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’m doing a hardware interface for baby buddy. The platform is based on an esp32s3 with:

round display with touch
10x Kalih choc switches
rkjxt1f42001 (nice part, encoder+four direction)
Ambient light sensor (to adjust backlight automatically)
9-dof IMU (because why not)
battery controller and fuel gauge from TI

It was a pretty challenging design, first time soldering BGA ICs and using solder paste/stencil! Also, hard deadline :D

Will open source and publish HW and code (written in rust) soon!

I'm waiting for my https://www.seeedstudio.com/MR60BHA2-60GHz-mmWave-Sensor-Breathing-and-Heartbeat-Module-p-5945.html to arrive so that I can see what I can do with it.

After sitting idle for a long time. I finally found time to use it. I made a simple websockets app that plots the data from the starter program https://wiki.seeedstudio.com/getting_started_with_mr60bha2_mmwave_kit/. Then I made another webapp to log this data in 1 hour increments.

I zip tied it above a bassinet.

Right now the data is pretty useless but it could be fun to see what I can do with the data.
