• Music synthesized from the Game of Life
  [vtol] has built a very elaborate system of electronic sound machines, which can be patched together in various ways in order to create all sorts of sounds and sound effects. The modules range from simple noise synthesizers to pitch shifters, sequencers, and effects processors. The most recent addition to his synthesizer system is a matrix [...]
• Arduino and Open Sound Control without an Ethernet shield
  Open Sound Control (OSC) is a communications protocol that can be seen as a modern alternative to MIDI. It’s specifically designed to play nicely with network communication systems. The problem with using it along with Arduino-based gadgets is that you then need to use something like an Ethernet shield to provide the network connection. [Liam [...]

  Magnified glasses A late hacking session, and parts-on-hand came together as the inspiration for [BadWolf's] magnified glasses with LED lighting. Pendulum Printer This orb, when swung like a pendulum, prints images by dropping ink out the bottom. A processing sketch works in conjuction with a Wii Remote and an IR LED in the orb to [...]
• SudoGlove gets a big software upgrade
  [Jeremy Blum] recently finished writing a couple of software packages for his SudoGlove system that turns it into a music controller with a lot of features. We’ve seen the hardware in a previous post and as a goal for this iteration he decided not to alter the hardware or the firmware controlling it whatsoever–making this [...]

• Automatic trigger for lightning photography
  [Vicktor] has always been fascinated by photographs of lightning and decided to try his hand at capturing a few strikes on his camera. Every time he attempted it however, he didn’t have much success. Instead of trying to operate his camera manually to take the images, he decided to build a lightning trigger that would [...]
• WiFi radio plays your tunes in style
  Instructables user [Jan] likes listening to music while hacking away in his workshop, but listening to the same CDs gets tired and boring after awhile. He contemplated listening to streaming audio over the Internet, but hated the idea of needing a computer around at all times. After a bit of reading, he found some information [...]
• Kinect Two-fer: MoCap movie and robot control
  It’s no mystery that we like the Kinect around here, which is why we’re bringing you a Kinect two-fer today. We have seen video hacks using the Kinect before, and this one ranks up there on the coolness scale. In [Torben's] short film about an animation student nearly missing his assignment deadline, the Kinect was [...]
• Hand-built car made almost entirely from scavenged parts
  So you’ve swapped out your car’s motor or added new tranny. Perhaps you’ve rewired your ancient VW bus from 6v to 12v. Do you think that makes you a car expert? [Orismar de Souza] might beg to differ. The homeless Brazilian native has spent the last four years of his life building a car from [...]

  [Valentin] is the MacGyver of model rocketry, building a small rocket out of three items many people have hanging around the house. Cat litter, matchsticks, and a ballpoint pen are the raw materials that he rounded up before setting to work on the build. The housing of the ballpoint pen will act as the body [...]
• Antique Light Bulb Organ
  Add a retro light show to any MIDI instrument with this Antique Light Bulb Organ, twelve 30 watt antique style light bulbs correspond with the 12 notes in an octave with a simple on or off action. The organ is also monitoring the pedals, so the lights will stay on as you use the sustain. [...]
• Bubble Display
  As hackers we have come up with some pretty wild and unique ways to display data, but that never stops us from creating even wilder ways such as this Bubble Display. Inspired by a Hackaday article called Liquid Display the bubble display started out as a one column lexan tank so the team could check [...]
• Interactive dice game pits man against machine
  While most dice games are based on luck and chance more than anything else, [Mike] decided he wanted to create a dice game that took a little more skill to play. He built a replica of a game found in Ian Stewart’s “The Cow Maze”, a book of mathematical stories and puzzles. The theory behind [...]

• More high voltage experimentation with a flyback inverter
  [Electorials] actually makes working with a flyback inverter sound rather easy. This comes hot on the heals of the huge high voltage collection we saw the other day, but slows way down in the presentation of information. This makes the project very approachable for the newbie, especially considering that the majority of the testing is [...]
• Redbull sends marketing doodad to hackerspace using an open source product
  Posts Looks like Redbull is harnessing the power of open source hardware to market their product to hackers everywhere. We’d say that it worked because here we are, posting up some free advertising for them. It seems that a rep for the company dropped off a package at a hackerspace in LA called Null Space [...]
