Building new things in an existing city is hard. Usually, new development means tearing down existing structures. Doing so for apartment complexes or new skyscrapers is one thing, but infrastructure is much more complicated, both from an engineering perspective and an economical one. Not only do people not want to foot the tax bill for […]
Once upon a time, most things were single-purpose, like the pocket watch. Then somebody made a watch with a date function, and next thing you know, we had TV/VCR combos and Swiss army knives. Now, people pull computers out of their pockets just to check the time or the bed temperature of their RepRap. [Owen]’s […]
When it comes to safes, mechanical design and physical layout are just as important as the electronic bits. If care isn’t taken, one element can undermine the other. That appears to be the case with this Amazon Basics branded biometric pistol safe. Because of the mechanical design, the fingerprint sensor can be overridden with nothing […]
Whether you’re getting ready for work in the morning, or heading out on a camping trip in the woods, it’s nice to know what to expect when the weather rolls over the horizon. To keep abreast of things, [natethecoder] built a lamp system to stay across weather alerts. A Raspberry Pi 3 acts as the […]
We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look at the very nice animations from [Learn Engineering] below. The video starts with a little history. Then it […]
If you’re looking for a fancy LED lamp, the Internet can provide in spades. There are all manner of flashy-this and glowing-that, often with wild and impressive designs made with high-end tools. However, when it came time to decorate the apartment, [thebigpotatoe] wanted to build something simple that anyone could attempt. From this, the Super […]
[Starhawk] is a man with a problem. More accurately, he’s a man whose mother has a problem, but ultimately that ends up being the same thing. Her wide-format Canon printer recently stopped working after better than a decade of reliable service, and he wants to know why. Rather than spend the money on buying a […]
3D printers are great for rapid prototyping, but they’re not usually what you’d call… portable. For [Malte Schrader], that simply wouldn’t do – thus, the X-printer was born! The X-printer is a fused-deposition printer built around a CoreXY design. Its party piece is its folding concertina-style Z-axis, which allows the printer to have a build volume of […]
At the end of August I made the trip to Hebden Bridge to give a talk at OSHCamp 2019, a weekend of interesting stuff in the Yorkshire Dales. Instead of a badge, this event gives each attendee an electronic kit provided by a sponsor, and this year’s one was particularly interesting. The RC2014 Micro is […]
Build something cool and pick up new skills from the workshops at the Hackaday Superconference. But decide right now, workshops will sell out and tickets to the conference itself are nearly gone. You must have a Superconference ticket in order to purchase a workshop ticket; buy one right now if you haven’t already. We think this […]
