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.

Esp8266, but I realized my PC was using too much idle power when I wasn't around so I slapped it to an Arduino Leonardo to emulate sleep/wake keyboard combos so I can sleep/wake the machine via home assistant

that's certainly one way to do it 🙂 the newer esp32-s2 and s3 also support native usb, if you ever want a smaller package

Like you can emulate a keyboard off of them? That'd be neat for maannyy projects I envision.

I just have like a reel of esp-01s on hand and had a spare Leonardo so it was just what I had on hand.

I might pair it down all the way and have the machine open a socket to listen for a sleep command and get wake-on-lan going and get it all working without additional hardware.

I would just use ssh, then you can remotely tell the computer to sleep or do anything else. No need to reinvent the wheel.
