[ad_1] If you don’t know Morse code, you probably think of a radio operator using a “key” to send Morse code. These were — and still are — used. They are little more than a switch built to be comfortable in your hand and spring loaded so the switch makes when you push down and […]

[ad_1] [Stefan] from CNC Kitchen explored an unusual approach to a multi-material print by making custom PLA filament with a TPU core to make it super-tough. TPU is a flexible filament whereas PLA is hard almost to the point of being brittle. The combo results in a filament with some unusual properties, inviting some thoughts […]

[ad_1] On our travels round the hardware world we’ve encountered more than one group pursuing the goal of making their own silicon integrated circuits, and indeed we’ve seen [Sam Zeloof] producing some of the first practical home-made devices. But silicon is simply one of many different semiconductor materials, and it’s possible to make working semiconductor […]

[ad_1] It’s often said of us humans that we’re the only “tool-using mammals”. While not exclusive to the hacker community, a bunch of us are also “tool-building mammals” when we have the need or get the free time. I initially wanted to try to draw some distinction between the two modes, but honestly I think […]

[ad_1] When the first Raspberry Pi came out back in 2012 it was groundbreaking because it offered a usable little Linux machine with the proud boast of a $25 dollar price tag. Sure it wasn’t the fastest kid on the block, but there was almost nothing at that price which could do what it did. […]

[ad_1] The Asus ROG Ally is a handheld that, to our pleasant surprise, has attracted a decently sized modding community. Recently, we’ve stumbled upon a Reddit post investigating a somewhat common failure mode of this handheld — the microSD card slot going out of order, where an inserted card fails to be recognized, pretty irritating […]

[ad_1] One thing going slightly viral lately is footage of Disney’s “HoloTile” infinite floor, an experimental sort of 360° treadmill developed by [Lanny Smoot]. But how exactly does it work? Details about that are less common, but [Marques Brownlee] got first-hand experience with HoloTile and has a video all about the details. HoloTile is a […]

[ad_1] Never underestimate how far some flight simulator aficionados will go with their builds. No detail is too small, and every aspect of the look and feel has to accurately reflect the real cockpit. As a case in point, check out these very realistic Korry buttons that [Santi Luib III] built for an Airbus A320 […]

[ad_1] Last year the introduction of  RISC-V support to the Android-specific, Linux-derived Android Common Kernel (ACK) made it seem that before long Android devices might be using SoCs based around the RISC-V ISA, but it would seem that these hopes are now dashed. As reported by Android Authority, with a series of recently accepted patches […]

[ad_1] A common way to visualize that a 3D printer’s extruder motor — which feeds the filament into the hot end — is moving is to attach a small indicator to the exposed end of the motor’s shaft. As the shaft turns, so does the attached indicator. Small movements of the motor are therefore turned […]
