There are some times when an awesome project comes into your feed, but a language barrier intervenes as you try to follow its creator’s description. [Kanti Sharma]’s laser display appears …read more Continue reading A Laser Display Board Of Your Very Own
While it’s in vogue right now to name fancy new technology after Tesla, the actual inventor had plenty of his own creations that would come to bear his namesake, including …read more Continue reading Tiny Tesla Valves Etched in Glass
A couple months back, [macona] got his hands on a 300 watt Rofin CO2 laser in an unknown condition. Unfortunately, its condition became all too known once he took a …read more Continue reading Repairing a 300W CO2 Laser, One Toasted Part at a Time
We’ll just go ahead and say it right up front: we love teardowns. Ripping into old gear and seeing how engineers solved problems — or didn’t — is endlessly fascinating, …read more Continue reading Digital X-Ray Scanner Teardown Yields Bounty of Engineering Goodies
Remember the pistol controller for the original Atari 2600? No? Perhaps that’s because it never existed. But now that we’re living in the future, adding a pistol to the classic …read more Continue reading Adding a Laser Blaster to Classic Atari 2600 Games with Machine Vision
It’s difficult to tell with our dull human senses, but everything around us is vibrating. Sure it takes more energy to get big objects like bridges and houses humming compared …read more Continue reading With a Big Enough Laser, the World is Your Sensor
We all remember the litany from various math classes we’ve taken, where frustration at a failure to understand a difficult concept bubbles over into the classic, “When am I ever …read more Continue reading JavaScript App Uses Advanced Math to Make PCBs Easier to Etch
Lasers do all sorts of interesting things and — as with so many things — more is better. Korean scientists announced recently they’ve created the most powerful laser beam. 1023 …read more Continue reading The Laser Power Record Has Been Broken
Scientists in South Korea have achieved a major milestone in physics – and one pursued by researchers in the field for decades – by generating a record-breaking ultra-high intensity laser. The pulse intensity of over 1023 W per cm sq is the result of a… Continue reading Scientists generate the highest-intensity laser pulses ever recorded
Scientists at the University of Nottingham have developed a first-of-its-kind imaging sensor designed to be deployed inside the human body to build 3D maps of cellular structures. The prototype device, which combines lasers and sound waves in an optica… Continue reading World-first imaging probe searches for cancer with lasers and sound
