For some people (e.g. this author) solder wick is a tool of last resort. Unfortunately, solder suckers and vacuum pumps lose most of their utility when you move from through-hole …read more Continue reading Making solder wick less painful
It would be hard to find any electronics still in production which use CRT displays, but for some inscrutable reason it’s easy to find cheap 4-inch CRTs on AliExpress. Not …read more Continue reading A CRT Display for Retro Weather Forecasting
It’s not often that we can include an operating system in a Hackaday article, but here’s the full 46-byte source of [Philippe Brochard]’s 10biForthOS in 8086 opcodes: 50b8 8e00 31d8 …read more Continue reading A Forth OS in 46 Bytes
It’s hard to imagine now, but in the mid-1980s, the Internet came close to collapsing due to the number of users congesting its networks. Computers would request packets as quickly …read more Continue reading A Quick Introduction to TCP Congestion Control
When we hear about flash drives in the context of cybersecurity, we tend to think of them more as threats than as targets. When you’re using flash drives to store …read more Continue reading A Presence-sensing drive for Securely Storing Secrets
When we hear the words “pitot tube,” we tend to think more of airplanes than of air ducts, but [Franci Kopač]’s guide to pitot tubes for makers shows that they …read more Continue reading Using pitot tubes for more than aircraft
[ProjectsInFlight] has been on a mission to make his own semiconductors for about a year now, and recently shared a major step toward that goal: homemade spin-on dopants. Doping semiconductors …read more Continue reading Designing A Hobbyist’s Semiconductor Dopant
Almost all satellites have some kind of thrusters aboard, but they tend to use them as little as possible to conserve chemical fuel. Reaction wheels are one way to make …read more Continue reading Magnetohydrodynamic Motors to Spin Satellites
If you want to convert heat into electrical power, it’s hard to find a simpler method than a thermoelectric generator. The Seebeck effect means that the junction of two dissimilar …read more Continue reading Home-casting Thermoelectric Alloys
We’ve seen quite a few delta 3D printers, and a good number of toolchanging printers, but not many that combine both worlds. Fortunately, [Ben Wolpert]’s project fills that gap with …read more Continue reading A Toolchanging Delta 3D printer
