I actually happened to be looking at different allsky posts online and came across your CN post and then I saw this and put 2 and 2 together.
I would love to build something like this but have some major modifications I'd do to it. Would you be able to upload the step files or F3d files for this so I can make my modifications?
thanks!
Hello, thank you very much for sharing your model. I kindly ask if you have been able to fine tune the PCB and if you would mind sharing it as well, Thanks in advance.
Regards,
Carlos

@loykastj_145194 I completely understand. I'm working through it and getting closer. A couple of questions if you can get to them.
1. For the DS18B20 temp sensor for the dew heater feedback. Did you purchase the bare IC and put it under the dew heater ring? I can't quite figure out what you did there, as I don't see the "space" you mentioned. I mistakenly purchased a probe version thinking you just stuck it underneath near the camera.
2. For the watch crystal cover for the lum sensor, I see the space inside the cover for it to fit, but what about the hole space above it? Once you add the crystal theres like a cup created, isn't water going to collect there? How did you handle that or is it not that big of a deal?
3. What did you do for the reset switch? I tried to put a switch on the RUN and GND pins on the pi board, but that wasn't working for me.
For anybody else planning or in the process of building, I've worked through most of the technical issues and can pass on any lessons learned. I'm just going to pcb breadboard the i2c interface as its only shared between the TSL2591 and BME680 sensors and just parallel wiring. So its pretty straight forward and I'm just going to mount the PCB on the inside.

Yea, I used TO-92 18dsb20 sensors, I had a bag of them from AliExpress.
The watch crystal fits on the outside of the circle. I used a tiny bead of UV cure resin and a UV lamp to cure it, so it's sealed and there isn't a well to hold water.
The AliExpress 10mm sapphire crystal fits in there perfectly.
GLOBAL_EN+GND shorted together should reboot a 4b. (edited)
