wow.. how did I miss all these posts? (dang email notification!!!!)
1.) thanks for the link.. (I gotta figure out to rip the audio form the YT vids now) =(
2.) files size for sound.. unlimited more or less.. I mean.. we'll never fill up the SD card with 'this' project..
I doubt there will be many (any?) more sounds then just the pew-pew sounds...
maybe a boot-up sound when its powered on?.. and an 'empty' sound..
but thats up to code.. we can add more sounds how we like.. but how to we trigger them>?
we have VERY (very) limited space!! to the point where I am having trouble find space just to solder pads for the 1 switch we have now and the battery/speaker pads too!
Im gonna try to work it out that we can do more than 1 activity/action with the same 1 switch..
press makes pew sound
keep pressing (and when counter runs down).. it makes 'empty cartridge' sound
when empty.. hold button down for a couple seconds to 're-load'
during shooting it will count down and dim a green led every x shots.. until all leds are off and cartridge is empty..
thats my current plan of action at least..
current status of project is this:
have tested everything on a 'real' Arduino (full blown dev board)..
and its 'working'..
cons: the audio is NOT great.. being no room.. means no low-pass filter.. and no amp.. so its more along the lines of a TOY quality audio.. (if we are 'open' to hiding a few small electronics on the lather band of the wrist straps. then we can explore more options..
already working on porting to the smaller, minimal version we will be using for testing.
1.) have a breadboard demo mock-up all set.
2.) have it ready for 3.3v / 8MHz internal clock (minimal components) set-up
current 'bug' is getting the SD card to work with this minimal 3.3v/8MHz internal clock Arduino set-up...
once that get figured out (if it can be).. I'll post another update.. get some feedback/polls.. and we'll order some PCB's
just an update!..
