Re: Making a thruster from a DT-750

I'm sorry that I have to ask but how would i build this "oil filled" ? Are there any designs on this? Tips ideas? I'm no "inventer" nor engineer myself. :)

Making a thruster from a DT-750

Hello. How long will a DT-750 last underwater in salt water? Wouldent it short out and burn? Is this something you reccomand me to use? Will "potting" the copper windings be a smart move to make it work perfect under water? Or anyone got a smart idea to make my rov operate in salt water do...

Re: Rov from Norway

Hello Fellow norwegian ROV'er :)

Wondered about your thrusters, what depth are you thinking to gain with them? And will they work in both salt and fresh water? I'm looking for a thruster for 50m depth atleast. Tips and ideas, please tell me :)

ArduROV

This ROV will be up by the summer (the goal). I'll be building this ROV based on a Arduino "brain" and bilge pumps. Hoping to reach about 50 meters.. (read hoping..) dont know what to do to the thrusters since i dont think i'll get 50 meters with the bilge pumps. Any great ideas for thrust...

Re: Need WTC Ideas!

"Dang" .. I cant find any idea on how to make an watertight compartment! Thats mostly all i need. I need a "big" compartment with space enough. The pvc (scheldue 60 80 ) it not to be found in norway. And i really want it watertight engouh to 50 meters. Anyone got a "simple&q...

ArduROV

Hello! I'm creating my first ROV now. I've started buying the wet-frame parts. Electronics and the WTC (WaterTightCompartment). My plan is a 40x40cm squared rov using 32mm tubes for wet frame. http://link.jepb.no/OsRh/Cloud2go%2010.%20mai%202013%2017%3A33.jpg As you can see i have 6 thrusters and a ...

Re: Need WTC Ideas!

http://www.skylighter.com/6-inch-fiberglass-mortar-tube.htm What about theese, will it be stronger than PVC? And is it possible to fill the hull with pressure before diving to equalize the pressure a little? 10 bar inside = 0 bar at 10 meter down, then at 40 its only 30 bar pressuring.. Adding 20 ba...

Re: Need WTC Ideas!

Just a quick question before i leave (I'll read rest of the post tomorrow just saw the images now) but do i really need that much cooling for the mosfets at 3.5-4 amp / 12v ?

Re: Need WTC Ideas!

Nice, how deep does it go "watertight"? Tested any limitations? I'm probably gonna do the same as you, but using mosfet, diode and resistor for each thruster instead of relays. Using mosfet's i found in my hobbyroom which is rated for up to 60volt and 30A. Should be enough for each thruste...

Re: Need WTC Ideas!

Ahlsell is my company's wholesaler so i might hear from them. Will check it out. But what do i need to make my WTC? What did you guys do from "norwegian" supplies? I mean, i need to be able to open it easily and have a tether cable? 50bar? What do i really need? Going to have a camera, 2x ...
