This project measures the background radiation outside the house, and transmits it to a display station inside the house. The outside sensing unit is solar powered (but it doesn’t have to be), and should have a range of at least 50m. The display station inside the house continuously displays the current background, and logs it to an SD

USB has established itself as the new standard for connectivity. That is why USB connectivity has become the “holy grail” of most embedded applications. Well, let me get straight to the point. If you want to start developing projects with USB interface, you want to have the proper development tools. To have the tools that you need, you either

Here’s an SVG image to Eagle polygon importer called svg2poly. It seems like an excellent alternative to the BMP importing plugin included in Eagle default package. [via] Surprisingly often, I find myself wanting to import vector images into eagle, and have them appear as polygons – usually for silkscreen. Whilst importing vectors as lines

Macroblock MBI5030, 16-ch constant current LED driver with PWM, SPI-like interface, requires external grayscale clock. Known-good source: Kingelectronics, latest datasheets. The problem: you need the chip to figure out if your code actually works. And you also need the LEDs to see what’s going on – if at all. You could use a logic analyzer,

How Does Silicon Photonics Work? Marcos Hung writes: Imagine a world where it takes just one second to download a terabyte of data. Well, thanks to Intel, this possibility might seem nearer than you think. Years of research in silicon photonics have produced the 50G Silicon Photonics Link. The technology uses a combination of lasers and
