RE: Audible Notice of casting of a vote



 
If you know of a small internal speaker can project 20 feet, then we should just replace the existing internal speaker with that one.  I am no EE, but anything that loud is going to need amplification circuitry.  The SH3 has two 8-bit DACs, and we are only using one of them.  In addition, the HD64465 has a 12-bit DAC that is unused.  There is no need/reason to mess with a F series PIC, interface with it, etc.

I say we create a seperate internal speaker that snags some audio (or have the software send a call to the PIC we have now placed on the board) from the onboard audio processor,,from here we can run it through a PIC of some sort (F family being enough) and use pulse width modulation, this would give you a wide range of sounds and tones that we can create.  You can create a tone with a small internal speaker and a PIC loud enough to be heard from 20 feet away.  Also, this would require very low power, and wouldn't interfere with the VIBS external speaker jack.

Interesting.
 
The AVTS has an internal speaker, but there is a hardware problem with the current sound system so it is basically inaudible.  But even if that were fixed in a later release board rev, its doubtful that the little speaker would project 20".  We can plug an external speaker into the VIBS audio port, but the fun question here is how to power it and how to stop voters from borrowing them.  In short, I defer to Global's hardware development department.
 
On the software front, playing any sound they like when the ballot is cast will require exactly one line of code.

Posted on behalf of Robert Pickett:

 

This is a requirement for the State of Louisiana.  We are in the process of bidding on a statewide voting system.  Robert has been asked to demonstrate this capability by Wednesday, November 21, 2001.

 

Provide an audible signal that the voter has cast their vote.  The audible signal should be heard from 20 feet.  This would require a noise to be played once a voter has pressed the “Cast Ballot” button.
