For satellite TV reception in an RV can be an expensive automatic satellite antenna buy or a simple inexpensive satellite antenna on a tripod to affix and manually align. This is usually very time-consuming, and since the antenna is outside, on the inside of the television receiver, however, one can observe the success of doing poorly.
A much more comfortable and still preiwerte solution to the presented antenna Rotor with step motor control. The control of the step motor is of a NodeMCU LUA Amica VS module with ESP8266 12F so that the operation via the Wi-Fi can be. The ESP8266 is operated as an Access Point. With a Smartphone you can control then quite simply, the antenna rotor.
In this mode, the ESP8266 is always the IP-address 192.168.4.1
The proposed program creates a WLAN with the SSID "antenna" and the password "womo12345". Of course, this may be due to Changes in the program changed.
If the antenna Rotor is supplied with current, one can find in a smartphone, in the Wi-Fi list, Wi-Fi with name "antenna". We connect with this wifi and launch a Browser App. As a URL we enter 192.168.4.1.
We should now see the following Homepage in the Browser, and see
If we are on one of the buttons to click should the antenna in the desired direction of turn.
Parts list:
- NodeMCU LUA
- stepper motor driver
- stepping motor
- voltage Converter 12V to 5V
- 2 two screw terminals
- housing 3D printing
- Camping SATELLITE system

Und woher bekomme ich das Getriebe? Ohne Mechanik, sprich Getriebe, ist das alles Makulatur. Und wie ist es mit der Vertikalsteuerung Gibt es dafür auch Ideen? So werden z. Bsp. in anderen Bereichen der Funktechnik der Mond, Meteorschwärme, Flugzeuge oder Wolken angesteuert.

Hallo,
die Stromversorgung könnte man vielleicht der Phantomspeisung des LNBs entnehmen, da die Polarisation über eine Schaltspannung von 14 bis 18 Volt eingestellt wird. Je nach Strombedarf der o.g. Schaltung sollte das gehen.

Hallo,
bei Verwendung von (größeren) Schrittmotoren ist zwingend ein (mindestens) 100µF Elko direkt an der Schrittmotorsteuerplatine (+12V Anschluss) notwendig. Sonst wird die Schrittmotorsteuerplatine zerstört. Hinweise zu diesem Phänomen finden sich in diversen Applikationsschaltungen im Internet.
Sonst eine wirklich clevere Lösung mit Potential für eigene Verbesserungen :-)
