Jason,
Nicely done!
Where do you mount the sensors?
How does the counterlung spring affect the breathing? In its original terrestrial application the BP-60 uses the spring to maintain positive pressure in the loop. Just wondering how this works out in different orientations underwater.

The sensor are mounted on the top cover of the scrubber (which is a thin stainless steel plate) where there is a significant space between the top of the scrubber and the stainless top cover. I am not home at the moment, or I would add a picture. The spring works fine for this application- it is not perfect, after four hours my cheeks are a little sore as there is a slight negative pressure at the mouthpiece- Not really enough to cause a problem breathing, just slightly uncomfortable. I have a bunch of slightly thicker springs and I will experiment with trimming them to the proper length to increase the spring pressure. This will make the inhale just a bit easier and the exhale a tad more difficult. If I didn't already have these springs that happen to be exactly the right diameter I probably would not bother, as it really is not that noticeable- and still much easier to breath than the Kiss.
