Collaborate Disseminate
We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable tools for research. But blasting high-energy cathode rays onto metal-coated …read more

Most of our 3D printers lay down molten plastic or use photosensitive resin. But professional printers often use metal powder, laying out a pattern and then sintering it with a laser. [Metal Matters] is trying to homebrew a similar system …read more
Between hot things, sharp things, and spinny things, there’s more than enough danger in the average hacker’s shop to maim and mutilate anyone who fails to respect their power. But somehow lasers don’t seem to earn the same healthy fear, …read more

When it comes to machining, the material that springs to mind is likely to be aluminum, steel, or plastic. We don’t necessarily think of glass as a material suitable for machining, at least not in the chuck-it-up-in-the-lathe sense. But glass is a material that needs to be shaped, too, and …read more

Sometimes the decision to tackle a project or not can boil down to sourcing parts. Not everything is as close as a Digi-Key or Mouser order, and relying on the availability of surplus parts from eBay or other such markets can be difficult. Knowing if and when a substitute will …read more

Radar and LiDAR have been incredibly quick and effective tools for mapping and surveying the Earth’s surface from aircraft and satellites, but while they can deliver accurate readings through cloud and even forest canopy cover, they can’t tell you what… Continue reading Stanford engineers invent a sonar device that works outside the water
Back in September, Sony launched a flagship 4K laser projector capable of putting out 10,000 lumens. Though Epson America’s latest projector can’t match the resolution, the Pro L30000UNL is a much brighter prospect.Continue ReadingCategory: Home Entert… Continue reading Epson releases its brightest laser projector so far
[DIY3DTech] likes using his Ortur laser cutter for balsa wood and decided to add an air assist system to it. Some people told him it wasn’t worth the trouble, so in the video below, he compares the results of cutting both with and without the air assist.
The air assist …read more

Lightning strikes are a major trigger for wildfires, including the record-breaking blazes that devastated Australia, California and other regions this year. An international research team has now demonstrated a method that could effectively control whe… Continue reading Graphene tractor beams could one day redirect lightning strikes
From the sound of reports in the press, graphene is the miracle material that will cure all the world’s ills. It’ll make batteries better, supercharge solar panels, and revolutionize medicine. While a lot of applications for the carbon monolayer are actually out in the market already, there’s still a long …read more
