Overview and history[edit] The Hungarian-British physicist Dennis Gabor (in Hungarian: Gábor Dénes),[1][2] was awarded the Nobel Prize in Physics in 1971 "for his invention and development of the holographic method".[3] His work, done in the late 1940s, built on pioneering work in the field of X-ray microscopy by other scientists including Mieczysław Wolfke in 1920 and WL Bragg in 1939.[4] The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston (BTH) Company in Rugby, England, and the company filed a patent in December 1947 (patent GB685286). Several types of holograms can be made. Holograms can also be used to store, retrieve, and process information optically.[18] How holography works[edit] Recording a hologram
Stone Island Heat Reactive Jacket *notcot in wearable , 07:18 Thermochromatic goods seem to come and go and never quite disappear… remember when American Apparel brought it back and AZFN did their version too? Well latest to run into is Stone Island’s Heat Reactive Jacket “A hooded bomber jacket in cotton nylon canvas with thermosensitive liquid crystals, the garment changes colour according to the temperature. The fabric of the heat reactive jacket is treated with a thermo-sensitive coating that changes colour at high temperatures. Beginning at 27 degrees the molecules within the micro- capsules of the external strata undergo a rotation modifying the light course.

Disposable Cameras There are lots of disposable camera Instructables on the site. It was hard to choose, but I've included some great ones! Need a taser, a coil gun, a flash grenade? Well then, this disposable camera guide is for you! From simple everyday parts you can make this glove which has two modes. Mode 1 is a constant output of slightly over 300 v. while Mode 2 takes a few seconds to charge, but gives off a much more painfu... Learn how to make a simple but extremely effective Coil gun using only a "few" parts that are fairly easy to obtain by only going to a few places and possibly online. I've come up with a project that i've been contemplating for a long time. Are you tired of having your Ni-Cad batteries that refused to charge and simply die? Well... Caution I'm not liable if your shock yourself and injury or kill your self, working with high voltages can be dangerous!! Before I get too far in this instructable, I would like to say that this was not my original idea.
Whitaker Blackall - Music and Sound FX for Video Games & Music Theory for Beginners: Part I - StumbleUpon Find part two of this article here WARNING: This is a long post. But if you can get through it, you will know a lot of important basics about music theory and production. As some of you know, I’ve been having a blast with my foray into gamedev. I had never programmed a day in my life before October, and now I’m up to making an iPhone Pong clone so I’m pretty excited about that! More to come in future blog posts. While obviously I’d prefer every game developer out there to come to me for music, I think some people want to make their own game soundtracks, and would if they only knew how. Scales, and why you need to understand themChords, and how to form themChord progressions, and how to make themMelodies, and how to write themExtra effects and plugins that fill out your sound I’m going to be using GarageBand in this post, so feel free to follow along. Scales, and why you need to understand them Most beginners really hate scales because they’re boring and don’t seem to do anything.

INTEGRAF--How to Make Holograms "Everything should be made as simple as possible, but not simpler” - Albert Einstein We attempt to follow this dictum so you can make holograms easily. The procedures we propose herein are as simple as it is physically possible. In the process, we make holography not only as simple as possible, but safer, less expensive, and more accessible to young people. Most of the essential items described in this article can be found in Integraf's holography kits or are available separately. The figure below shows a Class IIIa diode laser with an output of 3 to 4 mW when operated by 3.0 v dc. An excellent support for such a small laser is a wooden clothespin, as shown below. The wooden clothespin offers another advantage. The “white light reflection hologram” is the simplest to make. 4.1 Supplies You will need the diode laser discussed above, a supply of Slavich PFG-03M 2.5 x 2.5 inch plates (63mm x 63mm), and a JD-4 processing kit (or PFG-01 plates with JD-2). 4.2 Preparing the object 4.3.

We call it Dot. It’s a stylish, durable and downright pocketable 360º (panoramic) lens attachment and app for the iPhone 4. What does it do? Dot lets your iPhone capture immersive, fully navigable, panoramic video in real-time - and share with friends on your phone, as well as on Facebook and Twitter, or streamed online using our awesome panoramic video web platform and player. Cool, right? We're excited too. But seriously, our secret beta testers have already had a lot of fun taking it to concerts, the park, on moped rides in Italy, and showing cramped apartments to mothers halfway around the world. So? We haven’t slept much. We’ve spent the past few months researching, designing, prototyping and coding. Let's do it! We’re excited to bring our cutting-edge (read: magical) panoramic technology to a much wider audience – and even more excited to see what you guys will do with it. Thanks for your support.

How to create a bootable USB flash drive to install Windows 8 Developer Preview - Habib Heydarian's Blog @ Microsoft Like many folks, after watching the BUILD keynote this morning, I couldn't wait to get home and install Windows 8 Developer Preview on my laptop. The instructions for installing Windows 8 are simple enough. The only fly in the ointment is that installing Windows 8 requires a DVD to create an install package. Of course, since I haven't used an optical drive in years, I didn't have a blank DVD and I didn't want to wait until the morning to buy some. To create a bootable USB flash drive the easy way, you can download the Windows 7 USB/DVD download tool from the Microsoft Store. At a high level, the steps are: Mount the Windows 8 Developer Preview ISO image on your computer Format a USB flash drive Copy the Windows 8 files onto the USB flash drive Make the USB flash drive bootable Install Windows 8 from the bootable flash drive Step 1: Mount the Windows 8 Developer Preview ISO image on your computer The first step is to mount the ISO image on your computer. Step 2: Format a USB flash drive
Arduino GPS Shield Kit - Cana Kit Adding GPS to your Arduino has never been easier. This kit comes complete with everything you'll need, including an EM406 GPS receiver and corresponding headers. With the example sketch, you will be able to locate your exact position within a few meters. The DLINE/UART switch switches the GPS module's input/output between Arduino's standard TX/RX pins or any digital pins on the Arduino (default setting uses pins 3 and 2 connected to TX and RX, respectively). Note: The DLINE/UART switch must be set to DLINE in order to upload code through the Arduino IDE. Kit Includes: 1 x GPS Shield 1 x EM-406A SiRF III GPS Receiver 2 x Stackable Headers 6-pin 2 x Stackable Headers 8-pin
