Adding LEDs to a project used to be enough to make it cool. But these days, you need arrays of addressable multi-color LEDs, and that typically means WS2812B or something similar. The problem is that while it was pretty easy to test garden-variety LEDs, these devices can be a bit harder to troubleshoot. [Gokux] has […]
There are many ways to hack the world. Graduate students at Parsons The New School for Design developed a guide for hacking the biggest piece of technology humans have developed – the city. One of the things we love here at Hackaday is how hacking gives us a tool to make the world a better […]
If somebody asked you to visualize a CNC router, you’d probably think of some type of overhead gantry that moves a cutting tool over a stationary workpiece. It’s a straightforward enough design, but it’s not without some shortcomings. For one thing, the scale of such a machine can quickly become an issue if you want […]
“World’s best” is a mighty ambitious claim, regardless of what you’ve built. But from the look of [Marius Hornberger]’s tricked-out miter fence, it seems like a pretty reasonable claim. For those who have experienced the torture of using the standard miter fence that comes with machine tools like a table saw, band saw, or belt […]
Vacuum forming is perhaps one of the less popular tools in the modern maker arsenal, something which surprises us a bit because it offers many possibilities. We’ve created our own vacuum forms on 3D printed moulds for ages, so it’s interesting to see [Pisces Printing ] following the same path. But what you might not […]
Last year, we saw [How To Make Everything’s] take on [DaVinci’s] machine for cutting threads. However, they stopped short of the goal, which was making accurate metal screw threads. After much experimentation, they have a working solution. In fact, they tried several different methods, each with varying degrees of success. Some of the more unusual […]
It’s common problem when you’re building anything with screws: this one is too long, this one is too short. While she can’t teach you how to fix the latter, [Quinn Dunki] has made herself an absolutely deluxe screw shortening jig. And while that’s cool and all, the real value here is the journey; watching over […]
[Chris Borge] was doing some fine tapping operations, and wanted a better way to position his workpieces. This was critical to avoid breaking taps or damaging parts. To this end, he whipped up a switchable magnetic vice to do the job. The key to the build is that the magnetic field can be switched on […]
Woodworking tools like table- and bandsaws are extremely useful and versatile, but they generally have the distinct disadvantage that they make no distinction between the wood and the digits of the person using the machine. While solutions like SawStop were developed to make table saws sense flesh and try to not cut it, [James Hamilton] […]
