but why only 50" and not also for bigger screens?

The $159 level will do screens up to 70"

There is already a kit available here (arduino + OpenELEC I think):

Or here is a blog explaining how to do it with Raspberry Pi + XBMC:

It made the front page of Raspberry.org this month:

And you can find a current discussion on people experimenting here:

Here is another project.

How difficult would it be for someone to produce an ambient lighting "control unit" that has HDMI in and HDMI out (aka HDMI pass through, analysing the colours of HDMI "in"), so that it could work with any HDMI source? That would surely be the ideal solution.

I agree, this is why I've never bothered with "Ambi-light" solutions, I have more devices connected to my tv than just an XBMC box. You get use to the effect when using XBMC and then when you change over to using say a games console it's jarring that the effect is no longer there.

Well, on the lightpack kickstarter page in their FAQ is the following explanation:

Quote:We have been working on such device however this device has nothing in common with Lightpack, neither in the way it works, nor in the components which are required, nor in the complexity. The biggest problem here are the licenses. If for example the device is going to be connected through HDMI, we’ll have to join the HDCP consortium, which means buying expensive splitters, security keys etc which would allow us to decode the signal. the next step would include finding ways to evade existing patents (by Philips) which cover the methods and principles of analyzing the “raw” signal in the cable. If this doesn't work, we’ll have to go through the licensing process which of course means extra time/costs. Besides, production of multilayer PCB (minimum 4 layers) with FPGA also means extra costs, making the whole idea unprofitable. We will continue research of this topic but there is nothing to be expected at this moment. Anyway, the new device (if created) will be something else compared to Lightpack.

So it is possible, but I doubt it would be affordable. The lightpack product looks very interesting however.

No doubt more complex to design, but infinitely more useful and easier to use. Hard to imagine how much more expensive HDMI would be when you have the £25 HDMI based Raspberry Pi and HDMI is not their most significant cost.

I would buy a Hdmi based sampling device in a instant... The pulse eight HDMI cec adapter passes through HDMIsignals and is reasonably priced.

The Simavision kickstarter was canceled, the Lightpack kickstarter has reached it's funding goal with 29 days still to go. I'm a little disappointed that Simavision was canceled since it fit my uses perfectly. Right now I'm backing Lightpack, but unless I see some improvements in it I'm going to pull my funding and give it a go myself with one of the Boblight guides.

From the sounds of it, Simavision hadn't developed the required software yet, nor even created a prototype of the hardware so it seems to have been far too premature to have been on Kickstarter, plus Lightpack is much further down the development path and does pretty much everything that Simavision planned to do.

Still, an HDMI-enabled unit would totally kick arse. Using something like Lightpack with only a media streaming device seems like a total waste - when watching "normal" TV or a game console you'd always be aware of the lack of any ambilight effect.
