Yes, the stress test was a nice touch, although not quite planned for :-)
Software, good question, I used the version that came preloaded in the 2.6 kit which ever that is they ship it with. Have not looked into it yet. Received the kit early February, so presumably it is the latest version from github: https://github.com/OpenROV/openrov-image/blob/master/CHANGELOG.md
See that the latest image is dated 26/28-11-2013, so I guess this is the one I use. Or is there a way to see the revision no in the cockpit? Have not really looked.
Hysol 90: The European Equivalent apparently is Loctite 9489, but that also appears to be a Holy Grail amongst the epoxy alchemists, at least not easy to come by in Norway. I'm sure there are other stuff that will do the trick, but to be the first one to try it is a leap of faith.
Another issue: IMU. As described earlier I connected the IMU/Depth module as per procedure, updated the config file in Putt and uploaded it into the Arduino. After that it worked great once I changed the position of the module, except for the compass data, which was far off by approx. 80 degrees, but was updating. The OROV cockpit gave me associations to flying a F-16 for a moment as I watched the screen flicker with artificial horizons and banking indications as I performed break dance with my Rover.
Next day as I wandered into my little workshop with a cup of coffe and thinking happy thoughts, I cranked up the Rover, suddenly all IMU data was dead as a dudu. All that remains is the depth and temperature data, which still ticks along. I had not done anything to it, it worked like a charm the day before, but now suddenly the IMU part is dead, the cockpit is showing 0 for value for all pitch, yaw, roll and whatever. I tried to upload the Arduino again, but the same disappointing result. If it had been a wiring problem, I would suspect the depth values to be dead as well since it is communicating on a I2C bus. That leaves me with 2 alternatives as far as I can see, either the IMU circuitry on the board has gone to Silicon heaven, or there is something dodgy in the software department. If anyone else has experienced something similar, or have some cunning ideas, feel free to share them here.
