With many Samsung zFlip phones hitting the unfortunate fate of a broken folding screen, I took it as an opportunity to build my own silly phone. Taking only the minimum parts required for the phone to function, I redesigned the entire enclosure for a *slightly* different CNC machined aluminum one. I split the two halves, added a four bar linkage for a flip out action, and of course; I added a BlackBerry keyboard to the internals. With an Arduino pro micro inside emulating a USB keyboard, this wacky smartphone now has a permanent physical keyboard, you can flip out on demand. A truly modern take on a flip phone in my opinion.

The new enclosure is CNC machined, bead blasted and anodized in brown and green by PCBWay. The PCB is a 0.1mm flex.

Here is the full video documenting how it was made:

This is a one off project which has its own issues and is by no means designed for larger scale production, thus I don't feel comfortable sharing the design files, as they are not ready to assemble off the shelf, My apologies.
