h2. Agenda

* Review the project installation

* Path forward

h2. Location

Boonshoft Museum

h2. Start-End Times

1600-1645

h2. Attending

From Dayton Diode: J., Joe

From Boonshoft: Liz, Jason, Kimberlee

h2. Discussion

* Review the project installation

** The voice over is for a "Cloud Chamber":http://en.wikipedia.org/wiki/Cloud_chamber

** The voice over is all new for the box so we can choose all accompanying hardware (button, speakers, etc)

** Voice over will be around a minute, so almost any size sd card will do

** Boonshoft already had a set of powered speakers for the installation (Dayton diode took them back to the space)

** Need power adapter for the Arduino (Dayton Diode will spec one, and then see if Boonshoft has one) 

** Boonshoft had a spare exhibit button to use (Dayton diode took them back to the space); still need to identify its source and part number for the bill of materials

** Exhibit behavior: 

*** button pressed when not playing a file, begin playback

*** button pressed when playing a file, do nothing and finish current playback

** Installing the button may be a little tight so will prototype function first, then demo at Boonshoft before designing final install (see pictures below)

** Boonshoft gave Dayton diode a 1 GB SD card for the project

** Liz wants to come participate in the build process, so keep her informed about work sessions

* Path forward

** Waiting on the Wave Shield to be shipped to Boonshoft (Liz will let Joe and J. know when it is in)

** Joe and J. will spec a power adapter in the mean time

** Joe and J. to coordinate build time with Liz so she can participate in the build

h2. Post Script

After the meeting, Joe and J. discussed possible upgrades for the project.

* Use an Arduino kit or bare embedded processor to save money

* Expand the number of buttons to allow for the playback of multiple sound files [J - To facilitate adding additional buttons, we could also connect the buttons with a standard cable/connector type (RCA maybe?)], this is just a matter of adding

** additional physical buttons

** additional sound files

** switching code to determine which button was pressed and then playing the corresponding file

* Video of a cloud chamber from J.'s visit to NY Hall of Science
