Need to connect simple devices to a computer, like relays, switches, or a small display, but the computer has no parallel port or that port is in use by some other device? Using USB used to mean that you had to develop specific code for a USB-enabled microcontroller, developing a unique driver with lots of […]

When it comes to charitable giving, some countries open their collective wallets more than others. According to a new study in the Journal of Consumer Research, people who live in countries that promote equality in power and wealth are more likely to donate money than those who live in societies that expect and accept inequality.

This DIY Solder Paste dispenser is an easy project to build, so I thought I would share the details a bit with everyone! When possible I like to build my own tools, it makes sense especially when you have most of the parts on hand. There are a lot of tools that are just yak […]

High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study jointly led by Purdue and Cornell universities. The findings could have implications for the evaluation of the environmental impacts from natural gas production.

The article covers how to interface an accelerometer with the atmega32/atmega16. Before proceeding, the user must know the basics of ADC (Analogy to digital converter) of the AVR.An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they […]

International Rectifier introduced the IR3823 SupIRBuck integrated voltage regulator designed for space-constrained, energy efficient netcom, server and storage applications.The IC delivers up to 3A a 3.5×3.5mm package. Efficiencies in excess of 97.5% are obtainable for designs converting power from a 6V input to a 4.8V output. The extremely high initial efficiency allows switching at up […]

The explosive growth of “wireless” systems has led to a simultaneous expansion in the use of RF connectors and their associated cables. These assemblies are increasingly vital links between multiple circuit boards, between antennas and front ends, and between power amplifiers (PAs) and antennas. They are instrumental to the operation of such wireless devices and […]

PORTLAND, Ore. — ST Microelectronics has introduced what it is calling the world’s smallest digital e-compass — a three-axis magnetometer combined with a three-axis accelerometer on a 2x2mm MEMS chip. By saving board space on next-generation mobile devices, this device should enable new ultra-miniature, location-aware applications. Micro-electromechanical systems already provide much of the smarts to […]

(Phys.org) —By attaching short sequences of single-stranded DNA to nanoscale building blocks, researchers can design structures that can effectively build themselves. The building blocks that are meant to connect have complementary DNA sequences on their surfaces, ensuring only the correct pieces bind together as they jostle into one another while suspended in a test tube.
