Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

What if a device the size of a microchip could do the job of ...

A handy addition to your toolbox, the best laser tape measure delivers measurements instantly. Our product testing team tried ...

I'm returning to an old project today to fix it since it got broken during my recent move. This toy I made for my dog is very fun project where an Arduino controls two servos so they can move a laser ...

Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Some projects need no complicated use case to justify their development, and so it was with [Janne]’s BeamInk, which mashes a ...

What did Elliot Williams and Al Williams read on Hackaday last week? Tune in and find out. After a bit of news, [Vik Oliver] chimes in with some deep PLA knowledge. Then the topic changed to ...

With summer right around the corner, you may be considering laser hair removal. This method damages hair follicles to reduce hair growth over time, providing more long-term results than shaving or ...

To overcome this noise limitation, the team drew inspiration from a quantum effect known as “energy-time entanglement”. Instead of generating quantum light, they recreated its key noise-resistant ...

A car rebuild and restoration expert has been trying to buy this truck for the past seven years. He bombarded the owners with messages and Instagram comments until they finally said yes. Now, the new ...

There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...
