I'm looking to create a projector which projects my phone screen onto a wall. I have a few requirements:

  1. 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).

  2. I'd like it to be wireless.

  3. 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).

    \$\begingroup\$ So you're asking how you can project your phone's activities onto a screen? Why not emulate a mobile device via software? Something like Bluestacks? \$\endgroup\$ – KingDuken Jan 26 '18 at 19:10

  • \$\begingroup\$ @KingDuken Bluestacks would be a good shout if I wanted to have it on my pc screen. But I'm looking to create a display that's portable & its only function is to display the phone screen. Still a good comment 'cuz Bluestacks is pretty interesting! \$\endgroup\$ – Mr. Meeseeks Jan 26 '18 at 19:25
  • \$\begingroup\$ I think it would be pretty easy to just connect a chromecast to a projector, and then cast your screen like this (support.google.com/chromecast/answer/6059461?hl=en-IN) \$\endgroup\$ – BeB00 Jan 26 '18 at 19:27

(originally a comment)

Just plug a chromecast into a projector and cast your screen
