Texas Instruments releases new battery saving technology
Posted on: 14 Nov 2013
Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. Young students may just know of TI as producers of their world famous graphing calculators. However, for […]
New DIN rail clips 1427 series can fasten (almost) every enclosure
Posted on: 13 Nov 2013
Company Hammond brings to market quality universal holders enabling to use your device even on a DIN rail. DIN rail has admittedly a lot of advantages and no wonder, that it became a very favourite „platformou“ for not only distribution boxes, but also for various alarms, centrals, and other devices even with a finer electronics. […]
Studying the brain with micro-injectable LEDs
Posted on: 12 Nov 2013
Professor John A. Rodgers has previously taught us what the future has in store by way of flexible, stampable microelectronics that adhere to the surface of human skin. As revolutionary as those devices can be – providing critical health-related information from real-time physiological monitoring of the human body – they are limited in their ability […]
Overheat Detector Alarm
Posted on: 11 Nov 2013
At the heart of this circuit is a precision integrated temperature sensor, LM35 (IC1), which provides an accurate linear and directly proportional output in mV, from 0 to +155 degrees C. Designed to draw a minimal current of its own, the LM35 has very low self heating in still air. Here the output of the […]
From PWM to voltage
Posted on: 10 Nov 2013
The Arduino library has always had an “analogWrite()” function, even though the ATmega doesn’t have any way to generate a varying voltage. So why the name? Well, what most microcontrollers can do is generate a pulse-width modulated signal, also known as PWM. That’s just a fancy way of saying that the microcontroller periodically generates a […]
USB A to micro USB bridge
Posted on: 09 Nov 2013
This is a little project I made recently, I call it USB A to micro USB bridge and it does what the name says: it’s just a bridge between the USB A female connector and the female micro USB. In the middle there is a DIL pin header that allows you to connect or disconnected […]
MIT Researchers Create Terahertz Graphene Chips
Posted on: 08 Nov 2013
PORTLAND, Ore. – Massachusetts Institute of Technology (MIT) researchers have sandwiched high-mobility graphene sheets between two ferroelectric materials, resulting in terahertz (THz) frequency operation that can directly operate on optical signals. MIT predicts that the new material stack will lead to memories that are 10-times denser than today and to electrical devices that can directly […]
Evaluating Different Approaches for Interfacing Touchscreens
Posted on: 07 Nov 2013
This article looks at the latest touchscreen sensor technologies and the wide range of interfaces that the different technologies use. It also evaluates the different approaches for interfacing such sensors for human interfaces from three, four and five wire to USB, covering sensors and interfaces from Atmel, 3M, IR Touch Systems, and NKK Switches. Resistive […]
Twelve tips for using the Rigol DS1052E Oscilloscope
Posted on: 06 Nov 2013
Push the knobs The knobs all have convenient actions if you push them: pushing Vertical Position or Horizontal Position centers the trace vertically or horizontally. Pushing Tigger Level sets it to zero. Pushing Scale sets it to fine adjust mode. Long Memory If you don’t use Long Memory, you’re wasting most of the capacity of […]
Minimal ECG using an Arduino and Xoscillo
Posted on: 05 Nov 2013
To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope. Circuit diagram Here is the scheme, I am using the typical instrumental amplifier(ins amp) and then another op amp to get some more gain. An ins-amp is like an […]
