Electric vehicles are everywhere these days, and with them comes along a whole slew of charging infrastructure. The fastest of these are high-power machines that can deliver enough energy to charge a car in well under an hour, but there are plenty of slower chargers available that take much longer. These don’t tend to require […]
Not so long ago, most computer users didn’t own their own machines. Instead, they shared time on mainframes or servers, interacting with this new technology through remote terminals. While the rise of cloud computing and AI might feel like a modern, more dystopian echo of that era, some look back on those early days with […]
[Matt Denton]’s SpoolBot is a surprisingly agile remote-controlled robot that doesn’t just repurpose filament spool leftovers. It looks exactly like a 2 kg spool of filament; that’s real filament wound around the outside of the drum. In fact, Spoolie the SpoolBot looks so much like the real thing that [Matt] designed a googly-eye add-on, because […]
Even though digital cameras have lowered the barrier of entry to photography dramatically, as well as made it much easier for professionals and amateurs alike to capture stunning images without the burden of developing film, the technology behind them is considerably more complex than their analog counterparts. In fact, an analog film camera (not counting […]
Magnet placement tools are great because they remove finger fumbling while ensuring correct polarity every time. [EmGi] has made a further improvement by making a version that auto-feeds from an internal stack of magnets. A stack of magnets auto-feeds with every press of the plunger. That is a trickier task than one might imagine, because […]
[GizmoThrill] shows off a design for an absolutely gorgeous, high-fidelity replica of the main character’s helmet from the video game Satisfactory. But the best part is the technique used to create the visor: just design around a cheap set of full-face “sunglasses” to completely avoid having to mold your own custom faceplate. One of the […]
[XYZAiden]’s concept for a flexible robotic gripper might be a few years old, but if anything it’s even more accessible now than when he first prototyped it. It uses only a single motor and requires no complex mechanical assembly, and nowadays 3D printing with flexible filament has only gotten easier and more reliable. The four-armed […]
Need a plastic mesh in a custom pattern? 3D print it, no problem. But what if one needs a curved plastic mesh? That’s considerably harder to 3D print, but [Uncle Jessy]’s figured out a simple approach: 3D print the mesh flat, then break out a mold and a heat gun. Of course, there are a few […]
Syringes are pretty ergonomic, but when manually dispensing flux and solder paste it doesn’t take long before one wants a better way. [Elektroarzt]’s flux and solder paste dispenser design uses 3D-printed parts and minimal hardware (mostly M3x20 screws, and an optional spring) to improve handling and control. The operating principle is very similar to how […]
