In this time weeks feel like months in terms of tech-related news and the new technologies.
I have been fiddling a lot with AI-driven development at work, namely using Cursor and claude all the time. Instead I started code-reviewing even more than ever – not only the code of my human teammates, but not also the code produced by AI.
Everything moves so fast that I just wanted to note a few thing. I’m pretty sure even few months from now it would feel “ugh, so much May 2026”, but still it’s important for me.
In no particular order:
Sourdough IoT sensor

I managed to build and run a sourdough IoT sensor. Okay, this have been in the works for quite a long time (at least since last summer), but I’ve got to admit using LLM sped up iterations unbelievably. Troubleshooting unknown issues now takes minutes – instead of going a long cycle the forum and waiting for a person respond. Bad news for forums, for sure, on the other hand there should be some real communication and sharing happening now instead of newbies asking the same questions over and over again. Was especially surprising and valuable to find it out in the Arduino context.
So what I built? A system is of 4 main components – IoT sensor, IoT message broker, the web-server storing the reading into a database and a mobile application sending push-notifications on important events (like sourdough starting to fall down).
I’m pretty happy with the sensor – based on ESP8266 (Wemos D1 mini) it fulfils the requirements of being ultra-low power (by going into deep sleep between transmissions, which are done using ESP-NOW), uses time-of-light for the measurements, rechargeable, transmits data through the fridge door and can sit on a battery for weeks (estimated).
