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.
that's so interesting, are you doing this at work or are you an avid gardener?
It's for hobby!
But I did work with cell cultures (with lab-grade incubators) in the past, and I am currently working with a company developing sensors for industrial systems. So, the concept of PID I learned at work recently. And at work I also write some firmware for interfacing sensors with micro-controllers.
