Collaborate Disseminate
We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the …read more Continue reading Did You Know That The Raspberry Pi 4 Has More SPI, I2C, UART Ports?
Sarcasm is notoriously difficult to distinguish in online communities. So much, in fact, that a famous internet rule called Poe’s Law is named after the phenomenon. To adapt, users have …read more Continue reading Turn On Sarcasm With the Flip Of a Switch
Hackers love the warm glow of a vacuum fluorescent display (VFD), and there’s no shortage of dead consumer electronics from which they can be pulled to keep our collective parts …read more Continue reading Reverse Engineering a Topfield VFD Front Panel
Adding an audio channel to your microcontroller project can mean a pile of extra components and a ton of processing power, as a compressed stream must be retrieved and sent …read more Continue reading Digital Audio for Microcontrollers Doesn’t Come Much Simpler Than a WART
One of the main advantages of cheap wireless modules is that they get used in consumer electronics, so if you know what’s being used you can build your own compatible …read more Continue reading Hacking A Solar Inverter RF Interface
As amazing as CircuitPython is, it hasn’t yet been ported to any 8-bit microcontrollers. [Chris Heo] was unsatisfied with his inability to use Python on his 8-bit ATmega4808 AVR, so …read more Continue reading Python Runs Through A Zombified 8-Bit AVR
[Carsten] spent over a year developing a small CPU system, implementing his own minimalist instruction set entirely in TTL logic. The system uses a serial terminal interface for all I/O, …read more Continue reading Minimal UART Computer
The basic test instrument suite — a bench power supply, a good multimeter and perhaps an oscilloscope — is extremely flexible, but not exactly “plug and play” when it comes to diagnosing problems with some common hardware setups. A problem …read more

The streaming box allows arbitrary code execution as root, paving the way to pilfering social-media tokens, passwords, messaging history and more. Continue reading Authentication Bug Opens Android Smart-TV Box to Data Theft
Have you ever wanted to watch someone reverse engineer a piece of hardware and pick up some tips? You can’t be there while [Jeremy] tears open a Netgear N300 router, but you can see his process step by step in some presentation charts, and you’ll get a few ideas for …read more
