Hi everybody,
I recently got myself a 3d-printer. One of the first things i printed were star trek comm-badges.
There are rather complex and quick to print, which makes them great for trying out different slicer options. Also i think they are cool.
now i figured it would be even coler to have a badge that plays the signature chirping noise if pressed.
So obviously i need a way to play the saound sample. i know i could probably do it with a mcu and a 1 bit DAC, but i need to fit it all on 2cmx2cm pcb.
So i thought maybe there is a one chip solution to do this. I read about the ids2100 but i couldn't find a place to buy it from in the eu. also i read that the quality is crap.
So my question is do any of you know an ic for that, or shoudl i go with a mcu. i suppose i coudl fit an 8-pin attiny and a spi dac on the pcb. the attiny 85 has 8 kByte of flash. would that be enough to store the programm and about 2 sec of pcm audio? or is there al small formfactor mcu with integrated dac?
Thanks for your replies!
Cheers Psycho
