hello everybody.. im a total newbie in the leds world.. but i love it so far.
i want to build a letters and number display..
and i was looking at the neopixel section, and for my purposes i thought the neopixel strip 144 was the right one..
i have some questions though..
1) can i run 100 led strips simultaneously?
2) can i cut some in half? (the screen is supposed to be 1,50 mts.)
3) what type of controller i need to run 100 simultaneously?
4) what type of power supply i need?
5) do i need something else?
thanks!!

Re: newbie with NeoPixel Strip 144 questions.
100 strips of 144 pixels is 14400 pixels total.
Each pixel would require 3 bytes of memory (43200 bytes) and 60 mA at full brightness (864 Amps )
Your best bet for driving this many is probably a Teensy 3.1 with OctoWS2811

The 144 strips are made in two sections joined in the center. If you are careful, you can de-solder the join and drive each half separately.

The strips don't require any special cooling.

Re: newbie with NeoPixel Strip 144 questions.

Re: newbie with NeoPixel Strip 144 questions.
The small matrix is 5" square, the medium matrix is 7.5" square.
We don't have any plans for NeoPixel matrices larger than the 8x8 at this time, but you can chain the ouput from one matrix to the input of the next.
