Power Supply for 8x8x8 LED Cube and Arduino at the same time

-

hello, i'm building 8x8x8 grayscale led cube. works fine far, have 1 problem:

because cube needs lot of power, max 2-2.5a 64 bright white leds @ time (one of 8 multiplexed layers). since arduino can not provide enough amps, use external power source leds, lab power supply now. arduino powered usb, grounds connected of course. switch layers using mosfets, leds controlled using 4 tlc5940.

later, make nice box 1 power plug.
i know can use vin pin (and gnd) on arduino power it. read method needs @ least 7v, leds run on normal 5v.

i'm relatively new electronics i'm not quite sure how solve correctly. thinking use 8 or 9v power supply (wall plug adapter) supplies enough amps project. power arduino via vin pin directly supply , use voltage regulator kit transform voltage 5v led circuit.
would correct way this?
i didn't quite know search i'm sorry if discussed here before. if so, post link helpful thread?

afik if feed arduino though power plug (not usb) fine around 12v (double check specs on forum, somethink that)

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
