DIY Book Scanning | A forum dedicated to book scanning, open source, DIY digitization. A bright idea to help bike riders be seen and not harmed Designer Wouter Walmink:"One of the things we wanted to do was to make a helmet that was more exciting to look at". WOUTER Walmink never considered wearing a bicycle helmet until he moved to Melbourne a year ago. But after pedalling through the city's hectic streets, the Dutch designer realised he was going to need a helmet - so he set about making a better one. The result is the LumaHelm, a flashing headpiece with 104 multicoloured LED lights that illuminate like indicators when a cyclist tilts the head left or right. ''One of the things we wanted to do was make a helmet that was more exciting to look at,'' the 28-year-old says. Advertisement The LumaHelm is based on a standard helmet fitted with lights powered by AA batteries and a sensor that measures movement of the cyclist's head. An Arduino microcontroller placed in the cyclist's pocket translates those movements into light patterns. Mr Walmink says his invention could improve cyclist safety. henrietta.cook@theage.com.au
Amazing Pendulum Wave Shadow Effect Computer parts Skylines Italian artist Franco Recchia gives new life to computer parts by reusing them into nice miniature city skylines ! ++ More information at FRANCO RECCHIA – metropolitan artist website ! Idea sent by ! Epoxy Gel Coat Gelcoats are special resins that are designed to form the first surface of a composite mould or part. Gelcoats are generally applied as a thickness of 0.3-0.7mm and are specially formulated to provide the part or mould surface with properties such as resistance to UV (ultraviolet) degradation, hydrolysis or osmosis (where water is absorbed into a composite over considerable time). Gelcoats also include thixotropic additives to make them thicker and more able to stick to inclined surfaces of moulds. Epoxy gelcoats are based on epoxide resin and polyamine hardener (just like epoxy resin) and should be used when making parts using epoxy resin , if a gelcoat surface is required. Gelcoats are applied to a mould surface and allowed to cure to a certain point before the first layer of laminate is applied. Tooling Gel Coats Tooling gel coats are specially designed to provide a highly polish-able and durable surface to epoxy based moulds.
Exhibit Services » Blue Sky | Exploratorium Blue Sky demonstrates why the sky is blue. This is a phenomenon called “Rayleigh scattering.” A clear tube is mounted in front of a light source with the light shining into the end of the tube. The light scattered by the tube looks blue near the projector and gets progressively yellower further down the tube. A very orange “sun” emerges from the tube and is projected onto a screen on the side of the exhibit. Educational Resources Explainer Videos For Information About Exhibit Sales: Global Studios
Power-Up Arcade Light Switch Plate 10 Interesting Futuristic Materials 1. Aerogel Aerogel holds 15 entries in the Guinness Book of Records, including "best insulator", and "lowest-density solid". 2. Carbon nanotubes are chains of carbon held together by the strongest bond in all chemistry, the sacred sp2 bond, even stronger than the sp3 bonds that hold together diamond. 3. "Metamaterial" refers to any material that gains its properties from its microscopic structure rather than bulk composition. 4. We're starting to lay down thick layers of diamond in CVD machines, hinting towards a future of bulk diamond machinery. 5. Diamonds may be strong, but aggregated diamond nanorods (ADNRs) are stronger. 6. Amorphous metals, also called metallic glasses, consist of metal with a disordered atomic structure. 7. A superalloy is a generic term for a metal that can operate at very high temperatures, up to about 2000 °F (1100 °C). 8. Metal foam is what you get when you add a foaming agent, powdered titanium hydride, to molten aluminum, then let it cool. 9. 10.

Currently we have our solo show in CLASKA Gallery&Shop “DO” in this hotel. In addition, we are showing a wide range of our products such as “CMYK”, “Kitchen Blocks”, “softblock”, a new released product “clopen”, as well as bookends made by wood left over from the making of koloro desk, which is a project in progress.
