Hi Charles,

I'm considering the plausibility of a little hardware project that would
turn a Freerunner or any computer with an adequate sound card into a mimio
[1] device.

Any input from the community?
Assuming I've understood this even
Here's another approach:
Why not use two freerunner on different locations which do have one ir
input attached. They synced the clock with ntp and both of them save the
time difference between mic and ir data. You know the exact location of
both and you could sync the data over wlan/gprs and

You probably want to look at these two. The main limitation is that you've
only got one input channel via the jack, but you might be able to get round
that using the mic switch detection.
I incorrectly assumed there is

All the Freerunner would be needed for is processing the input of the
mic-in. The freerunner microphone isn't used. Imagine a stick with two
microphones glued 400 cm apart and connected to a audio cable. There is more
to it, but that's pretty much what
why not try this technique through the bluetooth ?

Can I
record audio from the mic input and the built-in microphone at the same
time?
Yes. Route headset (mic1) to the left ADC and handset (mic2) to the right
ADC,
then set the record mode to stereo.
This is good news.

I think I will investigate this option. I've thought about it before, but
couldn't find any Linux
What is the highest sampling rate I can get from the audio jack? What is the
frequency range?

The principle is an expansion on the way
The following two equations would give the position of the dry erase marker
relative to point A. (I may have mixed up my positive and negative
directions somewhere, but you get the picture.)
d_Ax = (v_sound)sqrt(t_A^2 - t_B^2)
d_Ay = h - (v_s^2)(t_B^2 - t_A^2)/(2h)
