TTGO T-Beam als LoRa APRS Tracker

The TTGO T-Beam as LoRa APRS Tracker for Ham Radio usage

1.) Get TTGO T-Beam from here

https://de.aliexpress.com/item/TTGO-T-Strahl-ESP32-433-868-915-mhz-WiFi-drahtlose-Bluetooth-Modul-ESP-32-GPS-NEO/32875743018.html

2.) First Test with onboard GPS

First Test with GPS – received data to Serial (via USB to PC) out – code from here https://github.com/LilyGO/TTGO-T-Beam
Attention: change all “Serial1” to GPSSerial1 or similar – Serial1 is already defined in GPS.ino!!!!

Raspi als Wetterserver neu aufsetzen

  1. Raspi auf SD card installieren
  2. USB Stick als Drive verwenden (hält länger)
    https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=44177
  3. rrdtool installieren
  4. nginx installieren
  5. Datenbank “waermepumpe_temps.rrd”, “write_waermepumpe_image.sh” kopieren
  6. als nächstes Kommunikation zum Arduino mit NRF24 aufbauen
  7. RF24 installieren:
    http://et92.de/2014/08/kommunikation-von-arduino-zu-raspberry-pi-via-nrf24l01-und-rf24-library/
  8. “a” compilieren – innerhalb der RF24 examples; => LIB += -lrrd im Makefile hinzufügen!!!
  9. python installieren
  10. mit pip pywws holen
  11. libusb installieren und
    pip install pyusb --pre
  12. gnuplot installieren

Raspi Zero W – als Entfernungsmesser und Geigerzaehler

Achtung: prüfen ob Programme GPIO_GENx, GPIOxx oder nur die Pinnummer verwenden ;-)!

Hier die Nummerierung aller Varianten!

Verbindung Raspberry Zero W <-> GC10 Geiger Zähler/Counter

Stromversorgung des GC10 durch Raspberry Zero!

Das Programm zum Testen der HC-SR04 kommt von HIER.
