I've buyed from china a new screen. A 2.4" Nextion smart screen. (https://nextion.tech/basic-series-introduction/).
This screen is really fantastic. It comes with an ide, and comunicate via the serial bus with the esp32. it grab the data and do a fantastic job.
You can add button and other things for a modern UI.
thank you =)

Then, the first part of the assembly is to screw the main PCB plate into the case that I printed this morning.
Then, you have to put double-sided tape to stick the battery. Hot glue will work too.
Then, we connect the elements one by one to check that everything works well.
and we can mount the next stage of components :
I will have tomorrow to design the upper part of the case with an air flow management system.
Thank you for follwing this project.

Here are somes all of the electronics components :
This is the power management with a DCDC booster from 3.7V to 5V, the 1200 li-ion battery and the TP4056 for chargement the battery. note that there is a battery monitoring system directly on the ESP32 from the TP4056 OUT terminal.
This is the ventilation system, with a 5V fan (lowered to 4V for a slow speed). and his control PCB.
This is the main board with the ESP32 DevkitC. There is a led for power indication.
This is the other face of the main board. Note that i have engraved it with my CNC and flatcam. there a protection varnish.
Here are the sensors and the Oled control screen.
Thank you. Leave a comment =)
