morethanuser.blogspot.com has a guide on how to add a touch screen on a Siglent SDS1022c Oscilloscope. For that purpose he used an Arduino Nano and a touch screen panel from Prestigo 7″ tablet. He discuss about the keyboard protocol, the display driver and the touch screen and shows us how to make it work as an alternative interface for his oscilloscope.

Microchip Technology announced MPLAB Xpress, a new cloud based development environment to provide an easy way to get started with PIC microcontrollers.
Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced its MPLAB® Xpress Cloud-based Integrated Development Environment (IDE). This online development platform is the easiest way to get started with PIC® microcontrollers (MCUs), with zero downloads, sign-in or setup needed to start designing. Microchip’s free, cloud-based IDE brings the most popular features of the award-winning MPLAB X IDE to Internet-connected PCs, laptops or tablets.

The German company Heliatek has developed new OPV multi-junction solar cells with an efficiency of 13.2%. This is a world record for organic solar cells.
Thanks to the excellent low light and high temperature behavior of the organic semiconductor, the electricity generation of the newly developed cells corresponds to the output of conventional solar cells with 16 to 17% efficiency when both are under real world conditions.

Glen Chenier @ edn.com wanted to find out the characteristics of an unknown diode to be able to replace it with an equivalent one so he decided to make some measurements using his test equipment. In this article he show us how to measure the junction capacitance, Cj, and reverse recovery time Trr of a diode using a function generator and a 100Mhz oscilloscope.

This circuit is based on LM2587, a simple boost converter from Texas instruments. It produces a 12V regulated output for a input of 5V. It can also be used as a multiple output regulator, forward converter and as a flyback regulator. This regulator requires minimum number of external components, which makes it cost effective.
Researchers at the University of Wisconsin-Madison have revealed a unique phototransistor that is flexible and faster and more responsive than any similar phototransistor.
The innovative phototransistor could improve the performance of myriad products — ranging from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites — that rely on electronic light sensors. Integrated into a digital camera lens, for example, it could reduce bulkiness and boost both the acquisition speed and quality of video or still photos.

This is an Arduino powered Weather Station Project that can run on batteries for almost a year! In order to achieve that we use a bare ATMEGA328 chip along with some accurate sensors. We use the DHT22 temperature and humidity sensor, a BMP180 barometric pressure sensor, a BH1750 light intensity sensor and a Nokia 5110 LCD display. We use the low power library in order to greatly reduce the power consumption of the project and we disable the lcd display when it is night.

This tutorial will guide you through the process of installing an FTP server on Raspberry Pi. Check it out:
For uploading files on a Raspberry Pi you should install a FTP server. Such a server is very useful if you use your Pi as a web server or even if you want to have a network storage, which can also be accessed outside of your network if an DNS server is installed.
However this tutorial is not only for web server but can also be used for easy file transfer between Raspberry Pi and your PC.

The project designed around L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. L293D Adapter Board can be used as dual DC motor driver or bipolar stepper motor driver. Useful in robotics application, bidirectional DC motor controller and stepper motor driver. Separate logic supply to reduce dissipation. L293D includes the output clamping diodes for protections.
