Taking a break from ogling microscopic features in Intel’s semiconductor processors, [Ken Shirriff] is back to instead poking at decidedly macroscopic pluggable modules from the 1948 IBM 604 Electronic Calculator. …read more Continue reading Energizing a Vacuum Tube Flip-Flop Module of the IBM 604
As easy as it is to make a late 1980s-style game console using a modern microcontroller, there’s arguably more fun in doing things the traditional way. This is the challenge …read more Continue reading Making a Retro(ish) Game Console From Scratch
One of the best parts about DIY chemistry and physics projects is that you get to decide how early in the supply chain you want to begin, such as with …read more Continue reading Turning Fruits Into Ethylene and Ethane Refrigerant
We’ve all seen these sensors and modules kicking around, as part of beginner kits, strapped into prototypes and potentially even in products deployed in the field. Yet as [John Teel] …read more Continue reading The Seven Sensors and Breakout Boards to Avoid in a Product
Cycloidal gearboxes are a recurring theme in the hobbyist space due to the performance their promise in a compact package. They are capable of taking in a high-speed input and …read more Continue reading Testing a 3D Printed Cycloidal Gearbox Design
Recently [Drygol] had an Amiga 1000 system over for some repairs as well as maintenance and general TLC. This is a Motorola 68000-based home computer from 1985 that also has …read more Continue reading Casual Repair and Maintenance on an Amiga 1000
Although generally glass isn’t associated with touch-sensitive surfaces, the addition of an ITO (indium tin oxygen) coating adds the exciting property of not only being transparent to the visible light …read more Continue reading Turning Glass Into a Touch-Sensitive Button
The stack effect — also known as the chimney effect — is the basic principle that hot air not only rises, but if guided through a tube, the rising hot …read more Continue reading Using the Chimney Effect to Drop Passively Cooled PC Temperatures
As useful as USB-to-M.2 SSD adapters are, sometimes you come across a bit of a dud. A case in point is the Orico-branded TCM2-C3 that features both an attractive clear …read more Continue reading Fixing a JMicron-Based M.2 USB Enclosure That Stopped Working
Regular expressions (regexes) are an amazingly powerful way to perform operations on collections of e.g. text. Regexss can also be considered to be a programming language, even a Turing complete …read more Continue reading DOOM Using Regular Expressions
