3D printing is a great way to create complex geometric forms. However, it can be very slow, and parts may lack strength compared to other alternatives. There are other ways to take advantage of this technology however, as shown in the build of this tidy voronoi lamp. The lamp is so-called for its voronoi-patterned base, […]
If you were tasked with designing a color video monitor, it’s pretty clear how you’d go about it. But what if you’d been asked to do so 20 years ago? Would it have been a cut and dried from an engineering standpoint? Apparently not, as this hybrid LCD-CRT video monitor demonstrates. We’d honestly never heard […]
Ostensibly the ESPboy is an open-source hackable game engine built as an IoT platform for STEM education and play, but there’s no way [RomanS] could have been inspired by anything other than retro gaming consoles from the near past. For anyone who grew up playing with Tamagotchi pets or Palm Pilots, this project is going […]
Some hacks are born of genius or necessity, and others from our sheer ham-fisted incompetence. This is not a story about the first kind. But it did give me an excuse to show how easy it is to design WiFi-connected devices that work the way you want them to, rather than the way the manufacturer had […]
It’s officially October, and that means we can start unleashing the Halloween hacks. Take for example this restless skeleton that master automaton maker [Greg Zumwalt] has doomed to spend eternity inside of a useless box. If that wasn’t enough to wake the dead, every time some joker pushes the button, these blinky lights come on. […]
Back in the good old days of carburetors and distributors, the game was all about busting door locks and hotwiring the ignition to boost a car. Technology rose up to combat this, you may remember the immobilizer systems that added a chip to the ignition key without which the vehicle could not be started. But […]
There are many ways to attach a project to the Internet, and a plethora of Internet-based services that can handle talking to hardware. But probably the most ubiquitous of Internet protocols for the average Joe or Jane is the web browser, and one of the most accessible of programming environments lies within it. If only […]
Thermal inserts are a big thing when it comes to engineering with plastic. They make it easy to use threaded fasteners with plastic parts, and they work great with 3D printing too. There’s a bit of a knack to installing them without damaging your workpiece, however, and [John Culbertson] wanted to make using them as […]
If you look at enough of another developer’s code, you will eventually say, “What were you thinking, you gosh-darn lunatic?” Now, this exchange can precede the moment where you quit a company and check into a padded room, or it can be akin to calling someone a mad genius and offering them a beer. In […]
It wasn’t long ago that we introduced you to a web site, the Godbolt compiler explorer, that allows the visitor to compile code using a slew of compilers and compare their output. We suspect some number of readers said, “Wow! I can use that!”, while perhaps everyone else said, “Huh?” Well if you were in […]
