Display Degrees of rotation.

Hi Bobw55,
As a ham (WB6NSN) I can appreciate the need to know where the antenna is pointed. One other possible solution is to use a compass module such as the R1655. Here is a link with everything: http://www.robsonco.com/Dinsmore/Untitled_5.html

For me, I slipped the sensor into a plastic tube and sealed it.
The accuracy is 1/10 of 1 degree.

What a great idea!

Ramius , My only concern would be the close proximity to the antenna during transmit. The flux coils may be over driven....

Hi Dave,
Actually the R1655 sensor is actually 2 HAL effect transistors and a permanent magnet so there are no coils. The compass works next to a 5 watt 1.2GHZ transmitter with no effect. On the compass PC board the sensor is mounted right on top of the A/D converter to keep the connections as short as possible just to avoid any noise since the compass is in an R/C submarine with a lot of DC motors and there is a bypass capacitor on the same board with the sensor and A/D. I used two each 3-wire shielded audio cables between the compass and the PIC. I believe you would be just fine and you could also include some ferrite beads if you wish. Hope this helps, Ed

I had thought about using a compass sensor. Still like the idea. Most I found were on the expensive side, not to mention I was just getting my feet wet messing with PICs and programming. Should I ever decide to redo things that may be the way to go. Would like to see some pictures as to how you mounted yours.
