The rapidly-improving speed and versatility of digital computers has mostly driven analogue computers out of use in modern systems, as has the relative difficulty of programming an analogue computer. There …read more Continue reading Building an Analogue Computer to Simulate Neurons
There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or creating a clear getaway path. Unlike many Hollywood …read more Continue reading Spoofing an Emergency Traffic Preemption Signal
[Diffraction Limited] has been working on a largely 3D-printed micropositioner for some time now, and previously reached a resolution of about 50 nanometers. There was still room for improvement, though, …read more Continue reading Embossing Precision Ball Joints for a Micromanipulator
The construction of a large language model (LLM) depends on many things: banks of GPUs, vast reams of training data, massive amounts of power, and matrix manipulation libraries like Numpy. …read more Continue reading Building a Dependency-Free GPT on a Custom OS
Liquid nitrogen isn’t exactly an everyday material, but it’s acquired conveniently enough to be used in extreme overclocking experiments, classroom demonstrations, chemistry and physics experiments, and a number of other …read more Continue reading Homemade Liquid Oxygen Demonstrates Paramagnetism
There are some clocks, mostly in or around international airports, which have multiple faces to show the time at various cities around the world. Taking more a forward-looking approach is …read more Continue reading Interplanetary Clock Keeps Time Across the Solar System
The ancient question of whether or not it’s possible to construct a circle with the same area as a given square using only a drawing compass and straightedge was finally …read more Continue reading Running Pokémon with a Compass and Straightedge
One of the joys of browsing secondhand shops is the possibility of finding old, perhaps restorable or hackable, electronics at low prices. Admittedly, they usually seem to be old flat-screen …read more Continue reading Reverse Engineering a Dash Robot with Ghidra
For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the …read more Continue reading Harmonic Radar Finds Hidden Electronics
As anyone who extrudes plastic noodles knows, the glass transition temperature of a material is a bit misleading; polymers gradually transition between a glass and a liquid across a range …read more Continue reading A New and Strangely Strong Kind of Plastic
