I hear ya. One of my Raspberry Pi's sat around for a year or two. Then I got this idea to connect my sheet-fed scanner to it and scan pages directly to Dropbox. That worked nicely. My 2nd RPi I got 2 Canon Selphy Printers and setup a gmail account where I could send pictures to. The RPi picks up the images and send them to the printers in a round-robbin fashion. ... I guess what I'm saying is the sky is the limit... So how do you follow-through? The idea needs to have some practical purpose. In my case, I use both those setups regularly.
