(Phys.org) —A pair of researchers, Pascal Audet and Roland Burgmann of the Universities of Ottawa and California, respectively, has found a connection between the amount of silica rich quartz above subduction zones and the frequency rate of “slow” earthquakes. In their paper published in the journal Nature, the two describe how they measured quartz amounts in the Cascadia subduction zone using seismic waves, and how it relates to slow earthquakes.

Project Summary: The Tinusaur is a small board with a ATtiny85 micro-controller on it. The board has the minimum required components for the micro-controller to work properly. It also has few headers to connect external components and connector for ISP programmer. The board could work with any of those DIP-8 chips such as ATtiny25/ATtiny45/ATtiny85, ATtiny13 […]

Until recenty my desktop computer has always shared a room with a Hi-Fi setup so there has never been a need for using decent speakers with the computer. When the desktop computer was moved into it’s own room (with no HiFi) I quickly realized that good speakers were now required for decent quality music playback. […]

The circuit in Figure 1 lets you switch high-voltage power to a grounded load with a low-voltage control signal. The circuit also functions as a submicrosecond circuit breaker that protects the power source against load faults. Power switches to the load when you apply a logic-level signal to the output control terminal. circuitWhen the signal […]

Light-fingered chimpanzees are changing the way subsistence farmers make a living in Africa by causing them to grow different crops and spend more time guarding their goods. This is according to work performed by researchers from Trinity College Dublin’s School of Geography, who say that communities near the edge of tropical forests are experiencing a lack of ‘dietary diversity’ and an increased exposure to disease-carrying insects as a result.

The STM32F429 Discovery helps you to discover the high-performance microcontrollers of the STM32 F4 series and to develop your applications easily. It offers everything required for beginners and experienced users to get started quickly. Based on the STM32F429ZIT6, it includes an ST-LINK/V2 embedded debug tool, a 2.4″ QVGA TFT LCD, an external SDRAM of 64 […]

(Phys.org) —Genetic engineering is one of the great achievements of modern science, allowing for the insertion or deletion of genes in order to control an organism’s characteristics and behaviors. However, genetic engineering has its drawbacks, including the difficulties involved in engineering living systems and the potential long-term consequences of altering ecosystems with engineered organisms.

With a height of only 4.5 mm are new terminal blocks able to connect LED modules and LED panels aesthetically and with a maximal reliability. There are numerous SMT connectors on the market, which are suitable for usage on LED panels but even in other applications. That´s why it´s a logic question – why just […]

Beneath the barren whiteness of Greenland, a mysterious world has popped into view. Using ice-penetrating radar, researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as the island of Manhattan at the very bottom of the ice sheet, apparently formed as water beneath the ice refreezes and warps the surrounding ice upwards.

My most rewarding projects are the ones which i actually use. I like my audio gear so, this was the perfect companion project! On my desk i have a headphone amplifier for my AKG K702’s headphones, below it i have my self built Onixia integrated amplifier for my bookshelf speakers. I have been thinking about making a […]
