Music: Dimitri Shostakovich, Suite for Variety Orchestra, No. 7 (Waltz 2). (This suite is erroneously identified also as the "Jazz Suite No.2" because it was first performed in London in 1988 under the title "Suite for Jazz Orchestra No. 2", and Decca published an album in 1991 called "The Jazz album" with excerpts of this suite.). This is a microfluidic equalizer. Each of the 7 microvalves (bottom of the image) opens when the music volume exceeds a set threshold in a given band of frequency assigned to that microvalve. The script that converts the music into on/off signal for the microvalves is written in LabView. The microvalves open microchannels containing dye. Flanking the microvalves is a constant background flow of colorless water, which keeps the dyed fluids focused in separate streams. Due to a microfabrication defect, the microvalves leak fluid even when closed, but that produces a pleasant artistic effect.

We are working on improving the microvalves so that they will have a better dynamic range. Right now they leak at rest, so they "smear" the short beats. It is easy to fix. Thanks for your comments!

The effect is difficult to see, so consider using this setup with more dynamic music such as chiptunes or breakbeat. (Lots of chiptunes are CC BY-NC-SA licensed.)
