Anyway I can help. Keep in mind with the compass don't solder anywhere near it or you'll destroy it. I did that to the first one had to order another one. I used a surface mount IC and cut it to build a square then made a circuit on a breakout board from radio shack then plug the compass into that. ...

Sorry guys I been real busy lately. The Arduino's use TTL for communication which is rs232, but you can only get like 15' distance on communication. (I dont wanna rely on a laptop out on the water so Im just using Arduino's for all the work). If that makes sense. So the rs485 chips convert that sign...

Been a while since I've posted anything still working on the new design. Its coming together but slowly. I currently have bits and pieces of arduino code working and I'm putting the code together. I ordered 4 new rs485 surface mount chips for converting Arduino signal to rs485 and back to rs232. The...

Man i love the plans you have laid out, our set up's are so similar course you have much more going in i think. I got my driver for the dive and surface motor, the 2 motor carriers work perfectly i get a smooth ramping of the motors forward and reverse. I have had to set a dead band range at the cen...

http://www.homebuiltrovs.com/rovforum/viewtopic.php?f=31&t=432 Here is the driveability of those ducted fans with the relay set up. I get the same speed forward or reverse. I haven't looked into the props for a couple of reasons one cause i don't wanna buy a bunch to find the right ones to use a...

These little fans are awsome and move the ROV really good but. They are brushed motors not brushless and they need to be turned on at the same time and at the same amount to drive it straight. One reason for analogue speed control with the ps2 controller. Brushed esc's are expensive $80 to $100 a pi...

The esc is treated like a servo using the servo library. But I'm scraping the esc. its just to hard to get mapped correctly. I have been struggling with it since the begining and just when i get it running the way it should something changes and im back to tuning it. I ordered one of these http://ww...

Dude that's AWSOME!!! How does the hull hold up under pressure?

I got a playstation 2 controller running and esc and controlling a motor with variable speed through an Arduino Mega. Hey Deakel, Thanks for the comment! Follow up question for you, did you find that you had to preset your PWM output to 145 (ish) in order for the ESC to initiate properly? Probably ...

Nice work man I have the same triumphant feeling as you have. I got a playstation 2 controller running and esc and controlling a motor with variable speed through an Arduino Mega.
Its a great feeling Im with ya man.
