An interactive-speed Linux computer made of only 3 8-pin chips (dmitry.gr)
There was a time when one could order a kit and assemble a computer at home. It would do just about what a contemporary store-bought computer could do. This time is long gone. Modern computers are made of hundreds of huge complex chips, with no public datasheets, with many hundreds of watts of power supplied to them over complex power delivery topologies.

iMac G4(K) (jcs.org)
A year ago I tried using an M1 iMac for work duty but its 21" screen took up too much room on my desk. After seeing Sean's video on Action Retro about putting an M4 Mac Mini inside an iMac G4, I thought I'd give it a try.

Reviving an old kindle pw7 as an e-ink dashboard (terminalbytes.com)
Most of us have a drawer (or a box) stuffed with old gadgets—a sort of tech graveyard we can’t quite bring ourselves to throw out. You know the one I’m talking about: that chaotic nest of tangled cables, forgotten adapters, and mysterious dongles that looks like a digital snake pit (yeah, exactly like that mess in the photo below).

The Supersonic Trebuchet (hackaday.com)
Have you ever sat down and thought “I wonder if a trebuchet could launch a projectile at supersonic speeds?” Neither have we. That’s what separates [David Eade] from the rest of us. He didn’t just ask the question, he answered it! And he documented the entire build in a YouTube video which you can see below the break.
