Things are heating up in the world of nuclear fusion research, with most fundamental issues resolved and an increasing rate of announcements being made regarding commercial fusion power. China’s CNNC is one of the most recent voices here, with their statement that they expect to have commercial nuclear fusion plants online by 2050. Although scarce […]
Talking computers are nothing these days. But in the old days, a computer that could speak was quite the novelty. Many computers from the 1970s and 1980s used an AY-3-8910 chip and [InazumaDenki] has been playing with one of these venerable chips. You can see (and hear) the results in the video below. The chip […]
The loudspeaker on your home entertainment equipment is designed to project audio around the space in which it operates, if it’s not omnidirectional as such it can feel that way as the surroundings reflect the sound to you wherever you are. Making a directional speaker to project sound over a long distance is considerably more […]
While we’d like to think that pandemics and lockdowns are behind us, the reality is that a warming climate and the fast-paced travel of modern life are a perfect storm for nasty viruses. One thing that could help us curb the spread of the next pandemic may already be on your wrist. Researchers at Aalto […]
Shortwave radio has a charm all its own: part history, part mystery, and a whole lot of tech nostalgia. The Hallicrafters S-53A is a prime example of mid-century engineering, but when you get your hands on one, chances are it won’t be in mint condition. Which was exactly the case for this restoration project by […]
We return to [Tom Verbeure] hacking on Symmetricom GPS receivers. This time, the problem’s more complicated, but the solution remains the same – hardware hacking. If you recall, the previous frontier was active antenna voltage compatibility – now, it’s rollover. See, the GPS receiver chip has its internal rollover date set to 18th of September […]
[Pete] had a friend who would powder coat metal parts for him, but when he needed 16 metal parts coated, he decided he needed to develop a way to do it himself. Some research turned up the fluid bed method and he decided to go that route. He 3D printed a holder and you can […]
Image by [Sasha K.] via reddit Remember that lovely Hacktric centerfold from a couple Keebins ago with the Selectric keycaps? Yeah you do. Well, so does [Sasha K.], who saw the original reddit post and got inspired. [Sasha K.] has more than one IBM Selectric lying around, which is a nice problem to have, and […]
We love camera hacking here at Hackaday, and it’s always fascinating to see new things being done in photography. Something rather special has come our way from [Camerdactyl], who hasn’t merely made a camera, instead he’s created an entirely new analogue film format. Move over 35mm and 120, here’s the RA-4 cartridge! RA-4 is the […]
Long before the first airplanes took to the skies, humans had already overcome gravity with the help of airships. Starting with crude hot air balloons, the 18th century saw the development of more practical dirigible airships, including hydrogen gas balloons. On 7 January 1785, French inventor, and pioneer of gas balloon flight Jean-Pierre Blanchard would […]
