    I get that it isn’t the same but when all you have is a garbage version of a memory, I’m not sure or really matters whether the representation is the original garbage or something that makes you feel less regret over not having something better.

    In my experience, the worse the photograph the better my memory of it. Probably because my mind is already used to filling in the blanks in the garbage version, so it’s constantly refreshing the memory in my mind to keep it vivid. YMMV obviously. I’m also not much of a shutterbug and prefer to commit moments to memory than try to fight with my phone to snap a photo I’ll probably never look at.

    I don’t use MQTT currently, but there’s several things you can do with it:

    • Pass some messages as plaintext for use in, say, HomeAssistant
    • Bridge meshes over the internet
    • Send/receive ProtoBuf messages from an MQTT client to the Meshtastic node and the mesh
    • Plugging in some of the mesh mapping programs to visualize the mesh

    I tried setting up MQTT with HomeAssistant but couldn’t get messages to come in correctly. Most likely my own fault but I just never got back to it as I didn’t have a specific need in mind when I was setting it up.

    Most of what I’ve dealt with were ESP32-based devices like the Heltec V3 (now V4) that have integrated LoRa radios. It should be possible to add on a SX1262 LoRa radio via SPI and flash Meshtastic firmware, but most people just start with a pre-built kit since they’re pretty inexpensive and have battery charging circuitry and everything already onboard (which you’d otherwise have to handle yourself with a vanilla ESP32).

    I started with the Heltec V3, and the V4 improves several gripes I had with it. They’re easy to get started with, lots of case designs available, and generally good entry points.

    SeeedStudio has a lot of pre-built options as well. My new daily driver is the SenseCap T1000e which is about the size of a few credit cards stacked together. Posted about it here: https://startrek.website/post/34105873

    There’s two main flavors of Meshtastic devices: ESP32-based and nRF-based. The former are generally a little less expensive and have WiFi but are a lot more power hungry.

    The nRF-based ones are more power efficient and can run longer from smaller batteries. The tradeoff is those only have Bluetooth and lack WiFi. I don’t really use WiFi with these, but it can be useful if you want to connect a node to MQTT.

    Definitely one of the “throw it on the pile” projects for me, too, but I’m for sure throwing it on the top of the pile. Have had quite a few severe storm warnings this year already and this could be pretty useful. I was originally just looking for a way to forward NWS/EAS alerts to Meshtastic from the internet, but getting them direct over-the-air is even better.

    Only complicating factor is I have to fashion or buy an antenna for ~150 Mhz since I don’t have any adapters that will fit the RTL-SDR (I’ve just used the little stock UHF TV antenna that came with it for ADS-B and other playing around).
