The microhydro plant

The microhydro plant
My little paradise has a stream that provides enough water flow and head to run a small turbine, to provide electricity to my home. While writing this, the microhydro plant is being implemented, and here are some photos of the process. Since I usually like to start at the end, the first thing I built is the controller: It is an implementation of Jan Portegijs' "Humming Bird", with some changes and adaptations. The largest cost of the plant, by far, is in the piping for the rather long penstock. When the purchase was made and the truck arrived, we unloaded the pipes at different places, to get them as close to the installation area as possible. A smaller number of pipes were stored closer to the turbine site. Only for the last part of the run, where the pressure exceeds 2 bar, I will use blue class 4 PVC pipe. To change from the low slope run of the white pipe to the much steeper run of the blue one, a change of direction is required. The flat area is where the forebay will be built. News!

Chocolate Chip Cookie Dough Peanut Butter Cups Soooooo… you know that episode of Sex and the City where Miranda has to dump dish soap on top of chocolate cake just so she will stop eating it?? Uh. Yeeeeeah. These are like… of that caliber. And that totally almost happened to me. I ate what felt like a million, then had a plate of 5-day old green bean fries from the fridge and called it lunch. I definitely recommend those. For lunch. Face? Inhale. Chocolate Chip Cookie Dough Peanut Butter Cups [cookie dough adapted from cookie dough dip] makes 24 cups 2 1/2 cups milk chocolate chips 1/2 cup unsalted butter 1/3 cup packed brown sugar 1 teaspoon vanilla extract 1/4 cup creamy peanut butter 3/4 cup powdered sugar 2 tablespoons all-purpose flour 1/4 teaspoon salt 1/2 cup mini chocolate chips In a small saucepan, heat butter until melted. Line a mini muffin with with liners. Remove muffin tin and cookie dough, then place 1 teaspoon of cookie dough (I somewhat rolled mine) into the chocolate cups. Sigh.

Emergency Party Button The Emergency Party Button began as a novelty idea that has become the focus of every event that goes on in our home. A big red button is, by human nature, an object of compulsion. If you see it, you are overcome with the desire to push it. But what happens when you do? Details The Emergency Party Button consists of 3 major components: The actual button itself, the controlling computer, and all the controlled devices. At the heart of the button is a Basic Stamp II (well, technically, a Basic Stamp Homework Board, since it wasn't going to any good use anyways). Once the X10 transceiver receives the wireless signal from the party button, it then forwards it out towards a computer that is always listening for the signal. Once the party has started, at any time the party button may be pressed again. Devices Blacklights There are 2 blacklights: On on top of the entertainment center and one on top of the curtains.

This 1,400-Foot Desert Citadel Would Be A Self-Sustaining City Of Tomorrow It may look like Immortan Joe's Citadel from Mad Max: Fury Road, but this abstract desert obelisk isn't a citadel of the post-apocalypse. It's a self-contained city—also called an arcology—that French firms Nicholas Laisné Associés and OXO Architects propose to build in the Saharan desert. Although it's just a concept right now, La Ville Tour Des Sables (translated: "The Sand Tower Town") would stand over 1,400 feet, if completed. Designed to resemble an outcropping of stone—or, at least, Bjarke Ingels' idea of what an outcropping of stone might look like—the arcology would contain everything needed for a self-sustaining city, including living quarters, agricultural units, factories, and more. According to OXO's official description of the project, the Sand Tower Town would have a total floor space of around 192 acres. Another big aspect of the design involves making maximum use of the desert's resources. [via io9] [Images: via OXO Architects]

Eun-Gyeong Gwon & Eun-Jae Lee This one’s kinda hard to swallow so take a deep breath, open your minds, and pretend it’s 2100. I CONTACT is essentially a mouse fitted to your eyeball. The lens is inserted like any other normal contact lens except it’s laced with sensors to track eye movement, relaying that position to a receiver connected to your computer. Theoretically that should give you full control over a mouse cursor. The idea was originally created for people with disabilities but anyone could use it.

How to Travel Full-Time for $17,000 a Year (or Less!) Wise Bread Picks For the last five years, I've been traveling the world full-time, and for less money than I've ever spent (and I'd wager less money than most people would spend) to live in one place. My worldly possessions fit into one bag (just larger than carry-on size) and a backpack containing my laptop and computer gear. In 2011 alone, I traversed 13 countries and over 45,360 miles. What if I told you it wasn't? Believe it. How to Keep Your Travel Costs Low Of course, I could travel for way more than $17,000/year. Here are a few of my secrets. Don't Pay for Accommodations In the entire year of 2011, I paid $173 for accommodation. Work-Trade/Volunteer There are lots of creative opportunities to work in trade for your accommodation (and sometimes food) and enjoy a more immersive travel experience.

Electromagnetic Coilgun Doesn't Need a License Robert Wilsford created an Electromagnetic Coilgun from some very common items that can be found easily on the websites, so you can also try this and make a nice gadget sitting at your home sweet home. I like guns a lot, but we can’t keep them at our homes without a license but this gun doesn’t need any license such as the Steampunk Coilgun. Well! If you are arsenal lover like me, needless to say, you would dare to make this gun. Now promise me that you won’t create much fuss as your parents might get angry over me to have shared its creation basics. The outer body of the coilgun is made from wood, plexiglass and metal while in the interior electromagnetic coils have been used coils to push a ferromagnetic projectile (here round ball like bullet of steel) at a great velocity through a barrel. In tools you would need a Solderer, Pliers, Wire Cutters, Wire Stripper, Scissors, Glue Gun and a Flat Head Screw Driver. Via: Hacknmod

Virginia SUN | Citizens for Solar One can dream Once upon a time there were some very well-off folks in Vancouver who wanted big new homes. They called upon a builder by the name of Keystone Projects Ltd. and asked them to build the homes of their dreams. They asked for fancy kitchens and bathrooms and rooms for their pool tables and views to die for and a car lover's garage.
