Built it!

The parts have slowly arrived over the last week and the only thing I was missing was the 2000mah LiPo battery, but I couldn’t wait, so I started building AirLog-E today!

Building!

I’ll go in order of how I built it!

3D Printing…

First, I 3D printed my enclosure which was super easy using the 3 included .3mf files!

E-Ink Display

I next used M2.5 Screws to screw the e-ink display into the main section along with the front plate. The cables from the display were super long so I cut those to a shorter length in preparation for the next steps.

Sensors

Then I screwed the 2 environment sensors into the enclosure.

Heatset Inserts

Next were the 4 M3 heatset inserts which go into the main section (these were super satisfying to install)

First bit of soldering

I now had to solder all 8 pins from the display to the ESP32-c6 which was very fiddly! I was also going along with a multimeter to check every connection after every new joint.

Charging

I wired up the TP4056 module to the ESP32’s BAT + and BAT - pads and attached the 2 wires to it for where the battery (which still hasn’t arrived) will go. (I’m using a slightly smaller 1600mah lipo I already had for testing!)

Sensors (again)

I actually had to wire up the sensors to the ESP32 now which was also very fiddly but I managed to get there in the end.

Firmware!

Flashing firmware

I took the code right from the github repo and compiled it in ESPhome and.. it worked!!

Firmware changes

I wanted to change some things, like:

• The VOC’s wouldn’t read because they took 80-90s to initialise, so every 10mins it’ll stay awake for an extra 30s to get a VOC reading.

NOW IT FINALLY WORKS!!

I’m gonna change more stuff with the firmware tomorrow, like adding the time (as I promised) and making the e-ink look cooler!
(I’ll also need to add in the battery when it arrives and glue in the TP4056)
