Specs

• 50 x 50 cm
• 16 "Pixels"
• 144 LED (5m LED stripe, cut into 3x1-pieces)
• 12 volt
• Arduino
• Shift Registers

For tests, i used 74HC_HCT595 shift registers (http://www.nxp.com/documents/data_sheet/74HC_HCT595.pdf) and uln2803a darlington arrays (http://www.ti.com/lit/ds/symlink/uln2803a.pdf). For some reason, it worked not as expected, so i bought TPIC6B595 high power shift registers. Maybe they will arrive in germany till middle of next week.

Specs to come..

• Audio Input (3,5)
• Touch (capacitive sensing, maybe reduced resolution: 4x4)
