An accidental discovery by [3DQue] allows overhangs on FDM printers that seem impossible at first glance. The key is to build the overhang area with concentric arcs. It also helps …read more Continue reading Arc Overhangs Make “Impossible” 3D Prints
[Asianometry] has been learning about gallium nitride semiconductors and shares what he knows in an informative video you can see below. This semiconductor material has a much higher bandgap voltage …read more Continue reading The Gallium Nitride Revolution
Unless you are an audiophile, you likely think of tubes as mostly relegated to people who work on old technology. However, photomultiplier tubes are still useful compared to more modern …read more Continue reading Single Photon Detection with Photomultipliers
[Smbakeryt] needs your help. He bought a 1984-vintage Z8000 coprocessor card for the PC, but the software is missing in action. Apparently, the co-processor — called a Trump Card — …read more Continue reading Z8000 Trump Card Needs Your Help
MIT has been working on very thin solar cells made of a film just a few microns thick. The problem? The cells are so thin that they’re hard to work …read more Continue reading Solar Cell Fabric Makes Anything Solar
What do you get if you cross graphene, hexagonal boron nitride, and tungsten diselenide? Well, according to researchers at Hunan University, you get a field effect transistor that can act …read more Continue reading A Transistor? Memory? Wait, It’s Both!
Robot “dogs” are all the rage lately, but you probably haven’t seen one that can climb up a wall. Researchers in Korea have made one that can, assuming the wall …read more Continue reading Robot Dog has Animal Magnetism
We’ve looked at the TinySA spectrum analyzer in the past. However, the recent Ultra edition offers an increase in range from 800 MHz to 6 GHz. How does it work? …read more Continue reading Say the Magic Word, and the TinySA Goes Ultra
OK, so a Wankel engine doesn’t really use a Dorito as its cylinders, but it sure looks like one. The company has announced it will offer a range extender rotary …read more Continue reading Mazda Patents Spinning Dorito to Extend EV Range
Car makers have been phasing out AM radios in their cars for quite some time. Let’s face it, there isn’t much on AM these days, and electric vehicles have been …read more Continue reading Ask Hackaday: Will your 2030 Car Have AM Radio?
