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.
Dynamic Tonality Free electronics projects and circuit diagrams (schematics) for hobbyists. Build your own electronic gadgets 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.

IanniX How to build electronic devices on your own Building electrical devices is probably the most inexpensive engineering you can do because most electronic components are very cheap, like less than $1. How to actually build devices on your own isn't taught enough in engineering courses, so here's a quick summary of how to get started making devices like I have on my site. In this page, I kind of assume you're an engineer/scientist of some sort (or studying to be one) and that you've already had a few electrical engineering classes. If you don't know any electrical engineering, you'll obviously need to learn the basics before you can start inventing. A good place to start is the book Make: Electronics , which teaches you theory and practical knowledge of components at the same time. First, get an idea To get an idea for something cool to make, it helps to go to online stores for electronic components (Jameco.com is a good one) and look at the components they have. Also, I really recommend getting a microcontroller, like the Arduino. . .
