    Looks promising. The MD62 thermal conductivity sensor is used primarily to measure CO2 levels, but I came across a patent for its use with helium.

    Notes on the construction of my DIY Nitrox Analyzer. Pardon my lack of video shooting and editing skills. 1f603.png

    This is great! I already have an analyzer that I'm very happy with, but I'm going to build this because it looks fun.

    I believe I have most of what I need on hand, except the sensor.

    Thanks for sharing the project!

    Test the boost converter before using. The ones I got recently had a holding current of 50 milliamperes. You can use another boost converter running on 2 x AA batteries. Consumption is only 25 milliamperes.
