Or has that detail not been worked out yet? ;)Rick L.

To control the buoyancy of the float, a small amount of oil is contained within the float. When the float is submerged, all of the oil is kept entirely within the hull. When it is time to rise to the surface, the oil is pumped into an external rubber bladder that expands. Since the weight of the float does not change but its volume increases when the bladder expands, the float becomes more buoyant and floats to the surface. Similarly, when the float is on the surface and it is time to submerge, the oil is withdrawn from the bladder into the hull of the float and the buoyancy decreases.Last edited by redboat219; 05-07-2009, 11:06 AM.Make it simple, make strong, make it work!Comment

maybe you can utilize something like this;

My idea is to simply change the volume/displacement of the cylinder itself.

Close.
Think two or more telescoping sections of Lexan or other such material.

David I like it.
Would such a system be power hungry - high current draw?

You would not steal a wallet so don't steal people's livelihood.
Think of that before your buy "cheap" pirated goods or download others work protected by copyright. Theft is theft.

This would be so neat in as a 3.5" SD - perhaps for the HMK Permit?
