I'm looking to create a projector which projects my phone screen onto a wall. I have a few requirements:
I'd like to do it using a projector with its own light source (i.e. I don't want to use a lens that focuses the phone's display to shine on the wall).
I'd like it to be wireless.
I'm not interested in the actual light source implementation: more specifically, I'd like to understand the protocol & mechanism to send the phone screen info wirelessly to an embedded device, and then how that info can be output in a format that could then be recognised by a remote projector / lcd display.
I'd essentially like it to be like this: https://www.snopes.com/photos/technology/cicret.asp, only onto a wall (rather than my arm) and the touch-screen functionality that circret has isn't necessary.
Could someone give me some suggestions as to the hardware that I could use to do this? [edit: using existing hardware to pair with my mobile device is the ideal solution]. Something I can reverse engineer is the ideal solution I have in mind: i.e. if circret was on the market, I would take out the electronics that I needed in order to project and voila. Obviously, I would like the cheapest solution. If worst came to worst: could someone give me a solution that involved me having to code something? (I'd like to do as little coding as possible).
