Although crude oil contains a vast diversity of hydrocarbons, a comparatively small number of these make up the bulk of demand for oil. Cracking solves this mismatch: most of the …read more Continue reading Building a Desktop Catalytic Cracker
Although parents and teachers like to point out the deep link between cooking and chemistry, most people don’t deliberately apply any chemical principles beyond acid/base reactions to their recipes. Not …read more Continue reading Optimizing Pancakes from Chemical Principles
Although no longer so common as during the heyday of the RepRap movement, it’s easier than ever to build your own largely-printed 3D printer, with designs such as Voron’s delivering …read more Continue reading 3D Printing a Miniature CoreXY Printer
[Chris Doble] has high ambitions: he’s making his own scanning-electron microscope, and as the first step he’s built a high-vacuum system. This required its own controller to manage the various …read more Continue reading A High-Vacuum Controller for an Eventual Electron Microscope
In 2024, [Jan Roetz] decided to see whether he could 3D print a Benchy – the boat-shaped benchmarking tool used in 3D printer calibration – in less than one minute. …read more Continue reading The Final Steps to a Sub-Minute Benchy
For a certain kind of intricate, highly-detailed manufacturing, there’s really no substitute for a resin 3D printer, and it’s therefore unfortunate that they require so many poisonous chemicals. The resin …read more Continue reading A Fume-Control Cabinet for Resin 3D Printing
One simple screening tool for cognitive impairment is the clock-drawing test (CDT): the patient is provided with a printed circle and asked to draw a clock face with the hands …read more Continue reading A Clock Inspired by Failed Cognitive Tests
In some parts of the world it’s common for cell service providers to sell new phones at a price significantly below market value, with the caveat that these phones are …read more Continue reading Linux on Android Provides Inexpensive, Powerful Computing
There are a surprising number of experiments an amateur nuclear physicist can perform, from making a Geiger counter to fusing hydrogen atoms in a fusor. One project which we haven’t …read more Continue reading A Benchtop Neutron Generator for the Home Reactor
Processor design over the last few decades has moved toward RISC processors that aim to implement a few simple operations very efficiently. For a while, though, the trend was toward …read more Continue reading Just How Bad Was the Intel iAPX432?
