    Cred ca ai avea nevoie de niste motorase strep-by-step, sunt foarte precise. Problema e cum sa faci un adaptor (interconectarea) intre LNB si suportul "reglabil". Aici chiar iti trebuie inspiratie!
    Felicitari pentru idee, ar merita pusa in practica!
    Offtopic:
    Imi aduc aminte de un prieten care a facut un ploter din doua motorase de tipul asta inainte de '89, cand asemenea scule erau imposibil de procurat pe la noi (daca nu cumva erau chiar ilegale). Din pacate nu a apucat sa il faca sa mearga decat alb-negru, cu putin timp inainte de a-l face sa mearga si color a prins o "oportunitate " si a taiat-o in Australia de unde nu s-a mai intors nici in ziua de azi.

    Uite aici mai multe detalii:

    Motorasele sunt destul de ieftine, consuma putin si le gasesti usor. Mai delicat de rezolvat sunt doua probleme:
    1. Adaptorul mecanic de sustinere a LNB-ului pe suport.
    2. Controler-ele pentru motorase, ce am gasit eu pe net sunt destul de scumpe, pot ajunge la cateva sute de para. Practic ai nevoie de 2 motorase plus 2 controlere (sau un singur controler multiaxe). Primul trebuie sa asigure rotirea LNB-ului iar al doilea miscarea in/spre focar (adica sa-l apropie/departeze de focarul antenei). In plus, niste limitatoare de cursa ar fi binevenite.
