Has anyone poked at the Shearwater CANBus protocol? I have a Prism2 and always wondered about something like a DIY NERD2 that only has PPo2 and depth information on it. There are some cheap OLED Color screens out there that are tiny. Microcontrollers with CANBus are cheap. The optics side is a...

RGB LASER show projector built to fit a recycled Ikelite Sony Camcorder Housing. It was raining all day so the quarry was fairly cloudy. I definitely need to change a lot of the patterns after seeing how they look in the water. 500mW total (R+G+B) (Class IV Laser output) so not eye safe...

Unfortunately the Shearwater electronics used on CCRs lack any audible (beep) or mechanical (vibrate) alert when things are in the red. The HUD is in your FOV, and should be blinking red but I wonder if it's possible at large hours to grow accustomed to it and miss it. No idea why Shearwater...

I am a new Prism2 diver (50 hours or so) and my unit has the BOV plumbed to the dil tank. Are you talking about plumbing the BOV to the bailout? Using a quick disconnect or something? Usually the training process involves handing off and/or ditch + retrieving the bailout tank.

Hello! I ended up buying one off of eBay. So far, I've built the projector and managed to finagle enough battery power to drive the electronics. There is a part I ordered from China that got lost by the USPS, so I had to double up the batteries. I will post about it over in DIY soon. I took it...

The Prism2 counterlungs are strong enough to act as the harness if you wish, but then when you hang a bailout from the D-rings on the counterlungs it hangs really low. I ended up adding a harness back on mine. Another thing you can look into is if the electronics have the 3 LED HUD or the 12...

Fairly new CCR diver, but an electronics geek. Finished Prism2 cert last summer, I am at maybe 30 hours now. My original DGX (AI?) were due for replacement so I picked up a set of 3 from OxyCheq. First, no born on / death by date printed on the label unlike the DGX ones. This could be...

Fairly new CCR diver. Experience is a few dives on OMG C96, one Optima dive and I have a Prism 2 OTS CL Shearwater canbus electronics. Good: - Common o2 sensors - Pretty decent support market for it - Hollis replied to any emails I sent - The clear canister lets you see if there is water...

Old thread, but I ran across a posting from a family member with more details on this at divermag.com (Rebreather Fatalities - DIVER magazine.) Turned up in a google search, IIRC it was two rEvos. I'm adding it to this thread for the sake of keeping records together and because it provides more...

It's the future and here to stay.

Medical? Open circuit or CCR?

Looking for an underwater housing or two for other geek projects. I'm looking for large underwater housings for cameras that people no longer care about. Instead of making my own waterproof box, I figure I can re-use something like the Sony MPK-TRB or similar. Old Sony Hi-8 or 8MM. Any vendor...

Home page of Blue Octopus Scuba (a local shop to me) says it was one of the co-owners (M. Wright) :-( Welcome

Interesting presentation. I knew a good bit of the info but did pick up some interesting stuff. With regards to these solid state sensors from Poseidon: Poseidon It says a dye reacts to the O2 and there is color change. Are they sampling this with a CCD and a light source or something? How...

I think Coral Edge Adventures is open like Fri/Sat/Sun now or something. It's on their facebook page. From May 20th: "Coral Edge Adventures is starting modified hours on Friday May 22 as follows: Friday 10am to 3pm Saturday 10am to 3pm Sunday 10am to 3pm We expect these hours to expand in the...

Went past two weekends to Lake Phoenix. It was nice! Water is warming up. I think it was lower side of 60s at 30ft and 70 at surface. Didn't download my computer yet so don't have it with me. I found out that the fish will chase a laser pointer like a cat. Pretty odd.

Hoping to get out to Phoenix myself this weekend to start off the 2020 Coral Edge Adventures runs Millbrook Quarry. I don't see anything on their calendar but that doesn't mean they're not doing training. Not sure what is up there. AFAIK no Juturna until one of the J months at minimum? Dutch...

Ah yea. Contaminated fill?
