How do I waterproof?
Admin:
hmmmm how do you plan to have the sonar sounds pass through the resin sphere and not bounce back?
in about a week or two from now im going to run tests on the Sharp IR ( http://www.societyofrobots.com/sensors_sharpirrange.shtml ) and see how well it works underwater. ill post how well it worked by the end of the month.

Thanks, I think that I can use the sonar with the resin as long as the receiver membrane is physically connected to it...
Btw, this sucker's going in murky water, so the IR's a no-go :-[

wow , a really enlightning thread here !

Oh I forgot to post it . . . I was able to use a Sharp IR passing through glass and water of a fish tank to measure the distance of an object moving inside. It worked fairly well at a distance of 2 feet. Just make sure the glass is really clean.

Here is some interesting links (in Japansese, so if you can't understand, use some translator like Babelfish)
