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
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
