Audio Breakout Box For MacBook Pro

June 21, 2010 by Mike Szczys 28 Comments

[Billy] wanted to use the audio connector on his MacBook Pro for input and output at the same time. He knew it could be done because Apple sells headphones with built-in microphones that work with the computer. He set out to build a breakout box so that he could connect the components of his choice to the single port. Using a scart-RCA adaptor box he scrapped the scart plug and wired the RCA jacks to the Apple headphone wires. He can now patch the pickup of his guitar to the mic connector, send it through the MacBook, and run the output back to his guitar amp.

Velosynth Annoys Those Around You As You Ride

June 18, 2010 by Mike Szczys 43 Comments

We’ve always put stock in ‘the quieter the better’ when it comes to road bikes. You’ll find this truth if you spend 100k on the back wheel of someone with a sqeaky rear derailleur. But apparently the folks at Effalo never learned this lesson as they’ve produced a bike computer that generates noise as you ride.

Perhaps it just takes some ingenuity to turn this into a beautiful music maker along the lines of the Force Trainer hack. No problem because the velosynth is a hackable design. The case was made with a vacuum form and inside you’ll find a bunch of small breadboards. The JeeNode, which is an Arduino/Xbee combination, serves as the heart of the device by taking speed and acceleration data from the bicycle wheel. From there it is passed on to various modules, Bob’s your uncle, and sound comes out. Check out their sales pitch after the break and if you’re starting to get some ideas about using this check out the open source info they’ve provided.

Vuvuzela Removal

June 15, 2010 by Caleb Kraft 41 Comments

We’re hearing complaints everywhere about the noisemakers called Vuvuzelas during the world cup. Whether you are a fan of the sport or not, you can appreciate when a fellow hacker gets annoyed and start hacking. [Tube] has created a software filter that manages to remove the sound of the Vuvuzela from the videos. He shares the process of how it was all created, using Logic Express and a Mac mini (Google translation). Maybe this will also provide some relief from the constant stream of Vuvuzela whining as well.

Massive MIDI Station Ditches The Monitor

Who need’s a touch screen when you’ve got 800 inputs each backlit with an RGB LED? This impressive controller was built by Ander for use in his performances. He did it with the intent to get rid of the computer monitor in his setup. We think there’s something to be said about that. It seems weird to go to a performance and see the artist staring at a screen the whole time. Unfortunately we don’t have too many details about the hardware but we can tell you that he’s using Ableton Live on the software side of things.

Wiimote Controlled Ruben’s Tube

June 11, 2010 by Jakob Griffith 13 Comments

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.

This Wiimote Rubens’ tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

DMX Keyboard Display

June 10, 2010 by Mike Szczys 10 Comments

This keyboard display has an RGB LED for each key that is addressable through the common stage lighting protocol, DMX. The project video, seen after the break, does a good job of walking us through the concept. By using a MIDI to DMX converter box [John] can show MIDI signals coming from a keyboard on the appropriate key of the display. By further monkeying with the firmware in the converter box he shows a plasma effect on the whole keyboard, making the corresponding light for each pressed key pop out in bright white. Jump to about 3:45 to hear and see “Sweet Child o’ Mine”.

This isn’t the first time [John’s] been caught with a slew of blinking lights. He helped create the giant LED Christmas tree that brightened up our holiday.

Adding Compact Flash To An Old Sequencer

June 5, 2010 by Mike Szczys 32 Comments

[Shoji] has a beloved sequencer that went out of production ten years ago. Unfortunately the storage options are also 10 year out-of-date as SCSI is the stock option for storing his loops. Using a series of adapters he added Compact Flash storage to his Akai MPC-2000 Classic. The board has a connector for 25-pin SCSI which he wired to a 25-pin to 50-pin SCSI adapter. From there he connects a SCSI to IDE board, and then an IDE to CF. Subsequent versions of the Akai Classic have floppy drives in the front left corner so he used this method to mount he CF slot. Now he’s got plenty of storage with very little change to the appearance of the looper.
