Yeah, they're growing them right on the chip!

I'm all for simulators, but I'm really itching to play
with real data. Does one have to get a PCB board made
to try out the current HW, or would it be reasonable to
plunk those parts down on soldered breadboard material?
I do that with lots of other circuits, but they are not
nearly as sensitive to noise.

Cool, you've tried making them! I will check that out.
Can you share a bit on results: did you try feeding
them into a second stage amp and are you getting some
better results than passive electrodes? I assume that
you are doing ECG not EEG with those, is that right?
