I swear there was a similar issue a while ago (I probably read it on here) where someone gave their kid a pony that was full of argon for drysuit inflation. They were able to revive though, but it was a close call.

Ah interesting! The thing is, I don't want to do anything to hurt the integrity of the connectors and I would be afraid even thought he wire is super thin, I could end up deforming the walls of the pins. And then water could get in. Also, the connectors disconnect with a solid pop noise which is...

Started trying to poke at this last week. So far I've established pin #1 (which is the center bottom pin on the 5 pin connector) is tied to system ground. The next issue I have is the connectors used. They're pretty sexy, but in my mind I could back it out part way and access the contact to...

Video of the housing I ended up with in action. Will get better video this summer when Lake Phoenix warms up.

Hello! I did end up finding one of these housing and reused it for a laser projector. You should be able to drop any kind of camera in there, something more modern and digital. I would make sure that it is waterproof first. In my case the housing didn't have the seal in the proper position and...

I tried to RX the transmissions while troubleshooting my Perdix AI xmitter. I was using an ICOM pro 756 II HAM radio and I saw nothing, even with the end of the coax up against the transmitter. It has a spectrum analyzer type function... nothing. The 38KHz frequency is at the very bottom of what...

I took mine (Prism2) apart a while ago when I couldn't really get info on the architecture of the system. As I recall (I posted pics on here actually), the o2 cells feed two separate PCBs. One has the ADC for the HUD, the other has the ADC/solenoid driver for the handset if I recall??? I'd have...

Saw this on the Prism2 facebook group -- didn't see it mentioned on here. This is a direct copy/paste from facebook. AST REBREATHER SENSOR ISSUE As a number of divers are aware, AST has had issues with some of their sensors not reaching higher PPO2s and reacting slowly resulting in them being...

I actually own an O.M.G. / Castoro C96. Jale - you mention you have the same unit? I may need to order parts for mine. I thought the design looked cool so set an eBay alert on it. Years passed and it triggered. One finally showed up. Turned out the prior owner used it to escape the country of...

Was it common for the diver to run high ppO2 like that on every dive? Could have been a mishap or equipment issue?

Internet Archive doesn't require subscriptions or anything. Interesting. Yea I was looking again (I researched this stuff years ago) at various ways to capture the content without harming the magazines as someone might let me borrow a years worth. Flatbed scanning (which is what I have now)...

A. The Internet Archive is a library. B. I'm into preservation regardless of copyright

It doesn't have to be the complete collection end to end. Who cares. Right now it seems there is zilch out there. In general it is my guess there just isn't nearly the interest in archiving SCUBA stuff as there is in the vintage computer stuff and vintage radio and audio stuff. In the vintage...

I visited the Diving History Museum with a buddy a few weeks ago. He was commenting on their periodical collection, and I suggested to him that much of it is likely scanned an online via the Internet Archive or other resources. I checked around to show him, and to my surprise none of it is...

CRAP! I thought I finally had one on him, you are right. I didn't scroll down far enough (I did check but just saw the NTSB thread and others.) Mod - you can delete this thread.

A woman died while scuba diving in a lake at Montana's Glacier National Park - CNN "(CNN)An 18-year-old woman died in a scuba diving accident at Montana's Glacier National Park on Sunday." Also from the article: "Another diver, a 22-year-old man, experienced shortness of breath and was taken...

tbone1004 - Awesome info! So that means anything created to replace the HUD needs to be able to pass message back to the OBOE to trigger calibration. Much thanks for the info!

I have a similar Rigol DSO as well, with the protocol decoder unlocks. A smart friend said the decoders don't work very well. I ended up ordering a DSLogic Basic, which can use the DSView software or the Sigrok tools. Friends also pointed me to the Travis Goodspeed CANBus tools, but from quick...

CanBUS tools on the way. Will report what I find once they arrive and I get a chance to poke at it.

Oh interesting! I wish that diagram was in the Prism2 manual. The people I asked didn't know how things were laid out inside (System architecture) so I ended up taking the unit apart to see. I asked if the protocol was open at the DC Dive Show and was told no. I doubt they want work-a-like...
