[PSUBS-MAILIST] gyro compass

[MerlinSub@t-online.de via Personal_Submersibles]

Air or vaccum power will not work in a sub.
Try a electric one.
24 Volt or 12 V are rare - normaly 400 volt and high frequency - you need a 
transformer.
 
But notice:
 
The get out of course after 0,5 - 2 hours. And will be normaly re-adjust by 
a magnetic one in a aircraft.
 
Ebay cheaps are often out of service / out of course. The normaly run but 
get quick out of course.
Units with work proper certificate (Airworthy) are much more expensive.
 
Buy three and select the best working - sale the rest again.

Hank, 
 
Try using a gyro compass ( or atifical horizon) from an aircraft. They sre 
either air, vaccum or electric  powered.

I am going to try to make a gyro compass, looks doable.  I don't care about 
what direction I am going-I just want to go in a strait line.  I will point 
the sub in the direction I want to go at the surface, then turn on the gyro 
and sink.   Then I can just follow the gyro.
