I like weird stuff you can connect via USB. Either it be a LED light strip, or some other form of lighting. Maybe it’s a USB cooler for your soda pop, or a desk fan. What are some of your favorite USB desk gadgets?
How about a home-made usb cooler, would that qualify? 
hmm, I have other self-made things but I made them when I was a kid, they’re not “gadgets” though 
EDIT: uploaded pics directly, somehow the embed from my gallery broke
Sure, I’d say so. 
That’s pretty cool!
I only have boring things connected haha.
But maybe a couple things some people don’t have. A usb connector that doesn’t allow data so if I want charge my phone in airport etc no way of getting malware via the usb port and my portable ID card reader.!
