/diy/ - Do It Yourself

I'm trying to figure out if it would be feasible to build a hidden camera out of the following stuff:
>old tv/ac remote to use as shell
>camera sensor in place of the IR diode
>raspberry pi zero with wifi adapter
>old phone battery + makeshift transformer (cheaper for me) / usb power bank (more bulky and expensive)

I would like to hide it in a random pile of stuff on a bookshelf, and I can't afford to have it plugged to a wall charger. This would be an ideal usage scenario:
>want to take a peek
>send Wake-On-Lan trigger via wifi and connect to the camera via vnc or whatever else
>turn off the pi when I don't need it anymore
>...
>retrieve the remote-cam when the battery runs dry
>charge the battery and place the remote somewhere else

I did some research but I can't figure out if the raspberry pi zero is able to wake from a turned-off/stand-by state via wifi.

Also, can Anon give me random ideas/suggestions?
