A Homemade Variable Tuning Capacitor for tuning in your FM stations... Would you like to make this site your homepage? It's fast and easy... Yes, Please make this my home page! Don't show this to me again. A 'Multi-Turn' Homemade Variable Tuning Capacitor... A remarkably simple homebrew device for tuning in your FM stations! From a range of 5pF to 27pF, this multi-turn capacitor can be made using only 6 items... My main interest has always been in FM Transmitters and FM Receivers...and always looking for unique ways of achieving the same end results, by making homemade devices in place of store-bought components. The Radio Shack Special project calls for a typical 6-lead variable tuning capacitor. The above picture is the homemade variable capacitor. This homemade device can be used for the Radio Shack Special Project or the TDA7000 FM Receiver Project or any RF device that would need a variable capacitor. Items needed for the project The machine screw and nuts can be purchased at your local Lowe's Store. Radio Shack sells magnet wire. ...your friend, Patrick
Sleeping in an original bed Art & Design We wouldn't mind having one of these beds as our own. In which one would you like to take a nap? Hard drive platter clock. First thing to do is to take your hard drive and a ruler to the local wood working store. I chose to go there rather then the local Hobby Lobby because their quartz clock movements seem to be a much better quality. The 2nd clock later in this instructable (one with 4 platters), unfortunately, has the lesser quality Hobby Lobby quartz movement. I found that I preferred the 3/4" quartz movement. This gave me the option to put in a 3rd platter which looks pretty nice. The cheaper Hobby Lobby movement was also a 3/4" but it allowed me to put in 4 platters instead of 3. Some examples of the movements I found:Wood Emporium 3/4" quartz movement = $8.50Hobby Lobby 3/4" quartz movement = $4.99 After you get back home put the hour and minute hands on, put the battery in, and hang it on the wall. You can also pick up your clock numbers at the wood working store. To disassemble the hard drive platters I used a T10 Torx bit.
Top 10 Crazy Kitchen Tricks That Speed Up Your Cooking I would like to add that the wider the ring, the easier it seems to be. I had a titanium ring more than twice the width of the one shown in the video and it was easy as hell. My wedding ring (which is about the same size as the one in your linked video) still works, but takes more effort and can hurt if I don't leverage it JUST right. I would also like to echo the sentiments of not using your wedding ring (At least in view of your significant other). The one time I got caught doing it, my wife was PISSED. Yea, definitely the wider the ring the better. I usually just use another bottle of unopened beer.
NASA to fly atomic clock to improve space navigation When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing -- essential to NASA's success on deep-space exploration missions. NASA is preparing to fly a Deep Space Atomic Clock, or DSAC, demonstration that will revolutionize the way we conduct deep-space navigation by enabling a spacecraft to calculate its own timing and navigation data in real time. This one-way navigation technology would improve upon the current two-way system in which information is sent to Earth, requiring a ground team to calculate timing and navigation and then transmit it back to the spacecraft. Ground-based atomic clocks have long been the cornerstone of most space vehicle navigation because they provide root data necessary for precise positioning.

Sweet Potato Ranks Number One In Nutrition - Vegetable Facts According to nutritionists at the Center for Science in the Public Interest (CSPI), the single most important dietary change for most people, including children, would be to replace fatty foods with foods rich in complex carbohydrates, such as sweet potatoes. CSPI ranked the sweet potato number one in nutrition of all vegetables. With a score of 184, the sweet potato outscored the next highest vegetable by more than 100 points. Points were given for content of dietary fiber, naturally occurring sugars and complex carbohydrates, protein, vitamins A and C, iron and calcium. Points were deducted for fat content (especially saturated fat), sodium, cholesterol, added refined sugars and caffeine. The reasons the sweet potato took first place? Sweet potatoes are high in the following: beta-carotene, vitamin A, vitamin B6 and vitamin C; fiber, thiamine, niacin, potassium and copper.

Plasma Rocket Could Travel to Mars in 39 Days (PhysOrg.com) -- Last Wednesday, the Ad Astra Rocket Company tested what is currently the most powerful plasma rocket in the world. As the Webster, Texas, company announced, the VASIMR VX-200 engine ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. The test also marks the first time that a small-scale prototype of the company's VASIMR (Variable Specific Impulse Magnetoplasma Rocket) rocket engine has been demonstrated at full power. "It's the most powerful plasma rocket in the world right now," says Franklin Chang-Diaz, former NASA astronaut and CEO of Ad Astra. But Ad Astra has bigger plans for VASIMR, such as high-speed missions to Mars. Chang-Diaz has been working on the development of the VASIMR concept since 1979, before founding Ad Astra in 2005 to further develop the project.

Marbleized Paintings {Craft Camp} Be prepared for a creative summer with these wonderful crafts for children. Just click the button in the left sidebar for ideas to make your summer fun and full of crafty memories! Hi folks! Jessica here from scrumdilly-do! I am tickled pink & orange to bring you a wee bit o’ summer fun. I’ve worked with a lot of kiddos in my days and have found that open-ended messy fun is generally always a hit. Materials: 2-4 packs unsweetened powdered drink mix 1 can shaving cream 1 cookie sheet or shallow tray 2-4 small bowls for your “paint” 1 cup water paper spoons, chopsticks, and/or eye droppers splat mat 8” wide rectangle cut from box or large index card smock and/or plastic gloves optional Set up your art-space in a mess friendly zone. Pour each of your packs of unsweetened drink mix into its own container. Now it is time to add the “paint”. Gently place a sheet of paper directly on top of the colorful mess and gently pat down. Add a bit more shaving cream and paint for each print.
THIS is why we invest in science. This. Every day — every single day, it seems — I see a note on Twitter, or get email, or hear someone on TV asking why we bother spending so much money on NASA. Billions of dollars! We should be spending that money right here on Earth! This argument is wrong in every conceivable way. Why? Because when we invest in science, when we invest in space, when we invest in exploration, we always, always get far more back in return than we put in. See that picture above? So what, right? Here’s what: using this technology — developed for rockets for NASA, remember — engineers designed a way to pump water more quickly and efficiently for fire suppression. One series of tests using empty houses at Vandenberg Air Force Base compared [this new] system with a 20-gallon-per-minute, 1,400 pound-per-square-inch (psi) discharge capability (at the pump) versus a standard 100-gallon-per-minute, 125 psi standard hand line—the kind that typically takes a few firemen to control.

You May Be Able to Actually Make Yourself Smarter—All It Takes Is Practice I totally agree, but don't think that wikipedia-surfing is a good example, because you search for stuff that you want to know (or maybe easier to understand) while when reading a scrience book f.e. you have to read all the way through the article, even if some parts are harder to understand I tend to agree as well, but I've found that as someone who strives to learn almost to the exclusion of all else in my life, when that learning is severely depressed by any of a variety of factors, I'm encouraged to drink. Maybe dumb people don't 'not care,' but they're just not as capable of learning, and lack to means of acquiring the necessary facilitation to expand their minds. Or, maybe you're right and they don't care. I think, as the years go on, I've come to believe that intelligence levels and opportunities are a lot more situational than I'd once thought. But yes, the desire, the motivation is a key factor in anything.
