With a sprinkling of hardware and software, he was able to get these cheap laser particle sensors working on his Raspberry Pi, and his work was ultimately incorporated upstream into Mycodo.

With one of these sensors, you can add a 2D touch surface to anything. It’s like an invisible laser harp that can also sense distance. The intended purpose is fingertip detection, and that’s ...

"Basic Pneumatic Schematics and Circuit Design" provides an overview of different common pneumatic schematic symbols, including air treatment symbols; pressure, flow, and direction valve symbols; and ...

Description: defined in 4.3 of this document. Purpose: This Standard establishes the following for potentiometric pressure transducers: Uniform minimum specifications for design and performance ...

The high-index-contrast sub-wavelength grating on the left reflects 99.9 percent of light, the same reflectivity as the much thicker distributed Bragg reflectors on the right. Disclaimer: AAAS and ...

Burns School of Medicine), introduced a low-cost, stencil-based method for producing sensors made from laser-induced graphene (LIG), a key material used in wearable sensing platforms. "This ...

“We think that marking barcodes and symbols ... sensors commonly used to measure distances for topological mapping or for 3D scanning. Topographic LiDAR, for example, typically uses a near ...

When drawing circuit diagrams, rather than drawing detailed components, we use simple symbols to represent the different components.

When the first laser and inkjet printers for PCs arrived—in the mid-1980s—each could print only in monochrome, and their respective advantages were obvious. The differences are more nuanced ...

If you need high-quality printing in a snap, a laser printer can produce clean, sharp prints in as little as a few seconds. But, after three weeks of testing each device, not all laser printers ...

As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...
