Darlene, do you have any manual way of dumping O2 into the loop? what are you using? I was thinking of using a Jetsam Kiss valve in parallel with the solenoid w/o the orifice in it. BTW nice bit O kit on your part also, I just used stuff that worked already, you built the elect's from scratch. My hood is off to you

hmmm, need a smiley that shows "my hat is off to you" any takers on coding that???

Ron,

I went with plugs because they are replacable if need be, and because the recepticles are sealed, so that if anything goes south anywhere, then the main electronics canister can't flood.

The other nice aspect of a plug in system is that it's modular to the extent that you can have spares ready to go, or just replace a single damaged item.

As far as manual O2, I run a normal KISS valve in parallel with the solenoid. I can run manually just above setpoint, (so the solenoid doesn't fire) or let the leccies hold the SP.

The kiss valve and the Jaska each have their own 1st stage on the O2 bottle.

[quote=narked at 90;69923]Dave had the concept of the 3 k1d and Dave i have every respect for you, this one made for Ron was modified from it's normal design to fit his needs, but Dave if you ever think this is a money spinner I've only ever made 6 or 7 and am more than happy to put you name on them if you so wish,maybe we start to call it a DS3 after Mr D Sutton
at the end of the day some recognition of an idea makes me feel good
"how about you?" but it isn't going to make you rich but will give you a lot of stress if you want to produce them

kind regards john routley

John,

Yup, just a little recognition would go a long way.... :-). I am VERY happy to not be making up this stuff.... once I prototype, the production is boring....

Topic for another post, but I ought to show one of the new "folding" 3 cell probes with the gas injection port included. This actually does go to Ron's thread though, which is that it's possible (a fait accompli actually) to have a plug-in CCR conversion that one can walk up to ANY rig that has a P Connector installed, plug it in, and dive CCR. The basis is the 3 sensor probe *with gas injection port included* and that connect that to the 02 pneumatics system, KISS type or ECCR as Ron has done.

In any case, fine work from BOTH of you, Ron & John.

Ron, do you find the (smallish) counterlung volume of the Dolphin to be adequate? SCC counterlungs tend to be smallish, as they are run full all the time (CLVmax = totally filled on every exhalation) , while dedicated CCR lungs can be much larger, so that one can run CLVmin (counterlung volume minimim = fully collapsed on inhale), CLVmax (the other extreme, fully filled on exhale), or anyplace in between. Allows depth changes to be met on a routine basis without loop venting on ascent (think 3 meters over the edge of the wreck) and then back to the bottom without needing to waste diluent... I always found the Dolphin loop volume to be a bit small. Comments, since you have more experience with them and I have one on my shelf begging to be converted... :-)

I hope you're not going to claim that one Dave, I've been prototyping one for a while, and know of at least one other guy here in Oz who built one a while back too.

Cheers,
Jason.

Interesting explaination of cross platform logistics in a homebuilt. Good one! Would love to see a complete/assembled unit once your tank brackets come in.

RonMicjan · 30th September 2006, 16:47

Im going to borrow the tank mts off of my sport kiss for the time being, the only thing I am still missing is a P port female that I have ordered from W&S.
I will have it together as a whole unit on monday but wont be able to dive it until the P port comes in. sigh... gonna head up to canada on the 11th, so will wring it out then.

I have found the dolphin CL's to be a bit big on me (maybe I just take small breaths) and I shrink that down with my backplate adaptor, this really helps buoyancy changes and keeps the Cl's to an optimum loop volume.

I think that Tom Rose has a similar device for plug in conversion with an injection port, he showed it to me at dema 2 years ago attached to a tube with 2 displays. He had mounted in it 2 merc switches and tippin it up turned it on, and rotating switched between sensor 1 and 2, pretty slick and no through hulls for switches. Elegant.

Dive Rite Express has the female P ports.

their number: DP-C16 ... $39.95

Delta P Technology VR3 Rebreather Accessories

Should be a bit faster and cheaper shipping for those in the states.

good to know, I usually get them from my local draeger dealer but he has them backordered, I needed some other dolphin parts too...

Hi Dave and every one
Dave i have changed my website to show it was your original idea
and have renamed it from DD3(donkeys dick 3) to DS3 (Dave Sutton 3)with an appropriate mention of you.
by the way Dave i did send you a number of emails about me wanting to produce a few for my self a couple of years back but got no response from you:-(
with the kindest regards john routley

Well... thanks! Honors! Sorry I never replied, was probably out flying for a month.

As for the gas port addition on the probe, *yes* I am claiming it.. all of my probes *from the first one* have the drilled port that carries the wires thru the probe drilled right thru from one end to the other, and the penetrating hole thru the "exposed to the water" end has always been threaded 3/8-24 and counterbored to the standards for a LP regulator port. I either install a blind plug, or a regulator swivel into which I feed gas. If I use a LP tee, I can inject both diluent and 02 thru the same port.... so yeah, I claim credit for that too.... circa 1999. I also claim credit for the folding 3 cell holder, which folds after installation so it does not tend to tent-pole the counterlung. *And* I claim credit for the single sensor probe fitting thru a P-Connector as used by Delta-P, as Kevin Gurr traded me my (2) VR-3's for the design rights... :-)

Ron, still interested in my counterlung volume question.

Best to all,

Dave
