MIDI Sequencer/controller

June 13, 2009 by 12 Comments

Reader, [Lennon Luks] made a really slick  MIDI sequencer/controller for his senior design project while studying at Western Carolina University. It has a grid of 64 LED buttons, 8 knobs, and a display with navigation buttons that allow him to sequence tracks with or without a computer. The controller is based off an ATmega644 and is programmed in C. [Lennon] clearly explains the inner workings of the project in detail on his website and has included a good number of pictures. [Lennon] made a nice video of the project which can be seen after the jump.

LED Buttons

For their final project in ECE 4760 at Cornell, [Christina] and [Joe] made a small single octave keyboard using LEDs as the input. They used a total of 63 LEDs to make the keys. Each key consists of 9 LEDs, with the center one acting as a sensor. When you lay your finger on it, the light reflects off of your finger and is picked up by the center LED. An ATMega 664 runs custom code to play a sound. You can find out more details about the construction as well as download the source code on the site. You can also download an example movie of it in action ( 7MB .mp4)

Felix’s Machines

Ok, we know you’re going to get mad, there’s virtually no information on the technical side. But the music was so pleasant, and that’s rare.  There’s an interview with Felix, the creator, where he discusses his goals and ideas behind the project. We prefer just to sit and watch though. If you want to make something similar, there were some technical details on a mechanical drum recently.

Bohemian Rhapsody On Old Hardware

Here’s another junk music performance to add to the list. [bd594] put together this rendition of Queen’s Bohemian Rhapsody on assorted computing equipment. The lead piano sound is from an Atari 800XL. Lead guitar is a Texas Instruments TI-99/4a. An 8inch floppy plays bass while a HP ScanJet 3C covers the vocals. He had to dub the scanner four times to get all of the vocal parts. He wanted to use four independent scanners but the prices on eBay were forbidding. The use of oscilloscopes to show the wave forms in the video is a nice touch. Check out our post about Radiohead’s Nude for more examples of this.

Wiitar, A Build Log

wiitar

[Ozan] sent in this build log from when he made a Wiitar. As you can probably guess from the title, it’s a guitar combined with a wiimote. He has completely gutted the Wiimote and installed the internals in the guitar. Some toggle switches were mounted to control the button states on the Wiimote.  This is a pretty useful setup as you can use the Wiimote data to control effects on the guitar. We’ve actually seen a very similar setup before. [Ozan] has included the build log, as well as a simple glovepie script and a sample effect patch.

Hard Drive Speaker IPod Dock

This looks like someone watched the Obsolete Technology Band, and had to have one of their own. It appears to be a dock, driving several different sizes of old hard drives. While the concept isn’t new, we thought they did a decent job of putting the whole display together. It could be fun to have that mounted on our wall, waiting for geek friends to impress.

Beat Boxxx And Speak To Me/Breathe

[Steve] is in the MFA Design and Technology program at parsons, and as part of his studies, has built a couple really interesting projects. First, the Beat boxxx, as seen in the video above, is an 80’s retro looking portable beat looper. You create and loop your beats at the time of playing using simple hand gestures. The look is great, for those who enjoy cardboard and magic marker, though we think some tonal variation and possibly a wider pitch variation would really make this fun.

His second project is Speak to Me/Breathe. This project was meant to be a commentary on security in our daily information. He is visually displaying the braille symbols to spell out his emails. If any person were to spend the effort, they could decipher his emails. The finish on this project is quite nice, you can see a video of the display after the break.
