How to Spot Planet Venus in the Sky | Phases of the Planet Venus | 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.

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.
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). The 2N3055 and 2N3053 transistors should be mounted on suitable heat sinks and the current sense resistor should be rated at 3 watts or more. Voltage regulation is controlled by 1/2 of a 1558 or 1458 op-amp. The 1458 may be substituted in the circuit below, but it is recommended the supply voltage to pin 8 be limited to 30 VDC, which can be accomplished by adding a 6.2 volt zener or 5.1 K resistor in series with pin 8. The maximum DC supply voltage for the 1458 and 1558 is 36 and 44 respectively.

Your CPR certification for adults does not automatically mean you also know the correct way to perform CPR on a puppy. Chest compression for humans and dogs involve forceful motions, with one hand on top of the other on the surface of the chest. However, this sort of force may do more harm than good when dealing with a puppy. Learn the steps to modified respiration and CPR for puppies to increase their chance of survival.

Last week, we talked about how to transport dry ice on your trip, but what about using dry ice once you get where you’re going? Dry ice can help keep food cold or frozen during your camping trip when used properly. Here are a few tips to help ensure your dry ice will keep your goods colder longer. Pack frozen foods and chilled foods in separate containers. There are specific packing techniques for each type of good, which you can find in our basic packing post or our everyday uses guide . Make sure to pack enough dry ice to last throughout your trip. Using Dry Ice on Your Camping Trip « Dry Ice Ideas | Penguin Brand® Dry Ice

Common Mistakes of Electronics Repair Many of us have been interested in electronics repair from a very young age, but to some, the interest could have started in our 40’s or even 50’s! No matter what your age, electronics repair is fun and this hobby can be turned into profits if you know what to do with your knowledge. It is very exciting when you discover that electronics repair is the field that is really meant for you. Day and night you search the web for more information about electronics repair and hope to be able to understand and solve electronics problems. common mistakes in electronics repair
AKA: Snijlab-style living hinges, Sninges, Laser cut hinges, or my prefered title: Lattice Hinges Flexi-Acrylic Test by Solarbotics, on Flickr After this style of hinge popped up again, this time on Makezine , I was having a look at the linked project guide and at how they worked and I realised that a bit of mathematical modelling could lead to better designed hinges. This could mean fewer rounds of trial-and-error prototype tests, which would reduce the cost of using lattice hinges in a project, and better fatigue resistance, meaning the hinges could be used for moving parts instead of just for static bends. Download links for the test specimen files are included at the end of this post. This style of hinge appeared recently in the work of Snijlab , a Dutch laser cutting workshop when they showcased a folding notebook cover mode from a flat sheet of laser cut plywood.

Editor’s note: Rick Kelly (@_rickkelly) is an adjunct political science professor at BYU-Idaho and MBA student at UNC-Chapel Hill. Remember SOPA? In case you’ve forgotten already, earlier this year some Congressional legislators attempted to protect intellectual property through the Stop Online Piracy Act (SOPA). The language in the bill was far-reaching and ambiguous; thus prompting concern that application of the law would extend beyond its intent. TechCrunch’s own John Biggs explained that SOPA “would allow the US government to essentially ‘turn off’ part of the Internet that it doesn’t like.” The Next Battle for Internet Freedom Could Be Over 3D Printing
Recycle, reuse – thats the motto we have all been trying to live by ever since this “global warming” issue came into effect but now it just got a bit easier.

first image flexible sheets of wood dutch digital manufacturing company snijlab has developed new possibilities of working with wood. using laser cutting technique they make tiny cuts in wooden sheets that allow it to be flexible. once processed the wood can be fully bent in both directions without breaking. snijlab makes wooden booklets with the bendable wood technique. the cover is a single sheet of wood cut from a beautiful birch plywood and finished with a clear varnish. cuts in the middle allow the cover to be flexed open and really; it's only wood! folding wood
