Sometimes you just gotta sit down and hack something together. Forget the CAD and the cool software toys; just hammer away until you have something working. That’s how [bobricus] ended up with this cute little laser engraver anyway. For under $300 US of parts and a few nights working in his pajamas, the aptly named, […]
[Dan Royer] is taking some inspiration from Prusa’s business and is trying to build the same sort of enterprise around open source 3D printable robot arms. His 6 axis robot arm is certainly a strong first step on that road. As many people have learned, DIY robot arms are pretty difficult. [Dan]’s arm has the […]
A test exposure on cyanotype paper shows off the prototype’s resolution, around 100 microns. Typically, when it comes to scanning a laser, it’s done with galvos or a rotating mirror assembly. However, these methods can be slow and cumbersome, or restricted due to existing patents. [Rick] aimed to find an alternative solution with the Hexastorm […]
In the time since the Hackaday Prize was first run it has nurtured an astonishing array of projects from around the world, and brought to the fore some truly exceptional winners that have demonstrated world-changing possibilities. This year it has been extended to a new frontier with the launch of the Hackaday Prize China (Chinese […]
With microcontrollers growing ever more powerful each new generation, things that were mere pipedreams before are now readily possible. The Shapeshifter drum machine is a perfect example. Shapeshifter’s design is open-source, with everything available on Github for the curious musical tinkerers out there. The device is built around a PCB with only through-hole components, making […]
Portrait painting is, by and large, a human endeavour. But, like any and all skills, there are machines ready and willing to take a crack at it. [Jose Salatino] has built just such a machine, and the results are impressive. Samples of the artwork created by [Jose’s] portrait painter. [Jose’s] portrait painter relies on a […]
If you’re like most people, then washing clothes is probably a huge pain for you. Figuring out the odd number of minutes necessary to run a wash and dry cycle, trying desperately not to end up with clothes that are still wet, and worst of all having to wait so long for your clothes to […]
A device that even DIY enthusiasts don’t usually think to DIY is the humble soldering iron. Yet, that’s exactly what one Hackaday.io user did by building a USB-powered soldering pen with better performance than a $5 Chinese soldering pen. The project draws inspiration from another Weller RT tip-based soldering pen by [vlk], although this project has […]
For many environmental enthusiasts, horizontal-axis wind turbines (HAWTs) — the kind that look like windmills slowly spinning in the distance — are a pretty familiar sight. Unfortunately, there are quite a few caveats that make them harder to adopt despite the fact that harvesting renewable energy sources is more sustainable than relying on natural gas […]
Many cameras these days have optional remotes that allow the shutter release to be triggered wirelessly. Despite this, [Foaly] desired more range, and more options for dealing with several cameras at once. As you’d expect, hacking ensued. [Foaly] uses Silver modules to photograph rocket launches safely. The system goes by the name of Silver, and […]
