Unlisted: PaPiRus (see Eink), PIcade (see RPi), Petoi Bittle (unfortunately stuck in a bad state), ANAVI Fume Extractor, ANAVI Macro Pad 8, Lite3DP 3D Printer, Tomu, Fomy, Pinecil (with IronOS)
IDE setup https://github.com/espressif/esp-idf?tab=readme-ov-file#setup-build-environment
cd ~/esp/esp-idf/ && source export.sh
idf.py set-target then e.g idf.py set-target esp32c6
idf.py menuconfig to setup e.g WiFi, cf https://github.com/espressif/esp-idf/blob/master/examples/protocols/README.md#configuring-the-example
idf.py build
idf.py flash
idf.py monitor
To explore
#define BLINK_GPIO_1 4 // GPIO 4 (3rd pin)
void app_main(void)
{
gpio_reset_pin(BLINK_GPIO_1);
gpio_set_direction(BLINK_GPIO_1, GPIO_MODE_INPUT); // define as input
gpio_pulldown_en(BLINK_GPIO_1); //pull down mode, here 100K Ohm
while (1)
{
printf("%d\n", gpio_get_level(BLINK_GPIO_1)); // print GPIO status for monitor
vTaskDelay(1000 / portTICK_PERIOD_MS); // pause 1s
}
}

Replaced by Home Assistant (see below in RPi section) due to better support and existing API endpoints.
Formelly Mozilla Gateway Things

The @Raspberry_Pi 400 looks like a keyboard BUT with a computer in & extendable with electronics!

raspi-config allows to configure the WiFi network
alias newdeviceonnetwork="nmap -sP 192.168.0.* | grep report > /tmp/last; read -p 'Connect new device then press ENTER'; nmap -sP 192.168.0.* | grep report > /tmp/now; diff /tmp/last /tmp/now"
/boot partition then cd /media/fabien/boot && ~/Prototypes/connectpi.sh
echo 0 > /sys/class/leds/led1/brightness
npm i @sammachin/buildhat-nodered to get https://github.com/sammachin/buildhat-nodered installed
What if you you wanted something smaller, cheaper, lighter (as is fitting in your wallet) and even more low power to run your local metaverse node?

Networked @AFrameVR running on a @Raspberry_Pi 0 thanks to @VincentFretin's precious help! https://t.co/TPKnH38mbF pic.twitter.com/KIDb4ZqO3U
If you rely on the image made for this project (620Mb) an open metaverse WiFi should span. Connect to that new WiFi then to https://192.168.4.1/offline.html and see each other. If you want to add your own customizations connect using ssh fabien@192.168.4.1 and password metaverse.
Process to setup environment
rpi-imager to burn the 32bits image
/etc/hostapd/hostapd.conf use wpa=0 and remove what's after to make an open AP
apt install or npm install will fail
Process to generate image, useful to restore the state and make more copies.
lsblk
sudo dd if=/dev/sdXXX of=pi0.img bs=32M && sudo pishrink.sh pi0.img
xz (which supports multithreading, e.g xz -T9 pi0.img) which here went from ~3Gb to 0.6Gb
dd if=pi0.img of=/dev/sdXXX bs=32M conv=fsync
rpi-imager also, a GUI and thus more convenient for people unfamiliar with the CLI. It works also with the compressed image.
All this has been simplified as a regen bash script that uploads the resulting image back here.
To inspect the resulting image uncompress it then use partx -v -a pi0.img to make loops, e.g /dev/loop16, mount /dev/loop16p2 virtualimg then after unmount virtualimging them you can remove with partx -d /dev/loop16 again then losetup -d /dev/loop16. See https://superuser.com/a/1559197 for details.
Small improvements
$(which node) or /usr/local/bin/node is required
setcap 'cap_net_bind_service=+ep' /usr/local/bin/node to bind on port 443
export PORT=443 before starting ./server/easyrtc-server.js
sudo vi /etc/motd allows to put a bit of documentation as a welcome message
~/.npm
localepurge
resize2fs after using a partition manager to expand the partition
curl -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" -d '{"entity_id": "light.innr_fl_140_c_light"}' http://$ROOT:8123/api/services/light/turn_on
jxr fetch('/light_on')
Process to get a device working without proper support :
/developer-tools/event and listening to * all events
zha_event
/config/automation/dashboard and edit it in YAML
event_data
trigger:
- platform: event
event_type: zha_event
event_data:
device_ieee: 00:11:22:33:44:55:66:77
command: off
screen /dev/ttyUSB0 115200 to connect to e.g Petoi Bittle without using Arduino console monitor
