"Hey, wait a second, mister! Are you tryin' to get me possessed?!"

Spiritbox EVP (electronic voice phenomena) is an Arduino sketch preloaded with an oscillating frequency scanner that sweeps through the FM band and... with any luck, helps you communicate with the other side!

Don't have a dev board?!?

Any old dev board and radio module will do (check out the buyer's guide, included), and my personal setup only cost about $6 (again, check the notes for a few recommendations). Setup is a breeze -- just one jumper cable seals the deal and gets you up and running.

"But I'm a skeptic! Na-na-na-na-poo-poo!!"

Me too! But I'll tell ya what -- that's not going to get in the way of me having a sh*tload of fun. To each their own, and I'm not going to tell you how to live your life, but I think you'll have a blast with this and a little bit of imagination :).
