AtmoHue - BETA - Philips Hue support for AtmoLight & AtmoWin (1 Viewer)

No problem, be careful not to buy any of those fake chinese ones and depending on your screen size I would buy a whole spindle as you get connectors on both ends then
Some even have the resistor and power connector already attached which means you would only have to solder the corners, bought mine from a local store:

Lightning303 also has a guide for it here:

My DIY post is about SEDU not Arduino .
But, look what just arrived per mail.

Arduino Micro clone


The difference to a Pi should be obvious, no outputs like hdmi or sound, no input like ethernet.
Arduinos are boards with a micro controller, there is no OS installed. You write code and that code is running directly on the chip. Even though this board only has 16MHz clock, it is able to drive WS2812B leds which the PI with its 1GHz cant.

Looks good, can't wait for the fakeHue device
They did make some progress on rPI + WS2812 recently but due to the way the OS works its not gonna work directly even with the higher clocks, detailed explanation by the Adafruit people:

So,

Lights
Arduino
rPi

and a power supply is all that is needed? I'm guessing the Arduino needs its own supply as it needs more than the 5v the rPi and LEDs need? Or can you just put a resistor in between the rPi and LEDs and get a higher output supply? I'm concerned about mains plug space behind my AV setup

Is that literally all that is needed? Thanks!

In this setup, you can power the Pi using a normal phone charger and use an extra power supply for arduino + leds. You could also use one powersupply for all of them. You just have to take into account all of their load. All run on 5V so no problem there.
Im going to make my point again, that if you are not interested in HDMI capture i dont see the benefits in adding the Pi.

Some sites recommend adding a resistor in series with the data line and a capacitor between 5v and gnd. This is to protect the leds. As @HomeY can attest, they like dying.
Have a look here: https://learn.sparkfun.com/tutorials/ws2812-breakout-hookup-guide

So these items and you should be good. Given that you have a soldering iron, solder and some wires.

Curious. The strips say 14.4w per metre and 5v. (14.4W*4M)/5V = 11.5A no? How does a mobile charger handle that draw? Or am I calculating that wrong? I thought a charger would only put out a few amps.

Also, FakeHue? Tell me that will let you create a Friends of Hue Lightstrip controllable with the bridge and Hue app but made of your own LEDs?

Like Lightning303 said a good power supply for the leds as you can't drive them off the Arduino, using a 5V 7A myself which is still in brick form to allow for easy placement behind an TV.
Some shops add the resistor already but this guide explains how you need to build and attach the WS2812 leds to the arduino:

http://www.tweaking4all.com/hardware/arduino/arduino-ws2812-led/

Some add an capacitor but that one is optional however the resistor is required as otherwise you're gonna burn thru the leds easily
For easy removal I placed mine on one side curved plastic rails (local hardware store) and attached the leds and rails themselves with velcro, also for the corners I used the same click connectors for the corners like the above guide.
Be careful when soldering the corners as the leds are close to the connectors so best to use a low powered soldering iron.

Made a new thread for Hyperion and will add more info today and next week:

How does a mobile charger handle that draw?

Sorry, i wasnt clear enough,

Either use:
Phone charger for PI AND bigger power supply for arduino + leds
or
Big powersupply for everything.

Also, FakeHue? Tell me that will let you create a Friends of Hue Lightstrip controllable with the bridge and Hue app but made of your own LEDs?

No, at least not my project .

AtmoLight 1.4.0.0 is now officially released , more info in the release thread:

https://forum.team-mediaportal.com/threads/atmolight-1-14-0-0-2014-11-23.125633/page-6#post-1111698

You can get this AtmoLight release via the Mediaportal Extension Manager, it includes a few fixes for Hue as well.

Still working on AtmoHue and currently adding / testing the following:

- Use HueAPI from WinHue for additional features and performance enhancements.
- OSMC support, having a tough time integrating this as it will require some changes to how we manage the leds (grouping etc..) so going slowly.
- New Listview options for managing leds.

The HueAPI part should hopefully be done this weekend if it turns out to work better as well as the new listview
