| SPG Recommendations/ DIY LP Inflator Hoses? / New ppo2 monitor
What is the general consensus regarding SPGs?
1. Mini "Button" style pony gauges.
2. Two normal SPGs
3. Verify before you dive that you have enough gas, and don't bother taking SPGs
4. Some other combination
Also, I've dove my homebuild enough now to feel the need for clean/custom hose routing. I need some unusual length LP inflator hoses to do this. Is there a source for reusable hose ends; I'm likely to need a new hose length each time I make a mod?
I'm working on a compact PPO2 handset to replace the bulky panel meter version I'm using now. It's less half the size. I looked into the Picaxe chips that Tom Rose mentioned, and came up with a digital PicAxe design for monitoring ppo2, but I'm still convinced manual O2 addition is the way to go. Still waiting on some smt components before I can get it in the water...
I found some GREAT multi conductor cable as long as I don't run into noise problems. It's listed on McMaster as "continous flex" cable. Is very flexible and is much more durable then the SJOOW cable I've been using. |
