[ad_1] Whatever you’re doing with your hand tools, by the US Army’s lights, you’re probably doing it wrong. That seems to be the “Green Machine’s” attitude on pliers and screwdrivers, at least, the main stars of this 1943 War Department training film on the horrors of tool abuse. As kitschy as the film might be, […]

[ad_1] Cheap uninterruptable power supply (UPS) boards that take Li-ion cells of some description seem to have cropped up everywhere the past years. Finding use in applications such as keeping single-board computers ticking along in the case of a power failure, they would seem to be a panacea. Unfortunately most of these boards come with […]

[ad_1] Create your own affordable Arduino-powered smart glasses Arduino Team — May 6th, 2024 When Google Glass launched in 2013, the public opinion seemed to be “interesting technology, but the world isn’t ready yet.” Now that more than a decade has passed, the world may finally be ready — especially with the omission of controversial […]

[ad_1] [IMSAI Guy] wants you to build a non-contact scope probe. The cost? Assuming you have a bit of wire and a regular scope probe, it won’t cost you anything. Why do you want such a thing? You can see what he does with it in the video below. The probe is really just a […]

[ad_1] You have an hour to kill, and you like old communication technology. If you happen to be in Windsor, Connecticut, you could nip over to the Vintage Radio and Communication Museum. If you aren’t in Windsor, you could watch [WG7D’s] video tour, which you can see below. The museum is a volunteer organization and […]

[ad_1] Introducing Opta Expansions: scalable simplicity! Arduino Team — May 6th, 2024 Last year, we launched the Arduino Pro Opta: it was an instant success with our community, and allowed us to reach PLC engineers with a new solution specifically designed for their needs.  To further expand Opta’s capabilities, today the Arduino ecosystem welcomes various […]

[ad_1] Have you ever wanted to take a break from reading or studying to just rock out for a few blissful minutes? If you’re anything like us, you like to rock out most of the time and take the occasional break to do your reading. Either way, you really can’t go wrong with this MIDI […]

[ad_1] It shouldn’t be a surprise that the idea of a planetarium originated with an electrical engineer, [Oskar von Miller] from the Deutsches Museum in Munich. According to [Allison Marsh] in IEEE Spectrum, he thought about the invention in 1912 as a way to demonstrate astronomical principles to the general public. While it seems obvious […]

[ad_1] A good amount of hacks can be done with off-the-shelf hardware – what’s more, it’s usually available all over the world, which means your hacks are easier to build for others, too. Say, you’ve built something around a commonly available portable router, through the magic of open-source software. How do you make the fruits […]

[ad_1] Although most people are probably familiar with the different energy levels that the electron shells of atoms can be in and how electrons shedding excess energy as they return to a lower state emit for example photons, the protons and neutrons in atomic nuclei can also occupy an excited state. This nuclear isomer (metastable) […]
