Ended up getting a pretty good deal on a portable compressor that a number of sailors have on their boats, so I'm confident it will work fine for me. That'll arrive in a couple weeks or so.
In the meantime, I'm looking into Nitrox sticks. Anyone found "good" examples of complete systems? I'm talking parts list and assembly from the O2 side to the air suction to the compressor? Reading over the oxygen hackers manual I'm seeing 3 main parts:
1. Intake (the stick itself) with connection to the compressor. This is the PVC or similar piping, baffles, O2 connection at the top/start of the intake, piping and associated tubing.
2. O2 supply. This can be as simple as a regulator, valve, and tubing going to the nitrox stick.
3. Controls/safety. These seem to range from reading an O2 sensor on the end of the stick and making manual adjustments with no automatic safety system all the way to digital control systems regulating O2 flow.
1 and 2 seem pretty straight forward (assuming you follow the basic safety recommendations from Harlow's book). For 3, I'm thinking a DIY O2 sensor with solenoid trip valves in the O2 line. Ideally, a compressor trip AND/OR a high O2 reading would trip the O2 solenoid. However, I haven't found plans for something like that specifically. Has anyone developed that and have a walk-through or suggestions?
