Would I be able to ask this question on homebrew.stackexchange.com?
"I have a an issue where my hydrometer is stuck in my carboy. I can't reach it with my hand to get it out. Any ideas on how to get it out?"
I'd say yes; just for example, looking at the carboy
tag has several unclosed questions relating to equipment and not directly brewing beer.
Examples:
Carboy Dimensions
Class Carboy vs Better Bottle
Carboy Cap vs Stopper
Adding oak chips to a carboy (specifically, getting them out)
Also, while looking through these, there's even an equipment
tag you could use.
(Although, might rephrase it to "How can I get it out" vs "Any ideas," so it's more directly answerable instead of discussion. Of course, that's nitpicky.)
