I'm in the process of designing a cosplay phone based on Okabe Rintarou's flip-phone from the visual novel Steins;Gate, and I want the end result to be both aesthetically accurate as well as actually functioning.What I have so far:I've decided to base the phone on a Raspberry Pi Zero W, as it's just about the right sizeThe phone should, in total, be able to do the following:Flip (in other words, it needs a hinge separating the keyboard from the screen)Manage contacts (phone number, email address and name)Make phone calls (using a SIM, was thinking of using something like this)Send text messages (SMS)Send emailThe outer casing would either be 3D-printed or moulded from fiberglass. If the former, I'd make the 3D model myself. However, what concerns me is the fact that it would be in two parts (screen casing and keyboard/SoC casing), and I don't really have experience on this.Planned nice-to-haves:Open a simple browser (probably using a modified Firefox or Opera, possibly Min)A functioning camera (accessible when sending mail)What I need help with:I don't really know what I need besides the SoC board (Pi Zero W), GSM shield, microphone, speaker, screen and battery.Software won't be a problem (I could do it with my eyes closed), but how should I approach creating the internal frame that holds the thing in one piece?Are there any smaller boards, or similiar, that would enable GSM connections with the SIM? I couldn't find any, but perhaps someone else knows?What should I do for the keyboard? Should I solder the board from scratch, or...? And what about the buttons themselves?Here's a couple images of the phone in question, and approximate measurements of the space for the internals:Phone from the frontPhone from an angle (pic is of a one-piece replica with no hinge)Thanks in advance. via /r/DIY https://ift.tt/2zTGM8h
