Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, and laser-induced chemical liquid phase deposition onto glass. I'm using a ...

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

Laser hair removal is the most permanent solution to getting rid of body hair. However, darker skin is often left out of the laser removal conversation as most of the technology is not advanced enough ...

With winter on the horizon, there’s less pressure to go completely hair-free, yet the season is actually an ideal time to try laser hair removal. With less sun exposure than peak summer, there is a ...

Starfire hub, funded by U.S. DOE, is developing fusion energy solutions, led by LLNL. Artist’s rendering of a diode laser module with beam shaping. The Starfire Hub – an initiative funded by the U.S.

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject #CatLaser ...

James has been writing about technology for years but has loved it since the early 90s. While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser ...
