A good retrofit starts by leaving control alone
Edge Link shows how to add telemetry, a UNS and local AI to old equipment. Its current prototype is mostly upstream: remote control is exactly the part that should not be treated casually.
One bit was enough to start a pump
Motorola’s MC14500B was not an eight-bit computer with seven bits amputated. A one-bit result register matched the questions industrial control kept asking: switch closed, timer done, motor on or off.
You put your phone down. It keeps talking
LEAK turns a phone’s network traffic into light and sound. The crucial detail is that the sculpture does not detect the act of putting the phone down: it becomes the phone’s route to the internet.
He set out to make one sculpture a day. Missing four is the interesting part
Damien Hoar de Galvan set out to make a sculpture every day in 2024. He finished 362 across 366 days, enough for scraps, delayed ideas and a short deadline to become a method.
This 8.8 kg lamp entrusts its light to paper
At Maison Cédrat, clay carries the load, washi diffuses the light, and a set of quiet interfaces lets the shade move or be replaced. The interesting part sits between the materials.
PicoCamera can see 1600×1200. Its RAM sees rather less
PicoCamera brings OV2640, OV3660 and OV7670 capture to RP2040/RP2350. For raw images, though, the real ceiling is not the sensor but the framebuffer.
This Casio hosts a BBS. The network lives somewhere else
A Casio VX-4 runs a BBS in BASIC while a Pi Zero W supplies its Internet connection. The arrangement forces a precise question: what does it mean to host a server?
This DIYPod is called Shuffle. It brought back the screen, menus and even three games
DIYPod Shuffle starts from a simple local music player, then adds an OLED, menus and three games. Its repository shows how quickly a deliberate constraint can turn back into a platform.
The Ploopy A+ keeps its old bearing mount. That is almost good news
The new Ploopy A+ keeps the Adept bearing mount. That is awkward given complaints about the bearings, but it also preserves replacement parts and community mods.
