The ScanaQuad 200 by Ikalogic is a high-performance 4-channel logic analyzer and digital pattern generator. It is designed to be the best companion of a hobbyist when working on serial protocols like UART, SPI, I2C, 1-Wire, USB, I2S, CAN, LIN, RS232, RS485, and more. With the...

Monitor and log water quality (pH & ORP) and temperature from everywhere. Instead of performing regular checks with tester kits to maintain adequate pH and chloride levels in our (small) swimming pool, I decided to build a project that monitors the water continuously and...

PandwaRF, is a portable low-power RF device that captures, analyses and re-transmits RF signals via an Android device or a Linux PC. It uses Bluetooth (BLE) or USB connection to transmit data in a simple and fast way, comes in the form of a controllable housing from a smartphone or a...

Researchers at UCLA have developed an improved method to detect the presence of DNA biomarkers of disease that is compatible with use outside of a hospital or lab setting. The new technique leverages the sensors and optics of cellphones to read light produced by a new detector dye...

While building an ultra-low power application, sensitive hardware and software validation is required to reach system and long battery life. Testing will need an interaction with the tested parts, like simulating input pins of the target application. These difficulties could be solved...

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...
