Sensirion

Amongst the numerous vendors exhibiting their know-how and products at the Sensors + Test Messe in Nuremberg (D), Sensirion managed to capture all my attention. They not only present very attractive products in terms of: flexibility of interfacing, calibration, size, stability and power consumption, but they present it so well. Here is the type of […]

Vintage Blink

In 1953, Rayteheon delivered the first order for CK722. Introduced by Raytheon in 1953, the CK722 was the first low cost junction transistor available to the general public. Jack Ward reports that “It was an instant success. Countless “build it yourself” articles were published in the popular electronics press and hobbyist magazines. Many of the […]

Extremely Low Frequency Electro Magnetic Field Sensing (Part 2)

Part 1, 2, 3, 4, 5 The proposed application features a few ideas which may be reused for all sorts of applications. As usual, the idea is to build the most exciting Arduino application with the least additional components. In this sense, MicroELFEMF is a serious challenger, as it requires… no additional components! What this application will do is […]

Extremely Low Frequency Electro Magnetic Field Sensing (Part 1)

Part 1, 2, 3, 4 Since almost all modern houses are fitted with AC current we are surrounded by electro magnetic fields. For those who are used to oscilloscopes, you know that the simplest way to illustrate this phenomenom is to approach your finger from the tip of the probe. Thanks to the fast signal sampling functions and to […]

Techno Eco Survey

MathWorks announces built-in Simulink support for Arduino “MathWorks is the leading developer of mathematical computing software. MATLAB, the language of technical computing, is a programming environment for algorithm development, data analysis, visualization, and numeric computation. Simulink is a graphical environment for simulation and Model-Based Design of multidomain dynamic and embedded systems. ” http://goo.gl/CiUNc We are […]

Blog Of The day

Balau’s blog happens to fill a gap in the Arduino’s world. I found there a lot of very valuable information, most of them being related to software layers et hardware/software interfaces. This blog is nicely written and may just lack some illistrations… apart from advertisements…

Fast Signal Sampling (Part 12)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 11, 12 I have good news and bad news… Where shall I start? Bad news? The bad news is that I released a new revision of the PlainADC library that you may have to ask for if you want to get advantage […]
