Gold Recovery Wait don’t throw those old electronics in the garbage, there’s gold in them there things. How about putting it in your pockets instead of someone else’s pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards even printers and scanners have gold, silver, and copper, even platinum in them. Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Things You Will Need: Scrap electronics Rubber gloves Rubber apron Goggles Hydrogen Peroxide 3% I got from local pharmacy. Although no special skills are needed one should follow all chemical and heat safety procedures.
Wind Turbine Output Boosted 30% by Breakthrough Design Clean Power Published on April 29th, 2009 | by Timothy B. Hurst Passive structure design of “Wind Energizer” by Leviathan Energy reportedly increases wind turbine efficiency 30% in field tests. Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about it. The principle theory at work is that by placing passive objects around a wind farm it will change the circulation around a large wind turbine. “This is a disruptive technology,” Leviathan Energy CEO Dr. Farb is a bit of a modern day renaissance man. The Wind Energizer is a donut-shaped structure made from steel and plastic, but the exact dimensions of it depend on site-specific data, like the tower height, length of the blades, prevailing wind direction and intensity, etc. Images courtesy of Leviathan Energy Timothy B.
DIY 360 Degree SODAR Device First off, why did we decide to call this thing SODAR? SOnic Detection and Ranging, or SODAR, is a lot like SONAR and RADAR. However, we don't feel comfortable calling it SONAR because we have no desire to use it for navigation and we aren't under water. Also, it's definitely not RADAR as we are using ultrasonic pulses, not radio waves to find objects. With the technicalities out of the way, here are the project's objectives: 1) To create a freely rotatable SODAR system that can continuously detect objects 2) To create a UI that displays objects similarly to radar 3) To make it as portable as possible To accomplish objective #1, we need a way to prevent wires from tangling while the motor spins. While it seems to go against objective #3, we decided to go with the rotating electrical connection idea. Future Work Suggestion: Use wireless transceivers so the project can be placed in one area and send data to the laptop in another area. Collaborator:
How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. . Finally!
Business Events Finder Online investing, equity crowdfunding, business finance : Crowdcube Hour of Code | Editor Hints after video one. This may never be seen? Draw a picture made of ellipses and rectangles! For example, you could make a self-portrait, an alien creature, or something more abstract. You can work on your own pace, but we recommend approximately ten minutes on this assignment before moving on. Reminders To draw a rectangle: rect(a,b,c,d); To draw an ellipse: ellipse(a,b,c,d); a — X (horizontal) location of the shape's upper-left cornerb — Y (vertical) location of the shape's uppper-left cornerc — width of the shaped — height of the shape For more, check out the rectangle and ellipse pages on processing.org. Add color to your design! You can build off the example below or add to your previous design by selecting "My Code from Last Lesson" under the "Code" menu below. Reminders Set the background color: background(r,g,b); Set the outline color: stroke(r,g,b); Set the interior color: fill(r,g,b); Don't forget, you need to call stroke() and fill() before you draw the shape! rect(250,200,100,75);
Construct 2 - the HTML5 game I’ve been experimenting with Construct 2 from Scirra the last few days. Construct 2 is a program from creating HTML 5 games. What really got my interest was that there is the ability to create Windows 8 games using Construct 2 with Visual Studio 12. The Construct 2 development environment is pretty easy to use and I find that some similarities to Visual Studio (among other tools) is helpful in finding ones way around it. The image below shows the layout of graphical objects on the screen as well as the properties box, list of images and outline of the project. Very similar to what I am used to. The coding involves what is called an event sheet. I really like that for a single event you can easily specify different actions for different objects in the game. Programs/games are created in the Construct 2 IDE and tested in a web browser. Getting started links:
