Auduino Software Synth

Tinker.it has published plans for building a software synthesizer using an Arduino. The Auduino uses granular synthesis to create a truly unique sound. The grain is constructed from two triangle waves. Each one has adjustable frequency, decay rate, and the repetition rate can be changed too. The Arduino just needs five potentiometers attached to the analog inputs and an audio jack on the digital out. You don’t have to use pots; you can use anything that varies the analog input between 0 and 5 volts. A video of the device is embedded after the jump. Continue reading “Auduino Software Synth” →

SketchUp Adds Dynamic Components

Google just announced the release of SketchUp 7. SketchUp is a 3D modeling program with a fairly robust free version. They’ve added quite a few features and the one that caught our eye in particular was dynamic components. Dynamic components have behavior specific to the object. The example in the video above shows a staircase changing the number of steps as its height is increased instead of distorting the overall staircase shape. The new version also allows for interaction, so model properties change based on user actions.

Google has always encouraged sharing of objects created in SketchUp. Thingiverse launched today with a similar emphasis. The site is built to encourage the exchange of plans for physical objects. It supports many different file types from plain images, AutoCAD dxfs to Eagle schematics. Many of the designs already posted are made to be cut out by a laser cutter or built by a 3D printer.

Javascript Drum Machine

js-909

[Cameron Adams] recently appeared on a panel about JavaScript libraries. He represented the hard working coder that still wrote everything from scratch. He wanted to make something mindblowing for the audience. He ended up creating the JS-909 drum machine entirely in javascript without relying on libraries or flash. While he makes no claims of compatibility, it certainly is a nice bit of kit.

LED Crazy DS

Adding LEDs makes everything better. Watch this video as a regular old DS gets turned into one of the most awesome things on the planet. A ton of LEDs were added, some to the body, some to an extra cartridge, some behind buttons. Parts are wired into the speakers, so you get nice effects to your music. We’ll bet the battery life suffers, but who cares. This thing is worth it. This was originally taken from Nico Nico Douga, which overlays the comments on the video.

Honeycomb Tire Won’t Go Flat

November 17, 2008 by 46 Comments

A new breed of tire has been developed that won’t go flat, even if it gets bombed. Resilient Technologies L.L.C. has started making these decidedly cool looking tires for the military. The honeycomb of stiff but flexible plastic acts as a shock absorber just as an air filled tire would. Unlike a normal tire, it won’t pop. You would have to completely destroy the tire to stop these. The article mentions that this isn’t the first of its kind. Michelin has made the “tweel” for industrial uses, but you may recall the video of the Audi driving around a course using them. If not, check it out after the break.

Full Fabric Soft Switches

When we created our backpack strap WiFi detector for Engadget, we embedded soft switches to control the device. They used two sheets of aluminum foil separated by a layer of foam with holes punched in it. [Plusea] has taken a similar approach but has replaced the aluminum foil with conductive fabric. The end result is a set of three soft buttons that can be easily washed. Have a look at the video of it in action below. Check out the followup project that uses the buttons to replace a scroll wheel. Continue reading “Full Fabric Soft Switches” →

Case Prototyping

[Deviant Ollam], lockpicker and beverage cooling contest host, was recently in Vienna, presumably for DeepSec. While there, he stopped by the Metalab hackerspace and checked out their RepRap rapid prototyping machine. You can see video of his visit above. He had them construct a custom fitted cover for the flash of his point and shoot camera. That’s what we love about rapid prototyping. Many of the projects we cover here solve a particular problem, but would never be considered commercially viable enough to put into production. With the availability of rapid prototyping increasing, hackers can start moving toward producing even more complex objects specific to their needs with a finish closer to commercial products.
