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 can recommend a 'Hacker Boxes'[1] subscription. It's $44/month currently, every month you'll get all the parts to build some gizmo or project and a full list of instructions. The prerequisites are that you know how to solder and have a soldering iron, and have a computer you can run the Arduino IDE on (even a Raspberry Pi can do that these days).

If you don't know how to solder the Hacker Boxes folks have a soldering workshop kit that includes an iron[2], but many maker spaces will do soldering clinics. Soldering irons are available as cheap[3] and more expensive[4] (and ludicrous[5]). The Arduino IDE runs on pretty much anything (Linux, MacOS, Windows).
