Print

Case printed in two parts, the rest can be printed in one piece. All printed with a Bambu X1C, a 0.6mm nozzle, in PETG with a layer height of 0.18mm. 

The printing time for all parts was approx. 20 hours.

IO Panels are customizable (blank panels are foundable in files in this project).
The case is also available as [full] and as [splitted] in the files.

Parts

Mostly AliExpress, see "components" in this Project.

Glued with epoxy resin and sanded with 320 grit sandpaper. Then primed several times, sanded wet with 600 grit sandpaper and painted with two coats.

You can use the pins that you want on your microcontroller, in the peripherals_firmware you have to define your choosen pins. In the code the section with the PIN definitions is marked with "START_PIN_DEFINITIONS".

Simply flash the "cyberdeck_peripherals.ino" code from the files to your HID enabled arduino.

If you want to change the direction of the knob you can swap the PINs in the code or physically swap the PINs on the Arduino

While the Arduino is still connected to the PC, you can use the serial terminal in the Arduino IDE to test whether everything is working. The terminal should output the following:

left mousebutton press

left mousebutton release

right mousebutton press

right mousebutton release

knoob rotate right

knoob rotate left

knoob pressed

The assembly is pretty self-explanatory. Provided both cable harnesses are soldered, the following sequence is recommended:

(all 3d printed parts are written in bold in the following text)

1. remove all outer keys of the keyboard, insert them into the case and position them upwards to the stop
2. keyboard_cover > case (4x M2 x 20mm)
3. Reinsert the keyboard keys
4. display > display_outer_frame
5. display_and_sbc_mount > display_outer_frame (8x M2 x 16mm)
6. screw display with display_and_sbc_mount together (8x M2.5 x 6mm)
7. connect usb and hdmi to the display
8. power_led -> display_outer_frame
9. insert display_outer_frame in case and screw together (4x M2 x 16mm)
10. insert rotary encoder and screw on with rotary_knoob_mount (2x M2 x 12mm)
11. rotary_knoob > rotary encoder
12. both mousebuttons > case
13. trackball breakout board > case
14. trackball_and_mousebutton_mount > case (7x M2.5 x 6.5mm)
15. arduino > case (with a cable tie on the holder between display and keyboard)
16. powerbutton > case
17. powerbutton_mount > case (4x 2.5 x 6.5mm)
18. speaker_grill > case
19. speakers > case
20. 3x speaker_mount > speakers (6x M2.5 x 6.5mm)
21. cooler > rasperry
22. raspberry > display_and_sbc_mount (2x screws and 4x spacers included with cooler)
23. connect the keyboard and the peripherals arduino to the raspberry via usb
24. prepare and install your IO and back panel
25. cover > case (8x M2 x 12mm)

Install your facorite raspberry OS (nothing special that might not work with some linux distros)

Power LED does not have to be done (this is at 5V), for the ACT LED the following must be entered in /boot/config.txt:

old EEPROM (< 000138c0):
dtoverlay=act_led_gpio=25

or with actual EEPROM Version (> 000138c0):
dtoverlay=act-led,gpio=25

Use the fan function from raspi-config tool, you only have to set the right PIN and the temperature treshold.

Better use actual instructions from:
