[ad_1] Synjets provide non-contact haptic feedback Arduino Team — May 23rd, 2024 If the COVID pandemic showed us anything, it is that our public spaces are overflowing with opportunity for germ transmission. In 2019, most people didn’t think twice about touching a gas pump handle or an ATM touchscreen, but it quickly became apparent that […]

[ad_1] Today is another board from a friend, [treble], who wants to convert a Yaesu FRG7700 radio to USB-C PD power. It’s yet another review that I’ve done privately, and then realized I’ve made more than enough changes to it, to the point that others could learn from this review quite a bit. With our […]

[ad_1] [Stephen McNamera] found a schematic for a grid leak radio online and decided to throw together a few tubes on a piece of wood and see how it worked. As you can see in the video below, it works well. The video is a bit light on details, but the web page he found […]

[ad_1] Harness the power and connectivity of your Arduino UNO R4 WiFi with this IoT lamp Arduino Team — May 23rd, 2024 It can be tough to get started with building an Internet of Things (IoT) project from the ground-up, as getting connected, serving a webpage, and managing other devices can all be a challenge […]

[ad_1] For plenty of computer users, the operating system of choice is largely a middleman on the way to the browser, which hosts the tools that are most important. There are even entire operating systems with little more than browser support, under the assumption that everything will be done in the browser eventually. We may […]

[ad_1] As the debate rages on about the value of AI-generated art, [Chris Borge] printed his own version of another technology that’s been the subject of debate about what constitutes real art. Meet the camera lucida. Developed in the early part of the nineteenth century by [William Hyde Wollaston], the camera lucida is a seemingly […]

[ad_1] [Sharad Shankar] repaired a broken TV by swapping out the cracked and malfunctioning image panel for a new one. Now, part-swapping is a great way to repair highly integrated modern electronics like televisions, but the real value here is something else. He documented his fix but the real useful part is his observations and […]

[ad_1] The instrument which probably the greatest number of Hackaday readers own is likely to be the humble digital multimeter. They’re cheap and useful, but they’re single-channel, and difficult to incorporate into a breadboard project. If you’ve ever been vexed by these limitations then [Alun Morris] has just the project for you, in the world’s […]

[ad_1] When [Daniel Eichhorn] designed the Pendrive S3 project, he wanted to use an off-the-shelf USB enclosure but also add a button for the user to start certain actions. Drilling a hole into the enclosure would be an option, but decided a touch sensor on the top of the enclosure would be much more elegant […]

[ad_1] This week Jonathan Bennett and Dan Lynch talk with François Proulx about Poutine, the Open Source security scanner for build pipeline vulnerabilities. This class of vulnerability isn’t as well known as it should be, and threatens to steal secrets, or even allow for supply chain attacks in FLOSS software. Poutine does a scan over […]
