Designed to unlock protected nRF52 SoCs, Christophel’s tool follows on from a similar exploit discovered for protected STM8 chips.
Developer Aaron Christophel has released a tool to read and write the internal flash of any part in the Nordic Semiconductor nRF52 family — using little more than a low-cost Espressif ESP32 microcontroller.

Trimmer Line from the hardware store resembles 3D printing filament very closely and is often made from tough Nylon. Could this be an option for 3D printing filament? Let me show you if it and how it works and how strong 3D prints from Trimmer Line are!
IMPORTANT: Please make sure to only 3D print trimmer line in well-ventilated areas where you’re not constantly present. As some of you pointed out, some materials that are not primarily intended for 3D printing can release TOXIC FUMES when heated! https://www.instructables.com/Is-3D-P…
Test and diagnose your USB cables with this Arduino-based device.
While USB (Universal Serial Bus) connections are in many ways a huge improvement over the parallel, serial, and specialized ports of old, “universal” is still a bit of an overstatement. With a variety of physical form factors and ever-evolving standards, there’s more to making a proper connection than simply plugging any cable in.
Making things even more complicated, just looking at a USB cable’s form factor isn’t always enough to tell whether it will properly power and transfer data to and from your device. Perhaps a particular Micro cable is only for charging, leaving out the data pins, and thus leaving you frustrated as to why you can’t program a certain board. Or maybe a cable is broken internally. To get to the bottom of these potential connection issues, TechKiwiGadgets has come up with the Arduino Cable Tracer.
More info is available in TechKiwiGadget’s project write-up, along with a wiring chart and Arduino code.
Based on the earlier Neotron 32, the Neotron Pico is an RP2040 home computer straight from the ’80s but compatible with modern cases.
Embedded Rust developer Jonathan Pallant is taking the popular Raspberry Pi Pico microcontroller board in a new direction: a simplified home computer, complete with a motherboard compatible with ATX cases.
Released earlier this year, the RP2040-powered Raspberry Pi Pico has been a stellar success. Despite being designed primarily for embedded microcontroller applications, it’s found a home in a range of unusual projects — like a visual synthesiser, an interactive MicroPython-based computer for your desk, another for your pocket, an emulated BBC Micro, an emulated 80186 PC, and even a Nintendo Entertainment System.
For a university project, Codrin used a Raspberry Pi to create a system that detects unauthorized vehicles.
The United States is a car culture and most Americans have to own a car to commute to work and get around. As a result of that fact, parking lots are everywhere. You don’t just need a parking spot for your car at home, but also at work and every other place you go. In Jackson, Wyoming, for example, there are 27.1 parking spots for every household. Despite that, private parking lots are common and owners need a way to ensure that only authorized vehicles enter the lot. For a university project, Codrin used a Raspberry Pi to create a system that detects unauthorized vehicles.
3D printing is constantly saving my belongings when something goes wrong. It’s just about the handiest hobby around, and in this video I’ll share a bunch of functional prints, as well as show off some exciting new flexible filaments!
Super Mario Kart went on to become a 16-bit classic and one of the best selling Super Nintendo games of all time. But Super Mario Kart’s origins didn’t even start as a Mario game. From an unsucessful two player F-Zero game to one of Nintendo’s longest running franchises, this is the story of how Nintendo failed into Super Mario Kart.
Porting Arduboy to the ATMega4809 and making it run on a Arduino Nano Every.
After learning about the Arduboy challenge, we (team Karooza) decided to join in the fun and port Arduboy to a new microcontroller. In the spirit of staying with true 8 bit gaming we chose the ATMega4809. This relatively new microcontroller is also used in the Arduino Nano Every, making it available to the average maker. For this very reason we also chose the Nano Every as our initial target. Then we designed a PCB which handles battery charging, boosting to 5V and breaking out the buttons, LEDs and piezo speaker. Using slightly off-center pads the Nano (with headers) can plug into the breakout board without needing to solder it (a cool idea we borrowed from the Curiosity Nano board).
How does the Atari 2600 display images to the screen with so little memory dedicated to video graphics? It’s all explained right here.
Ever wondered if a PC could cool itself by… ‘breathing’?
