Over on the [Behind The Code with Gerry] YouTube channel our hacker [Gerry] shows us how to emulate a 74LS48 BCD-to-7-segment decoder/driver using an Altera CPLD Logic Chip From 1998. This is very much a das blinkenlights kind of project. The goal is to get a 7-segment display to count from 0 to 9, and […]
One of the great things about sharing hacks is that sometimes one person’s work inspires someone else to take it even further. A case in point is [Ivor]’s colorimeter hacking (parts two and three), which started with some relatively simple request spoofing to install non-stock firmware, and expanded from there until he had complete control […]
[Surya Chilukuri] writes in to share JTAGprobe — a fork of the official Raspberry Pi debugprobe firmware that lets you use the low-cost microcontroller development board for JTAG and SWD debugging just by flashing the provided firmware image. We’ve seen similar projects in the past, but they’ve required some additional code running on the computer […]
By now most of us have used a Raspberry Pi at some level or another. As a headless server it’s a great tool because of its price point, and as an interface to the outside world the GPIO pins are incredibly easy to access with a simple Python script. For anyone looking for guidance on […]

New and used units flooded the second-hand market, and for a while you could pick these interesting gadgets up for not much more than the cost […]
