Many people have taken the Motorola Lapdock and mated it with a raspberry pi with various cable adapters. But there is a sequence that it has to be turned on in and only certain connectors work. Can you make the dock a stand alone HDMI monitor?
I have a Motorola Lapdock 100 and a raspberry pi 3. I am able to get it to work but the dock doesn't seem to have enough power for the pi. I have to plug the pi 3 into the main power, then I have to plug in some other USB device to get the dock to power on. At first I had thought about putting a full size HDMI port in the dock, but with the wires being small and the colors not matching exactly I didn't want to destroy something that I can still use.
Is there a way to make the dock power the pi 3 and independently be used as an HDMI monitor?
