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."
"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.
