So, I have this nifty little device called a raspberry pi. Its a minicomputer, (Google for more info). Well, if you've heard of it, you may know of all the cool things done with it. My question is, does anyone know how would go about powering both is, and a small display from the same power source? What hardware would I need, and how would I go about it. Thank you in advance. (In case you're wondering, I'm planning to mount it on my arm because I think that would be awesome)
