Some time ago I came across a new chip from TI, the HDC1000. It’s a temperature and humidity sensor with I2C interface and requires little to no additional components. It comes in an 8BGA package: we can all agree it’s pretty small. Some of the peculiar characteristics of this chip are that it has a DRDYn pin

PORTLAND, Ore. — A new type of transistor harnesses a new effect–called the quantum spin Hall effect — to create a topological field effect transistor (TFET) according to a Massachusetts Institute of Technology (MIT) researcher who recently moved to the newly formed Department of Materials Science and Engineering at Texas A&M University where the Texas

In this article, we explain the basics surrounding arduino. As the title indicates, this article is for absolute beginners in the world of electronics and for people who are beginning with arduino boards. Arduino is an electronics prototyping platform based on a micro controller. Arduino boards are usually made using Atmel’s Atmega series micro controllers or

A global economy brings many benefits, but it also makes international terrorism extremely difficult to combat. With more goods passing through the world’s shipping terminals and airports than ever before, hunting explosives with large, static detectors or teams of inspectors armed with detecting devices and reagents is a bottleneck that increases the chances of evasion.

illustrates a digitally programmable precision resistance that can serve as a microprocessor-driven power-supply load in custom-designed ATE (automatic-test equipment). An 8-bit current-output DAC, IC1, a DAC08, drives current-to-voltage converter IC2A, which in turn drives the gate of power MOSFET Q1. The device under test connects to J1 and J2. In operation, current from the device
Digitally programmable resistor serves as test load Continue Reading
When the built-in incandescent light source of my venerable Olympus microscope failed after many years of use, I decided to design a reliable modern replacement. A 1-W white LED (SEOUL X42182, 350 mA max, Vf = 3.25 V) was the obvious choice to provide high brightness and full-spectrum light without the heat of incandescent or

This instructable shows you how to make an electrocardiograph and a heart rate monitor. It is intended to be a fun science project only. Of course, it should not serve as a medical purpose. PLEASE NOTE : To avoid any risk of electric shock, only use battery alimentation. Electrodes are theorically isolated from the circuit
