I've been building diy housings for a while now and have just seen the threads on this board so I thought I'd let you know that recently I had one tested to see how far it would go before failing - it got to 146 metres. Which I thought was pretty good. Full details, pictures and plans, including how to make controls work though the wall of the housing are here.

I'm working on a design to go below 200 metres now.
