TechNIK's Cyberdeck

Whether DOOM runs on a Raspberry Pi 4 is almost a boring question, but it is enough to show how well the cooling and the power supply for the devices in the case are.

As can be seen in the demo videos, Raspbian does not run as efficiently as kali linux. I will probably use kali linux despite the many packages that need to be updated.

Taskbar TOP: Kali Linux
Taskbar BOTTOM: Raspbian

At the beginning I took two 500ohm resistors, the red LED was much too bright and the orange hardly recognizable. Now the orange LED has a series resistance of 50 Ω and the red 1 kΩ.

Since I have external access to the raspberry microSD, I don't have to make a final decision on an OS.  I am currently testing whether raspbian (32bit) meets all my requirements.  I have already created a kali linux microSD and adapted the OS installation to the cyberdeck, kali linux only has the disadvantage for me that it contains a lot of packages which all have to be updated...

I noticed that it's not that easy to write the firmware for the trackball myself, my version was pretty sticky, but it worked. However, that was enough for me to understand the function. Then I have to look for a clever library on the internet, but unfortunately I didn't find any library, but the following brilliant demo code:

The trackball works super smooth now. The rotary encoder with the button and the two mouse buttons were then written fairly quickly.

I will upload the arduino code, all STL's of the case, bash scripts etc. here at the end of the project (hopefully before the cyberdeck contest deadline).

When coloring the case, everything that could go wrong went wrong.  I bought a weird PU spray that splattered so particles and didn't cover at all (not even the gray primer).  So sand and prime again.
