Ritchie Navigation not helpful
Hello I know some of you use magnetic compasses with a camera looking at it and send live to your recordings or video monitor. Well I tried to get help from Ritchie Navigation who make great products. Their staff that I dealt with are very unhelpful and I would get other brands. I would go with Plat...

Re: Easy way to make a thruster exit shaft.
I have three Neptunes and never had a leak and I had one down real deep. The motor bolts to that aluminum bulkhead with stainless steel screws and O,rings around the screws as there are machined recesses for that purpose. on bearing on the end. But with oil insie the enclosures it may work. I never ...

Re: voltage
Here is an ROV using 220v I don't feel so idiotic after all.

Re: Pressure compensation
I am only wanting to do that with the thrusters not the main hull. I could get brushless motors and oil fill the enclosures but oil in brushed motors won't work. but will in a brushless design. I could build my own enclosures with the waterproof seal on my Neptunes. but I don't know I can get them o...

Pressure compensation
I have a question. can you compensate pressure in a thruster with air?? I want to use a bilge pump enclosure. If I can put in a pressure compensator like a syringe with a little neoprene or appropriate hose conected to a barbed fitting on the motor housing and on the end of the syringe. i can get an...

Re: voltage
Yes I know what is in the franklin motors. it is food grade glycol. it is in case of leakage it won't compromise the well. The water/Glycol is only in the rotor section of the motor to lubricate the bearings and the thrust bearing. the field is potted in resin sandwiched between the stainless steel ...

Re: voltage
I am looking at the Hyball and the specs are 110V or 220V and state if running off a genset must be around 7200 watts. I have decided to go high voltage and it will be safe to swim around. I see divers working around ROVs and they are high voltage. I am thinking of using silicone oil or mineral oil ...

Re: That's going to leave a dent in the Wallet
News travels fast. I hope he gets another one. I understand that things are not living. but I have things that i rather not lose. My Prius has 220,000 miles on it and if i lose it I will be very sad. I understand his sentiment. I truly do.

Re: voltage
Has anyone here experimented in NON public places with 220V systems? I know voltage drop would be much less a factor if oyu go 1000 feet or less. I was scolded on the robotrov site for this question.... but someone here must have tried it. as i know the commercial ones use 13,500 and up. I am an ele...
