Description

Does your phone battery get completely drained after a day of streaming media while you are working on a project?
This is based around a Khadas VIM 4 sbc mainly due to the compact nature of it and the extension board that supports an m.2 slot.

Details

This is Project Khosmic.

An open source media computer. I designed it to be an updated portable media player but in the process overbuilt it into a portable linux computer. It uses bluetooth to transmit the audio to either headphones, speakers, or your vehicle's audio system using audio codec.

It can be connected to a full size display with a full size hdmi and use the folding bluetooth keyboard to do almost any on-the-go linux computer needs.

Hardware specs:
- Khadas Vim4 2.2 Ghz Quad-core SBC
- Heatsink + Fan - Khadas
- Ts050 5" Touch Screen - Khadas
- New M2X Extension Board - Khadas
- PiSugar 3 Battery Power Module
- 4000 mAh battery
- Case designed using @OnshapePTC
- Battery life ~ 2 - 3 hrs

Software specs:
- Ubuntu 22.04 - Khadas
- Linux Kernel 5.4 - Khadas
- Gnome 44 w/ Gnome Extensions
- Elisa Music Player - Flatpak
- Syncthing

Syncthing syncs my whole personal music library to the device when it is on my home network. When any new media is added to the server it is automatically added the next time that the device is powered on and connected to my home wifi.

The case prints were sponsored by PCBway. They look way better than my prototype fdm prints from my prusa. They kindly reached out and offered pcb services sponsorship but that's outside of my wheelhouse. They then said they could also do 3d prints.

They turned out beautiful and we prices well enough to get more final designs printed with them without the sponsorship.

This is really great! May i ask why you did not include the HDMI input port on the rear of the board next to the GPIO?

Are you sure? yes | no
