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 …read more
This servo/gear reduction was assembled with almost all 3D-printed parts. Apart from a brushed 36 V DC-motor, a stainless steel shaft, and screws for holding the servo together, the only other non-printed part is the BTS7960B motor driver.
Some interesting stats about the plastic servo – its stall torque is …read more
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 …read more
There’s been a lot of Altoids tin hacks over the years, but a vacuum cleaner in a tin is something new. In [Toby Bateson]’s first project on Hackaday, he used simple household items to create a functioning vacuum cleaner to use for sucking crumbs out of your keyboard or paper …read more

While we certainly do love the Arduino Nano for its low-cost and versatility in projects, it’s unarguable that every tools has its gripes. For one maker in particular, there were enough complaints to merit a redesign of the entire board. While Arduino may or may not be interested in incorporating …read more
Fans of D&D are surely aware of the significance of a good pair of dice. What if your dice were not only stylish, but smart? For anyone who’s ever had to deal with playing board games with less than reputable siblings or friends, the electric die just might be your …read more
Fans of MaKey MaKey may find this project similar, but there’s a lot more to the Mini Automat than making music from fruit.
The idea for the Mini Automat (which is an off-shoot of the original Automat project by [Dada Machines]) is to make music accessible to anyone. The device …read more
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 …read more
