[PSUBS-MAILIST] compass

[Jon Wallace via Personal_Submersibles]

Hank,
I use HMC6343 tilt compensated compass from Honeywell, with arduino or Raspberry pi microprocessor.  Display can be in many formats.  These are sometimes hard to get but looks like CANAKIT has some.
Compass with Tilt Compensation - HMC6343

 Ian, Thank you, sorry about the sharp bracket.  I will mount the new one on a plastic pole behind the CTHank

Hi Hank!
you could google for "Fluxgate compass" and see what you're comfortable with from an electronics point of view.
You could build your own for ~$50 ($15 for compass, ~ $10 for microcontroller, ~$20 for a display):https://www.adafruit.com/product/1120
But I imagine you'd prefer something more turn key, like:https://www.starmarinedepot.com/clipper-compass-system-w%2Fremovable-fluxgate-sensor.html
The sensor would need mounted outside, away from the hull, like a regular compass.
Cheers!  Ian.P.S.:  Please make it less sharp that the current compass mounting bracket on Gamma. :-)

Hi All,It is time to deal with a compass for Gamma.  I would like a solid state compass with no moving parts.  Jon, I think you mentioned I could do something for 200 dollars?  Any ideas are welcome.Hank
