AH800 Tillerpilot - Which motor goes in it? Additional information about it?

[DangerousPirate]

Pot usually refers to a potentiometer or variable resistor. There may be one on the board for setting up during manufacture.
About 10mm square with a screwdriver slot for adjustment.

If there was smoke you may be able to identify the burnt looking component. The next problem is to read the identity or value as this may be unreadable if it is blackened.
There is a spare board here for a not inconsiderable cost. PCB
This could be the 'pot'

Other people have had to replace the power transistors Repair

I think mine looks different? I'll be with the boat in an hour or so, then I can take pictures.

Yes ?
2 wires onto the tillerpilot motor is all that's needed. Someone with much patience installed it inside

This is what's needed>

IBT_2 motor controller (with the heatsink)
arduido nano (just below heatsink)
raspberry pi zero 1 0r 2 W (on the right)
5v. (from usb hub as it was easy way to do it for testing)
MPU9255 9 doff gyro/compass accelerometer. Not in pic.

2 versions, tinypilot standalone or buil;t in to openplotter. Tinypilot creates hotspot for web page control or opencpn. Not sure android opencpn is working but PC opencpn activate a route & the autopilot will follow.
Will follow a route, gps course, apparent wind or true wind.

Gains & setup available from opencpn .

Wiring is the time consuming bit, software works out of the box & from user reports very likely as good control for steering a boat as you'll get at our level. Author (who wrote many of opencpn plugins & rewrote a lot of opencpn code to speed it up) is working on machine learning & AI for learning as it goes.

That is really unexpected but very welcome. Looks like a fun project and only mildly complex

30 odd quid you could build your own controller , if you can find the bits in a global shortage of everything electronic, pypilot will run fine on a pi zero 1w which should be available on ebay. Most of the work is wiring.

Thanks. I now have another project to fill my time.

I wonder if anyone has worked out a way to use the fluxgate compass already in the AH800?

Ok, I decided to wait the rain out before doing groceries and took pics now.

Fluxgate compensator is important if oyu want to sail back in time, but you have to reach 90mph!

Thought it was 88mph ??

It was a small project I discussed with my mate who repaired my AH's ........ but we never pursued it ... one of the factors we were stuck on was how to get a displayed figure based on it ? The compass in the AH is purely providing access to detect change of heading ... unlike the later ST series that can show compass reading.

I have a spare FG Compass in the Spares and Repair AH1000 .....

Been doing a little work on a PCB to mount everything on, great value from JLCPCB who will make you a board & solder on whatever surface mount components you want. Just solder on some headers to mount the boards.

Big plus of opensource is they can implement new tech straight away, much better options there days.

Someone left an ancient autohelm head by the shower block, so that compass , wharever it is, will go in the bin & hopefully reused the box/buttons for much more modern control ?

You are so lucky someone left it there for you.

it's how it goes cruising, if any dead or ancient kit by the book swap is recyclable someone will have it. ?
Just resist the urge to take the stuff you put there yourself the day before....... ?
