CircuitsArchive - Electronic Circuits Schematics RF Communication Between Microcontrollers – Part I | eXtreme Electronics RF Communication Between Microcontrollers – Part I Jul 07, 2009 Avinash RF 28 In many situations a communication link between to devices becomes essential. IR Communications Used in IrDA, and Remote controls Short Range Requires two devices to be in line of sight. In this tutorial we will learn how to practically implement a wireless link between two MCUs. What is a RF Module ? A RF Module is a small circuit pre built and tested. As you can see they have very low pin count. TX Antenna Vcc (Positive Supply) DATA (Data Input) GND RX Antenna GND GND Vcc (Positive Supply) Vcc (Positive Supply) DATA DATA GND So you just need to apply power and fit an antenna and its ready to work.

Psilocybin, the Drug in 'Magic Mushrooms,' Lifts Mood and Increases Compassion Over the Long Term - - TIME Healthland The psychedelic drug in magic mushrooms may have lasting medical and spiritual benefits, according to new research from Johns Hopkins School of Medicine. The mushroom-derived hallucinogen, called psilocybin, is known to trigger transformative spiritual states, but at high doses it can also result in “bad trips” marked by terror and panic. The trick is to get the dose just right, which the Johns Hopkins researchers report having accomplished. In their study, the Hopkins scientists were able to reliably induce transcendental experiences in volunteers, which offered long-lasting psychological growth and helped people find peace in their lives — without the negative effects. (PHOTOS: Inside Colorado’s Marijuana Industry) “The important point here is that we found the sweet spot where we can optimize the positive persistent effects and avoid some of the fear and anxiety that can occur and can be quite disruptive,” says lead author Roland Griffiths, professor of behavioral biology at Hopkins.

Animal Sleep Most animals have a daily pattern of rest and activity. Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.

AVR projects and AVR Butterfly gcc port by Martin THOMAS G.d.W. SS2010 FHFFM You may like to visit my ARM-Projects page too (projects and information for NXP LPC2000, Atmel AT91SAM7, STmicro STR7, STM32, LMI LM3S and other controllers with an ARM-core). Available Projects and Information (Content) "Last updated" may be just additional information not always a new version of a software-package. AVR Butterfly Application code port to avr-gcc Introduction The AVR Butterfly (ATAVRBFLY) made by ATMEL comes with a preloaded application. For german readers: Der Quellcode der auf dem AVR-Butterfly installierten Applikation wird von ATMEL für den IAR C-Compiler zum Download bereitgestellt. Even if you do not own an AVR Butterfly you may find usefull information in the BF application code for general ATMEL AVR development tasks. From the gcc-port of the application code some methodes how to convert IAR-code to avr-gcc/avr-libc-code can be learned. Butterfly gcc-port history Software 2.Oct.2003 - 4.

Getting Started with the TIVA™ C Series TM4C123G LaunchPad Version 1.22 November 2013 Labs are based on CCS 5.5 and TivaWare 1.1 Preface The intent of this workshop is to be a place where a person with a few C skills and some microcontroller experience can familiarize themself with the Tiva C Series parts, Code Composer Studio, TivaWare for C Series and the process of programming these microcontrollers. If you lack C programming skills, there are many courses on the Internet where you can gain them ... that knowledge can form the basis for a rewarding career. If you are migrating from earlier Stellaris devices, please refer to this document for more information. The labs in this workshop (with the exception of Chapter 15's PWM lab) will also work perfectly well on the Stellaris LM4F120 LaunchPad ... no changes are required. Introduction The Getting Started with the TIVA C Series TM4C123G LaunchPad Workshop is an in-depth, hands-on introduction into Tiva C Series basics including: The workshop labs are constructed using TivaWare™[7].

The 10 best treks in the world These 10 classic treks are for serious walkers. All of them require a sturdy pair of lungs, fit legs and a good amount of preparation. However, if you choose to go on any of these trails then you will be rewarded with experiences that last a lifetime. In no particular order: 1. GR20, France Image by Jean-Baptiste Bellet This demanding 15- day (168km, 104mi) slog through Corsica is legendary for the diversity of landscapes it traverses. 2. Image by funkz This 33km (20mi) ancient trail was laid by the Incas and is currently traversed by thousands each year. 3. Image by Crazy Joe Devola ‘The land of the Dogon people’ is one of Africa’s most breathtaking regions. 4. Image by lampertron Reaching a height of 5,545m (18,193ft) at Kala Pattar, this three-week trek is extremely popular with those who want to be able to say, ‘I’ve been to the base of the world’s highest mountain’. 5. Image by Chandramohan Burly V Fewer folk trek on the Indian side of the world’s greatest mountain range. 6. 7. 8. 9.

you knew i was going to make one. they are all over pinterest....(i still am not signed up for pinterest because i don't have time for one more thing but browsing is fun!) so we made one. i took a box of 64 crayons and took out the blacks and browns.i used another small box and doubled up on the good colors i liked and hot glued them to the top of our canvas. then we turned our blow dryer to hot on high. not long after you set the hair dryer by the crayons they get shiny and then the wax starts to melt! and it dries really quickly too. seriously. what could be happier than this?? GREAT project. loved it today is the first FULL day with ALL my kids in ALL day school.yeah...i am smiling as i type that. it's good. it's quiet. i am rockin' it. removing wallpaper.....making code for craft weekend stuff.....doing my hair....going to lunch..... it's all good. hooray for school!

Military’s robotic pack-mule gets smarter but can’t shake fart noise By Stephen C. WebsterMonday, September 10, 2012 16:33 EDT The U.S. military’s experimental robotic pack-mule has been getting smarter, faster and more agile, but it still sounds like a beast with constant flatulence. Picture the scene. You’re walking through a warzone when suddenly shots ring out. That may someday mean the Marines have arrived. Until then, enjoy this video of the AlphaDog, a robot developed by DARPA meant one day to carry up to 400 pounds of soldiers’ gear. DARPA still wants to add visual and audio recognition.
