I feel like I always think of solar punk as a macro thing where a lot has to change but there are still smaller wins we can implement, what have you been doing?

Any DIY links that you have found are useful for this (before I start re’searching’. )

    I don't have any handy "start to finish" guides for this. I suppose I should start a blog, or something :)

    Basic steps:

    1. get a phone that can run PostmarketOS - https://wiki.postmarketos.org/wiki/Devices

    it does not need to run it perfectly. Camera, cell modem, even screen are completely optional. It must charge and do WiFi, only.
    2. flash PostmarketOS on the phone. Get SSH access - if the screen doesn't work, use USB ethernet emulation (during pmbootstrap init, choose USB mode = "developer"), log in, then nmtui to enter your WiFi password.
    3. optionally, reduce maximum battery charge/voltage, to prolong battery health. https://wiki.postmarketos.org/wiki/Battery_Voltage_Reduction
    4. hooray, now you have a server. Proceed setting up as if it were a VPS. It's a variant of Alpine Linux - any Alpine guide will work fine, or you could use Docker or Podman.

    Now this is something I haven't done, but you could - hook it up to a solar panel. Rely on solar during the day, and on the phone battery until it lasts. Write a shell script / cronjob / systemd unit to suspend the phone when battery level gets low. It'll get a wakeup event from hardware, when solar comes back (hopefully).
