For those of you considering an O2 system and are interested in a DIY version, here is my current setup. I'm sure this has been done before, if so then another take on a working system.
Parts:
Cylinder, Alum. Type D, CGA870, 1502ED (1) New $90
Cannula, Salter Labs 16SOFT-4 4 Foot $10 for 5
Drive CHAD® Evolution™ Electronic Oxygen Conserver (1) $200
LINE2design Oxygen Cylinder Sleeve Bag $25
The Conserver is the heart of the system and claims to increase the duration of a bottle by 5X. The device can be set for 1 to 6 liter "equivalent" flow and seems to work well in the plane. Notice that the company sent a "Motion" version which adjusts for user movement, not something you need in the plane, but easily bypassed.
It's mounted on the aft side of the flap drive support in the cargo area with two velcro straps. Bit of a challenge to reach in flight but doesn't flow O2 unless you're breathing, so no foul starting the flight with it turned on.
I also added a finger SO2 meter (find those anywhere for $35) and a CO detector:
AV8 Inspector AV8-CO-01 Carbon Monoxide Monitor for Aviation $110
The local dive shop with refill the bottle for $25 and the welding supply will likely do it for a few bucks less (the dive shop was able to fill the CGA870 fitting just fine).
Considering the cost of off the shelf units from other suppliers, this is a reasonably priced system that works well.
Cheers
