[QUOTE="Lightning303, post: 1131554, member: 97876"] The one you linked is the original one and is fine. Some fake/cloned arduino unos use another solution for the usb communication in order to save money (using FTDI or CH340). As you seem to want to use the originial one, this however is not the case, so all is good. 1 led needs a maximum of 60mA. So 101 * 0,06A = 6A. Not sure why you want to use multiple power supplies, i would just buy one of these meanwell powersupplies and hook everything up to that. Its all 5 volt, and its more efficient, needs less room and so on. So you will need either a 6A supply for the leds plus a normal usb charger for the pi, or a 8-10A supply for everything (depends, how much extra devices you want to power aswell, e.g. capture stick, hdmi splitter and so on). Just out of curiosity, do you actually want to use the external capture function (usb video grabber and hdmi splitter and stuff)? Lots of people ask in this thread for help regarding pi and arduino, and i have the feeling that some just assume that this is the only or best way to set up an ambilight and dont even know that you only need a pi if you want to use a usb video grabber.
