Build a retro radio that talks in riddles with a Raspberry Pi

Designed to be part of an ‘escape room’, the Retro Radio Riddle is a retro radio set with it’s insides taken out and replaced with a Raspberry Pi and some custom circuitry. As the user twists the dial, they find riddles hidden inside the white static noise and solve them using the three buttons on the front of the set. Once all the riddles have been solved, a secret compartment pops open to reveal the next ‘clue’ or perhaps a key. Read more about this intriguing device over at Instructables.
