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.
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.

Lol I feel ya. I ended up making and selling electronics kits to fund the hobby somewhat.
I have been using cheap vintage oscilloscopes the whole time.
Not sure what they go for now but $100 for a 20MHz scope and $200 for a 100MHz was what it was several years ago. Cheapest I got off a buddy for $40. I am still using that one.
Sometimes I fix broken ones and sell them. One time I got one that they thought was broken but turned out it was just the basic settings. I like trying different ones so I have gone through a dozen or so by now.
Now* that I think about it, o-scopes are a whole other hobby lol.
Anyway. Yeah by the time you get the test gear and enough sensors and microcontrollers and whatever it adds up.
Right now I’m working on a power supply design for a 50W class D stereo. Found out big toroidal transformers are not cheap. Oof. And enclosures big enough (especially if labeled “amplifier” or “stereo”) are ridiculously spendy.
My next project is to make an oscilloscope clock
This sounds like the point where you dive into the next rabbit hole of making enclures. At least I could see that happening.
I’m looking to make some wooden enclosures for some things myself.
Just be careful or you might go fullDIY Perks after long
Erk. I got into this. What’s the tipping point that gets you eyeing oscilloscopes? I’m at the fiddly smd stage.
My next step is custom boards and smds, and an oscilloscope seems like a good way to diagnose when reflow goes wrong. I already have had some fights with I2C using dev boards. But really I’m eyeing one because I have allusions about doing fine calibration on analog sensors.
I should add that I’ve been talking myself out of an oscilloscope for 2+ years now. I don’t REALLY need one.
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
