[QUOTE="Rick164, post: 1164313, member: 17766"] [B]Do I really need a separate Arduino board? If so, why?[/B] Only if you want to use WS2812 led types, these leds offer more per meter (60 to 144 p/m). Reason for Arduino is that these leds operate differently so you need some hardware in between the rPi, some have found experimental ways to connect it directly to the rPI but can't recommend it. [B]How many LEDs do I really need? [/B] Depends on personal preference but would go with 60 leds per meter for new setups as you get less blobbing on the wall (easier to distinguish transitions / scenes). So that should be around 160 leds total if my math is right :p [B]What LEDs do I need?[/B] APA102 seems the best right now although I haven't used them yet and also offer 60 leds p/m, they are a bit more expensive but are SPI based so no need for Arduino and are reported to be faster during low brightness. WS2812 if you want something cheap and is used in most setups right now, can see a few videos of those in actions in the Hyperion DIY topic. [B]Do I get the Pi configured as I know nothing about linux?[/B] With the Hyperion guide you should be fine as it explains every step, some little experience helps like making SSH connections but we have a support topic for it if need be :) [B]Is there an easy was of connecting the LEDs without soldering? [/B] SEDU has led "lego" blocks but are 30 leds per meter and expensive, no soldering required though. [B]Is it possible to use long cables and to pack the Pi and the arduino and the PSU beneath my Receiver?[/B] Long data cabels I can't recommend ( > 3mtr) as you can get interference or delays (mine simply didn't work), would keep the relatively small arduino behind the television and connect it to to the rPI behind receiver via an usb cable if possible. Long power cabels are no problem however. [/QUOTE]
