I had a solar powered project setup with environment sensors in my shed. After a while the bugs moved into the elctronics, corrosion ensued and caused shorts which killed everything. The lesson I learned is to seal project boxes up really well. The whole boxing something up and getting power to it thing is the hardest and least enjoyable bit of hardware projects for me.

Good point and batteries, solar, exterior environments, etc are what I would consider "advanced" use cases with significant additional challenges and considerations. All of my use-cases are interior environments with the most "challenging" being garages.

Generally speaking with any kind of lower-level electronics like this frying and bricking stuff is part of the learning experience and a rite of passage.

I read this as I'm standing next to my bare esp32 with dht22 temp sensor hanging off it with DuPont wires...

Nevermind the ones in the schoolhouse, basement, chicken coop...

So, yeah, I fully agree. One day I'll buy a 3d printer but until that day, wires and some tape. Everything seems cheap enough to be sacrificial if that's the end result.
