Fun stuff. You kids don't know how lucky you are to have really capable MCU's for just a few bucks. :-)

It is kind of the ultimate "not a TOE[1]" example yet.

[1] TOE or TCP Offload Engine was a dedicated peripheral card that implements both the layer 1 (MAC), layer 2 (Ethernet), and layer 3 (IP) functions as a co-processing element to relieve the 'main' CPU the burden of doing all that.

Any suggestions for people not used to tinkering with hardware? I would like to play I think, but I have a lack of imagination regarding potential projects/goals.

I have plenty of ideas, I'm just super lazy!

I'd like to hook up a rain sensor to a skylight to close it when it rains (needs a little motor, too), and then also hook it up to weather forecasts.

I currently have to switch on my TV, surround set and a laptop, and then push multiple buttons to switch to/from a firestick. I'd like to automate that, so I can just switch it on/off and switch the source easily. Also if the system is in an unknown state (tv on, but using the incorrect HDMI input and the surround set if switched off, etc.), which is what the naive solution using a "fingerbot" and a IR blaster hooked up to godawful tuya stuff doesn't do.

Build a GPS-synchronized flip clock.

Add remote control door opening without destroying my flat's intercom system.

Mostly kinda boring home automation stuff, but would be worth it for tinkering.

As someone who is only mildly bullish about AI, my hope is that such ultra custom HA will be more common, and no longer limited fo the 0.1% and software engineers.
