Boris Landoni @ open-electronics.org documents his UV index detector. It measures solar radiation and visualizes the corresponding value on the integrated display of a miniaturized Arduino, in order to tell us when to expose ourselves to the sun… Open Source UV Index Detector -...

by Gheorghe Plasoianu @ edn.com Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC-Ćuk converter whose positive output voltage can be lesser or greater than the...

Ken Shirriff has written an article on reverse engineering the 76477 “Space Invaders” sound effect chip: Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced...

by Graham Prophet @ eedesignnewseurope.com: Two versions of the PADS software package (by Mentor, now a Siemens business) have been made available through distributor Digi-Key. Positioned as design software for “the aspiring innovator” both the free and the $499 versions include...

by Graham Prophet @ eedesignnewseurope.com: Lattice Semiconductor positions its Embedded Vision Development Kit as the first of its type, that is optimized for mobile-influenced system designs that require flexible, low cost, and low power image processing architectures, by which the...

Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with...

What is Zephyr? Zephyr is a small footprint IoT RTOS (less than 10kB) with no user-space and dynamic allocation which make it suitable to run on resource-constrained platforms. Moreover, it's modular and supports multiple architectures, including ARM, X86,ARC, NIOS-II and...

RimstarOrg published an interesting video on his Youtube channel to demonstrate why In north America you can find 3 holes in the electricity socket; which are hot, neutral and ground. The hot wire goes to a breaker-panel and then to electricity grid and finally to a transformer...
