I guess that depends on your definition, but I don't know of a site that specifically keeps to that stuff.
If I were going to build stuff to be a pain in the ass, there are some options.
First, if you want to fuck with cameras, you need to build an IR hat. It's a dead simple and cheap project so I'd probably start there.
Then, I guess there are some USB keys. One is just a bunch of capacitors set to charge all the way then dump that current back through the laptop. That's a simple project.
Maybe, while doing USB keys, I'd do an ATTiny85 Rubber Ducky. Why not?
Once you break into Arduino programming, you may as well make an ESP8266 WiFi Deauth keychain.
I can't name a single page for those kinds of projects, but they're out there.
