Collaborate Disseminate
Lightning rods have been used to guide lightning strikes for centuries, but now scientists have demonstrated something a bit more advanced than a humble metal stick. Beaming a high-powered laser into the sky was shown to deflect lightning bolts, which … Continue reading Scientists guide lightning bolts with laser beams for first time
Sadly, the usual CO2-powered suspects in the DIY laser cutter market are woefully incapable of cutting metal. Sure, they’ll cut the heck out of plywood and acrylic, and most will …read more Continue reading DIY Fiber Laser Adds Metal Cutting to the Mix
Researchers at Northwestern Polytechnical University in Xianyang, China, have demonstrated a drone that never needs to land, thanks to a remote charging system that delivers power via an adaptive, target-tracking laser on the ground.Continue ReadingCat… Continue reading Laser-charged Chinese drone can stay in the air indefinitely
Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But …read more Continue reading A White-Light Laser, On the Cheap
Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current semiconductor materials.Continue ReadingCategory: Electron… Continue reading Water-based circuit concept switches much faster than semiconductors
It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about …read more Continue reading Properly Pipe Laser Light Around with Homebrew Fiber Couplings
The videos from [styropyro] are always amusing and informative. However, ironically for him, he is alarmed that many green laser pointers are more powerful than they are supposed to be. …read more Continue reading The World’s Brightest Laser Pointer?
Scientists investigating the potential of a non-invasive laser therapy to improve cognitive function have produced some promising early results. There are important questions still to answer, but the team demonstrated an ability to boost short-term mem… Continue reading Experimental laser therapy offers boost to short-term memory
A small satellite developed by MIT engineers has set a new record for data transmission between a satellite and Earth. The TeraByte InfraRed Delivery (TBIRD) system used a laser to beam huge amounts of data at up to 100 gigabits per second (Gbps).Conti… Continue reading Laser satellite shatters space-to-Earth data transmission speed record
Digital media provides us with a lot of advantages. For something like recording and playing back music, digital copies don’t degrade, they can have arbitrarily high quality, and they can …read more Continue reading I’ve Got Two Turntables and a Laser Engraver
