Yeah, so...


The more I read, the more I'm getting a bit intimidated with the whole control system thing. I have zero problem with the mechanical & electrical build - I'll happy work away at that kind of thing all day, any day. Car-related tinkering is my forte. But the whole software part is well outside my comfort zone.

Early in my life I was into coding / software, but my interests subsequently drifted to mechanical engineering - with "computers" being essential tools but definitely something that specialists dealt with in detail, not me.

So with regards to all things "Pi", I'm rising from a low base. Going in I certainly expected a struggle, but jeez my brain hurts a bit at the moment. 

I'm sure I'll work it out one way or another. Plenty of time. No hurry. She'll be right!

Thanks for your comment, Roger. I appreciate you taking the time.

I did see the joystick option - tidy, if tethered.

For now, I'm going to persist with the target of a Pi, wireless control scheme and see if it ends in tears. 

Philosophically speaking, I'm OK with a struggle.  Didn't Camus say something like "The struggle to control the bytes is enough to fill a man's heart". (I'm long-time fan of Sisyphus' work with stick / rock / mountain.)

Or, throwing back fifty years and channelling Nixon:

I choose the Pi-based control system, not because it is easy but because it is hard.

Doh! Thanks, Ken. I need to bone up on my historical presidential speeches evidently.

I think I was half-watching a speech (or press conference) by Nixon about Apollo 8 when I heard it - maybe he was quoting Kennedy???

Or I just mashed a bunch of loosely related historical events together and came up with my own version.

If it helps, I've recently added an option for much simpler control via Arduino instead of web server running on Raspberry Pi. Joystick -> Arduino -> Servo control board. The upside is simplicity, the downside is tethered wired controller, not wireless.

Wiring diagram is up on Sawppy's Github /docs folder and code under /arduino_sawppy folder.
