Stephen Evanczuk writes: Lithium-ion batteries have emerged as a common energy-storage device in many energy-harvesting applications. For engineers, maximizing battery performance and lifecycle requires use of battery charging circuitry able to account for the specialized characteristics of Li-ion cells
This is an all-digital-hardware Theremin. The Digital IR Theremin uses comparators, digital logic and a single 555 timer for tone generation to make it so that when you wave your hand in front of the infrared proximity sensor, it outputs a tone with varying pitch depending on how far away your hand is from the sensor!

L16 module supports system GPS, but also the Russian GLONASS, thus enabling to use almost a double amount of satellites for a better accuracy and higher accuracy even in urban conditions. Quectel L16 based on Teseo II engine from STMicroelectronics, belongs to first modules supporting both navigation systems

(Phys.org)—Robot research has its own unique show of hands as scientists focus on improving human-like abilities of grasping, pushing, and manipulating objects. Grabbing current attention is an assistant professor at Worcester Polytechnic Institute, Eduardo Torres-Jara, whose MIT spinoff, Robot Rebuilt, is featuring the robot Tactico, whose hand dexterity involves sensitive fingers capable of handling wine glasses and coffee mugs without requiring broom pans and mops in their aftermath.

The UK’s first Raspberry Pi Hack Day has been held, with the winner of “Best Overall Hack” being a virtual board game suitable for educational use within schools. The 24-hour bake-a-thon, hosted by CPC in Leeds, focused on programming solely using the credit card-sized Raspberry Pi, and the winning team – Spooks – developed a board game which encourages players to experiment with programming

igital storage oscilloscopes HAMEG HMO win many awards because of many reasons, which can be summarized into one sentence – an excellent price / performance ratio. Or more in detail – excellent features, user-friendly control and rich equipment with various functions enabling a fast “overview” but even a detailed analysis of measured signals, including math calculations. Inspite of advanced functions Hameg HMO series oscilloscopes maintain a simple intuitive control, thus a user can focus more on the measurement itself, than on a setting of the instrument

XMEGA-A1 Xplain development kit provides a straightforward way to development of applications with Atmel XMEGA microcontrollers. XMEGA a family of powerful 8/16-bit RISC microcontrollers with many built-in peripherials (DMA, RTC, LCD driver, 12 bit ADC,…) is ideally suited for relatively high performance applications, where we will with favor use its features – often without a need to add any other peripherials.

(Phys.org)—Quadrotors that can not only successfully fly in the air but can also roll along on the ground represent the kind of exercise that moves researchers at the Robotics Lab at Illinois Institute of Technology (IIT), which is part of the Mechanical, Materials, and Aerospace Engineering Department. Engineers there have developed a vehicle that indeed can move on land and air.

photo credit: myropcb.com I decided to order a prototype PCB for my latest project in a professional fabrication company but i could’ t decide if i should order it in a company in Europe or Asia. I am located in Europe and I wanted fast and quality service so it seemed that ordering from Europe will be the best choice.
