Ideas for new Improved rotator control
Current "standard"
* 5500 or equivalent az/el rotator controller
* serial -> yaesu interface
* loadsa cables / boxes
New plan
* Keep the toggle switches from 5500 (nice n clunky) - even though a pair of centre off sprung would be more logical
* keep the analogue meters? 50mm height needed so >1u - UPDATE - No. Aim for 1U. Have a 2nd LCD display for Az/El current position
* Add in either LVB tracker or the arduino one http://ava.upuaut.net/?p=372
* Back panel - out with screw contacts and use something like http://www.altronics.com.au/connectors/pluggable-headers/?pins_3=6-pin
