DIY Science Hacks: Faraday Cage Phone Pouch. This Faraday Cage phone pouch blocks all radio signals coming in or out of your cellphone.
Material costs are about $10, it takes ~ 30 minutes to build, and it can fit in your pocket! The purpose of this pouch is to prevent access to your phone and its data (e.g. location) if and when you so choose. Before placing in the pouch, be sure to put your phone in airplane mode as the phone will drain its battery trying to find a signal. Materials -- Conductive fabric Sized to fit your phone + a top flap. Tools -- Scissors-- Ruler-- Needle or Sewing Machine (preferred)-- Safety pins (optional but helpful) Build it! 1. 2. To double check your measurements, mark where you plan to cut the conductive fabric w/ a pen or pencil. then wrap the fabric around your phone. 3. How to Crowdfund Your Next Big Idea.

Cult favorite video game developer Double Fine recently shocked investors by raising over $1 million in 24 hours on Kickstarter for its new adventure game, despite the genre’s supposed death. This has led critics to speculate that crowdsourcing isn’t just the hottest new thing to happen to startups and small business owners since Apple’s App Store; it may also present tomorrow’s most promising new source of venture capital and angel investment. From both research and ROI perspectives, the model makes sense. Why spend years building a better widget when you can instead find and fund tomorrow’s next million-dollar idea simply by asking potential customers? How Do I Create a Business Plan?

How to Make Magnesium Oil to Improve Sleep and Reduce Stress. I’ve written before about how I use magnesium daily and why I feel it is such a vital part of overall wellness .
Many people are deficient in this vital mineral that the body uses for hundreds of reactions. Every cell in the body needs magnesium in some way, and it is vital for bone, tooth, muscle and joint health as well as for optimal sleep and stress reduction. Deficiency of magnesium is widespread because many of us have lifestyle factors that actively deplete magnesium such as lack of sleep, excess stress, or alcohol/caffeine/sugar consumption.

Controlling lights and sensors with Arduino Yún, Node js server and firmata. Controlling lights and sensors with Arduino Yún, Node js server and firmata Zoe Romano — June 3rd, 2014 Arduino user Cinezaster sent us a project using Node js server on the Arduino Yún to control the lights, heating and some other sensors in the office of Appsaloon, the company where he’s doing an internship.
They already use Node.js for a lot of things and some of them are pretty cool with it. That’s how they did it: First of all you need to expand your flash, because there is not enough flash (16 MB) on the Arduino Yún. How-To: Make an RGB combination door lock (Part 1) Skywatching, Telescopes & Astrophotography. Ever since it returned to the evening sky just over a month ago, our "sister planet," as Venus is often called, has been the centerpiece of the current evening sky.
As Venus travels around the sun inside the Earth's orbit, it alternates regularly from evening to morning sky and back, spending about 9 1/2 months as an "evening star," and about the same length of time as a "morning star. " Some ancient astronomers actually thought they were seeing two different celestial bodies. They named the morning star after Phosphorus, the harbinger of light, and the evening star for Hesperus, the son of Atlas.
It was the Greek philosopher and mathematician Pythagoras who first realized that Phosphorus and Hesperus were one and the same object. To the ancients, such behavior was puzzling and was not really understood until the time of Galileo. Easy to Build WIFI 2.4GHz Yagi Antenna. The building steps are simple: 1.
Print out the scaled Yagi antenna template* (download from next step). 2. Trim paper clips to size and glue them to the template. 3. Yagi-pdf/cheapyagi.pdf. Listening to Satellites with a Homemade Yagi Antenna. One of my favorite things to do is talk with other ham radio operators through satellites or the International Space Station (ISS). To do this, I stand on a rooftop and tune a handheld multiband radio while tracing the orbit of a satellite or the ISS with my homemade yagi antenna. Orbiting satellites such as AO-51, SO-50, and AO-27 act as repeaters, relaying signals from low-power transceivers like mine back to hams elsewhere on the planet.
So if you know where to aim the antenna, you can communicate around the world via space. Build one Yagi ANTENNA. After the drill came the time of the saw... Do a slash of 1 cm (0.39 inch) of depth (split) to surroundings of every extremities of tubes of 8mm (0.31 inch). It will permit a better tightening by necklaces, of Circles of 6mm (0.23 inch) that will slip inside himself.
Cut with the saw to metals one of round of 6mm (0.23 inch) to the middle (50 cm 19.68 inch) . Is going to permit you to lengthen one of diameter 8mm (0.31 inch) tubes in order to get the 1,5M (59 inch) of the reflector. For it slip each of pieces of Circle of 6mm 0.23 inch) in extremities of the 8 mm (0.31 inch) tube and adjust an overtaking of 25cm (9.84 inch). 25 cm of part is other deal 50cm (19.68 inch). Arduino Astronomical Clock for Automatic Light Control. Arduino Astronomical Clock for Automatic Light Control There are many ways to automatically control these lights. The gadget I was using (until I completed this project, that is) was a simple mechanical timer. This product allows you to set separate turn-on and turn-off times and those repeat every day. The disadvantage of this product is that, as the seasons change, you need to constantly adjust the turn-on and turn-off times. Gelandagan's Metal Marker MkI - Electro Etcher.
Ok, success! How deep? Well it is adjustable, based on the length of time the current is applied. Can it be personalized? I am working on it. ArduinoBoardEsplora. Overview The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding Arduino boards in that it provides a number of built-in, ready-to-use setof onboard sensors for interaction. It's designed for people who want to get up and running with Arduino without having to learn about the electronics first. For a step-by-step introduction to the Esplora, check out the Getting Started with Esplora guide.
The Esplora has onboard sound and light outputs, and several input sensors, including a joystick, a slider, a temperature sensor, an accelerometer, a microphone, and a light sensor. Like the Leonardo board, the Esplora uses an Atmega32U4 AVR microcontroller with 16 MHz crystal oscillator and a micro USB connection capable of acting as a USB client device, like a mouse or a keyboard. 3V to 24V Variable Power Supply. This 3V to 24 volt variable-regulated power supply can be adjusted from 3 to 25 volts and is current limited to 2 amps as shown, but may be increased to 3 amps or more by selecting a smaller current sense resistor (0.3 ohm).
