Let’s say your CAD workflow is starving for spatial awareness. Your fingers yearn to push, twist, and orbit – not just click. Enter the Nebula Mouse. A 6-DOF DIY marvel, blending 3D printing, magnets, and microcontroller wizardry into a handheld input device that emulates the revered 3DConnexion SpaceMouse – at a hacker price. It’s wireless, […]
3D printing is all well and good for prototyping, and it can even produce useful parts. If you want real strenght in plastics, though, or to produce a LOT of parts, you probably want to step up to injection molding. As it turns out, 3D printing can help in that regard, with injection molding company […]
If you’re like us and you’ve been wondering where those viral videos of single water drop chemical reactions are coming from, we may have an answer. [yu3375349136], a scientist from Guangdong, has been producing some high quality microchemistry videos that are worth a watch. While some polyglots out there won’t be phased, we appreciate the […]
Sometimes, a hack solves a big problem. Sometimes, it’s just to deal with something that kind of bugs you. This hack from [Dillan Stock] is in the latter category, replacing an ugly, redundant downspout with an elegant 3D printed pipe. As [Dillan] so introspectively notes, this was not something that absolutely required a 3D print, […]
You can still get moving-needle meters off the shelf if you desire that old school look in one of you projects. However, if you want a more flexible and modern solution, you could use round displays to simulate the same thing, as [mircemk] demonstrates. At the heart of the build is an ESP32 microcontroller, chosen […]
No, see, it’s what’s inside that counts. Believe it or not, [nobutternoparm] retrofitted this innocent, adorable little tikes® so-called “Kidboard” rubber-dome keyboard into a mechanical marvel. Yeah! No, it wasn’t exactly pure, unadulterated fun, nor was it easy to do. But then again nothing worth doing ever is. Image by [nobutternoparm] via reddit For one […]
Business cards are a simple way to share contact information, but a memorable design can make them stand out. [Jeremy Cook] has been experimenting with adding artistic finishes to PCBs, and has recently applied what he’s learned to make some unique business cards. His write-up consolidates some great resources to get you started in making […]
Once upon a time, typing “www” at the start of a URL was as automatic as breathing. And yet, these days, most of us go straight to “hackaday.com” without bothering with those three letters that once defined the internet. Have you ever wondered why those letters were there in the first place, and when exactly […]
These days, if you’re walking around with a cellphone, you’ve basically fitted an always-on tracking device to your person. That’s even more the case if there happens to be an eavesdropping device in your vicinity. To combat this, the Electronic Frontier Foundation has created Rayhunter as a warning device. Rayhunter is built to detect IMSI […]
The fact that modern-day x86 processors still pretty much support the same operating systems and software as their ancestors did is quite a feat. Much of this effort had already been accomplished with the release of the 80386 (later 386) CPU in 1985, which was not only the first 32-bit x86 CPU, but was also […]
