FreeCAD works: the program’s design space is separated into different “workbenches”, each of which is intended for a particular set of operations, and a piece of work can …read more Continue reading FreeCAD Takes Off With a Rocket Design Workbench
This mini handheld chainsaw by [Make it Extreme] is based around an electric motor from a car door, the same ones used to raise and lower car windows. They are …read more Continue reading Electric Window Motor Becomes Mini Chainsaw
Back before LED technology came into its own, displays used incandescent bulbs. These vintage incandescent displays weren’t necessarily big; the Eaton 925H-C fiber optic display, for example, has numbers barely …read more Continue reading Over-Engineered Incandescent Numerical Display Shows Great Workmanship
[Jacob Stanton]’s design for 3D-printable, stacking and locking boxes is a great example of design for manufacturability (DFM). MicroStacks show how part of good DFM is taking the manufacturing method’s …read more Continue reading To Lovers of Small Boxes: a 3D Printable Design Just for You
A cutdown in high-altitude balloon (HAB) parlance refers to detaching a payload, and can refer to the act of severing a line or to the mechanism itself. How is this …read more Continue reading Archery Release Becomes Reusable Balloon Cutdown Mechanism
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
The Onion Tau LiDAR Camera is a small, time-of-flight (ToF) based depth-sensing camera that looks and works a little like a USB webcam, but with a really big difference: frames …read more Continue reading New Part Day: Onion Tau LiDAR Camera
Perlin noise is best explained in visual terms: if a 2D slice of truly random noise looks like even and harsh static, then a random 2D slice of Perlin noise will have a natural-looking blotchy structure, with smooth gradients. [Jacob …read more
