Geiger Counter - Radiation Sensor Board for Arduino Contents Go to IndexManifesto The main finality of the Radiation Sensor Board for Arduino is to help people in Japan to measure the levels of radiation in their everyday life after the unfortunate earthquake and tsunami struck Japan in March 2011 and cause the nuclear radiation leakages in Fukushima. We want to give the chance to measure by themselves this levels instead of trusting in the general advises which are being broadcasted. The usage of this sensor board along with the affordable and easy to use Arduino platform helps people to get radiation values from specific places. As technical guys, we feel the responsibility of providing our support in those areas where we can contribute. The design of the board is open hardware and the source code is released under GPL. The Libelium Team. Go to IndexThe Board The radiation board has two main parts, the power circuit and the signal circuit . Radiation Sensor Board with the SBM-20 Geiger Tube Connecting the Radiation board to Arduino It means:
NRF24L01-2.4GHz-HowTo Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:Remote sensors for temperature, pressure, alarms, much moreRobot control and monitoring from 50 feet to 2000 feet distancesRemote control and monitoring of nearby or neighborhood buildingsAutonomous vehicles of all kinds These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip. (Details) The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The low-power short-range (200 feet or so)Transceiver is available on a board with Arduino interface and built-in Antenna for less than $3! See it here. NOTE! Power Problems: Many users have had trouble getting the nRF24L01 modules to work. Range?? More Information on these pages:
nRF24L01 Six Channels To One Receiver | ITead Studio As we mentioned before , IBOX can run various versions of operating systems, including linux and android , etc. Some guys are wondering about the differences between the operating system of FLASH version and SD card version, thus we’d like to give a simple reply here : Whether it is linux or Android, NAND FLASH version and the SD card version only differ in the installation position: one is installed in the NAND FLASH and another is installed in a Micro-SD card. At present, IBOX boot sequence gives priority to SD card, if there is an SD card and a system that can run on the SD card , it will boot directly from the SD card. Here, the vedio shows booting into the system with a few different versions of Linux and Android. We would like to thank Santyago , who offers Sunflower Linux 1.0 Beta system for Iteaduio Plus A10 users. For more information, please click HERE.
cours électricité LTspice est un logiciel professionnel de simulation des circuits électroniques analogiques, développé par le fabricant de circuits intégrés Linear Technology. LTspice est un logiciel propriétaire mais il est totalement gratuit, et en version illimitée ! LTspice fonctionne sous Windows, et sous Linux avec l'émulateur Wine. Pour télécharger le logiciel LTspice 1) Saisie du schéma : 2) Résultat de la simulation : La simulation donne : I1 = 5,042 02 mA I2 = 7,563 03 mA I3 = 12,605 mA V1 = 1,663 87 V ce qui est parfaitement en accord avec les valeurs théoriques.

Windmeter / Anemometer by Infidigm Overview The Windmeter is an anemometer designed to measure and record wind speed distribution from 0 to 17+ meters per second. It was designed for high reliability, ease of construction, and for a wide environmental range. Data is logged over a period of 30.46 days (1/12 of a year), and then saved for 11 months. The data can be retrieved with a laptop computer any time within the 12 months of logging. Here are examples of Actual Data that the Windmeter generates! Skills Required General Electronic Knowledge SMD Soldering PCB Prototyping (Single layer) General Mechanical Knowledge Wood working / power tool / hand tool usage Mechanics of the Windmeter / Anemometer Description The Windmeter / Anemometer is constructed from common parts and supplies. Assembly Read the entire document before beginning construction. Parts List Tools Needed Here is a list of the major tools that were used to make the mechanical parts of the Windmeter.

System of SD card version cannot work in NAND FLASH, vice versa. At present, IBOX boot sequence gives priority to SD card, if there is an SD card and a system that can run on the SD card , it will boot directly from the SD card.

Les racines du ciel - Romain Gary En fait, je viens de terminer "Les Racines du Ciel", qui parut en 1956 sous le nom de Romain Gary. Et je tiens à déclarer tout de suite combien il m'a été agréable - et poignant - de découvrir ici un grand romancier auprès duquel j'étais jusque là passée peut-être en raison du battage médiatique qui a été fait autour de lui.J'irai même jusqu'à dire qu'il y a, chez Romain Gary, quelque chose du romancier universel. Pour reprendre une expression trop galvaudée de nos jours et devenue parfaitement utopiste, Romain Gary pouvait prétendre au titre de "citoyen du monde."Il était né à Wilnio, dans une Lituanie russifiée, et se définissait lui-même comme "un cosaque un peu tartare mâtiné de juif."
