Robotic mowers are becoming a common sight in some places, enabled by the cost of motors and the needed control electronics being much lower, thanks to the pace of modern engineering. But, in many cases, they still appear to be really rather dumb, little more than a jacked up bump-and-go with a spinning blade. [Clemens […]

The usual approach to radiation detection is the use of a Geiger-Müller tube and its high voltage circuit requirements, but during a quick surf through the internet today, I came across this portable and “accurate looking” solution developed by Stefan Wagner, on EasyEDA. Rather than the Geiger Muller tube and its complex circuitry, the project uses a miniature Silicon PIN

The Sinclair ZX Spectrum was a compact and affordable personal computer when it first launched in 1982 for £125 (the equivalent of £470 or $745 in 2022). Designed to use tape cassettes for storage, it was also relatively easy to obtain media. But computers have gotten a lot smaller and cheaper over the past four decades, and
One important feature of the Pi 3 flavor of the Raspberry Pi is the ability of the Pi to boot from a network server or a USB Mass storage device, rather than the, pretty much standard way of booting from an SD Card. However, while the Pi 4 featured several upgrades both physically and “OS-lly”, it did not have
Flashing your code into an Arduino, an ESP32 or any other modern microcontroller platform is pretty straightforward: connect the device through USB, fire up the appropriate software platform, and press “program”. But those who followed embedded programming classes in the ’80s and ’90s will remember a more complicated procedure that consists of swapping EPROM chips

The AVR DA Family Incorporates Several New Safety Features Together With Integrated Peripheral Touch Controller As the Internet of Things (IoT) delivers greater connectivity for industrial and home applications and as connected vehicles enhance cabin and operational features, higher-performance microcontrollers are required for better real-time control as well as to enable enhanced human machine interface applications. Microchip

As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a Raspberry Pi system. Using these DTOs it’s trivial to set up features like as a soft power-off button, triggering an external power supply and enable

While mobile gaming has largely moved to smartphones these days, the classic Game Boy remains a hugely popular platform for retro enthusiasts, owing in no small part to its enormous library of quality games. The original Game Boy hardware is pretty much bulletproof, but feels a bit outdated today because it lacks modern conveniences like

This year’s Hackaday Prize is off to a roaring start. And that’s fantastic, because this year’s challenge is a particularly important one: reducing mankind’s footprint on the earth through better energy collection, better resource use, and keeping what we’ve already got running a little bit longer. Not only is this going to be the central
