Pajoniiir, developed by Daniel Vučinović, is a portable system designed to replace a laptop in a DJ booth. It runs on an ESP32-P4 microcontroller, a 4.3-inch touchscreen, a Pioneer DDJ-FLX4 controller, a Rekordbox music library, and a PCM5102A DAC module.
The system processes commands from the DJ controller and plays tracks in the following formats:
- MP3
- WAV
- FLAC
Pajoniiir displays track waveforms and other controls on the screen and costs $50.
Why it matters
The project is significant because it demonstrates that the tasks handled by a laptop during a DJ performance can be consolidated into a smaller and more portable setup. This raises the possibility of choosing a system built for a specific use instead of a general-purpose computer, particularly for DJs looking to simplify their equipment and those following microcontroller-based audio projects. The presence of waveforms and controls on the screen is intended to provide basic visual feedback during a performance without requiring a separate computer. However, the information provided does not make clear to what extent the project operates independently in daily use, how the music library is managed, or the scope of its compatibility with different controllers.
