[lug] OT: android elevation app accuracy

[Bear Giles]

Actually I just remembered a second approach. If you can run a hose between
two buckets of water you can use it as a level. You'll need to make sure
that the hose is completely full so the water can freely flow between the
buckets but other than that it's a matter of putting the buckets on each
corner of the building and figuring out a way to measure the height of the
water to what you're trying to check.
