In keeping with the theme of "The Day We Fight Back," MAKE has three privacy-enhancement projects you can make: an Onion Pi Tor proxy so you can browse the web anonymously anywhere you go, a mobile, anonymous file-sharing device called the Piratebox, and a personal Internet kill switch (not the kind that freedom-hater Joe Leiberman wants to install, but one you can put in your house to keep freedom-haters from snooping on you).
Put one on the wired connection between your computer and router and use it to unambiguously isolate that computer from the internet whenever you want. Or put it between your router (wireless or otherwise) and your ISP hardware to control the connection for the entire house. Sure, you could just unplug the cable, but that’s hard on the connectors, and the switch is faster to use and neater-looking, to boot.
