  After a few setbacks and trying out various combinations of components, I finally have all 16 pumps being controlled from this Arduino! I ended up getting a new Arduino that has enough pins to drive the relays directly instead of going through a serial expander board which was causing me problems. I also abandoned the Darlington arrays in favor of these relay boards that have all the relay isolation stuff done for me. This also keeps the 5v Arduino and 12v pump power supplies completely separate, which I feel much more comfortable about. Next step is to mount this into my cabinet and hook up the tubing! Then time to get to work on the recipe database! #barbot

• Day 47 - Launch

  Day 47. Today I wanted to use a bunch of samples from NASA shuttle launches. I started by finding a countdown I liked, and then grabbed samples from a bunch of different NASA launches to overlay them. I retimed the countown to fit the beat, and took some liberties with the order of some of the sounds, like adding the mic chirp in places it wouldn't normally exist. I used a recording of a shuttle launch as the foundation. The video is an assortment of clips I found on the Internet Archive from various NASA missions.

• Day 50 - Voices

  Day 50. I'm officially half way done! This one is inspired by Loreena McKennitt's "The Mummers Dance". I used a few different samples of Bulgarian voices from the EastWest "Voices of Passion" set. You might also notice the reverse-piano sound a couple times. I used a mix of the drum track generator plus myself playing the bongo track on the keyboard to get a good mix of percussion.

  Day 52. The goal of this one is background music for a trailer or at the end of a TV episode. The build-up and tension at the end is what I've been noticing TV music does, where it resolves but doesn't quite resolve. The video is from morrisey.com's drone footage of the Oregon Coast.

  Day 46. The time signature of this one is 15/8. Basically each phrase has a half beat less than what you'd expect from 4/4, or a half-beat more than 7/4. I did a lot of EQ separation on each instrument to really isolate each from each other.

• Day 56 - Concerto No. 56 in Cm

  Day 56. For today's song, my dad chose the instrumentation and style, and I had to see what I could come up with. He gave me "horns" and "concerto". So I started by studying the structure of concertos. A concerto typically features a single instrument soloist, with an orchestra or piano backing it up. They typically start out with an "exposition" from the instruments other than the featured instrument, introducing the theme. Then the second exposition features the soloist introducing the theme again. This is followed by a "development" section, featuring the soloist, usually in a different key, which ends by building up on the maj7th chord to a coda section which repeats the original theme in the tonic. My challenge was to fit all this in under a minute, so I basically have one phrase per section. I started by using the motif from Day 3 and building everything up around that. The very last phrase is basically the Day 3 song at the end.
