Pipe Insulation and Camera Issues

Post by NERDS » Thu May 07, 2015 3:15 pm

Hi,

Our team is using pipe insulation for our tether buoyancy and we were wondering if the foam compresses at 12ft of pressure where the foam would become dead weight. Our second question is our team has an issue with our camera's for some reason they are flickering and turning grey. It is kinda weird since they did work before but we don't know if one of the negatives or positive leads is loose. Thanks.

Soft foam will definitely shrink down quite a bit at 12 feet of depth. Generally it provides much less flotation at that depth.

Without a detailed examination of your camera, I can't really diagnose the problem. Here are some common issues with cameras that might cause this.

A bad connection. If you extended your camera wire from short to 10+ meters needed for your tether length, there could be a bad solder joint, or leaky seal in the line.

If this only happens when your motors are running, it could be interference from the motors. In a tether, your motor power wires are often right next to your camera wires. This can cause problems if you don't have a proper filter. The MATE website has a PDF PPT about building a camera filter.

Make sure your battery is charged. The camera is usually the first thing to go when your battery is getting low.

Hope this advice helps a bit. You might want to post this in the team chat section to get additional ideas (more people may answer there).

Good luck.
