This page document features from a more user-centric point of view. For a more engineering point of view, see Specifications.
Basic specifications and features
Balthazar is made to run NixOS, Trisquel GNU, Guix, Debian and Ubuntu variants of 64 bit low-latency kernel for RISC-V.
In a form factor, there are some improvements and novelties in approach to a physical user interface and experience.
The main characteristics of Balthazar are 4 robust hardware switches for WiFi, camera, microphones, and speakers, SoM CPU/GPU swappable card, a removable camera module with 2 microphones array, a keyboard layout with a segmented touch-pad positioned above the keyboard with pull-out speakers. Motherboard(s) components are behind the screen and below the keyboard are batteries - one small non-removable and one big that is hot-swappable - SSD bay is also below the keyboard, as well as other peripheral connectors - GPIO, USB OTG-secure, HDMI, headphones, and mic inputs, volume knob and finally eSATA.
When the display lid is closed it engages the magnetic switch based on the "Timer Manager Module" and cuts off the power to all of the I/O modules preventing any remote "switch-on" possibility even before it suspends to RAM.
The keyboard is QUERTY with 7 LEDs illuminated and clickable 8 mm trackball positioned between G and H keys and above B key. It is based on Cherry MX low profile gaming switches
So when we say the "design is different", it actually is inspired by and extracted from IBM/Lenovo ThinkPad series, Panasonic ToughBook,a OLPC and main secure USB-dongle features based on Nitrokey concept.
Balthazar's design aims for a new usability experience.
"10 or so years ago there were no mobile phones, but we all learned how to use them." (Arjen Kamphuis in xTED speech in Delft)
Current internals layouts
Here we played with our developed boards' inner layout possibilities. While designing the housing and hinging we will update those designs and the inner concept regularly.
Components
CPU and RAM - as the development goes on BPCD is based on RISC-V and ISA architecture multi-core SoM or a System on a Module "card" that is exchangeable and upgradeble. Added to it is FPGA co-processor based on a ingenious design by Radiona - a MakerSpace from Zagreb, Croatia - ULX3S.
RISC-V architecture is understood as an ideal vehicle for the security community.
We also keep an eye on ARM Cortex - A7x iterations along the path, waiting for their development to align with our expectations which are open documentation that will enable the Open Source community to write drivers and other software.
With a maximum reasonable amount of RAM, we use the most rational clock speeds to achieve the best possible computing performance versus battery power consumption. There should be no compromise there. In any case, count on 8+ Gb RAM and some serious processing power.
GPU - ARM's MALI-4xx architecture would do great, but we also look into drivers' compatibility and openness, too.
While NVIDIA would be technically possibly the best performance choice, issues arise with a general attitude towards FOSS compatibility.
In any case we look and listen into NVIDIA and CUDA options, accelerating totally open documentation from NVIDIA's side.
Also the NVIDIA's Jetson IoT and AI platform is researched for a compatibility with RISC-V architecture, ISA and FOSS .
Storage - a SATA SSD is on board and it should be taken out very fast from a bay.
eSATA connector might help in expanding the storage possibilities.
Fanless - less movable parts means more battery time for the processing power and a passive cooling adds to the longevity of the components. Think quiet.
Boot and sleep - Secure-boot as well as a fast boot time. Nobody has and especially children do not have the patience to wait.
Ever since C64/AMIGA times computers should be able to be switched on and off fast, so using some Libreboot/Coreboot and a Clear Linux (minus Intel optimisation) concepts applied in a BPCD firmware/BIOS should do it.
BPCD suspends to RAM and goes to hibernate when battery is at 20%. Properly.
Upgradeable - RAM and a processor-board featuring SoM attachment port.
A non-glare screen - size is 13.3” 16:10 full HD resolution (200 dpi +) that provides far less strain on user's eyes.
'A non-reflective - a button drove backlight “off” monochrome mode for very low-power use in sunlight - prolongs a battery life a lot.
LED backlit - color mode with an alternate of red, green, and blue pixels.
A detachable webcam - also with a slide lens cover and a hardware switch for on/off
A volume wheel - a ceramic volume potentiometer with a “click” for the on/off functionality.
GPIO - a retractable and flexible robust flat-ribbon cable connecting General Purpose Input Output 19 pins array for connecting to all the things you want to connect it to.
Quick charging battery - Long Life Cycle Polymer 10000+ mAh that is also recyclable.
Hot-swap - a second small battery enabling main battery hot-swap.
Modular power - on-board power supply that follows full ACPI specification defaults to scalable/modular voltage for the processor and memory by the design aims at preventing the so-called side-channel attacks. ISA already specifies that no data is kept in the cache, but the remote possibility of such an attack still exists.
Waterproof keyboard - with an illuminated track-point ball, firmware includes default onboard SSH compression (ssh -C) enabled communication between keyboard's motherboard and the rest of I/O hardware - prevents key-logging and keystroke timing and guessing algorithms.
Multitouch pad - a smooth surface, flat-flush and positioned above the keyboard. It has a “Wacom”-style mode for the extended stylus or a finger draw.
It is multi-touch and gestures capable.
Casing - a tough, rugged form-factor done in a multi-color polycarbonate, or aluminum composite, and recyclable plastic with maybe added LEGO® studs here and there.
Hardware security and privacy features
Four (4) hardware off/on switches - webcam (detachable), speakers, the microphones array (detachable) and obligatory Wi-Fi.
Detachable USB gender-changer dongle - that should prevent anyone to plug in USB-anything unless it is attached and a password unlocked, also when it is taken out prevents anyone to stick USB-anything in. Basically - a bit secured USB onboard.
A few interesting extras
TEMPEST-shield internal cabling - shields from any external and internal electromagnetic radiation. Weaved and braided cable shielding above MIL-SPEC/DTL and GOST/IST standards.
A stylus - for a pad drawing, also provides enhanced entropy while generating PGP keys, easy graphic editing, poking someone, etc.
Additional adapter with an onboard:
LEGO® Power Functions - for powering and the control of actuators. .
RJ-12 LEGO® - “a shifted notch” connector for LEGO® MINDSTORMS® series of actuators and sensors,
a male D-Sub serial port (tty) and a VGA connector.
Charms
LEGO® keychain - for the USB dongle.
