🎛️ SCT-80 Vintage Tape Deck Plexamp Build

This project converts a 1980s Realistic SCT-80 stereo cassette deck into a modern streaming music player powered by a Raspberry Pi running Plexamp Headless. It uses the original buttons, meters, and shell—blending analog charm with digital brains.

🛠️ What It Does

• Raspberry Pi 3 embedded in the tape deck
• Runs Plexamp in headless mode (via odinb install)
• All original front panel buttons and LEDs repurposed through GPIO
• USB DAC feeds audio through the original RCA jacks
• 4” HDMI display replaces the tape window, shows album art and playback info
• Physical button controls for Play, Stop, Next, etc.
• LED feedback for playback status
• Relay-based screen power (screen only turns on when the deck is powered)
• Entire system mounts inside the original SCT-80 chassis
