Typography enthusiasts reach a point at which they can recognise a font after seeing only a few letters in the wild, and usually identify its close family if not the font itself. It’s unusual then for a font to leave them completely stumped, but that’s where [Marcin Wichary] found himself. He noticed a font which […]
Most of us see the world in a very narrow band of the EM spectrum. Sure, there are people with a genetic quirk that extends the range a bit into the UV, but it’s a ROYGBIV world for most of us. Unless, of course, you have something like this ESP32 antenna array, which gives you […]
Determining that a cable has a broken conductor is the easy part, but where exactly is the break? In a recent video, [Richard] over at the Learn Electronics Repair channel on YouTube gave two community-suggested methods a shake to track down a break in a proprietary charging cable. The first attempt was to run a mains […]
For those who’ve never bitten the Apple, the PowerMac G4 was a blue-tinted desktop Macintosh offered from 1999 to 2004. At the time, the machines were plenty fast — being advertised as the first “personal supercomputer” when they hit the market. But Father Time is particularly harsh on silicon, so they’re properly archaic by modern […]
With today’s technology, emulating video game consoles from the 90s or before is trivial. A Raspberry Pi and a controller of some sort is perhaps the easiest and simplest way to go to get this job done, but to really impress the masses some extra effort is required. This handheld from [Eli] called the Game […]
Starting a new microcontroller project can be pretty daunting. While you have at least a rough idea of where you want to end up, there are so many ways to get there that you can get locked into “analysis paralysis” and never get the project off the ground. Or arguably worse, you just throw whatever […]
On February 13th of 2023, ARCA of the kilometre cubic neutrino telescope (KM3NeT) detected a neutrino with an estimated energy of about 220 PeV. This event, called KM3-230213A, is the most energetic neutrino ever observed. Although extremely abundant in the universe, neutrinos only weakly interact with matter and thus capturing such an event requires very […]
[Chris Borge] was doing some fine tapping operations, and wanted a better way to position his workpieces. This was critical to avoid breaking taps or damaging parts. To this end, he whipped up a switchable magnetic vice to do the job. The key to the build is that the magnetic field can be switched on […]
