Let there be (Random) light. « Door Sixteen. Hey, remember when Daniel performed a thrifting miracle and produced a Random Light seemingly out of thin air for about 85% off retail? That was almost NINE MONTHS ago, during which time said lamp has taken up a bunch of space doing absolutely nothing on the floor of the room at the back of the house (also known as Evan’s studio). Well, no more!! It is FINALLY suspended from the ceiling and emitting light. Yay! We hung the lamp kind of low directly above the desk. Better photos to come once the room is fixed up a bit more!

Eco DIYs: Vertical Axis wind turbine made from PVC pipes. Video de en youtube - How the Dyson Bladeless Fan Works" In October 2009, James Dyson's consumer electronics company, famous for its line of vacuum cleaners, introduced a new device to the market called the Dyson Air Multiplier. The Air Multiplier is a fan with an unusual characteristic: It doesn't have any visible blades. It appears to be a circular tube mounted on a pedestal. The shallow tube is only a few inches deep. Looking at the device, you wouldn't expect to feel a breeze coming from the mounted circle.
There are no moving parts in sight. But if the fan is switched on, you'll feel air blowing through the tube. How does it work? As you might imagine, there are a few scientific principles at play here. According to Dyson, the breeze generated by the Air Multiplier is more consistent and steady than one from a standard fan with blades. What's the secret behind the technology? Table belt sander (lijadora de banda, de mesa) Hace unos meses me regalé una lijadora de banda. Es una excelente herramienta, versátil, resistente, poderosa. Pero... siempre tiene que existir un "pero".
Para trabajos pequeños es algo difícil de manejar. Por ejemplo, para lijar piezas chicas, suelo ponerla "patas para arriba" sobre las piernas y sujetarla entre las rodillas. Así arruiné un pantalón, ¡y que no se entere mi mujer! Ayer estaba a punto de volver a hacer lo mismo, pero se me ocurrió buscar la manera de poder fijarla sobre la mesa de trabajo para no correr más riesgos. En unos minutos me convencí de que era factible, máxime teniendo a mi disposición varias maderas viejas. Publico este instructable porque estoy seguro de que le será útil a más de uno. A few months ago I bought myself a belt sander. Yesterday I was about to do the same, but I decided to find a way to fix it on the bench, not to take more risks.
Convex Glass Tile from Bottles. Mini-Tablesaw / Router / Shaper for Dremel rotary tool. Lawnmower Power Generator With A Twist. This is a 500 watt power generator big enough to power tools, and home electronics. If you try plugging in kitchen appliances, heaters, window AC units etc....it will shut down, you need a 2k-3k watt power converter for large power comsumption appliances.. It's not difficult to build this project, if you know how to wrench things apart and have a basic understanding of how things work with engines and electrical components then you'll do just fine. If you want to save money on the build, go to junkyards, recycling centers, and landfills which is where I got most of the parts. You'll be surprised the stuff you can find for pennies or better yet FREE. I spent $40 for all the parts needed for this project. There are a few optional parts not needed to run this little power jewel. How to Pack: Shipping Big Science. Anyone who has ever packed anything, from a homemade ceramic mug that you only need to get across the state, all the way up to this telescope that needs to cross many continents, knows that shipping can be a dodgy proposition.
The secrets are to have 1) a structurally sound box -- one that isn't going to crush or crumple, and that is well-supported and braced on the inside and 2) make sure the item you are packing is surrounded -- tightly packed -- with material, or generally otherwise constrained -- so that if the box is impacted, the object experiences little of the force. Packed, literally. The ART crew did all of this with very high quality materials (e.g. no two-by-fours -- all milled lumber), the right types of materials (angle brackets when necessary, stiff foam when necessary), a clear minimum of excess packing material, very exact measurement and fitting tolerances, and a generally all-around incredibly high level of expertise. 12 Storage Tote Shelving System $50.00. Hello all! Today I wanted to share with you how I made my storage bin shelving system for my garage. It holds 12 totes! Here is a short story why I made this instead of purchasing one. I have over 40 totes in my garage.
I needed a sturdy shelving system to organize them so I could still get to one on the bottom without moving all the other totes off of it. I went online and priced them at all the hardware stores and garage centers I could manage to find and almost got sick because the cheapest I could find worth a darn was over $130.00!! No way could I afford 4 of them! I decided to make one for a lot less then the going price so I went to my home improvement store and did the measurements! Tiffin Box from Tuna Cans. The can rolling jig consists of two old door hinge pins and a hose clamp. The heads of the hinge pins nest with each other. By applying pressure with the clamp and rolling the can, we can raise a lip on the can's side. Check out the embedded video in the next step to see it in action. Building the jig is very easy. The top pin will stick out further than the bottom on account of the heads being nested. Use a vise to clamp the wood and hold the whole thing steady.
Step-by-Step Earthbag Building. This Instructable explains each main step of construction for building vertical earthbag walls. Videos on my Earthbag Natural Building YouTube channel demonstrate the process. For those who don’t know, earthbag building uses polypropylene rice bags or feed bags filled with soil or insulation that are stacked like masonry and tamped flat. Barbed wire between courses keeps bags from slipping and adds tensile strength. The final plastered walls look just like adobe structures. Thousands of people are now building with bags to create their dream homes, home offices, shops, resorts, rootcellars, storm cellars and survival shelters. Non-profit organizations are building schools, orphanages, emergency shelters and other structures. I got involved with earthbag building when the Indian Ocean tsunami hit Southeast Asia in December, 2004.

We built this earthbag roundhouse in 2010 as part of an earthbag workshop in Thailand, and finished it later that summer. Roundhouses are perhaps the simplest, fastest, easiest earthbag structure to build. The other key advantage of earthbag is cost.
Basic project information: 18’ exterior diameter; 15’ interior diameter; 177 sq. ft. interior floor space; total cost of materials: $2,045, which is about $11.50/square foot.

We built this earthbag dome at our home in Thailand for Mother Earth News Magazine in 2007. The article that describes the complete building process in detail was published August/September 2009. It is now free on the Internet: Low-Cost Multipurpose Minibuilding Made With Earthbags , by Owen Geiger. This earthbag dome Instructable simplifies the process and illustrates each step of construction with photos. This multi-purpose dome can serve as a storage shed or cool pantry above ground, or as a rootcellar or storm shelter below ground. The key concept that makes earthbag domes work is corbelling. Cigar Box Ukulele. Materials: Cigar Box. If you have a choice, find one of solid wood. I found a cedar box with a plywood base. I paid 4$ for mine, but it shouldn't really cost more than 2$.
Wood for the neck and bridge - for a concert sized ukulele I needed a 14 x 2 x 2.5 inch block for the neck and head. The bridge will be about 2.5 x .5 x .75 inches. Wood for the lid supports: the cigar box will vibrate with the strings. Wood for the inside supports: These will go around the edges of the box for added strength and for a place to anchor the neck. Wood for the fretboard: I chose red oak. Material for the saddle and nut: I used dominos, which I cut down to size. Material for the frets: I actually bought brass welding wire for the frets, but ended up inlaying crushed turquoise instead. Fret markers: Ukes are usually marked at the 5th, 7th, and 10th frets. Ukulele strings: see your local music store. Tuners (set of 4): I took the tuners from a busted kid's electric guitar I got at a thrift shop. Wood Glue. DIY High Speed Book Scanner.
Joe Grand’s LED Watch Flashes Time in Midair. We’ve covered a few of Joe Grand’s projects on the site before and here’s another fantastic project to add to the collection. This POV (persistence of vision) watch displays the current or elapsed time while the arm is swinging (such as during a run or brisk walk). A sequence of LED patterns from the watch are displayed in quick succession appearing in “thin air.” Build it Yourself You’ll find schematics, gerber files (learn how to design schematics in eagle), source code and everything you need to create your own POV watch. More POV fun We’ve covered plenty of POV projects in the past, a few of which even made it onto our top 40 arduino projects list. The image above is this POV bike project and there’s also this wireless version.

Instead of paying for absurdly priced printer cartridges, build yourself a Continuous Ink Printer (CIS) which can be made by hacking an old printer to suck ink from external reservoirs. You can get the raw ink for dirt cheap so it’s essentially like unlimited printing for free (besides the paper). So now you can actually print your collection of pirated books! A CIS is relatively easy to create, just take an Epson Stylus 760 (a surprisingly hard to find printer) and make a few modifications to it. A tutorial walks you through the build process so you can make your own. More Printer Hacks: Next Gen Wind Energy you have Never Seen. Screw Gas – Build an Electric Car.
