It’s a bit sad how deserted this community is, would love to connect more with other makers.

Let’s rattle the cage a bit, who of you is here, and what are you working on?

I’ll start: A wireless cryptographic keystore & signer. Keys are generated with the hardware RNG and stored AES-encrypted with the user’s password, and you can request signatures via BLE.

      I have a Shelly plug on my rain barrel. It monitors the current to the pump and stops it when the barrel is empty.

        I’ve heard nothing but good things about Shelly plugs! Are you in North America? Whenever I look at them they seem kinda Euro-centric and I don’t look as hard as maybe I should…

        My whole outdoor tech ecosystem runs on 12V, I have a little solar array that keeps an old car battery topped up. It’s a 12 V pump and the solar controller has a 5V USB output that I run the esp off of.

        Can you run a Shelly off 5/12 V? Super curious about those devices

          They have some older DC stuff but most of their offerings in the US are 120vac. Their price to performance is great
