Germanium. It might sound like just another periodic table entry (number 32, to be exact), but in the world of infrared light, it’s anything but ordinary. A recent video by …read more Continue reading Shining Through: Germanium and Gold Leaf Transparency
As the debate rages on about the value of AI-generated art, [Chris Borge] printed his own version of another technology that’s been the subject of debate about what constitutes real …read more Continue reading Camera Lucida – Drawing Better Like It’s 1807
It shouldn’t be a surprise that the idea of a planetarium originated with an electrical engineer, [Oskar von Miller] from the Deutsches Museum in Munich. According to [Allison Marsh] in …read more Continue reading The History of the World’s First Planetarium
Compared to through-hole construction, inspecting SMD construction is a whole other game. Things you thought were small before are almost invisible now, and making sure solder got where it’s supposed …read more Continue reading Tiny Prisms Let You See What Lies Beneath a BGA Chip
An international research team has sent an astounding amount of data at a nearly incomprehensible speed. It’s the fastest data transmission ever using a single optical fiber and shows just how speedy the process can get using current materials.Continue… Continue reading Blazing bits transmitted 4.5 million times faster than broadband
The displays inside the Apple Vision Pro have 3660 × 3200 pixels per eye, but veteran engineer [Karl Guttag]’s analysis of its subtly blurred optics reminds us that “resolution” doesn’t …read more Continue reading Apple Vision Pro’s Secret to Smooth Visuals? Subtly Substandard Optics
We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although …read more Continue reading An Optical Computer Architecture
An experimental new wearable could allow people such as stroke victims to communicate via subtle hand movements. The device takes the form of a relatively thin patch that is temporarily adhered to the skin on the back of the wrist.Continue ReadingCateg… Continue reading Wrist-worn patch converts hand movements into messages in real time
One of the first logic circuits most of us learn about is the humble flip-flop. They’re easy enough to build with just a couple of NOR or NAND gates, and …read more Continue reading This Unique Flip-Flop Uses Chemistry and Lasers
If you’re worried that [Roman Dvořák]’s spectroscopic analysis of fireworks is going to ruin New Year’s Eve or the Fourth of July, relax — the science of this build only …read more Continue reading Seeing Fireworks in a Different Light
