Esar’s Ambilight clone that runs on the Papilio Pro is an awesome project, I still have one on my desk waiting to be tested. One of the challenges is HDCP protected content – but with this awesome hack it is no longer an issue!
His amazing custom Ambilight clone got profiled here, and someone asked him in the comments if it worked when High-bandwidth Digital Content Protection (HDCP) is on. [esar] lamented that it didn’t. Hackaday readers to the rescue. [Alan Hightower] and [RoyTheReaper] pointed [esar] to the fact that HDMI splitters need to decrypt and re-encrypt the signal to pass it on, and pointed him to a trick to knock out the on-board microcontroller. [esar] took off from there.
