Last Friday Github saw a supply chain attack hidden in a popular Github Action. To understand this, we have to quickly cover Continuous Integration (CI) and Github Actions. CI essentially means automatic builds of a project. Time to make a release? CI run. A commit was pushed? CI run. For some projects, even pull requests […]
For most of history, the world got along fine without the rare earth elements. We knew they existed, we knew they weren’t really all that rare, and we really didn’t have much use for them — until we discovered just how useful they are and made ourselves absolutely dependent on them, to the point where […]
If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic explores boosting common mode rejection by swapping out the old-school tail resistor for a current mirror. Yes, the humble current […]

There’s something magical about the clunk of a heavy 1950s portable radio – the solid thunk of Bakelite, the warm hum of tubes glowing to life. This is exactly why [Ken’s Lab] took on the restoration of a Philco 52-664, a portable AC/DC radio originally sold for $45 in 1953 (a small fortune back then!). […]
If you’ve ever fancied building a ZX Spectrum clone without hunting down ancient ULAs or soldering your way through 60+ chips, [Alex J. Lowry] has just dropped an exciting build. He has recreated the Leningrad-1, a Soviet-built Spectrum clone from 1988, with a refreshingly low component count: 44 off-the-shelf ICs, as he wrote us. That’s […]
The fine researchers at Google have released the juicy details on EntrySign, the AMD Zen microcode issue we first covered about a month ago. And to give away the punchline: cryptography is hard. It’s hard in lots of ways, but the AMD problem here is all about keeping track of the guarantees provided by cryptographic […]
