I’ve been working on ScratchTJ, a DIY digital turntable built with a Raspberry Pi and Arduino Nano. It’s based on the open-source SC1000 code, but with some hardware changes and tweaks to make it easier to build and customize.
It runs on a Raspberry Pi 2 with an AudioInjector sound card, a small LCD screen, a rotary encoder, and even an old hard-drive platter as the “deck.” The goal is to make a simple, open, and affordable way to experiment with scratching and mixing — no fancy gear required.
It’s still in progress, but it works pretty well and has been a fun way to explore DIY DJ tech and embedded audio.
