We have some important news to share about HackSpace: Issue 81 was the last issue of HackSpace as a standalone magazine, and HackSpace has become part of The MagPi, the official Raspberry Pi magazine. Starting with issue 145, We’ll be adding pages to The MagPi to make room for the stories and tutorials you’ve come to expect from HackSpace.

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.
