This page documents features from more engineering point of view. For a more user-centric point of view, see Features.

Major Balthazar parts are:

Power Controller and battery

These supply power to the rest of the system, particularly the System on a Module, USB Hub and Display subsytem. It also manages battery.

It should be capable enough to run some USB connected hardware.

See more: Power Supply

System on a Module (SoM)

This is the main system board, the computer. Boards from different makers should be supported.

Minimum of ports is required for wider compaitibility. These are: Power, USB and HDMI.

See more: System on a Module

I/O USB hub

IO-board basically means connectivity with peripheral devices. These can be seen as on-board and out-board. On-board devices include: keyboard + trackpad, webcam and optional audio-card. USB is the usual solution for this.

For more see our I/O USB page.

Display Controller and a screen panel

Provides interface to display panel by HDMI

Case

Initial casing is meant to be made of a recyclable vegetable oil based plastic. Also the idea of a modular design gave us even more sustainable materials to look at - pressed used clothes in resin, cans recycled pressed aluminium and even resin-ed wood saw.

Here are elements we have been working with so far and slowly shaping the final design and a certain materials together.

On our Github page you can look into the .stl files too.

Chronological pictures and a phases of the development:

Keyboard and Touch-pad

See more: Keyboard

Software

Software depends on a System on a Module used.

-Internal usb devices can be switched of manually. This helps with the privacy – the microphone and webcam. For external usb devices disabling the usb power line is the same as unplugging the usb device. The condom approach with disabling the data lines is a bit better, but solves things mostly with usb plugging into public charging stations. The TPS2540 solution above is usb charging current negotiator – with no datalines connected. A dedicated (micro-usb) charging port solves this problem. The already developed Balthazar PSU-charger has this option.
+IO-board basically means connectivity with peripheral devices. These can be seen as on-board and out-board. On-board devices include: keyboard + trackpad, webcam and optional audio-card. USB is the usual solution for this.
-The job of preventing uncontrolled usb traffic from the external peripheral device which runs its own software system is problematic and should probably be done on the level of usb driver.
