Radio waves don’t travel well through water, which is why devices such as ROVS (remotely operated vehicles) have to be linked to their operator via a communications cable. According to a new study, however, solar panels may soon allow for practical und… Continue reading Solar cells used to boost wireless underwater communications
Epson has introduced what’s billed as its most advanced home theater projector to date. The LS12000 combines a new light source with processing algorithms and some nifty pixel-shifting technology to deliver a “zero compromise” 4K image on the wall or s… Continue reading Epson launches its most advanced home theater projector yet
[Electronoobs] built a coil gun and the obvious question is: how fast is the projectile? To answer it, he built a chronograph suitable for timing a bullet. The principle is …read more Continue reading As Fast as a Speeding Bullet
Epson has introduced a bunch of Pro-focused interchangeable lens laser projectors destined to light up large venues such as concert halls, museums and stadiums, including the world’s smallest and lightest 20,000-lumen projectors.Continue ReadingCategor… Continue reading Epson introduces world’s smallest and lightest 20,000-lumen projectors
It’s an age-old riddle: if you have a perfect sphere with a perfectly reflective inner surface, will light bounce around inside it forever? The answer is pretty obvious when you …read more Continue reading Cannonball Mold Makes a Dandy Integrating Sphere for Laser Measurements
The quality of consumer-grade 3D printing has gone way up in recent years. Resin printers, in particular, can produce amazing results and they get less expensive every day. [Squidmar] took …read more Continue reading 3D Printer Showdown: $350 Consumer vs $73,000 Pro Machine
Humanity has been wondering about whether life exists beyond our little backwater planet for so long that we’ve developed a kind of cultural bias as to how the answer to …read more Continue reading SHERLOC and the Search for Life on Mars
The current state of the art of embedded motion sensing is based around micro-electromechanical systems (MEMS) devices. These miracles of microfabrication use tiny silicon structures, configured to detect acceleration and …read more Continue reading Quantum Atomic Interferometer For Precision Motion Sensing
It’s a pity that more electronics enthusiasts haven’t taken the hobby to its ultimate level: making your own semiconductors. There are plenty of good reasons for that: chief among them …read more Continue reading Laser Doping His Way to Homemade Silicon Chips
Those guys at Stanford must be watching a lot of James Bond movies. Their latest invention is a laser that can image an entire room through a keyhole. We imagine …read more Continue reading Laser Sees Through Keyhole
