Homebuilt ROVs Forum

Big Update! I have the control system working finally and did a tank test. Details are on our local electronics group webpage: http://kitsapcreate.org/wp/?page_id=313 I have some adjustments to make to the control system so it matches the scheme I want. I lost one of my batteries due to a bad cell b...

There are a few places to buy inexpensive high power LED's one being DX.com. I have a pair of 5W Cree LEDs on my ROV with diffusor lenses that give a very nice spread with almost no shadows or artifacts. They are mounted in 1" aluminum tubing and potted with the drivers. The pair draws 1A at 12...

Welcome! Where are you exactly? I am in Bremerton and have used my ROV in the areas of Illahee Park up to Agate Pass Bridge so far. Once I get my new tether done and the ROV running again I hope to hit the deeper water and do some wreck diving. There are a few of us in Kitsap working on ROVs. I am a...

Just an update. Turns out I was having multiple issues (comms with PS2 controller, 485s etc.) I had help last weekend and my programmer/ electronics expert friend figured out the issues and we are closer to having it work. Likely we will create another Arduino based board with 485 comms similar in c...

That last one should work.

I am in Bremerton so not too far away. I am hoping to use my old laptop screen at some point for a built in monitor in my pelican case.

I am using the same sensor with 500PSI rating. I think if it is stainless it should be ok in seawater. I plan to rinse it out after each run.

I would recommend not using a gasket, I had major issues with a gasket leaking over using O-rings which are much better at sealing under pressure. You don't want a lot of surface area as it is harder to compress it enough to get a good seal. Take a look at professionally designed housings, they use ...

Welcome! I am just across the water near Bremerton. Looks like you have some neat projects!

I am using the MAX485 modules like this:

I still am working on it but I suspect there might be some differences in the programs. I am hoping to do only one pair on the cat5 for comms.

Fill the connector with non-conductive grease and that should keep the water out as long as the grease can't move somewhere else.
