Okay, so this is the most recent version of the electronic candle prototype, with the
proper board shape to fit in the plastic shell. What I have right now, you can't really see
it, but the only parts that are on the board right now is the audio circuitry. What you
have in the top corner is the microphone itself -- the port that actually picks up the sound
is on the bottom, so you can't see it, and then below that you have the op amp, and below
that you have a digital potentiometer which essentially acts as the automatic gain control,
so that the microphone (and therefore the candle) can react to both quiet and loud sounds,
and also keep it from clipping when the sound is too loud. Now, what I'm going to show you
next -- I've got that grey probe (the great big one) is an oscilloscope probe, and that
is watching the output from the op amp (the amplified output from the sound), and -- you
can see that it's amplifying my voice right now, and I think the scale is -- yeah, the
scale is really really high, so hold on. You can still see it picking up my voice, but
when I do this (cue Otsuka Ai's "Pretty Voice") let's see: Let's see if we can get this...
There we go, that's what I wanted. I figure there's no point in making you listen to the
entire song, But yeah, that's the first test of the AudioChroma electronic candle internals,
and it's working, so that just made my morning.
