I guess this belongs here for now, or in the KISS forum, or in new products later!

As I understand it, the HUD is hardwired to the Kidney and there are batteries in the Kidney for the HUD.
Battery for the DOT is in that unit, so the only common electronics are the Cells. Either the HUD or DOT can fail without affecting the other.

The Tachyon is extra, with it's own battery still monitoring the same cells.

So redundancy is similar with 3 independan monitoring devices, albeit commoned at the cells.

If the inputs are buffered a complete flood and SC of the DOT or Tachyon should affect the readings in a miniscule fashion.

The Kidney is potted so should be resistant to flooding, not sure how this affect replacement of the HUD or DOT leads if you screw them.
This is what started me looking around

Bailout calcs?

That's the DiveDrive you're describing.
The MicroDOT is the handset only, with pO2 monitor and dive timer/depth display. Single display, single cable, single battery, and it replaces the tripple redundant Jetsam display. That, in my opinion is a step backwards. No way I would dive any rebreather without redundant (as in separate and independent) displays.Yes, calibration is superconvinient and the depth and time readout are nice to have, but there is zero redundancy.

The Tachyon is optional, and only redundant if it is additional rather than a replacement handset. If it can be plugged it, so should the HUD. LEDs don't use much power, yet I would prefer a separate battery for said redundancy.

Ideally there would be a replacement kidney or pod with space for a small battery (HUD) and three connectors:
MicroDOT handset and HUD (both standard) and Tachyon (optional).
Basically a DiveDrive without the solenoid and associated wires and cables.
Call it a MacroDOT.

Hi Stefan,
Yes, it is, sorry, I did not read your post properly to realise that you were distinquishing between the two.

Yes, the flexibility of that would be nice, perhaps if the Microdot went down, at least you could dive the HUD/Tachyon while it was being repaired/exchanged.
My only reservation would be the addition of connectors as failure points. I don't think a leaky connector would cause a flood of either end, but you'd lose a display (HUD/MicroDOT/Tachyon) until you sorted the problem.

Ahh yes

Actually I agree that failure points should be kept to a minimum.
No sane reason not to hardwire the MicroDOT and HUDs.
If for some reason either is damaged and needs repair use the stock bits.

A flood due to a leaky connector is probably less of a concern than shorting
the system.
You don't want to loose your alternate display due to bad data.

So we're back to the Divedrive then ? Errr, without the parachute.
My plan was to hang onto the original bits and not sell them for the very reason that you mention.

Sorry, yes that's what I meant, saltwater in the connector shorting the pins so that the sensed/dispalyed O2 was incorrect.
