A projector to look at your phone from afar.

The Raspberry Pi can be accessed either by wifi or ethernet depending on your needs and setup . 

It is recommended to use ethernet but i find wifi acceptable with the airplay server I used . 

For Airplay to work with the projector, I used the RPiPlay project. 

You can find it here : 

https://github.com/FD-/RPiPlay

Use this command line to have all the optimisations during the compilation.

cmake --DCMAKE_CXX_FLAGS="-O3" --DCMAKE_C_FLAGS="-O3" .. 

I then used this command line to rotate the display and have it ready for the iphone : 

./rpiplay -n dlproj -vr rpi -r 90 

which means the airplay server is named "dlproj" and its display is rotated by 90° . 

Then you can just open your iphone (or iPad or even a mac) and use the display mirroring feature of it . 

I drew a 3D enclosure that I printed, that needs a lot of improvements, and I am a bit ashamed to share it at the moment, it needs some rework. sorry for that :-/

After some soldering and putting things together I get this : 

The current assembly requires two power supplies : one for the raspberry Pi and one for the projector , both of 5V and 3A . 

I have found in my spare things a 12V 3A power supply that will fit my needs. I just need a DC-DC converter to go from 12V 3A to 5V 6A . 

I bought this one :

Making the pico projector display Raspberry Pi's screen is just as easy as typing the required command provided by TI once the python package is unzipped : 

just type : python3 ./init_parallel_mode.py
And it should display the Raspberry Pi's content on your wall.
