TechNIK's Cyberdeck

Description

Unfortunately, I didn't find out about the Cyberdeck Contest until July 10th, but I started drawing the case right away. Since I've been thinking about this thing for months, I've fortunately already got almost all the hardware together.

The Cyberdeck housing is designed in such a way that all components are screwed to the housing from the inside with sufficient space reserves. This means that holders for components can be changed later, and also the IO panels are both very easy to adapt and replace.

Due to the compact design, I decided to use a trackball instead of a mini trackpad, since I also want to remain flexible with the SBC, the trackpad is connected to the SBC via USB. This required a Arduino PRO micro which also takes the controller function for the side wheel.

It's my first project with fusion 360.

Details

Special features

side wheel with button for cursor keys and enter (useful in the terminal)
very easily customizable IO and back panel (because I'm someone whose projects are never really finished)
two wifi adapters (USB and Raspberry builtin)
two bluetooth adapters (USB and Raspberry builtin)
zigbee adapter (to debug zigbee networks)
internal SD or microSD memory
three external usb ports
external SD and microSDcard reader
external 5 gpio connectors, 5V, 3.3V, ground (so that raspberry tinkering can be tested quickly with a breadboard)
can be used as a full desktop

Does it run DOOM without throttling?
Nik Reitmann • 08/16/2023 at 18:28 • 0 comments

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
Perfect the brightness of the LEDs
Nik Reitmann • 08/11/2023 at 15:29 • 0 comments

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.
orange is the ACT LED of the raspberry and red is POWER (just like the LEDs on the Raspberry pi board)
Installing OS, configure ACT LED and Powerbutton
Nik Reitmann • 08/10/2023 at 14:16 • 0 comments

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...

Power LED now works correctly

cool-retro-term (is the name of the apt package) ;-)

The most important thing I have to configure with a new OS is the display

Code the "peripherals Arduino"
Nik Reitmann • 08/02/2023 at 21:07 • 0 comments

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:

https://github.com/LSChyi/blackberry-mini-trackball

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.
prime: all good
Too much color because it didn't cover. Pretty sure my fault too, I'm just bad at painting.

so sand again (this "heavily used" look would look cool too)
All parts printed and the visibile parts sanded

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.

Post processing

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.

Ok this is beyond awesome. I am going to set one up myself when I get done with my job.

Are you sure? yes | no

Hi, amazing work, I love it. I'm going to have a go and building one. I may have missed it in your description, but what is the purpose of the tp-link device, is the PI's own wifi not sufficient or is it to minimise RF noise near the amplifier?

Are you sure? yes | no

michael.meincke wrote 11/15/2023 at 12:34

Hi Nik. Thanks for the great design! Just (nearly) finished building it myself. The only problem I have is with the audio. I used a small PAM8403 based amplifier, which causes extreme distortion. you can literally hear the Pi and the Wifi working ;-) What kind of amplifier did you use? I was not able to find anything using the description here in the componets list...

Are you sure? yes | no

Nik Reitmann wrote 11/15/2023 at 13:30

Hi Michael, cool if you get acoustic feedback for the components, that could also be a feature of a cyberdeck ;-).

I think the cables should be better insulated, or you can use an amplifier with a jack or cinch audio connection (then you can use a pre-soldered and well-insulated audio cable). The same amplifier but with audio jack connection as stated in the parts would be:

PS: I would be happy to see a photo of your build :-) (maybe on printables: https://www.printables.com/model/551922-techniks-cyberdeck)

Are you sure? yes | no

Hey Nik, thanks for the fast feedback. Yeah, it’s not a bug, it’s a feature :-)

I read somewhere that class D amplifiers like the 8403 are very prone to noise - they amplify well, but everything…

I will check with a different one and will use a shielded cable.

I will also post photos soon

Are you sure? yes | no

Kudos on the overall design and feel of the deck. To me, it looks like a comfy and hyper-useful tool for thinking and also for playing.

Really appreciate the time and effort that went into this. Very well designed and put together. Will definitely be printing my own after I order the components.

The beauty of the case is amazing, which makes it hard to believe that it was printed with a 3D printer. I think it was hard to make this one.

Are you sure? yes | no

Nik Reitmann wrote 08/30/2023 at 16:20

Thank you. With enough sanding work, every 3D print becomes a beauty :-)

Nik, this is looking incredible! Rooting for you on the contest! Amazing work in such a short time!

Thank you. Unfortunately, I didn't have enough time either, otherwise I would have concentrated even more on the software part. Your deck also looks incredibly good, there are a lot of nice decks in the contest.

Are you sure? yes | no

Thank you very much, it would also be a pity for your cyberdeck if it broke during the apocalypse :-P Really a very nice and cyberpunky build
