[ad_1] Like many of us [AnotherMaker] is a fan of the classic Forrest Mims electronics books, specifically, the Engineer’s Mini-Notebook series. They were great sources of inspiration, but at the time, he couldn’t afford to actually build most of the circuits described. Now as an adult, he decided to go through the 555 Timer IC […]

[ad_1] Arguably the greatest strength of the Raspberry Pi is the ecosystem — it’s well-supported by its creators and the aftermarket. At the same time, the proliferation of different boards has made things more complicated over the years. Thankfully, though, the community is always standing by to help fix any problems. [Rastersoft] has stepped up […]

[ad_1] Model rocketry has always taken cues from what’s happening in the world of full-scale rockets, with amateur rocketeers doing their best to incorporate the technologies and methods into their creations. That’s not always an easy proposition, though, as this three-year effort to nail a SpaceX-style vertical landing aptly shows. First of all, hats off […]

[ad_1] The smell of resin SLA printing is like the weather — everybody complains about it, but nobody does anything about it. At least until now, as [Aris Alder] tackles the problem with an affordable DIY supplied-air respirator. Now, we know what you’re thinking, anything as critical as breathing is probably best left to the […]

[ad_1] Today’s memory sticks have hundreds of pins and many gigabytes of RAM on board. Decades ago, though, the humble 30-pin SIMM was the state of the art where memory was concerned. If you’ve got vintage gear, you can try and hunt down old RAM, or you can copy [Bits und Bolts] and make your […]

[ad_1] When thinking about loops in programming languages, they often get simplified down to a conditions section and a body, but this belies the dizzying complexity that emerges when considering loop edge cases within the context of static analysis. A paper titled Misconceptions about Loops in C by [Martin Brain] and colleagues as presented to […]

[ad_1] Reverse-engineered schematics are de rigeur around these parts, largely because they’re often the key to very cool hardware hacks. We don’t get to see many mechanical reverse-engineering efforts, though, which is a pity because electronic hacks often literally don’t stand on their own. That’s why these reverse-engineered mechanical diagrams of the Quansheng UV-K5 portable […]

(Credit: Ken Shirriff) Whereas the CPUs and similar ASICs of the 1970s had their transistors laid out manually, with the move from LSI to VLSI, it became […]

[ad_1] Cars have had DRM-like measures for longer than you might think. Go back to the 1990s, and coded cassette decks were a common way to stop thieves being able to use stolen stereos. Sadly, they became useless if you ever lost the code. [Simon] had found a deck in great condition that was locked […]

[ad_1] This rolling ball game brings Skee-Ball-style fun from the arcade to your home Arduino Team — July 9th, 2024 Ask your friends about their favorite games at the arcade and the most common answer will likely be Skee-Ball. But while many other popular arcade games have viable at-home alternatives, Skee-Ball doesn’t — at least […]
