"Hi Steven,
No I have not, but it would be nice as I believe the Network2000 is essentially CAN.

"John, I love the boat and it looks super sleek in the water!
I have a question for you. Were you ever able to adapt your sonar onto your pixhawk setup? I am doing the same thing, but have a pixhawk for guidance, then an arduino board for my airmar…"

"HI John, great project.
Your boat might be veering to starboard because of pontoon or hull alignment.
Have you tried higher STEER2SVR values yet? It seems that the weaving is an over correction. I had the same with my skid steer Rover. I'm…"

Mapping Boat 'Fly Away' during Mission - WHY?
Boat: 3-meter trimaranMotor: 2.5hp Suzuki 4 strokeController: PixHawkMapping Speed 14-19kph (4-5m/s)Fly Away - a. During the North / South routes everything seems ok, except the wobbly courseb. When the East / West routes start, it immediately fails to do the short route from #52 to #54, but rather does a full west run to nowhere, then returns to #54, but then skips #56 and #58 and goes straight to #60, BUT NOW THE ROUTE IS IN THE WRONG DIRECTION!c. Then rather than gpoing to #62, it heads off…See More
Servo PWM to H-Bridge (High Current)
Hi all, as some of you might remember I was having a problem with my survey boat zig zagging terribly while carrying out a mission. At first I thought it was a Mission Planner parameter setting, but it turned out to be the little L298N H-Bridge failing due to excessive heat. This was caused by me upgrading the outboard motor to a Suzuki 2.5hp four stroke which turns out to have a LOT more drag on the pivot (steering) column. This drag put extra stress on the little 2A H-Bridge causing it to…See More
"Hi Ben,
For throttle, any little servo works fine, just remove the idle spring.
For steering a car's wiper motor works fine, just find one with little to no play in the arm.

John"

Hello Mr John.
I was following your Pixhawk Boat Project. That is very amazing and technically great.
I am curious about one thing and hopefully you can help me out on this.
you mentioned that "Steering servo is via a vehicle wiper motor for torque using an old servo motor for potentiometer and output to a H-Bridge L298N"
I am trying to control a DC wiper motor same H-Bridge controller with arduino, but its not precise.
Can you elaborate your setup for my help ?
details of your setup and pictures or wiring will help a lot. and if you modified code for this, that will be great to share.
Looking forward.

Hi Tipu,
I am having the same problem with erratic steering and am trying to sort it out currently.
Regards
John
