Document your pypilot installation

As a new user it has taken me quite a while to decipher the posts and decide how to set it up.

Here is a link to my installation blog: https://svkatielee.blogspot.com/2019/07/...rking.html

Post your's as comments/replies on this thread.

Good idea; here's a compilation of the making of my pypilot: https://youtu.be/hoFl5Uv_Rn4 (edited as previous link was invalid)

No blog, but some bullets:
  • Converted Raymarine ST2000+ into a PyPilot, putting TinyPilot on a RaspBerry PiZero with wifi and Arduino motor driver in the original casing.
  • Latest TinyPilot image downloaded onto a PiZero, and adjusted to be a client to the OpenPlotter access point (see elsewhere on this forum).
  • Works also stand-alone, as the LCD interface was replaced with user interface that emulates original keystrokes of raymarine keyboard (see github).
  • Motor driver H-bridge made with schematics and FET's reused from the old raymarine.
  • OpenPlotter runs on a Raspberry Pi 3B+, is fed through a RS232-to-USB cable from Emtrak EM-100 AIS/GPS device. Charts are OSENC charts.
The idea behind this is to have a pypilot that can be interchanged with an original raymarine, so it can be commissioned gradually and there's always the original one as fallback option. Hardware can be swapped, and also software allows track steering from OpenCPN in both old and new.

Today was the first trial, and there are some follow-up items from it:
  • find out more about compass calibration
  • find out more about behaviour of manual rudder adjustment
  • better power supply for arduino (now fed straight from battery Confused)) 
  • more decoupling capacitors everywhere.
Cheers,

EDIT MAY-2020: after a few iterations, finally replaced motor driver with a Pololu #2991 
Also installed end-of-tavel switches.
