Collaborate Disseminate
[Lucas] over at Cranktown City on YouTube has been very busy lately, but despite current appearances, his latest project is not a welder. Rather, he built a very clever gas …read more Continue reading Clever Gas Mixer Gets Just the Right Blend for Homebrew Laser Tubes
Whether you’re a farmer tending to expansive crops that you depend on for your livelihood or a hobbyist gardener trying to keep your tomatoes in check, weeds can be a time-consuming and relentless problem. Startup Carbon Robotics has wheeled out an aut… Continue reading Autonomous Weeder robot uses lasers to take out 100,000 plants an hour
When one thinks about microscopy, it seems to be mostly qualitative. Looking at a slide teeming with bacteria or protozoans is less about making measurements and more about recognizing features …read more Continue reading 3D-Printed Laser Scanning Confocal Microscope Measures Microns
Play around with optics long enough and sooner or later you’re probably going to want a spectrometer. Optical instruments are famously expensive, though, at least for high-quality units. But a …read more Continue reading Pi-Based Spectrometer Puts the Complexity in the Software
Getting great results from a laser cutter takes a bit of effort to make sure all of the settings are just right. But even then, if the air between the …read more Continue reading Hacking an Air Assist for the Ortur Laser
Scientists at CERN have used lasers to cool down antimatter for the first time. The milestone could help unlock some of the secrets of this weird substance, including why it didn’t annihilate the universe soon after the Big Bang.Continue ReadingCategor… Continue reading CERN scientists cool antimatter with lasers for the first time
When we see a CO2 laser cutter build around these parts, chances are pretty good that the focus will be on the mechatronics end, and that the actual laser will …read more Continue reading Scratch-Built CO2 Laser Tube Kicks Off a Laser Cutter Build
When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are …read more Continue reading How Laser Headlights Work
Heart attacks often occur when plaque deposits break off of blood vessel walls, subsequently blocking arteries that carry oxygen to the heart. A new imaging process could identify those unstable deposits, allowing them to be treated before they rupture… Continue reading Analysis of speckled laser light could help prevent heart attacks
Normally, we think of lasers as pretty complex and fairly intimidating devices: big glass tubes filled with gas, carefully aligned mirrors, cooling water to keep the whole thing from melting …read more Continue reading The Devil is in the Details For This Open Air Laser
