Instructions
Print:
- 2xFront SPLIT
- 2xDiffuser SPLIT
- 1xBackL SPLIT
- 1xBackR SPLIT
Print the Diffuser Screens with these settings to give the screen a horizontal “scanline” texture:
- Top/Bottom surface pattern: ALIGNED RECTILINEAR
- Internal solid infill pattern: ALIGNED RECTILINEAR
- Sparse infill pattern: ALIGNED RECTILINEAR
- Infill direction: 0
If using white filament for the Diffuser Screen, printing it on a textured plate will make it scatter more light and be dimmer. Use a smooth plate for best results. A textured plate will work great for clear filament though :)
For the LED matrix, you'll need:
- Two 8x32 or two 16x16 LED Matrices - e.g. https://aliexpress.com/item/4000544411175.html
- ESP-Wroom-32 - e.g. https://aliexpress.com/item/1005005972312714.html
- MAX4466 microphone - e.g. https://aliexpress.com/item/3256803608057399.html
or
MAX9814 microphone - e.g. https://aliexpress.com/item/3256805923391884.html - Power Supply 5V 15~60A (~15-20A will do for most uses) - e.g. https://aliexpress.com/item/1005006126703620.html
