Akorát mi tak přichází na mysl, a nemohu na to přijít ... k čemu je KU..A na hrnci dobrá WiFi ...
Finally there is DOOM on a Cooking Pot...
Nice hacking challenge of a way over-engineered "Smart-device"!
Inside we can find 4 SoC's from 4 companies:
Heat control via STM32F031
Input button via PIC18F8..
Wifi via ESP32
Main FW Renesas 400Mhz ARM A9

Happy Solstice!! This pinhole paper negative solargraph has been exposing since the summer solstice, 6 months ago. Facing due west you can see the sun move south across the sky as the days got shorter. #solargraphy #pinhole #photography

Mám rád večerní zimní procházky, zvláště když mírně mrzne.
Nikde ani živáčka, nikde ani mrtváčka, sníh křupe po každém kroku.
Je tam takový klid ...

An incredible display of #LightPillars last night here in -20°c #Sweden. Stretching right to the zenith from all around, see the photo looking straight up at the converging pillars!

Just before Christmas, I finally put up the amazing Fibbinocci spiral flower light sculpture that I got from @evilgeniuslabs.org. Visitors to the house have raved about its patterns and how it adds a pleasant accent to our family den.
