This Chip Stores No Music. It Still Gets the Same Song Every Time
Phillip Torrone maps a Baochip-1x's 64-bit factory UID into a deterministic composition. Same silicon identity, same piece, with no account, cloud service or generative model.

This box modernizes a bench supply without opening it
PSU-EXT sits between a bench supply and the circuit under test, adding measurement, protection, SCPI and automation. Its manufacturing files are already public even though the product is still in pre-launch.
LG’s real OLED breakthrough is a full sheet of glass
FLiPP replaces the metal stencil used for RGB OLEDs with photolithography. That idea already exists elsewhere; LG’s more interesting claim is applying it to a full Gen 8.5 mother glass.
Reading a radio directly from silicon
Ken Shirriff reconstructed the Philips TDA7000 from a photograph of its die. His method turns patterns in silicon into transistors, then into a schematic, one functional block at a time.
This Motorola 68000 drives PCI cards. All the work is in the translator
A Motorola 68000 can drive real PCI cards, but only because an FPGA translates timing, byte order, addressing and interrupts between two incompatible buses.
He makes one PCB a year. That's exactly often enough to forget the workflow
Kevin Lynagh is not automating PCB design. His KiCad helpers automate the awkward moment when he has to remember how his entire workflow worked last time.
This drone hits the ice so it can stop flying
Ice Dart is not designed to hover above an iceberg. It absorbs impact, drives eight spines into the ice and uses reverse thrust to become a fixed sensor on slopes approaching 60 degrees.
To control an excavator, MIT built a miniature one
Two joysticks force an operator to translate intent into four machine joints. MIT's World-Space Interface copies the excavator geometry so software can perform that translation instead.
2,000× smaller? Only if you count volume
MIT carves empty space into a swollen hydrogel, then shrinks it. The 2,000× figure is volume; roughly 13× linear shrinkage pushes features below 100 nm.
RSGS: repairing satellites where no technician can go
Northrop Grumman's Mission Robotic Vehicle is headed to geostationary orbit carrying dual robotic arms that can inspect, service and extend satellites never designed to be repaired.
