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 two projects going on right now (as more-or-less a newbie to ESP32s and microcontrollers/DIY electronics in general):

First, I'm working on WLED Christmas lights. I started out with a (relatively) expensive off-the-shelf controller, but haven't been able to run more than about 200 LEDs on each of the two channels it supports, which isn't enough to run all my lights without hooking multiple strands up to the same channel and letting them duplicate node addresses/mirror each other.

I'm now trying to replace that with my own DIY controller using this dev board (I think it's a generic clone of a NodeMCU-32S? IDK, I picked without much thought because it was cheap, had lots of exposed I/O pins and USB-C), a 12V->5V buck converter, and a SN74AHCT125N used as a logic level shifter (especially because my LEDs are 12V), but I've been having problems getting it to work when soldered to a perfboard even though it worked on a solderless breadboard.

Second, I got a great deal on some Matter/Thread smart light bulbs on clearance at Home Depot the other day, which means I suddenly need a "Thread Border Router" for my Home Assistant setup. So I got myself one of these, but haven't started trying to set it up yet.
