A binary device for transmitting 'slow images' on variable frequencies between 88-108 Mhz.
It runs on a raspberry pi + pi camera which takes in an interval of 1:57 min a photo and transmits the photo in a SSTV (Slow Scan Television) modulation via a Pi-box. The anetnna is a dipole calculated in realtion to the frequency you want to transmit.
Used during Dwon Dwars Dela study session in the [Weather_Station]
Inspired and with tools/scripts of:
- Grassroot mapping Publiclab : https://publiclab.org/
- Radio hardware- online + Local FM streamer p-node : https://p-node.org/documentation
- Code and soft bash tricks Rekall : https://gitlab.bertbalcaen.info/electromagic
For receiving and demodulating the images a binary device is needed + an installation of Qsstv (laptop, Linux) or Robo36 ( smertphone, Android).
