Ok so theres a lot going into this and im more or less trying

I was thinking of this exact project lately, but Im swaying towards putting a galileo or something in a backpack and interfacing it with the pipboy via bluetooth. Then I don't need to pack much into it other than a few circuits and a screen. A phone wont give you any gpio other than through aux so to make any reasonable additions you would probably need to use bluetooth anyway. Then again the backpack might ruin your whole idea of a pipboy

Someone sugested using or making a rapberry pi. Ive seen multiple theeads about these and read up on them a little. And i thought about the back pack idea myself. Kinda wanted everything in the wrist unit.

then a pi or similar microcontroller would be your best bet, something with good A/V support

Alright so ive done a marginal amount of research and followed the sudjestions and advice given and i believe what i need to create is my own system on a chip.

No, you just need to find one that does what you need it to do. Creating one would require more resources than everyone on this board has combined.

alright so im thinking of gettingthe new raspberry pi3 and then adding stuff to it. i want to be able to run linux,display onto an hd screen, and preform am/fm radio, and maybe a cb radio.

Raspberry pi is pretty overpriced for what you get. There are others that are compatible with the rpi interface.

For a one off you would typically use a fpga. Soc is for mass production
