Reddit user Unchecked_arrogance made a wireless receiver out of an old Sony cassette deck. One of the cassette compartments was converted into a touchscreen display running a Raspberry Pi. At the same time, the functionality of playing cassettes was retained in the second compartment; the cassette part works independently of the digital part.
The enthusiast’s idea was inspired by other craftsmen who did something similar using a smartphone. However, using a Raspberry Pi with two decks makes it possible to retain the original functionality.
The Raspberry Pi receives power through a direct connection to the deck's transformer. This means the device can be used without turning on the deck itself. The receiver can use Wi-Fi, but a network cable will provide a more stable connection. Unchecked_arrogance also created several ports on the rear panel: Ethernet and USB, through which both analog and digital signals are output. The enthusiast was considering adding a DAC to the Pi, but is currently using a USB DAC.
For the project we used a Raspberry Pi 3 B+ and a Sony TC-WR770 tape deck, which has two slots for cassettes. Instead of one Unchecked_arrogance set 4.3″ touch panel with custom plexiglass frame, plus SSD for media storage.
“I would like the physical deck buttons to work. I know this is entirely possible with the Pi's GPIO, but I lack both programming and electronics skills so the buttons are greyed out for now, but who knows, maybe I'll add this feature in the future.”

The project uses the MoOde Audio Player, which contains a number of useful functions for streaming media and supports UPnP, Bluetooth, Spotify and the like. It has a user-friendly interface that can be controlled using the touch panel. It can also be controlled via the network.
