content: Dave, I want to be the first to say, I'm impressed! Even after the 30m drop, it seemed from what you showed us that it would be enough to replace the LCD and inductor again, and it would be as good as new (assuming that the board didn't crack and lose connection somewhere...). That's quality build!Thanks!On a side note I wanted to ask if, in your opinion, some kind of rubber or foam gasket around the LCD would make it more impact resistant or are there just certain limits to the force that an LCD screen will handle?

content: Yeah, I haven't actually tried to fix it again after the 30m drop, but I don't see any major problem, I would be surprised if a new LCD and inductor didn't fix it again.An extra rubber internal surround on the LCD housing assembly would make it more compliant in both on-axis and on axis directions of the LCD, and hence provide increased shock absorption. But there will always be limits of course.I think they could make it even more rugged if they wanted to!But geeze, it's impressive what they can do with impact resistant plastics and a standard glass LCD!Dave.

content: Man that was like an Electronics Engineering version of Top Gear. That meter is all but bullet proof... or is it.

content: Dave, great video! I would have liked to have seen a crappy meter dropped from the 30m mark as a comparison. : )- Patrick

content: Dave, this made me laugh so hard!I had an idea once to make a blog called "ExtremeElectronics" where I would solder, calculate or some other electronics-related task while rock climbing or water-skiing. This is pretty much what I've been wanting to do for a long time!I was wondering, do you use a dry-rope for those water rappels or just man up and carry the extra weight on the way back home?

content: Quote from: rossmoffett on March 07, 2010, 10:51:57 pmDry treatment is a bit of a myth, it doesn't help much for canyoning, the ropes still absorb the water. And the dry treatment wears off pretty quick in this environment and pollutes the creek. So I just man-up and carry the extra weight on the way out, sometimes two packs if someone else can't hack carrying theirs. I had over 100m of rope for this 30m abseil.Dave.
