I have this old portable dvd player laying around,it don't play disks anymore either, and i almost tossed it out millons of times. (it's a polaroid dpa-07046Q portable dvd player ). im wondering if i should take out the main board a put the raspberry pi in or should i do something else? i don't have the battery so im just gonna use a usb power supply if i just use the raspberry pi board. I REALLY kinda want to do this so may you help me with my questions?
