WW2 Radio Broadcast Time Machine

This article was originally published as part of HackSpace magazine, which has since been incorporated into Raspberry Pi Official Magazine.
Adam Clark (aka Ajax Jones) has listened to quite a few of the archive
broadcasts from WW2 online, but wanted to listen to them on something more fitting and physical. "I bought a very old, non-working valve radio, and replaced the internals with a Raspberry Pi Zero on a custom 3D-printed chassis," says Adam. "The dial is used to select different years of the war, and the relevant radio broadcasts are then played out."
A quick intro to Python – short scripts, rapid results.
"To read the dial, I used an MCP3002 analogue-to-digital converter (ADC), and for the audio, I used a MAX98357 I2S Amplifier. Keeping the original speaker in use was a great stroke of luck, as the reward was an amazingly authentic sound," says Adam.
