  • Theres a fantastic video that does over everything involved here: https://www.rtl-sdr.com/transmitting-and-receiving-meshtastic-with-sdr/

    and another one here: https://www.youtube.com/watch?v=L1VgO1OZWbs

    You can take a RTLSDR (<50$) and receive meshtastic/lora signals. Then put it though some software to “see” it. Its fascinating. The logo is actually what lora/meshtatic looks like on the spectrum.

    I was able to reproduce with an old RTLSDR V3.

    To be honest, theres nothing magical about meshtastic compared to say ham radio and meshnets. Its just using a technical amature band at a whisper (less than 1W usually) to transmit. If you want to be really technical, all you would need is a very cheap RTLSDR, some tiny transmitter, and a computer in order to reproduce “open hardware” for meshtastic. GNU-radio would help with that should anyone go that route. Its hard (to me) to do all of it, but I was able to get most of the way there about a year ago.

    I feel like there is more I can do with this that involve the lora side:

    1. Sync book pages with some sort of server(?)
    2. Update book with lora instead of wifi
    3. Meshtastic type node where you can ask the node to give you a page at a time (multiple pages?). Then you could read a book slowly through the mesh. Click “n” for next or something of that nature.
    4. Better hardware? I still have a nice ebook reader that has better battery life than this.
    5. Some way to put the device in deep sleep. Right now its designed to be turned off and keep its page. But doing something like meshtastic where the screen goes to sleep after a while might be better?
    6. Throw the code onto git…somewhere. With instructions and all that. Its Sat and it took effort just to post this. So im leaving it alone for now.

    I dont know if ill ever get to the above, but it was fun to try out. Again hope its not against the community rules! It WAS a meshtastic node and someday may go back to again.
