Dear all,
I might as well chip in then, since it's all gone
quiet!
I'm a biomedical engineer, and joined this list
because I'm going to be teaching bioinstrumentation
next semester. I thought building an EEG might make a
nice project for the students. We're just in the
process of buying a PCB mill, so I'm hoping to get
them to design, fabricate and populate PCBs instead of
using breadboard as they do presently.
One thing I wondered about was whether anybody had
tried using the sound card as a cheap ADC? I managed
to get some oscilloscope VB source code to read in the
data from the microphone jack, and I thought it might
be interesting to see how useful it is for
physiological signals. My main worry is that there is
probably a high-pass filter in there - anybody know?
Nice to meet you all, anyway!
Chris
