Guy Creates A Lamborghini Reventon From Scrap Interesting news here today. Wang Jian, a 28 year old Chinese farmer made his own Lamborghini Reventon from mere scrap metal. The rare Italian luxurious Reventon is with very few peoples in the world due to its high cost. Like many car lovers, Lamborghini Reventon was Wang Jian’s dream too. Blokker 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.

LEGO Mindstorm Activities LEGO Mindstorms is an excellent toy line that allows children and young adults to explore basic robotics with the ease of construction of the classic LEGO toy. The LEGO Mindstorms set comes with everything you would need to get started with input and output functions in robotics, including a microcontroller, touch sensors, an ultrasonic sensor, light sensor, servos and gears. With these elements and others available for purchase, you can easily create countless robots and machines. Barcode Scanner Using the light sensor and a little coding, you can create a barcode scanner that will read either real barcodes or ones you construct from LEGOs. The microcontroller is given a set of data that links a given barcode to a string of information, and as the barcode is placed over the light sensor, the string of information is registered and displayed.

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.

Mercedes V-12 Engine Made From Hand-Made Components Artist Eric van Hove has been very busy with his recent project. He has taken apart a V12 Mercedes engine and had the parts reproduced using a wide variety of unexpected materials. He had the help of local Moroccan artists who made the parts for him using their unique skills and different replacement materials. These components are made from some of the unlikeliest substances you could imagine. The V12 Laraki, as it is called, took nine months for van Hove to complete.

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 %. Onager (siege weapon) This article is about the siege weapon. For the equine species, see Onager. Sketch of an Onager, from Antique technology by Diels. The onager's framework is made out of two beams from oak, which curve into humps.

100 Websites To See Before You Die (Part 1) Here at Maximum PC, we've always done our fair share of website recommendation articles--including a couple of doozies from the past few years. And of course we're not the only ones who do this sort of article either; it's a proven popular format. But this year, we thought we'd mix things up a little bit. Rather than just focusing on what's services are popular, or which web apps will make you the most productive, we wanted to take a look at what's fun on the Internet. In that spirit, our February cover feature is going to be 100 Websites You Need to Visit Before You Die.

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. All about Catapults What is the real history of these war machines? Actually, we don't have a lot to go on. At the end of the 19th century, the nobleman and amateur historian Ralph Payne Gallwey wrote a book about the crossbow, and in it he describes the "catapult", what modern historians call a mangonel or onager. Unfortuantely, we now know that most of his sources are fiction. He even invented fake reference numbers for them at the Bibliothec National in Paris, France.

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 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)
