It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This requires an extremely small pattern of alternating high and low-density materials, which [ProjectsInFlight] created in his latest video by depositing […]
We all love combat robotics for its creative problem solving; trying to fit drivetrains and weapon systems in a small and light package is never as simple as it appears to be. When you get to the real lightweights… throw everything you know out the window! [Shoverobotics] saw this as a barrier for getting into […]
As there is no cure for celiac disease, people must stick to a gluten free diet to remain symptom-free. While this has become easier in recent years, scientists have found some promising results in mice for disabling the disease. [via ScienceAlert] Since celiac is an auto-immune disorder, finding ways to alter the immune response to gluten […]
They say that if you let a million monkeys type on a million typewriters, they will eventually write the works of Shakespeare. While not quite the same thing [bbenchoff] (why does that sound familiar?), spent some computing cycles to generate random data and, via heuristics, find valid Atari 2600 “games” in the data. As you […]
This week Jonathan and Aaron chat with Ben Meadors and Garth Vander Houwen about Meshtastic! What’s changed since we talked to them last, where is the project going, and what’s coming next? Listen to find out! https://meshtastic.org/ https://flasher.meshtastic.org/ https://meshtastic.com/ Did you know you can watch the live recording of the show right on our YouTube […]
The original DOOM is famously portable — any computer made within at least the last two decades, including those in printers, heart monitors, passenger vehicles, and routers is almost guaranteed to have a port of the iconic 1993 shooter. The more modern iterations in the series are a little trickier to port, though. Multi-core processors, […]
Magnetic tape storage is something many of us will associate with 8-bit microcomputers or 1960s mainframe computers, but it still has a place in the modern data center for long-term backups. It’s likely not to be the first storage tech that would spring to mind when considering a relay computer, but that’s just what [DiPDoT] […]
What happens when you build the largest machine in the world, but it’s still not big enough? That’s the situation the North American transmission system, the grid that connects power plants to substations and the distribution system, and which by some measures is the largest machine ever constructed, finds itself in right now. After more […]
As common as uranium is in the ground around us, the world’s oceans contain a thousand times more uranium (~4.5 billion tons) than can be mined today. This makes extracting uranium as well as other resources from seawater a very interesting proposition, albeit it one that requires finding a technological solution to not only filter […]
