ROV progress

[jconduto]

Hi
Can you show me how you connect the umbilical to your ROV?

[bikerbones1968]

Do you mean how it is connected physically or via a wiring diagram?

[jconduto]

Phisycally. Have you used a junction box or the wires go directly to the hull?

[bikerbones1968]

Wire go physically through the hull the same as the lighting wires and the wires to the motors. everything is potted inside and out

Hey biker, I really like the control setup! I think I want to do this with my FlySky-TH9X radio. (I have the older model that can do 2.4g or 72mhz) Could you please do a video or an in depth written article on the radio setup, including the proper mixes and such? Also, do you have a pic of the receiver all connected up? Can you show how you powered it? Did you splice a pair from the cat5 cable to the DSC cable and then used a servo lead to plug into the receiver?

Thanks!

Fireslayer26, I have posted the setup and mixes on here somewhere including some wiring diagrams. If you search the forums for the words "JR Radio" you should find it. It doesn't matter if you use a 72Mhz or a 2.4Ghz radio as long as you use the PPM output pin from the radio. The 9X does this for sure from wither the "JR" mono jack or the Futaba multi pin jack on the back of the radio. The easiest way is to remove the RF module and use the pins inside the bay. See the pinout configuration in the pic below. You only need pins 1 and 4 . I powered the RX onboard via a servo lead feeding power from a BEC's off an ESC. If you get hung up PM me.

I just bought this cable: http://www.ebay.com/itm/360679346694?ss ... 1423.l2649

And an R700 receiver. I believe the cable has a female servo connector on the end of it with 2 connections in it. A ground and PPM signal wire if I'm not mistaken. I'm guessing I would just have to connect a twisted pair from a cat5 cable and run it down to the ROV and connect it to the battery socket on the receiver according to your diagram on page 1? Also, what kind of servo relay do you use for your lights? Have a link to the lights you used?

Thanks!

I just read the description for the cable you bought. Not sure if it the correct one or if it will even work. It says in the ad that it connects in the charging jack which is not correct. When you get that cable take a good pic of it and post it here for me to figure out what the heck it is.

Just remove the module, and connect to the two pins as shown in the picture. You can just solder to the pins and cover with heat shrink. Or if you need to use the radio for flying or other purposes rip apart an old computer tower and salvage a 4 or five wire socket and use that. You only need two wires 1 (PPM) and 4 (Ground). Ignore everything else. Those two wires connect to the signal pin and ground pin on the receiver "BAT" channel. Power the receiver with only one 5V BEC off an ESC. Remove the center RED wire from all other ESC's they are not needed. Real simple to do and your off to the races.

Somebody needs to come over here and slap me so I stop trying to find the hardest way of doing things. Nice looking thruster Bones, have you done any testing to see what they put out?? How about a video of them kicking up some waves??
It still kinda freaks me out though, running an electrical motor exposed underwater, I work in a water plant and it only takes a little bit of water to distroy our motors. But then agin they are a totally different beast.....

Thats the beautiful thing about these brushless motors and DC voltage. Water is not an issue. They are happy to run submerged without seals or in enclosures. Just wash them with fresh water, blow them dry with compressed air, apply a little moisture displacer and non conductive lubricant and your good to go.

What do you suggest for a moisture displacer and non conductive lubricant?

Thanks!
