Favorite automotive relay V23084 in a new cloth
Posted on: 17 Dec 2013
A well known reliable PCB relay can be now found in our store in the version V23084-C2002, fully usable in demanding automotive applications. Previous version of widely used relay V23084-C2001 we introduced to you in the article Automotive relay for PCB used by leading world producers. However after many years of production this relay has […]
New simple, inexpensive graphene treatment method could unleash new uses
Posted on: 16 Dec 2013
Graphene, a two-dimensional array of carbon atoms, has shown great promise for a variety of applications, but for many suggested uses the material requires treatments that can be expensive and difficult to apply predictably. Now, a team of researchers at MIT and the University of California at Berkeley has found a simple, inexpensive treatment that may help to unleash the material’s potential.
Shunt regulator monitors battery voltage
Posted on: 16 Dec 2013
A TL431 shunt regulator is a perfect choice for many applications. You can use it as a comparator with hysteresis by taking advantage of its inner voltage reference along with few additional components. You can use this comparator with hysteresis, like a Schmitt trigger, as a simple battery monitor (Figure 1). You calculate the threshold […]
Add charging status to simple lithium-ion charger
Posted on: 15 Dec 2013
Like other simple, single-cell lithium-ion battery chargers, Microchip’s MCP73812 provides no means of indicating the charging status. You can remedy this situation by adding four components (Figure 1). Add one more LED, and you also get a charging-complete indication. This two-LED configuration has the added benefit that one of the LEDs is always on, providing […]
Truly a web game, Monster Madness is unveiled
Posted on: 14 Dec 2013
(Phys.org) —The director of Nom Nom Games, a subsidiary of Trendy Entertainment, has converted the Monster Madness game to the Web using technologies pioneered by Mozilla. Jeremy Stieglitz, Development Director and CTO for Trendy Entertainment, made it quite clear in a video that he regards the move as significant, in that this is a brave new world of direct access to a plugin-free commercial game, using asm.js and Emscripten
Graphene MEMS Outperforms Silicon
Posted on: 14 Dec 2013
Graphene can increase the sensitivity of micro-electro-mechanical system (MEMS) Sensors by up to 100 times, according to researchers at the Swedish KTH (Kungliga Tekniska Högskolan) Royal Institute of Technology in Stockholm. “The advantage of using graphene membranes for piezoresistve Sensors is their extreme thinness,” Frank Niklaus, a professor at KTH, told EE Times. “The […]
Digital Converters Simplify Multisensor Designs
Posted on: 13 Dec 2013
Description The MAX31850/MAX31851 cold-junction compensated, 1-Wire® thermocouple-to-digital converters perform cold-junction compensation and digitize the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The converters resolve temperatures to 0.25°C, allow readings as high as +1768°C and as low as -270°C, and exhibit thermocouple accuracy of 8 LSBs (2°C) for temperatures ranging from […]
With new study, aquatic comb jelly floats into new evolutionary position
Posted on: 12 Dec 2013
In a study that compares the genomes of aquatic life forms, researchers have found evidence to shuffle the branches of the tree of life. For more than a century, scientists thought that complex cell types, like neurons and muscles, evolved only once, after simple animals that lack these cell types branched from the rest of animals on the evolutionary tree
Arduino Waveform Generator Shield
Posted on: 12 Dec 2013
Waveform generators (also called function generators) are useful for testing and debugging circuits. They can be used to test the frequency response of electronic components like op amps and sensors or to characterize and troubleshoot audio effects boxes and pedals. This waveform generator shield is powered by an Arduino. It outputs four waveforms: sine, triangle, […]
Mini Arduino environment monitor
Posted on: 11 Dec 2013
This is an Example of how you can use the Arduino to monitor various environmental parameters And display them on a LCD screen. Note: I Added a Real Time Clock!! To see the steps, added parts and Sketch I added new steps.. Arduino uno R3 or compatible […]
