What is your "inexpensive" hobby that turned out to be expensive/ you gradually invested lots of money into?
What is your "inexpensive" hobby that turned out to be expensive/ you gradually invested lots of money into?
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.

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
Good soldering gear already makes me wince. I couldn't imagine paying $500+ for an oscilloscope.
Fortunately I'm more interested in the software side of things... thank God nobody charges for programming toolchains anymore.
Same. I'm lucky for software to be my hobby/career. It's practically free. Contrary to popular misconception, it doesn't require any kind of special or more powerful hardware (for most dev, at least). Maybe $150 for a second monitor, for sanity, but that's not actually necessary.
...I mean, I do have good hardware too, but that's for my gaming hobby, not my software hobby.
Can you recommend any good soldering gear for an intermediate level? I've done plenty of soldering over the years but have always used crappy low end products. It's always been a struggle to properly do a clean-true solder (not just heating the solder like I see everywhere) even though I try to meticulously maintain my equipment. I'm hoping that it's just the equipment I use and a higher end one will make things a breeze like I see the professional's use.
It's really a pain in my ass. On top of maintaining the equipment I have whole setups I've constructed to hold wires and equipment snugly so I can properly apply heat. I purchased a high temp kit but it's cheap as well and still sometimes run into the same problem, with the smaller components and projects though I'm afraid to use it and overheat something that can't handle it.
yeah I got a fancy lab power supply but stopped at oscilloscopes, those things are expensive.
it's still cheap and fun to do a lot of stuff, but now I wanna build a sound-card based oscilloscope.
I haven't bought an oscilloscope yet either, but I keep window shopping.
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.
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.
My next project is to make an oscilloscope clock
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.
