Depending on which type of electric toothbrush you are using, the replaceable brushes may contain an NFC chip that the handle and possibly base station uses to track various details, …read more Continue reading Using a Toothbrush’s NFC chip to Unlock a Computer
One of the struggles with vintage computer systems is that many of the ICs in them have no modern-day version that you can just purchase and drop-in. Creating replacements that …read more Continue reading Drop-in Vintage CPU Replacements with the tranZPUter Project
Doing board level diagnosis on a PCB is hardly black magic, but some PCBs are definitely more daunting than others. The Socket LGA 1851 mainboard that [Fix the Pixel] got …read more Continue reading Fixing a Dead Socket LGA 1851 Mainboard with a Resistor
For most people, just getting any old microcontroller or system on chip (SoC) from our favorite – or cheapest – vendor is more than good enough. But if you’re really …read more Continue reading Baochip-1x: A Mostly-Open, 22nm SoC for High Assurance Applications
It’s become a bit of a platitude to state that products were manufactured better in ‘the olden days’, but as [The Meandrous Engineer] covers in a recent video essay, the …read more Continue reading Why Engineers are Forced to Create Junk Designs
Although combining electronics and 3D-printed structures is fairly common, this usually entails some level of manual assembly. This contrasts strongly with the Print & Place approach demonstrated by [Oliver Child] …read more Continue reading Print & Place: Add Embedded Electronics While FDM Printing
Over the past decades CRISPR, short for “clustered regularly interspaced short palindromic repeats”, has become somewhat of a household name, holding the promise of directly addressing genetic mutations by effectively …read more Continue reading How CRISPR Could Mark Mutated Cancer Cells for Termination
Statistics is one of those fields which people tend to love or hate when they’re confronted with it during their school time. Although incredibly useful and even essential in many …read more Continue reading Simulating and Visualising the Central Limit Theorem
After previously exploring the basics of UDP broadcasting, why IPv4 subnets are an exciting feature that you really want to dive into, as well as the contentious topic of IPv6, …read more Continue reading UDP Broadcasting Meets the More Focused Multicasting
Before transistor-transistor logic (TTL) took over, diode-transistor logic (DTL) was a common sight especially in pre-IC circuits where it was a major improvement over resistor-transistor logic (RTL). That said, it’s …read more Continue reading Reverse Engineering a 1960s Diode-Transistor Logic IC
