- I met the inventor of this device a little while ago.
- It sells for $80 in a decent number of hardware stores; you might
- want to go out to your nearest ACE or whatever and take a look.
- I don't remember the name of his company; this was their only product,
- although they sold it to Bosch for marketing in Europe/Asia.
-
- The device uses an accelerometer in solid state of some sort.
- They've got a patent on it, and aren't too keen on talking, it seems.
- (although I might have got that impression because the fellow was just
- more interested in drinking his beer than talking shop :-)
-
- Anyhow, it is based on a small (1"x2") removable unit that has
- an LCD display and a couple of buttons. Even if nothing else, you
- could decode the lines they use to output to the LCD display.
- This thing is quite accurate, as well as precise to at least 1 degree inclination.
- Two of them would give you planar information, of course.

- Joe Bob says: check it out...
