Another pi400 cyberdeck - NERV Inspired

Simplest possible cyberdeck assembly I could manage while trying to replicate a neon genesis evangelion terminal

Idea for this originated from a post on r/cyberdeck over a year ago. I really like the utility in the device shown there.

No built-in mouse here. Ran out of space after cable routing and installing the 10kmah battery, though I had wanted a touchpad to come out of a drawer that'd slide in and out from under the bottom of the keyboard. I hate how most laptops put the pad directly under your wrists.

Like most of these types of projects, I figured the easiest starting point would be a raspberry pi400. Then I found a screen in a perfect form-factor.  Throwing those in a shell should be no problem.

Form factor comes from pictures listed on reddit over a year ago:

I wanted access to all the pi400 ports and GPIO.  A hacker deck is all but worthless if you can't actually interface with data pins on other devices.  The biggest challenge with this was finding clean panel mounts for the ports.  Not many places make really small cables with a focus on thinness.  I had wanted clean seams around the entire case- at least for the ports- but that wasn't possible.  Panel mount ports were the best option to screw into the shell, but the footprints on them are really large.

To go for a cleaner look, I ended up buying a separate raspberry pi keyboard in black. The same cable is used for the standard keyboard keys as the pi400 keyboard, so that was a simple swap.

Initially I just wanted the large flat brick form-factor, but the utility of the screen being able to tilt to 90° was just too nice.  I struggled trying to find ways to design this until I found a solution on thingiverse using M5 screws, nuts, and washers:

Power is also kind of a pain to manage, though the pi400 has a keyboard button combo for power. The whole thing runs off an ANKER 10k mah portable charger.  The specific model was chosen for both its capacity and the fact that it outputs the 5V 3A required by the pi400.

I was tempted to print the shell in a flourescent color, but found a glow in the dark filament at Form Futura.  You need to leave the deck in the sun for a few hours, but you don't need internal RGB when the shell itself glows in the dark.

This project could certainly use some clean-up.  The top section's USB panel mount is 2.0 - a 3.0 cable is supposed to be available soon. The secondary HDMI panel mount cable is super awkward and takes up way too much space - that will also get replaced when an alternative is found.
