Many Hackaday readers have an interest in older technologies, and from antique motorcycles to tube radios to retrocomputers, you own, conserve and restore them. Sometimes you do so using new parts because the originals are either unavailable or downright awful, but as you do so are you really restoring the item or creating a composite […]
When [PeterSripol] was a kid, he made a simple sailboat from a scrap piece of 2×4 and some napkin sails. He’s not 8 years old anymore, but he decided he wanted to make another 2X4 sailboat using the skills he’s learned since he was a kid. You’ll have to get past storytime and mice, but […]
We’ve seen a lot of cubic LED creations recently, but this one takes it a bit further. The BouLED is a work-in-progress icosahedric LED display, a globe-like sphere made of 20 flat triangular LED-lit faces. When combined with sensors inside the display, it will be able to stabilize the image. In other words: you can […]
Getting a legged robot to stay upright, especially a quadruped or biped, can be a challenging undertaking. To experiment with different approaches, [James Bruton] built robot dog test platform and is playing with “dynamic compliant simulated springs“, or in other words, using the motors to act as though they were springs and dampers.. When robotic […]
Like many creative individuals who suddenly find themselves parents, [Marta] wanted to make something special for his children to play with. Anybody can just purchase an off-the-shelf electronic toy, but if you’ve got the ability to design one on your own terms, why not do it? But even compared to the fairly high standards set […]
[Ultimate Robotics] has been working on designing and producing an extremely small ECG that can stream data real time. Typical electrocardiogram equipment is bulky: miniaturization doesn’t do much for a hospital where optimizations tend to lean towards, durability, longevity, and ease of use. Usually a bunch of leads are strung between a conductive pad and […]
Named after British inventor James Dyson of cyclonic vacuum cleaner fame, the Dyson Awards are presented annually to current and recent students of engineering, industrial design, and product design, regardless of age. Students from 27 countries work alone or in groups to describe their inventions, which are then judged for their inventiveness, the production feasibility […]
Before you even ask, it’s an open source trackball and you’re gonna like it. Hackaday Editors Mike Szczys and Elliot Williams get down to brass tacks on this week’s hacks. From laying down fatter 3D printer extrusion and tricking your stick welder, to recursive Nintendos and cubic Castlevania, this week’s episode is packed with hacks […]
The funny thing about clocks is that the more intriguing they are to look at, the more precious time is wasted. This steampunk clepsydra is no exception. A clepsydra, or water thief clock is an ancient design that takes many forms. Any clock that uses the inflow or outflow of water to measure time could […]
Our own [Pat Whetman] wrote about a clever technique published by the University of Michigan, where lasers can be used to trigger a home assistant device. It’s an interesting hack, and you should go read it. Borrowing IP Addresses We’ve lived through several IPv4 exhaustion milestones, and the lack of available addresses is really beginning […]
