Devastating. My esp32's TX and RX pins are... 6 7
I spent the evening soldering pin headers onto modules. 🤓
I did several ESP32's (S3, C3, C6, H2), WCH RISC-V boards, an nRF52 (nice!nano clone), and I also assembled a single "smol Slime" (AKA a SlimeVR tracker)... though I couldn't find my stash of buttons/switches, so I improvised for testing. 😅

I will try ESPhome and see how far it takes me. But I feel like it may be rather bespoke in that I would have to program each ESP32 with its unique purpose. If I gave ten ESP32’s doing slightly different things, I am thinking it may be more flexible to build a script which covers everything needed,

Why the alleged ESP32 backdoor couldn’t happen here
If you’ve been following the news this weekend, you’ll have seen articles about a vulnerability (alleged to be an intentional backdoor) in ESP32 microcontrollers. The news is somewhat overhyped (the attacks probably require physical access) but it provides an opportunity to look at what we did in CHERIoT to eliminate this class of attack by construction.

ESP32's have secure boot options so again, it is not a platform issue but a vendor one. And if you are worried about supply chain attacks then are countless devices that could do exactly the same thing - it is not ESP specific. IMO the lack of specificity in their wording pretty damning.

S knihou od Martina Malého se budete cítit jako v dílně, okolo bude vonět tavidlo z pájky, ucítíte teplo ze zapnuté páječky a uslyšíte lehké ťukání prstů na klávesnici.
ESP32 prakticky opět skladem.

yep, but actually it looks like it is made for xtensa (esp32-S), now there is esp32-C also available which is RISCV, would be interesting to see what's missing from OCaml's official RISCV support.

When it first dropped I had it running on the ESP32-C6 (they have some examples in their repo). That being said, I think my personal favorite uses of embedded Swift are github.com/harlanhaskin... and github.com/DevilDimon/s...!

That's a good trick if you can do it! I don't know any ESP32's with an on board humidity sensor.
I assume you're just grabbing data from OpenWeather or similar?

One runs pihole, one is a build platform for arduino and esp32 and one logs data from solar panel systems (esp32’s listen for ble adv’s and pluck out the mfg extended data, then forward via udp broadcast. The pi logger adds them to a daily flat file every 2 min. Apache CGI scripts for display.)

After releasing the V1.5 ESP32 CNC Shield, i got some feedback and i´ll start to make a version to use connectors for shielded cables, as it´s a minor upgrade i will call it V.15S. Also got a question of a version to use VFD and both Mist and Flood so i will start to work on that next.

Einige Modelle des NerdMiner mit ESP32-2432S028 werden noch mit einer veralteten Firmware ausgeliefert, die nur rund 54 kH/s erreicht. Dabei lässt sich das Gerät mit wenig Aufwand auf eine aktuelle Version bringen – und erreicht dann bis zu 380 kH/s.
