You have a tiny twenty-year-old hard drive with a weird interface. How do you read it? If you’re [Will Whang], by reverse engineering, and building an interface board. In many …read more Continue reading Reading the World’s Smallest Hard Drive
Building a battery pack from 18650 cells traditionally requires patience, a spot welder, and a supply of nickel strip. But what if there was another way? [Ben] is here with …read more Continue reading Modular 18650 Packs, No Spot Welding Required
It seems that for as long as there have been readily available 3D printers, there have been moral panics about their being used to print firearms. The latest surrounds a …read more Continue reading Hacking The System In A Moral Panic: We Need To Talk
Did you ever wonder how the mechanical voltage regulator — that big black box wired up to the generator on a car from the ’60s or before — worked? [Jonelsonster] …read more Continue reading A Voltage Regulator Before Electronics
The physicist William Shockley is perhaps today best known for three things: his role in the invention of the transistor, his calamitous management of Shockley Semiconductor which led to a …read more Continue reading The Shockley 4-Layer Diode In 2026
ArcaOS is an operating system you might not have heard of, but you will recognize it when we tell you that it’s the direct descendant of IBM’s OS/2. It’s just …read more Continue reading OS/2 Never Went Away. Its Successor Has Received An Update
