As my ambilight project has finished i thought i would share it with you.
My goal was to make a frame which has a WAF, because at certain points in the livingroom you can see the sides of my tv.
Its made of aluminium U-profiles with inside measurement of 12mm (15mm outside) and the top a flat strip of 15 . This because of ventilation. Drilled 100 holes of 12mm.
I see a lot of people construct the ambilight with duct-tape and ti-wraps. Which, at the end accomplish the purpose. But i think when you have a nice Home theatre setup investigate a bit of more labor to make a nice frame.
