Well, its been 8 years now. Still nothing built :cry: But I haven't lost interest.... Hey David! this is such a cool project! I would encourage to do it... if you need any help just ask. If you surf the web you can find a lot of tank bases in which you can build your design around. I would suggest ...

You went a little overboard encasing the ESC in epoxy...i just meant, thin it with denatured alcohol so it has the consistency of water, and brush it on...thin...lol. And those wires going through the penetrators?? I hope you stripped the insulation off of the part of the wire that goes through the...

Hre is the ESC waterproofed with epoxy resin... IMG_4195.JPG IMG_4194.JPG Heres the penetrator with all the wires used to control the servos and the motor. The penetrator was 3D printed for testing purposes. The penetrator was closed using wax and hot glue. IMG_4204.JPG IMG_4202.JPG IMG_4201.JPG IMG...

Heres the stern 3D printed. Tomorrow I will use resin to waterproof the esc. The bottom file is a little gif.

I looked at your servo. From the description it has rubber seals to keep the screws from leaking, which means it is water-resistant, not really waterproof. The reason water tries to get into our servos is because there is an empty void to fill. Fill that void with mineral oil and the water will no ...

Hi guys, I am still on the project. I was away from home for a while so I had to pause the project. During this time I received various I2C components that I will use for the ROV (voltage and current sensor, pressure sensor, temperature sensor, luminosity sensor, humidity sensor...). This is the vol...

I strip the wires, then cut a strip from an ice-cream container lid, with little notches to hold the wires separate. Then epoxy all over and ...waterproof. If you are talking about inline bullet connectors, immerse them in a tub filled with mineral oil, plug them together submerged. Mineral oil is ...

Do anyone of you guys know the electrolysis/corrosion effect I could have in ESC wires if not completely sealed ? The ESC of course will be sealed. But the copper wires maybe will have some leaks since I will solder them and only put some tape. Did you had corrosion or electrolysis experiences with ...

Here are some pics of my first ROV that I named ROVTNIK . The ROV is based from one of the ROVs showed in the book: Build Your Own Underwater Robot and other wet projects by Harry Bohm and Vickie Jensen . To make it I used brushed motors sealed with wax. The control box/wiring was also sealed with w...
