Abort, Retry, Hack? » Blog Archive » OpenLase: open realtime laser graphics. Update: see this post for hardware info and also a new GL laser simulator for those without hardware. First of all, as I’m sure everyone knows by now, I’ve been working on hacking the Kinect and writing open drivers for it. There’s a website for the community and a Git repo with the code, and it’s working fairly nicely by now. With that out of the way, here’s a project that I’ve been working on on-and-off for the past year or so. I’ve been interested in laser scanning and DIY laser projectors, but I couldn’t find any good open source software to drive them.
DIY laser projectors commonly use sound cards as DACs. Since we’re converting laser images to audio data, why not just treat the laser data as audio in the first place? On a typical setup, you’d have two processes running on top of JACK. On the other hand, you have whatever picture source you want to use. There’s one part of the demo made it into the OpenLase distribution as a separate example: tools/trace.c. Camera trick lets you see sound waves in falling water.

Las 50 empresas más innovadoras del 2013, según Fast Company. Para sorpresa de muchos, Nike se transformó en la empresa más innovadora del 2013, según el ranking publicado por Fast Company. Más atrás aparece Amazon y Square, en un listado de 50 compañías donde se destaca la ausencia de Facebook y Twitter. Según publica la revista, esta guía anual analiza el estado de la innovación en la economía, con los negocios cuyas innovaciones están teniendo el mayor impacto a través de sus industrias y su cultura en su conjunto. Respecto al primer lugar de Nike, la publicación destaca que durante 2012 la firma concretó dos golpes al mercado. La primera es FuelBand, una pulsera de US$ 150 electrónica que mide los movimientos de todo el día. Desde un trote hasta la caminata al trabajo. La otra innovación es la Flyknit Racer, zapatos de peso pluma que se sienten más como un calcetín encima de una suela. Producir una sola de estas innovaciones en un año determinado es una rareza para cualquier empresa, especialmente una con 44.000 empleados. 1.- Nike. 5. 6. 7.
Non-Inverting Amplifier. The amplifier is the first step in the circuit, it increases the amplitude of the signal from around + or - 200mV to + or - 2.5V (ideally). The other function of the amplifier is to protect the audio source (the thing generating the audio signal in the first place) from the rest of the circuit. The outgoing amplified signal will source all its current from the amplifier, so any load put on it later in the circuit will not be "felt" by the audio source (the microphone element in my case). Do this by setting up one of the op amps in the TL072 or TL082 package in a non-inverting amplifier configuration. The datasheet of the TL072 or TL082 says that it should be powered with +15 and -15V, but since the signal will never be amplified above + or - 2.5V it's fine to run the op amp with something lower.
Wire up your +V(pin 8) and -V(pin 4) to the op amp. The following equation describes the relative amplitudes of the signal before and after the non-inverting amplifier: Ever Dry | UltraTech International Inc. Ultra-Ever Dry does NOT dry clear! It cannot be used on automobile windshields and obscures visibility through glass. Ultra-Ever Dry is a superhydrophobic (water) and oleophobic (hydrocarbons) coating that will repel most water-based and some oil-based liquids.
Ultra-Ever Dry uses proprietary omniphobic technology to coat an object and create a surface chemistry and texture with patterns of geometric shapes that have “peaks” or “high points”. These high points repel water, some oils, wet concrete, and other liquids unlike any other coating. Ultra-Ever Dry has vastly improved adhesion and abrasion resistance, compared to previous superhydrophobic technologies, allowing it to be used in applications where greater durability is required. Anti-Wetting- The superhydrophobic coating keeps objects dry. Water and many other liquids are easily repelled. Prototype - Coin Acceptor - Programmable (6 coin types) - SKU: MCI-PRT-01212. Description Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take up to 6 different kinds of coin! Whether you're building your own arcade cabinet or just charging admission to your house, this programmable coin acceptor makes it easy to monetize your next project.
The sensors in this coin acceptor use the thickness, diameter and fall time of the coins to identify them and it's fully programmable so you're not limited to any particular type of currency. Simply use the buttons and 7-segment display on the side of the unit to select a coin profile, insert a bunch of coin samples (or the same one, over and over) then designate the value.
After you've programmed the coin profiles, simply read the serial output of the coin acceptor and it will tell you the value of each coin as they're inserted. Features Documents Share Product.
