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 -...

IoE era is here since we are able now to add mobile radio capabilities in our applications! The latest incarnation of the cell phone network will offer internet connectivity and possibilities that could only be dreamt of previously depending on your standpoint, and many more...

Researchers at the Stanford University School of Medicine have developed a way to produce a cheap and reusable diagnostic "lab on a chip" with the help of an ordinary inkjet printer. At a production cost of as little as 1 cent per chip, the new combination of microfluidics, electronics...

Compressed sensing is an new computational technique to extract large amounts of information from a signal. Researchers from Rice University, for example, have built a camera that can generate 2D-images using only a single light sensor (‘pixel’) instead of the millions of pixels in...

The MS2760A is the latest release in the Ultra-portable family of USB driven instruments - it can perform spectrum measurements from 9kHz to 110GHz in the industries smallest and lightest form factor. by Clemens Valens @ elektormagazine.com: There was a time, and not so long ago,...

Nikos Stavrou @ instructables.com build a bi-fuel trip computer using arduino and has a detailed tutorial on it. The computer can measure both LPG and unleaded fuel consumption. He writes: The main reason I made this project is the lack of a trip computer that is designed for LPG...

A small and inexpensive USB-based curve tracer used for troubleshooting electronics in the style of the Huntron Tracker 2000. by Jason Jones: This documents a USB-based curve tracer based on the PIC24FV16KM202, which is a modest 16-bit microcontroller. The board uses a PC screen OR...

circuitbasics.com has a tutorial on how to measure capacitance using arduino. With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial,...
