For his Hackaday Prize entry, [Martin] is building an Open Source Multimeter that can measure voltage, current, and power. It’s an amazing build, and you too can build one yourself. The features for this multimeter consist of voltage mode with a range of +/-6V and +/-60V. There’s a current mode, basically the same as voltage, […]
Back in March, the call went out: take your wiggliest, floppiest, most dimensionally compliant idea, and show us how it would be better if only you could design it around a flexible PCB. We weren’t even looking for a prototype; all we needed was an idea with perhaps a sketch, even one jotted on the […]
We’re on the lookout for the most interesting connected projects, things that communicate wirelessly to do something clever. Show us your creations and you can win the Connected World contest. Chances are you’ve already been automating the world around you with wireless connections. This could be as simple as WiFi, or as convoluted as systems […]
For college-aged engineers and designers, finding a problem they’re truly passionate about early on could very well set the trajectory for an entire career. This is precisely the goal of the Cornell Cup, a competition that tasks applicants with solving a real-world problem in a unique and interesting way. From what we saw this is […]
The 2019 Hackaday Prize, which was announced last week, is very much on everyone’s mind, so much so that we’ve already gotten a great response with a lot of really promising early entries. As much as we love that, the Prize isn’t the only show in town, and we’d be remiss to not call attention […]
What prosthetic limbs can do these days is nothing short of miraculous, and can change the life of an amputee is so many ways. But no matter what advanced sensors and actuators are added to the prosthetic, it has to interface with the wearer’s body, and that can lead to problems. Measuring and mapping the […]
The now-humble PCB was revolutionary when it came along, and the whole ecosystem that evolved around it has been a game changer in electronic design. But the PCB is just so… flat. Planar. Two-dimensional. As useful as it is, it gets a little dull sometimes. Here’s your chance to break out of Flatland and explore […]
There was a time, not so very long ago, when simply getting a 3D printer to squirt out an object that was roughly the intended shape and size of what the user saw on their computer screen was an accomplishment. But like every other technology, the state of the art has moved forward. Today the […]
It may only run for a brief time, and it’s too big for use in an actual wristwatch, but this 3D-printed tourbillon is a great demonstration of the lengths watchmakers will go to to keep mechanical timepieces accurate. For those not familiar with tourbillons, [Kristina Panos] did a great overview of these mechanical marvels. Briefly, […]
Long cables are only neat once – before they’re first unwrapped. Once that little cable tie is taken off, a cable is more likely to end up rats-nested than neatly coiled. Preventing that is the idea behind this 3D-printed cable reel. The cable that [Kevin Balke] wants to make easier to deal with is a […]
