Led Floor
How to turn the 11 windows of the hacklab into a big led display ?
- what have we got to do it ?
- Windows that are H189xW95.5 centimeters
- 1000 red leds
- loads of RJ45 and old IDE/SCSI/floppy buses
- what we need ?
- a system to control each diode (or group of diodes) independantly
- that is not too expensive
Solution #1
use a TLC5940NT that can control about 16 LED each
* datasheet: http://datasheet.octopart.com/TLC5940NT-Texas-Instruments-datasheet-153017.pdf * schematic: http://webhome.csc.uvic.ca/~mcheng/samples/led_wheel/images/hack_schematic.jpg * O(price) = $180 for the 64*TLC5940NT, so we'll need also several protoboard to be cut to bind them on.
Solution #2
use the snootlab's i2c led driver solution that can control 16 LED each
* 64*i2c led driver = 9.95*64 = 636.80 * 1*i2c shield = 17.95 * 1 ardunio = 20 * O(price) = 674.75 euros
Solution #3
use shift registers... ?
Solution #4
use two Peggy 2 board :
* 2* http://evilmadscience.com/tinykitlist/157 * O(price) = 95*2 = $180
Solution #5
* 42 ?
