Raspberry Pi: Turn the popular single-board computer into a handheld computer with a slide-out keyboard and display
Brought to our attention by Liliputing, the MutantC_V2 builds on the MutantC_V1 that developer rahmanshaber published last year. the second version of a very special project has already been published. In short, the MutantC_V2 turns a Raspberry Pi into a handheld computer reminiscent of the Sony VAIO UX or early Android smartphones like the HTC Dream.
Incorporating a pull-out keyboard and a display, the project can utilise a Raspberry Pi Zero, Model 2, Model 3 or Model 4. According to the developer, 2.8-inch, 3.5-inch or 4-inch LCD panels can be used, which all communicate with your chosen Raspberry Pi via GPIO. Links to examples of the three display sizes can be found in the parts list of the project's GitLab page.
The MutantC_V2 also calls for an Arduino board for connecting the keyboard and two custom PCBs, the Gerber files for which rahmanshaber has provided. Additionally, you will need multiple buttons and cables, along with boards for the Raspberry Pi to work with a 18650 cell battery.
