Related: manufacturingBlokker I/C ignition A good spark is crucial for an IC engine like the Puppy to run reliably and that is often a headache for mechanical orientated model builders for various reasons. Lack of knowledge and experience is one cause but also dimensions, availability, the price, the complexity of the systems or components can all be obstacles. I myself belong also to this category of model builders and I have been wrestling with this problem for as long as I have made IC model engines.
- StumbleUpon Reynolds Wrap has lock in taps to hold the roll in place The color on the bread tab indicates how fresh the bread is And those colors are in alphabetical order: b, g, r, w, y. You can divide and store ground meat in a zip loc bag. Just break off how much you need and keep the rest in the freezer for later.

How to Build Creative Confidence in Kids — IDEO Stories How to Build Creative Confidence in Kids By Sally Madsen with Holly Kretschmar Kids are creative, every moment of the day… in the way they draw, the way they experiment with language, the way they interact with objects, the way they imagine new worlds. At IDEO we believe that creative confidence — believing in your ability to create change and having the courage to act on it — is something all of us are born with. But as David and Tom Kelley write in the book Creative Confidence, too often people lose this innate ability as they grow. Gears- Gear Efficiency Introduction Important Note: The equations used are mainly derived from the technical information provided in the SDP/SI technical library see links below. I recommend that for serious work the linked information is more suitable. The efficiency of a gear system is simple calculated as the [output shaft power /Input shaft power ].100 %.
Inception in Real Life: Make These Lucid Dreaming Glasses and Take Control of Your Dreams Inception in Real Life: Make These Lucid Dreaming Glasses and Take Control of Your Dreams Dreams are like an internal human holodeck. Inside your mind, anything is possible, from your grandest wishes to your worst nightmares. This is all well and good, but what if you could control your dreams and become the omniscient god of a handpicked reality whenever you go to sleep? Inception took this idea to the logical extreme by invading other people's dreams. The Tesla Gun The year was 1889. The War of the Currents was well underway. At stake: the future of electrical power distribution on planet Earth. With the financial backing of George Westinghouse, Tesla’s AC polyphase system competed for market dominance with Edison’s established (but less efficient) DC system, in one of the ugliest and most epic tales of technological competition of the modern age. More than a hundred years after the dust settled, Matt Fraction and Steven Sanders published The Five Fists of Science: a rollicking graphical retelling of what really happened at the turn of the last century.

Modern History of Wire Rope Modern History of Wire Rope by Donald Sayenga It wasn't until recent history (the 1600-1700s) that most of the technical breakthroughs in the modern history of wire rope were achieved in Europe. This was followed by a remarkable 40-year period, between 1849-89, when a majority of the basic forms of wire rope still in use today all over the world were devised in the United States.

The Factory Floor, Part 1 of 4:The Quotation (or, How to Make a BOM) This month, I will be teaching a few MIT Media Lab graduate students and doing a bit of a “geek tour” of Shenzhen – we will visit several factories and live among the electronic markets to facilitate new directions and expand horizons in the students’ hardware-oriented research projects. As part of the course, they will learn how to scale up their research utilizing the China manufacturing ecosystem. These lessons may also be useful for Makers looking to bootstrap a product in moderate volumes (hundreds to thousands of units). I will share some tips and insights from the course in four posts over the next month covering: Getting a quotation: documentation standards (how to make a BOM) Process optimization: design for manufacturing and test jigs Industrial design for startups: guerrilla engineering on a shoestring budget How to pick a factory: building and maintaining partnerships Part 1 of 4: The Quotation (or, How to Make a BOM)
Carved Book Landscapes by Guy Laramee (click images for detail) For the better part of three decades multidisciplinary artist Guy Laramee has worked as a stage writer, director, composer, a fabricator of musical instruments, a singer, sculptor, painter and writer. Among his sculptural works are two incredible series of carved book landscapes and structures entitled Biblios and The Great Wall, where the dense pages of old books are excavated to reveal serene mountains, plateaus, and ancient structures. Of these works he says: Cleaning Parts Cost Effectively Article From: 3/18/2013 Production Machining, Chris Felix , Senior Editor Click Image to Enlarge After machining, most parts are coated with some residue consisting of either aqueous or oil-based cutting fluids and swarf. This comparison shows parts before cleaning (top) and after cleaning in an iFP Kleen Power vacuum parts washer. The iFP Kleen Power vacuum parts washer offers an optional automation system for moving parts in and out of the chamber. Once the chamber door is sealed, a pump pulls the air out of the chamber to create a vacuum and the chamber is filled with the appropriate solvent.
