How to win Rock-paper-scissors every time I admit it. When I first heard there are actual tournaments for Rock-paper-scissors, sanctioned by the World Rock Paper Scissors Society, I laughed. I mean seriously, $50k to the winner of a game that requires no skill whatsoever? Absurd. Boy was I wrong. Rock-paper-scissors isn't just a silly game kids play or a way to decide who has to be the designated driver at parties. Males have a tendency to throw rock on their first try, inexperienced RPS players will subconsciously deliver the item that won previously, and paper is thrown least often, so use it as a surprise.
Simple Solar Circuits Simple Solar Circuits: How to get started adding solar power to your small electronics projects. Use the sun to power small solar and battery powered night lights, garden lights, and decorations for halloween. The first part of a solar circuit is… a device for collecting sunlight. [Before we move onto our first examples, a word of caution: These are small simple circuits. Direct Drive: The most obvious way to use power from a solar panel is to connect your load directly to the output leads of the solar panel. Here are a couple of examples of this in practice: On the left, we’ve hooked up one of our little solar panels directly to a small motor taken from an old CD player. Interruption-resistant direct drive: The “direct drive” circuits work well for their design function, but are rather basic. Instead of adding a single supercapacitor, you might notice that we’ve actually added two. Adding a battery In this circuit the solar panel charges up a 3-cell NiMH battery (3.6 V).

Shilajit is unproven yet touted as a panacea for many ills It has a smoky, bitter taste, a deeply unpleasant odor and bears a close resemblance to black gobs of tar. Pricey tar, mind you: 10 grams (a month's supply) will set you back $80. The substance, called shilajit, is an ancient ayurvedic medicine. What exactly is this stuff? Helf is quick to distance his water-purified product from processed shilajit capsules manufactured by Dabur India Ltd. that were banned in Canada in 2005 after authorities there found heavy metal contamination. Scientific analysis shows shilajit contains more than 85 minerals and fulvic acid, an antioxidant heavily touted these days by supplement marketers. Dr. Many of those studies were poorly controlled or involved unreasonable doses, though, and good human studies are thin on the ground. health@latimes.com
Basic Electronics Parts List: 2N3904 PNP transistor 2N3906 NPN transistor 47 ohm - 1/4 Watt resistor 1K ohm - 1/4 Watt resistor 470K ohm - 1/4 Watt resistor 10uF electrolytic capacitor 0.01uF ceramic disc capacitor 5mm red LED 3V AA battery holder Optional: 10K ohm - 1/4 Watt resistor 1M potentiometer This next schematic may look daunting, but it is actually rather straight-forward. It is using all of the parts that we have just gone over to automatically blink an LED. Any general purpose NPN or PNP transistors should do for the circuit, but should you want to follow along at home, I am using 293904 (NPN) and 2N3906 (PNP) transistors. For instance, from the datasheet for the 2N3904 transistor, I was quickly able to see that pin 1 was the emitter, pin 2 was the base, and pin 3 was the collector. Aside from the transistors, all of the resistors, capacitors, and LED should be straight-forward to connect. After you finish building the circuit and plug in the power, it should blink.
5 Things A Billionaire Can Teach You About Job Hunting By John Sumser Life is good if you are Reid Hoffman. The self-made billionaire was a part of the founding team at PayPal. I'd like to tell you that I've been chumming around with him; that in his jet somewhere over the Pacific on the way to his private island, we bonded. Instead, I have to report that I never met the fellow. The Hoffman-Casnocha team does a really good job at delivering the scary truth. 10 kajillion faceless people in countries you've never heard of are waiting to take your job as soon as you get good at it. Are you scared yet? As scary as it is, he's probably right. Anyone can be an entrepreneur. Actually, the point is more forceful. It's always day one. He stole this from Jeff Bezos. A million people can do your job. This one comes from a long standing billboard on Silicon Valley's Highway 101. Beware of success. Hoffman knows this terrain well. Take risks when others take refuge. Weak links are critical. Next: How To Get A Job: Work For Free Stories from Glassdoor.com
8 Things Everybody Ought to Know About Concentrating “Music helps me concentrate,” Mike said to me glancing briefly over his shoulder. Mike was in his room writing a paper for his U.S. History class. On his desk next to his computer sat crunched Red Bulls, empty Gatorade bottles, some extra pocket change and scattered pieces of paper. In the pocket of his sweat pants rested a blaring iPod with a chord that dangled near the floor, almost touching against his Adidas sandals. Mike made a shift about every thirty seconds between all of the above. Do you know a person like this? The Science Behind Concentration In the above account, Mike’s obviously stuck in a routine that many of us may have found ourselves in, yet in the moment we feel it’s almost an impossible routine to get out of. When we constantly multitask to get things done, we’re not multitasking, we’re rapidly shifting our attention. Phase 1: Blood Rush Alert When Mike decides to start writing his History essay, blood rushes to his anterior prefrontal cortex. Phase 2: Find and Execute
