- Murata make small piezo rate gyros at about 30 pounds each.
- However, they are 'rate' gyros, so it would be quite tricky
- to make an attitude sensor with them (drift etc ...)
-
- Since you talk about a hovercraft, presumably it operates
- in a 2d plane only, so I would have thought that a flux
- gate compass would have been ok. Articles on how to make them
- appear from time to time in the UK (and presumably the US)
- electronics press, if you can't afford to buy one.
-
- One source that hasn't been mentioned here before is the
- units made for Marine purposes, which have NMEA outputs. At
- least they are waterproof !
