Fifteen years after the last stable release, C-Kermit 11 ships with more than 1,700 automated tests, IPv6 and a fix for a bug introduced in 1992. A look at forty-five years of a file-transfer protocol.
Dissecting the RP2040 scanvideo library, Kevin went from seventeen VGA pins down to six, enough for the ZX Spectrum palette. And one missing black pixel was enough to dim the whole screen.
SPOKE turns 27 copper pads punched into a circuit board into a MIDI controller. The interesting part: the RP2040 has no touch hardware at all, so detection is a discharge time counted in software.
A 3D-printed tactile skin locates a press to within a few millimeters with sixteen electrodes and not a single discrete sensor. A close reading of the process: recipe, results, blind spots.
Open Source Ecology squeezed its entire machine wiki into a file readable without a network. Seven years later, that 2019 copy is still the newest one anyone can download.
On an airliner or a destroyer, the energy leaking from one antenna to another gets computed before the first weld. On the menu: a cubic cost, a ghost cavity that makes the model lie, and a story starting in 1981.
Xfinity WiFi Motion turns already-installed gateways into motion detectors without cameras. The sensor arrives through software, and a new category of presence data arrives with it.
A basic Elegoo car becomes a face-chasing robot without replacing its motors, shield or chassis. The useful lesson is not AI itself but adding capabilities one layer at a time.
A transmon is large partly because its capacitor spreads electric field through vacuum and substrate. hBN can confine that field between two plates, at the cost of much harder materials and interfaces.
Simple Photogrammetry GUI turns a stack of 3D tools into three buttons. Its 1.4 GB bundles reveal where all that complexity has actually gone.
