I am using V-Ring seals from Mcmaster Carr PN9572k31. Have only tested to 8ft so far. The smallest diameter is 1/4". I used several "telescopic" pieces of brass tubing to increase the size of the shaft. I will attach pictures if I can get them resized small enough to add.

I work for a nonprofit also. I use the Diamond VC500 One Touch video capture system which includes the video cable that attaches via USB to a laptop and software. It works very well and is easy to use. Cost less than $40 I am very pleased. I bought mine from Newegg but I'm sure there are other sourc...

I make my own. I use a 1/8" id piece of brass tubing then put a piece of 3/16" id brass tubing over it for strenght. Drill a hole through the tubing on both ends a use model airplane wheel collars which has setscrews. If your prop is threaded you can get a die and thread a solid piece of 1...

I wonder if you could modify a six bladed ducted fan prop. The 6 blade props have opposing blades. I'm not sure the pitch of the blades but it might be a solution.

I ordered an EDF assembly this week to do a little testing. It is only a 2.75" fan but for $8.75 from Hobby King with shipping I couldn't resist. I want to find out how much thrust the fan produces and the current draw. I suspect current draw will be OK since the pitch of the fan prop is less t...

Great work. I'm starting a new project and want to use a dome. I originally thought about schedule 40 but then I would need to add a lot of weight for buoyancy so using heavier sch. 80 seems to be a better choice. Where did you get the schedule 80 PVC? On the front end where the dome attaches what i...

Looks good. How difficult was it to get the Arduino to communicate with the Rasberry Pi? I have thought about a GUI front end for various monitors like depth, temperature, heading etc.... but have no experience with the Rasberry.

CAT5 is cheap and a lot of IT departments have old CAT5 they have pulled laying around and will give it away for free. I got 100ft of CAT5 from my it department.

You could make the ROV square and mount the claw to something like a jackscrew between two rails so the claw can be raised or lowered depending on what you need. The rails would keep the claw from twisting as the jackscrew turns.
