I really like the idea of this wireless mouse which also works midair. It’s a do-it-yourself gadget, which means I won’t get it since I’m not any good with that stuff.
Basically all you’ll need to make it work is a normal optical mouse, batteries, some tiny plastic bottles and some fabric. It sounds simple enough actually. You’ll find a video of the process step by step here.
Aside from the fact that it looks like something a child might play with, I think it’s a great idea. I hope I can find someone to make me one!
