- Pixel display for patterns and sprites - Show NES Tetris in huge pixels - Some pixelflut

Code: https://github.com/deepestcyber/rgb-tetris-wall

• MDF/HDF walls + ground 5mm, acrylic top 3mm, Transparentpapier below acrylic top
• Modules 40x40cm, 8x8px
• OR one piece 80*120cm, 16x24px
• for modules: 3mm outer wall, 6mm inner wall, 6mm base (to not get too heavy), 3mm acrylic top
• BUILD THE WALL!

• Arduino Mega based (sufficient memory limit, fast IO control)
• FastLED library
• SPI in for image-stream, 115200+ baud rate: 24x16px x 50 or 60Hz x 6bit + control bit(s)
• OR USB/serial for image-stream up to 115200 baud rate: 30Hz
• Analog inputs for mode switch: Video/Image/Music/Pattern + pattern_program selection
• Pattern mode: hard-coded RGB rainbow patterns
• Music mode: sound detection + appropriate patterns

• RasPi based
• NES signal:
  • A/D converter (svideo → USB)
  • opt for 50/60Hz, 64 colours, perhaps accept 30Hz
  • logic for reading tetris game state (block positions, next block, score)
• Image presentation:
  • opt for 24bit colours
  • web interface for uploading pictures
• Trigger Rainbow/Music mode

• Prepare for 4 x 18A/12V power lines (overall around 72A/864W)
  • This allows for 0.02x24x16x9 leds (=69.12A)
  • Cheaper option: 2 instead of 3 strips per cell: 46.08A → only 2.88A per column
  • Central power unit, but separate power strip for every column (16x)
  • Organised as 4×2 molex connector
• Case houses: power unit, raspi, arduino, power switch, 1x mode switch button, 2x pattern/submode switch buttons, 2x speed switch buttons, 2x brightness switch buttons, 1x power switch, 1x child-secure switch (buttons only work, when switch enabled)

1. Compile pyv4l @ raspi (needs v4l-dev), see ~/rgb-text-wall/download/pyv4l/
2. Integrate SPI prototype into rgb-tetris-wall code
3. Fix YCrCb conversion in streaming tool (see streaming/encoding.py)
4. Build remaining case parts
5. Complete the base detection (music mode) und develop nice visual patterns for that
6. Acquire good Potentiometer
