content: This is amusing and educational:http://youtu.be/0Uqf71muwWcIt turns out your brain is mostly a bag of water. And water can help increase the size of an antenna and increase the transmission range. The obvious conclusion is...watch the video and find out!Best quote comes at the end:"I didn't believe it, and the only way of finding out whether something is true is to do the damned experiment! Find out what is reality. Disprove your prejudices!"

content: Heh, that's cool. Not just improving transmission antenna gain by getting closer to a wavelength long, but also demonstrating the far more important principle of investigation by experiment."There is a principle, which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance - that principle is contempt prior to investigation."-- Herbert Spencer, 1820-1903This applies in politics and history, as well as science. Also when investigating an aircraft disappearance, in a very high disinformation-noise environment.I'm not sure, but isn't it a sidetrack that he's talking about water? I'd have thought any conductor would do. His head (and the bottle of water) are just acting as a vertical conductor. Capacitive coupled in the case of the water bottle.I laughed when he said "this is something everyone can try." Well, except for people who choose to drive old, non-computerized cars, like me.First time I've ever come across a downside to that choice. Now I can't test whether it specifically has to be water. Vs any old bit of wire, or better yet a correctly tuned antenna and tank circuit.Ah, excuses. OK, I could borrow one. And the real reason I won't do it is that I'm not curious enough about this to make the effort.

It came with the operator’s manual, service manual and a history of its calibration for $100. I thought it was a wicked deal for a scope, it doesn’t have a crazy high bandwidth but probably more then I will ever need, it came out of the local university's lab when they upgraded everything to digital scopes. Hold out long enough and you may just find a good deal

Sometimes moderation of a forum really makes the difference..An interesting recent development is that there seems to be a bunch of dissatisfied former Slashdot users that have started posting in comp.misc. Which isn't really relevant per se, but maybe some people will spill over and rediscover what newsgroups are about.

content: So in the future i am hopefully going to be making more videos for youtube, i have a GoPro Hero 3+ Black which i bought recently as it can shoot in 240fps. I have used my aged Canon PowerShot A480 for some of my videos but that was just a temporary thing so need a decent camera.I was checking out the cameras in John Lewis on Sunday and had a play with the HC-V720 from Panasonic (£398), seemed to have all the bells and whistles you might need and the menus worked pretty well.http://www.panasonic.com/uk/consumer/cameras-camcorders/camcorders/hd-camcorders/hc-v720eb.htmli invite thoughts and other suggestions...

content: Seems like a good camera for the money.I personally bought a Sony HDR-CX410VE on Black Friday and I'm very satisfied with it:http://www.amazon.co.uk/Sony-CX410-Full-Handycam-Wi-Fi/dp/B00AWME0NY/ref=sr_1_1?ie=UTF8&qid=1394462728&sr=8-1&keywords=cx410veThe Panasonic model may have better low light recording (and night vision) and I like that wireless streaming feature - the Sony camera says it has wireless but in reality that's only with a 60-100 uk pounds adapter you have to buy separately and I'm not even sure it streams video to pc (it advertises streaming to ipad and other such devices).But what I like about the Sony model and why I bought it, is because it has SteadyShot Image Stabilisation done mechanically using servomotors instead of just capturing a larger rectangle and digitally cropping frame by frame to stabilize the image. I can feel that mechanical stabilisation doing its job when I'm recording stuff outside... and there's also a youtube video showing how some people use this camera like a gopro on kites and small planes and bikes. It has digital stabilisation as well, but it can be disabled.Otherwise, it has the same standard battery type they used for a few years on other models, so no problems finding spare batteries or buying a higher capacity one (there's a battery that lets you record for 6-8 hours of hd, the standard one gives you about 1 1/2.. 2 hours of record time), standard sdhc cards, charges from usb or from supplied charger, has micro hdmi out , mic in , stereo out, av out (have to buy cable if you want it)

content: One of the earliest books I can remember reading wasCosmosby Carl Sagan. I read it when I was 8 years old, and though much of it was beyond my understanding at the time, it helped form my understanding and perception of the world. As I entered my early teens I re-read it, and read other books by Sagan, and by Hawking and Feynman. I watched the original Cosmos on VHS. He taught me to seek to explore and understand the universe.Though the winds of fate and chance blew me off the path to becoming a scientist, my beliefs, values, aspirations, and dreams were powerfully shaped by Carl Sagan as I grew up. Without his books and those VHS tapes, I would be a different person than I am today.When I heard that Seth McFarlane was remakingCosmos, I was scared shitless. While I enjoy his comedy, the idea of the creator of Family Guy remaking one of the most important and serious television programs in history, and one that's very important to me, was deeply worrying. Even the inclusion of Neil deGrasse Tyson, who I'm a fan of, wasn't enough to convince me.I just finished watching the first episode.They got it right.If you haven't seen it yet, please watch it as soon as physically possible.

I definitely have lost some of my studying capacities.This is the first Coursera training that I finished. I started Power Electronics last year but had to give up due to several reasons - the most important one that my math is below par at the moment.To deal with that, I started the Calculus One course on Coursera together with the Linear Circuits one, to boost the math.That helps a lot.The Calculus One course is actualy excellent.The linear circuit training covers resistive circuits, Kirchhoff, Thevenin, ... , reactive circuits, analysis of AC in linear circuits, and power calculations in reactive systems.At the end of this training I do feel that my knowledge on the mattrer is back on par.

It was there one minute, gone the next. The ADS-B shows this... doesn't show any kind of descent or unstable/erratic flight, just nothing.Bomb? Sudden structural failure? Massive electrical failure/fire? Botched hijacking?...whatever it was I hope it was quick as I do not want to imagine falling from 33000ft.

Qualcomm's (or your choice of competitor) chips are used in the plane that they were flying on, they must have taken it down to get ahead of the competition!On a serious note, it does suck, you do hope it was quick, but I think it would be pretty hard to get a whole plane to explode at once, I guess the best case for a quick death would be to crash into the ocean. It is a pretty strange situation.Maybe a new Bermuda triangle is forming.Interesting that companies don't let key individuals travel together, never thought of that but it makes sense.

MAybe they lose money but don't mind since it will perhaps make more loyal customers.

content: Probably a 7107 chip then. Easy enough to test, just breadboard the chip in a 7107 application without a display, and check you get a backplane clock out of the BP pin and digit drives out of the digit segment pins For safety use a 5V supply and feed the supply via a 1k resistor to the chip. That way if the pinout is wrong you will not blow it up. You do not have to feed an input at all, just connect the components needed for the clock and integrator, and tie the internal reference in. Short input voltage pins to analogue common. You just want a basic function check that it is working somewhat. If it passes then connect properly with a 9V supply.

I've been using various sources to teach myself including "The Art of Electronics", various electronics websites, youtube videos and forums such as this one. I've also got a book with breadboard projects that I'm working my way through for some practical circuit building experience and to help ground theoretical concepts in practice.Feel free to message me directly or reply here with any questions.
