For his entry into the 2019 Hackaday Prize, [Marin Vukosav] is working on an ambitious project to create a small GPS tracking device which utilizes Narrowband IoT (NB-IoT) for long range communications. Rather than using a GSM modem which would suck the batteries dry in short order, NB-IoT can theoretically maintain a connection within a […]
Have you ever seen a product in the store and been shocked at what the manufacturer was trying to charge for it? Since you’re reading Hackaday, we can safely assume the answer to that question; building a homebrew version of some commercial product for a fraction of its retail price is practically a rite of […]
A retro game console is a fun all-arounder project. You’ve got electronics, mechanical design, and software considerations. For this year’s Hackaday Prize, is going all in. The Portable Retro Game Console with 7.9-inch Display is a work of art, and everything that a retro console could be. This build is based on the Raspberry Pi […]
Over the last few months we’ve seen an influx of homebrew RC controllers come our way, and we’re certainly not complaining. While the prices of commercial RC transmitters are at an all-time low, and many of them can even run an open source firmware, there’s still nothing quite like building the thing yourself. How else […]
Interviewing to be a full-stack engineer is hard. It’s a lot harder than applying for a junior dev job where you’re asked to traverse a red-black tree on a whiteboard. For the full-stack job, they just give you a pile of 2N2222 transistors. (The first company wasn’t a great fit, and I eventually found a […]
New to this year’s Hackaday Prize is a set of live mentor sessions and you’re invited! Being at the center of a successful product design project means having an intuitive sense in many, many areas; from industrial design and product packaging, to manufacturing and marketing. This is your chance to learn from those experts who […]
Mechanical keyboards with reduced key counts are all the rage these days, but while those streamlined input devices might look cool on your desk, there are times when the traditional number pad or navigation keys are quite handy. Rather than just going without, [Mattia Dal Ben] decided to put together his own mechanical auxiliary input […]
It might not be the kind of thing you’ve given much thought to, but if you’ve ever used a desktop 3D printer, it was almost certainly being controlled by an 8-bit CPU. In fact, the common RAMPS controller is essentially just a motor driver shield for the Arduino Mega. Surely we can do a bit […]
Over on hackaday.io and deep in the Hackaday Prize, a lot of cool people are playing around with the possibilities of putting coils in printed circuit boards. On the face of it, it makes sense: drawing spirals on a PCB gets you an electromagnet. This allows you to do all sorts of crazy things. You […]
What do you do if you want a robot with great mobility? Walking is hard, and wheels are good enough, especially if you use the ‘wheels within wheels’ Mecanum setup. But you need torque, too. That’s what makes this entry into the Hackaday Prize so fantastic. It’s a Mecanum wheel of sorts, with an integrated […]
