So I'm kinda a DIY guy and I like looking for cool science gadgets that would be fun to make and stuff. I've already made a negative ion generator.

I'm currently working on a wifi/bluetooth jammer, and so does anyone know any other really cool gadgets I could work on? Thanks!

You know that WiFi/bluetooth/cellphone jammers are illegal to operate in the US. Right?
