Edit: so it turns out that every hobby can be expensive if you do it long enough.
Also I love how you talk about your hobby as some addicts.

Electronics / microcontrollers.
Took just a few months to go from, “I can make a wifi connected weather station for like $20 in components!?” to “oscilloscopes cost how much?”
Has there already grown a noteworthy Arduino/ESP Community on Lemmy?
There are quite a few but none are super active.
You can get a cheap oscilloscope that uses USB and your computer. https://www.sainsmart.com/products/sainsmart-dds-140-40m-200m-s-virtual-oscilloscope-logic-analyzer
Not that I have an electronics problem
I’m really happy I don’t have enough space for that stuff. Otherwise I would be poor. It’s hard enough to keep myself from buying another old computer.

I would love to read about this $20 weather station! Do you maybe have a link?
Mine is pretty basic but is built on the shoulders of giants. Also that $20 was from pre-pandemic / pre-chip shortage prices. I’m guessing it’s more like $35 now, or maybe high $20s from ali express.
I use Home Assistant for home automation. It has a now official addon called ESPHome for easily configuring esp devices and adding them to Home Assistant.
All the components were supported by esphome, so I just needed to write the device config and then flash the devboard via esphome (in a web browser) over the built in usb.
I 3d printed a housing for it, but you can also buy boxes. It needs airflow but also needs to stay dry. You can use a spray sealant to help avoid corrosion from ambient humidity. I skipped that step because I want to see how quickly it becomes problematic… and I should probably check on that.
Just an fyi bmp280 is not real temperature but an estimation based on air pressure.
