Hello all,
We are 4 friends on a 40ft sailing boat, we took a gap year to sail
Currently we are stuck in the Canarias, because of our B&G autopilot which is 20 yo and has decided to retire...
So we are looking into pypilot, nothing final yet but we have a general layout in head and I would like some feedback and general warnings before hands!
What do we have?
- 1 developer + 2 mechanical engineers so limited electronics experience...
- Old installation http://www.dahlberg-sa.com/wp-content/up...42-ing.pdf
-- hydraulic ram 12V with a reversible electric pump (20-25A and a clutch (solenoid - 2A)
-- B&G Compass
-- Rudder angle reference
- New equipment
-- Raspberry Pi3
-- MPU 9250/6500
Well this is our first Raspberry Pi project, so we will take it slow, at the moment we are getting stared with the raspberry. I imagine next step is to download openplotter and py pilot and have them working on the raspberry.
Then comes the issue of the controller.
Our ram uses typically around 5-7A, I dont know for the bursts? Direction is by reversed polarity, the solenoid clutch is to allows to move the rudder when the pilot is off.
So I am guessing that this current is too hig for Sean's controller? Can we adapt the scheme you posted above? Or are we better off looking for an available one?
thanks in advance for any advice and comments! As I said we are complete beginners, so do not hesitate if you feel we are going the wrong way!
