KISS cell splitter - pics?

[trimmatters]

Hey team

KISS Sidekick

Picked up a cell splitter board and whilst I had some thoughts on how it might all fit together when ordering, they have not panned out.

Anyone got a pic of how they’ve fixed the board into the head? How does the bracket get involved?

Anyone know how it’s done?

I am absolutely certain I’ll be kicking myself once someone posts a pic, but it’s always when you know the answer.

That’s a splitter board for a Sidewinder, not a Sidekick. Real pity if that involved postage from the states.

You’ll need either Molex Splitter Cables (which triple the number of horrid exposed Molex connectors you’ll use) or to find one of the small batch boards and solder the terminals end to it yourself. Note, this may also allow you to switch to vastly superior SMB cells (a la Fathom, JJ).

Hmm

I had that conversation with the team at Narked at 90, and the item is listed as "Kiss rebreather cell splitter circuit board-FITS SPIRIT SERIES AND SIDEKICK"

In an email I asked about the molex splitter cables and their Molex head unit, but was pointed back to the need for isolation via the board.

I've also reached out to the team at Narked at 90.

Thankfully shipping from UK is slightly more gentle than the US

Yeah curious what they suggest. Ideally you end up with something this sized:

I think Mick still has his SK but he’s over in Sydney. If you run out of other options and aren’t in touch w the rest of the Aus SK community let me know.

 

[trimmatters]

Right, to close this one out.

Yup, that was a Sidewinder board. Trouble is, KISS listed that part for both the winder and the kick as two separate items - as relayed by N@90

Have ended up with the molex splitters, and yeah, they create a mess but hey, and some custom cables with isolation built in.


I've got a big trip out Nullarbor kicking off Friday so I'll post some photos when I do a breakdown at some stage for reference.

Last challenge in the locating of the LED thingo itself. I have the Golem SM DSV and the included bit doesn't play nicely

I've got a lead on some 3d printable ones that might fit the bill, but if anyone has something, please sing out.

Otherwise it is duct tape and zip ties again well, at least to get an idea of what I need. This trip is in ~10m depth, next one is where its going to be needed.

Hi
I do also have a SK but I don't see the point of this "splitting-business".
Indeed, is it not better to have a single monitor with a single nice cabling than two monitors with these "duck taped-isolated-splitters"? Real question.

 

[trimmatters]

ok, I like it.

@jale, the tape was to assist with locating the LED readout lights in the right spot, nothing to do with the splitting, nor isolating. The holder for the LED readout which attaches to the Golmen SM DSV hose adaptors was the wrong size (too wide, designed for the non-SM version) and I did not have time to organise a more suitable one prior to the trip.

As for why, why redundant anything? For the 10m (ave) depth dives, not really an issue to have only one O2 readout. For some of the deeper caves, its a very nice to have.

The logistics of the diving out on the Nullarbor Plains in Australia can be quite challenging and I've already damaged a couple of Fischer cables. Sure, can (and do) carry a spare cable, but there's also dry/air chambers a long way in that offer plenty of opportunity for damage during the dives.

I do need a proper holder for the LED readout and I think I'll go some velcro straps to hold the cable to the loop hose itself.

Because the industry standard in CCRs for decades has been two (or more) independent monitors. Commonly one wrist mount and a HUD. Sometimes two wrist mounts, sometimes two wrist and a HUD. This level of redundancy has been the default for decades.

At least a couple people have died with the "one is enough" monitoring that somehow seems unique to Kiss products in just the past couple years. Would they have avoided hypoxia and survived with a HUD blinking in their peripheral vision? That isn't any answerable question.

 

[jale]

Thanks for your answers.
My questions was to restart this talk about this monitor redundancy which for me is a bit a false sign of security.
Indeed unfortunately some accidents happened with single-monitor-units and as @rjack321 said there isn't "any answerable question". But accidents happened also with redundant monitoring.
Rule number one is to know your ppo2 and to have one or two or three monitors should not change anything to the frequency you check that.
You should not wait for a flashing hud to be aware of a need to inject oxy or dil.
That why, in my mind, a single direct connection from cells to monitor is better than a splitting system.
Furthermore, all monitors are linking to these cells and I think that nowadays we don't do enough flushes to validate the reading; we just wait for a disagreement to act.
Personally, I started with home-made units with two cells and a single monitor in a tube. To validate the reading, flushes were done regularly. Yes more dil is needed then what?
I just got the feeling that all these extra monitoring based on three (or more) single cells placed in the same place are just making divers more and more passive in their monitoring and that should not be the case.

I'm actively working to make sure that having a heads up display on an analog rebreather is going to be easier for those with access to secondhand parts market.

That is an analog Petrel 3, and that is a dive can SW HUD. With tremendous effort by others my only goal using their effort is to facilitate HUD usage. This is on my analog only head. Prototype board by a brilliant individual running dive can.

Ironically the board grant posted above is exactly what I'm getting my signal from (One of the outputs of a SMB splitter board)
