I have absolutely no electronics knowledge at all, so really I'm asking if this is possible within a reasonable budget. I want to build a hand held device with a screen (mobile phone size) that can display simple text files, has a usb port, so I can connect a pen drive to store the text files, and a 9 pin RS232 port to transfer the files with certain protocols.
Firstly is this possible to build myself? Do I need some sort of processor or can I use flash memory to control the configuration settings? Idea's on costs? Thanks for reading.
