OK, I have a 2nd Draft of a K3NG-type rotator minimalist controller based on the K3NG code (which will need some small adjustments).
?
Using Arduino Nano as the microcontroller
2 phono plug jacks to control external relay board to reverse direction of DC motor type rotators (like Yaesu G450DC or my homebrew elevation rotator)
2 photo plug jacks to provide potentially PWM 12V to motivate the DC motor in the rotator (don't need huge speed)
2 stereo 3.5mm jacks to allow input from angle-sensing potentiometers
1 two-line LCD display to show important data
4 manual buttons to allow manual azimuth or elevation control
LCD is mounted on the backside, along with the buttons; Arduino and other electronics on the "front" side that goes "down" in the box.
Power it with 13-13.8VDC; polarity protection via series diode.??
(I forgot to put in diode protection on the MOSFET outputs....I'll add that!)
?
This will get some review for a few days from me and then go to pcbway.com for first boards.? ? ?
Simultaneously I have a nascent elevation rotator coming about very inexpensively.
