Collaborate Disseminate
In the old days — we are talking like the 1960s and 1970s — computers were often built for very specific purposes using either discrete logic or “bit slice” chips. …read more Continue reading Tilting at Windmills Nine Bits at a Time
Once upon a time, making a superconductor required extremely cold temperatures. Scientists understood why superconducting materials could move electrons without loss, but the super cold temperatures were a problem. Then …read more Continue reading Making Light of Superconductors
What hacker doesn’t love a puzzle? We have a doozy for you. According to KUOW — the NPR affiliate in Seattle — they have been getting an unusual complaint. Apparently, …read more Continue reading Ask Hackaday: What’s Going on with Mazdas in Seattle?
Koenigsegg, the Swedish car company, has a history of unusual engineering. The latest innovation is an electric motor developed for its Gemera hybrid vehicle. The relatively tiny motor weighs 63 …read more Continue reading How Can 335 Horses Weigh 63 Pounds?
How many qubits do you need in a quantum computer? Plenty, if you want to anything useful. However, today, we have to settle for a lot fewer than we would …read more Continue reading IBM Eagle Has A Lot of Qubits
Chemical engineers at MIT have pulled off something that was once thought impossible. By polymerizing material in two different directions at once, they have created a polymer that is very …read more Continue reading As Light as Plastic; As Strong as Steel
We keep trying to learn more about quantum computers. But the truth is, the way we program quantum computers — or their simulators — today will probably not have much …read more Continue reading Twist Promises Easier Quantum Programming
[Call Me Swal] wanted to experiment with large 3D prints. So he took a Hornet 3D printer and designed a lot of 3D parts to convert it into an “infinite” …read more Continue reading Conveyor Belt Printer Mod is Nearly All Printed
Researchers at the University of Texas have been experimenting with optical 3D printing using near infrared (NIR) light instead of the more traditional ultraviolet. They claim to have a proof …read more Continue reading 3D Printing Goes Near Infrared
Most of us want our 3D prints to be perfect. But at Cornell University, they’ve been experimenting with deliberately introducing defects into printed titanium. Why? Because using a post-print treatment …read more Continue reading Defective 3D Printing for Great Strength
