I’m interested in case building but to let it live outside.
My end goal would be to have small solar panels within the case so it could charge small batteries and power itself.
It would have to be impermeable as well.
Work has been keeping me away from this project but I’ll get to it, eventually.
If anyone advance in this subject, please share your learnings.
Every once in a while I see an RPi Zero WH at Microcenter, but they do seem to be in short supply. If you don’t mind soldering, both the regular RPi Zero and RPi Zero 2 work. If you use the RPi Zero 2, use MIX_TARGET=rpi3a instead of MIX_TARGET=rpi0. In case you’re wondering, the RPi Zero 2 is really similar to a Raspberry Pi 3A except for its shape and size.
The other Raspberry Pis will also work for the book with modifications to the MIX_TARGET lines. The nice thing about the Pi Zeros are that one USB cable can provide power and networking. This other Pis take a couple more steps to set up the first time (mostly if you need WiFi), but are totally doable.
One last note: the Raspberry Pi 4 can also be run with power/networking over one USB C cable if your computer can power it. It uses quite a bit more power than the Pi Zeros, but it does seem to work for many of us.
Hope this helps!
Glad that you enjoyed the book and the project! That’s a mighty slick looking dashboard

As for a case…to be honest I didn’t find anything that I really liked or that fit all the parts. So I just leave it out on my desk on top of some anti-static bags. I haven’t explored the HomeKit route…but that does look really interesting and it seems like a natural next step for the project 
I used this solderless kit on my raspberry and it worked perfectly GPIO Hammer Headers - Solderless Raspberry Pi Connectors [Male + Female + Installation Jig] : Adafruit Industries, Unique & fun DIY electronics and kits.
I’m trying to figure out which sensors I can get my hands on, to get this project done. A few questions I have:
Noob questions, I’m sure, but I’m curious anyway
seems to be available here: https://www.digikey.de/en/products/detail/vishay-semiconductor-opto-division/VEML6030-SB/8573326
If its just the IC it’ll work. But the connectors may be different. Post a link and I can tell you what to do.
That sensor you’re referring to doesn’t seem to have a qwiic connector. I think that VEML6030 sensor isn’t much used anymore.
I’m also having a small issue with SGP40 sensor.
I’ve got the other two sensors detected.
Circuit.I2C.detect_devices()
Devices on I2C bus "i2c-1":
* 72 (0x48)
* 119 (0x77)
2 devices detected on 1 I2C buses
but the SGP40 shows only a few times.
How come? Am I missing something?
