Bow building for poor people and apartment dwellers Brought to you by: SAM HARPER by Sam Harper Why am I doing this?
A couple of years ago (or was it last year?) And I says to myself, I says, "Hey, I think I could make that. " After posting that picture on the "What to do with scrap wood" article, somebody emailed me requesting a build along. Thinking it through So far, I haven't done any measuring to make these. Basically, you're going to be cutting all the pieces into trapezoid shapes and gluing them together in the round. Now, looky here at these two tankards. Notice how they both have eight pieces of wood to complete the circle, and notice that the angle of the cuts is the same with each. Although we are going to start off with a polygon, we want to end up with a round tankard. Notice that although they have the same diameter, the one on the right uses twice as many pieces as the one on the left. So here's how to figure out the angles to cut your pieces. 360º/8 = 45º (180º - 45º)/2 = 67.5º.
How to Make Chainmail - Animated - By West Coast Chainmail. Carbon Fiber Primer. It seems as though nearly everything “high performance” these days boasts some amount of carbon fiber in its construction. Originally used in aerospace, carbon fiber has moved into the mainstream and can be found in luxury automobiles, mountain bikes, and sports equipment. Some laptops and cellphones even use printed decals to simulate this lightweight material’s cutting-edge look.
The good news is that you don’t need a state-of-the-art manufacturing facility to work with carbon fiber composites. In fact, you can do it at home. This article discusses some of the basics of carbon fiber construction and explains how to create a carbon fiber iPod case. All you need are some basic woodworking tools and skills, and the right materials. It should be noted that the techniques demonstrated in this project are simplified so that the average hobbyist can perform them at home. Understanding Carbon Fiber Composites are created from two or more dissimilar materials that act together as one. Intro to 3D Modeling: The Complete Guide. DIY machine shop: Four essential tools you can build from recycled parts. The Multimachine is one of Pat Delany's most well-known tool designs for machine shops in impoverished communities. Photo courtesy of Pat Delany There may only be a handful of people in the world who have thought as deeply as Pat Delany has about making cheap tools.
Delany, from Palestine, Texas, designs hand-powered tools made of recycled materials. His heavy-duty drills, lathes, saws and other tools can handle the same tasks as modern power tools, but they equip carpentry and machine shops in off-grid and impoverished communities. To achieve their low-tech precision, his designs fuse century-old technology, present-day scrapped auto parts, pipe, concrete, wood and a relentless commitment to the bottom line. Four essential toolsAt Maker Faire Africa 2010, Delany gave a presentation on how to build four essential tools. They are his Multimachine, a screw-cutting lathe, a treadle-powered electricity generator and a steel drill. The Top Nine Consumer 3-D Printers For Every Budget. These 3-D printer things sound pretty cool, right? Prototypes printed right on your desktop! All you need is a CAD file (your own or one of thousands from an online database like the Etsy-esque Shapeways ) to turn digital dreams to plastic reality. But as 3-D printing becomes more popular, the number of consumer devices available for purchase is exploding.
Which one should you buy? Here’s a breakdown, by cost, of the best consumer 3-D printers on the market today. The Ultra Affordable If you’re looking to spend under $1,000, don’t expect perfect, prototype-ready builds without working for it. Printrbot Simple, $299 The cheapest mass-market model available today is the $299 Printrbot Simple . Kinpo da Vinci, $499 Taiwanese Kinpo Group just announced their XYZprinting line, which includes the vaunted $499 “da Vinci” model. RepRap Open-Source Line, $439-$621 (does not include printed parts) Imagine a cheap, efficient 3-D printer that can print out more 3-D printers. Mid-Range Workhorses. 3d printer - search Instructables. USB Typewriter. There is something very magical about typing on those old-school manual typewriters. From the satisfying snap of the spring-loaded keys, to the gleam of the polished chrome accents, to the crisp marks on the printed page, typewriters make for a sublime writing experience.
Now, the USB Typewriter lets you enjoy the magic of writing on a manual typewriter, without forfeiting the ability to use word-processing, email, web-browsing, or other modern desktop conveniences. Or, instead of using the typewriter as a computer keyboard, you can turn off your monitor altogether and type directly onto paper -- while discretely saving a soft-copy for later use! In this instructable, I'll help you bring your old typewriter back to life by converting it into a USB compatible keyboard for your PC, Mac, or tablet computer. Read on, and you will see that this modification is surprisingly easy to implement -- It shouldn't take longer than a weekend to do, and is within reach of any electronics novice.

DIY Super-Noise-Canceling Headphones. I just moved in to a new apartment for the beginning of this school year. I like my apartment a lot; it is very modern, it is big, I think it is fairly defensible in case of a zombie apocalypse, but there is one problem: there is always a lot of noise. Between the TV being on all the time with high volume, and people constantly chatting, and sounds from the kitchen, and noisy neighbors, it can be difficult to get some peace and quiet. So, in the interest of being able to listen to music, relax, and, of course, do homework, I started shopping for noise-canceling headphones. Unfortunately, noise-canceling headphones can be quite expensive, especially high quality ones. This Instructable will show you how to make headphones that block just as much noise as those high-end brands I just mentioned but cost less than $35.
