Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one of the common robotics kits that includes the chassis, wheels, and motors, something like this. You’ll also need a microcontroller (in this case, an Arduino […]
Riesba NC-559-ASM flux being applied. (Credit: Bits und Bolts, YouTube) Flux is one of those things that you cannot really use too much of during soldering, as it is essential for cleaning the surface and keeping oxygen out, but as [Bits und Bolts] recently found, not all flux is made the same. After ordering the […]
Back in the early days of Linux, there were multiple floppy disk distributions. They made handy rescue or tinkering environments, and they packed in a surprising amount of useful stuff. But a version 1.x kernel was not large in today’s context, so how does a floppy Linux fare in 2025? [Action Retro] is here to […]
Although something that’s taken for granted these days, the ability to perform floating-point operations in hardware was, for the longest time, something reserved for people with big wallets. This began to change around the time that Intel released the 8087 FPU coprocessor in 1980, featuring hardware support for floating-point arithmetic at a blistering 50 KFLOPS. […]
Want to visualize radioactive particles? You don’t need a boatload of lab equipment. Just a cloud chamber. And [Curious Scientist] is showing off an improved miniature cloud chamber that is easy to replicate using a 3D printer and common components. The build uses a Peltier module, a CPU cooler, an aluminum plate, thermal paste, and headlight […]
There are a lot of options for local weather stations; most of them, however, are sensors tied to a base station, often requiring an internet connection to access all features. [Vinnie] over at vinthewrench has published his exploration into an off-grid weather station revolving around a Raspberry Pi and an RTL-SDR for communications. The weather […]
3D printers are built for additive manufacturing. However, at heart, they are really just simple CNC motion platforms, and can be readily repurposed to other tasks. As [Arseniy] demonstrates, it’s not that hard to take a cheap 3D printer and turn it into a viable wood engraver. The first attempt involved a simple experiment—heating the […]
In a recent video, [Andrew Zonenberg] takes us through the process of decapsulating a PIC12F683 to take a peak at its CMOS implementation. This is a multipart series with five parts done and more to come. The PIC12F683 is an 8-pin flash-based, 8-bit microcontroller from Microchip. [Andrew] picked the PIC12F683 for decapsulation because back in […]
