Whoever needs this in the future to set the uid on a Chinese gen3 mifare nfc clone (s50 type) with an acr122u:

Instead of using weird Chinese and windows only software, send this APDU to the card (I used nfc-tools for Mac):

ff00000017d44290f0cccc10<uid>00648e859441103807

I'm not sure why the additional prefix command is needed, it might be an instruction to the reader itself?

The 90f0cccc10 part is documented here and writes block 0 of the card.

So, here's my last #rabbithole : I bought an #epaper display to use with #esphome . It's a cheap #waveshare compatible 3 colour #e-ink (BWR, black white and red), the HINK-E075A01. Unfortunately I discovered that the esphome waveshare component supports only the B/W verson.
It works in black&white, but my #display is very slow due to the added red colour, and anyway I hate leaving features on the table...
So I decided to develop a driver, for an OS I barely know (esphome), in a language I barely know (C), for a platform I barely know (ESP32). I expected it to be fun 😅

Having some time to reflect on learning fro m @ACCUConf . Searching for @kevlin 's writing on exceptions and modularity (after listening in on a hallway conversation #PacMan worked well). Finding some related writing and adding notes. Enjoyed reading "Use uncertainty as a driver" kevlinhenney.medium.com/faq-wh in this #RabbitHole

Hallo schlaues Fediverse, ich tauche gerade in ein völlig absurdes #Rabbithole und mein M1 Macbook hat dank #LlmStudio und #Ollama seinen Lüfter wiederentdeckt… Aktuell ist lokal bei #LLM mit 8-12b Schluss (32GB Ram). Gibt es irgendwo #Benchmarks die mir bitte ausreden, dass das mit einem M4 >48GB RAM drastisch besser wird? Oder wäre was ganz anderes schlauer? Oder anderes Hobby? Muss Mobil (erreichbar) sein, weil zu unsteter Lebenswandel für ein Desktop. Empfehlungen gern in den Kommentaren.
