Tom Pearson’s anodising bath ended up designing his furniture
In 10,000 Rivets, the size of an anodising tank becomes a format rule, and the rivets needed afterwards become the visible language of assembly.
OpenMANET trades extreme battery life for a real LAN
OpenMANET uses Wi-Fi HaLow, 802.11s and batman-adv to build an IP network without infrastructure. More bandwidth comes with a very different trade-off from LoRa.
This firmware was not dumped. It was rebuilt from what the CPU read
Matthew Alt reconstructs a firmware image by observing SPI reads during boot. Each transaction reveals an address and bytes, while any region the CPU never requests remains unknown.
They grew 100 images instead of drawing them
For Hundred Pieces, Robocobra Quartet turned one hundred mould cultures into a visual system. The frame was strict. Whatever grew inside it was not.
This titanium cube floats. Its bulk density explains almost nothing
RMIT makes a titanium lattice float while leaving its large cells open. The trick lies inside the hollow struts, and in choosing the right density to count.

Dissecting A Lethal Universal Travel Adapter
A $9 universal adapter bus-bars all its prongs onto one conductor, so plugging in one set makes every other exposed set sit at mains voltage.
Vibe-coded a digit recognition chip (Ken Chang)
Ken Chang admits he cannot write Verilog but let an AI co-write an MNIST digit classifier (64→32→10 MLP, ternary hard-wired weights, no RAM/ROM) heading for a TinyTapeout SKY 26c shuttle on SkyWater 130 nm, with bit-exact cocotb checks against the model.
Show HN: Laser Graffiti
Laser Graffiti brings the Graffiti Research Lab idea back in the browser: a webcam, a projector and a laser pointer are enough to paint on a wall, with homography calibration and a burn mode faked by subtracting light.
Kmart Digicam mod part 2
Mason Mirabito keeps modding his cheap Kmart digicam: the $20 eBay lens turned out to be a Super 8 projector lens, forcing a full redesign of his 3D-printed adapter and a hunt for a way to move the sensor closer to the lens.
Modding a Kmart Digicam to take C mount lenses Part 1
Mason Mirabito opens the Anko JLR-80051 camcorder bought at Kmart and designs a deliberately oversized 3D-printed C-mount adapter, meant to be filed down to the correct flange distance once the lens arrives.
Hacking IKEA Furniture
Michael Green (Green Lightning) built two workbenches by screwing the top of his old desk onto 2×2 KALLAX units through MDF boards and rubber, for ~€130 each against ~€1,000 for custom work, showing how a cheap standard module becomes a constrained, reversible fabrication platform.
