The problem with DIYing things with a Pi, I find, is that you inevitably end up with a fragile nest of wires and not a device you can rely on not to have been cannibalized (probably by oneself) or unplugged or disassembled to make room for other stuff. Not conducive to something like a bombproof note taking device that's always on standby- and good luck if you want it to be portable or even luggable.
