[Fraens] has been re-making industrial machines in fantastic 3D-printable versions for a few years now, and we’ve loved watching his creations get progressively more intricate. But with this nearly completely 3D-printable needle loom, he’s pushing right up against the edge of the possible. The needle loom is a lot like the flying shuttle loom that […]
Whatever the nuances are surrounding the reported taking down of remixes derived from the famous Benchy 3D printer stress test, it was inevitable that in its aftermath there would be competing stress tests appear under more permissive licensing. And so it has come to pass, in the form of [Depep1]’s Boaty, a model that’s not […]
In the world of showing off, there is alongside ‘Does it play Doom?’ that other classic of ‘Does it play Bad Apple?’. Whereas either would be quaint in the context of the Vim editor, this didn’t deter [Nolen Royalty] from making Vim play the Bad Apple video. As this is a purely black and white […]
Telephone systems predate the use of cheap computers and electronic switches. Yesterday’s phone system used lots of stepping relays in a box known as a “selector.” If you worked for the phone company around 1951, you might have seen the Bell System training film shown below that covers 197 selectors. The relays are not all […]
When we reviewed the iFixit FixHub back in September, one of the most interesting features of the portable soldering station was the command line interface that both the iron and the base station offered up once you connected to them via USB. While this feature wasn’t documented anywhere, it made a degree of a sense, […]
[Boz] wants to build a retrocomputer, but where to start? You could start with the computery bits, like say the CPU or the bus architecture, but where’s the fun in that? Instead, [Boz] built a righteous blinkenlights array. What’s cool about this display is that it’s ready to go out of the box. All of the […]
Hackaday was at Chaos Communication Congress last week, and it’s one of those big hacker events that leaves you with so much to think about that I’m still processing it. Just for scope, the 38th CCC is a hacker event with about 15,000 attendees from all around Europe, and many from even further. If I […]
Adding threads to your 3D prints is a life-changing feature, but obviously there are a lot of trade-offs and considerations when deciding on how to go about this exactly. Between self-tapping screws, printed threads, heat inserts and a dozen other options it can be tough to decide what to go with. In a recent video […]
A research project shows that it’s possible to create complex single-piece lenticular objects, or objects that have lenticular lenses built directly into them. The result is a thing whose appearance depends on the viewer’s viewpoint. The object in the image above, for example, is the same object from five different angles. What’s really neat is […]
Doing the rounds this week is a new operating system for ESP32 microcontrollers, it’s called Tactility, and it comes from [Ken Van Hoeylandt]. It provides a basic operating system level with the ability to run apps from an SD card, and it has the choice of a headless version or an LVGL-based touch UI. Supported […]
