Hi there, really interesting looking project and I'm thinking of making one and have a few Qs I'd appreciate some help on:
How much does this cost to make (UK £) roughly?
Can you control the brightness of the LEDs/make them dimmer for a night mode?
Does it add any input lag to gaming etc?
Does it make a difference if you use a Pi Zero or 3? If so what?
Are all LEDs equal?
How do you ensure you've ordered the right capture card?
How is it turned on/off? Can that functionality be controlled automatically via HDMI CEC or similar for seamless integration?
Ideally what I'd like to make is the version where its configured via a HDMI splitter so that it can be used on multiple inputs with at least two modes of brightness for the LEDs between day time and night time watching that can be switched with ease and without the use of a computer to control the Pi. My night time viewing settings are in Eco mode so that the screen backlight is very dim and I'd prefer the Ambilight to follow the same so that it matches the screen in terms of intensity of luminosity.
I found out about this project from here:

And from what I've read the capture card can be the most problematic part of the whole project as the rest seems pretty much plug and play if you get the right parts.
Thanks
