Is there a way to check what the current firmware / software is on the supplied mother board??
A quick bit of advice!!
When potting the sensor.. make sure you keep pressing the PCB into the resin.. one end of one lifted!!
So its not dead straight!!
I'd also hang fire on super gluing it until you have checked the live telemetry readings to check it mounted level!!
Also there really should be a note earlier in the construction asking you to add the PCB whilst looming in the earlier stages.. sales you having to reloom it and take it all apart again!!
Other than that.. just awesome!!
This upgrade is a must for anyone buying this cool bit of kit!! :)
Hi again all..
1. Cut the orange black wires at the loom end (allowing sufficient wire lengths to resolder and insulate later.
2. Shake the tube up and down like a teenager discovering the internet for the first time!
3. Eventually you will get the right wrist action and hopefully release one of the batteries (Like trying to shake tomato sauce from a newly opened bottle).
4. Carefully poke a thin coat hanger with a small L shape bent on the end of it (taking care not to score the tube excessively) passed the remaining battery and hook it out carefully (avoiding damaging the battery terminal.)
5. Resolder an additional length of wire to existing wire (don't use any insulation sleeving).
6. Using a long screwdriver, Poke the offending heat shrunk joint all the way down to the spring terminals, coiling it out of the way of the terminals.
7. Cut the new extended wire to the correct length and resolder terminals etc (Test for ease of battery fit)
Hope this helps!! :)
Like Ryan, my orange wire is way to short.
But there really isn't enough tolerance on the length of the wire.
I also added some spare wire to extend it.. soldering and heat shrinking the joint.
Unfortunately the joint is fractionally to thick to allow the batteries to fit freely.. you have to force them.. then guess what.. you can't get them out.. and you can't get the correct tension on the negative spring loaded terminal.
Also by this point you have cemented this end cap shut.. so you can't get access from the other end either to rectify the issue.
Why not just have rubber bungs fitted on this end and allow them to be removable.. or at least delay the cementing of the joint until you have tested for the fit of the batteries.
I'm now racking my brains about how to extract the batteries and how I am going to be able to modify the swollen solder joint.
Like Ryan said.. if it was closed to the terminal it would be fine I think..
Any Ideas?? :)
Hi there fellow Submariners!
Just a quick question about the potting stage using free flow epoxy resin.
Ive got just standard waterproof epoxy.. its a 2 plunger system but has to be premixed and then pasted with a stick rather than being injected via a plunger.
Is is acceptable to paste in this epoxy from both sides of the orifice??
Also wouldn't silicone sealant suffice (this is readily available in a trigger gun powered cartridge??)
This should easily flow around wires etc..
Also I am considering adding an additional set of sensors to measure temperature and water salinity etc.. should I consider adding additional wires through the orifice prior to potting it??
Appreciate any advice anyone may have!!
Many thanks and cheers!!
