**UPDATE** – This turned out to be a hoax. Still rather cool nonetheless.
Here is a quick and easy way to mess with fast food joints. With this neat little hack, you can take control of a fast food restaurant’s drive through. All it takes is an old toaster, a CB radio, and a little bit of solder and you’re all set.
This hack involves a quick crystal swap. Take one from a toaster and put it in a CB radio (found for a few bucks on eBay) and you’ve just tripled the number of frequencies that radio can use. In fact, it puts that radio into the same range that fast food restaurants use. Armed with that radio, you can take control of that restaurant’s drive through, allowing for some hilarious, and harmless, pranks. For more pranks like this, check out Phone Losers of America.
