Project Description

The BSEC library provides signal processing and sensor fusion for the BME680, a low-power gas, temperature, humidity and pressure sensor. This sensor communicates with the MCU using SPI or I2C to report the measurements, but lacks in-die calculation for air quality index, it just reports the gas sensor resistance.

Bosch provides a closed-source software library called BSEC to process and fusion the BME680 sensor signals. It provides several outputs called "virtual sensors", one of them being the air quality index (IAQ):

BSEC_OUTPUT_RAW_PRESSURE
BSEC_OUTPUT_RAW_TEMPERATURE
BSEC_OUTPUT_RAW_HUMIDITY
BSEC_OUTPUT_RAW_GAS
BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_TEMPERATURE
BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_HUMIDITY
BSEC_OUTPUT_IAQ
BSEC_OUTPUT_STABILIZATION_STATUS
BSEC_OUTPUT_RUN_IN_STATUS

The reason for writing python bindings for the BSEC library is to integrate the BME680 air quality measurements to HomeAssistant running in a RaspberryPi.

Goal for this Hackweek

  • Write the Python bindings for the BSEC library
  • HomeAssistant integration

      A short comment:

      These two repositories make a link between the BSEC library and some kind of publishing. The library is instantiated via a C program, and the output is caputured/parsed by a python wrapper.

      • https://github.com/rstoermer/bsecbme680python/
      • https://github.com/timothybrown/BSEC-Conduit

      These indicate there is some demand out there :)

    Capyboard, ESP32 Development Board for Education by emiler

    Description

    Capyboard 3D

    Capyboard is an ESP32 development board built to accept individual custom-made modules. The board is created primarily for use in education, where you want to focus on embedded programming instead of spending time with connecting cables and parts on a breadboard, as you would with Arduino and other such devices. The board is not limited only to education and it can be used to build, for instance, a very powerful internal meteo-station and so on.

    I already have one initial prototype ready and tested. The next iteration addresses several issues the first prototype had. I am planning on finishing up the mainboard and one of the modules this week.

    This project is also a part of my master's thesis.

    Goals

    • Finish testing of a new prototype
    • Publish source files
    • Documentation completion
    • Finish writing thesis

    Build a split keyboard from scratch by mpagot

    Description

    I'm getting older... this summer I experienced an annoying and persistent tingling in one hand and arm. That was the initial motivation to get more interested in ergonomic work gadgets, and from that to split keyboards. And that was the entrance in a rabbit hole.

    Which keyboard I like to create:

    • Split keyboard for ergonomic (I'm not primary interested in having it portable)
    • I have big hands: I like it to fit as much as possible my hands measures
    • Columnar stagger keys position
    • Not too few keys (at the moment I'm at 24 + 24)
    • One row thumb cluster
    • No wireless, not to have batteries and for security reason
    • CherryMX, or generally speaking no low profile/corne choc
    • Hot swap Socket switches

    Goals

    • Create PCB design for a split keyboard
    • Get it produced
    • Mount it
    • Evaluate FWs

    SUSE Prague claw machine by anstalker

    Project Description

    The idea is to build a claw machine similar to e.g. this one:

    example image

    Why? Well, it could be a lot of fun!

    But also it's a great way to dispense SUSE and openSUSE merch like little Geekos at events like conferences, career fairs and open house events.

    Goal for this Hackweek

    Build an arcade claw machine.

    We're looking for handy/crafty people in the Prague office:

    • woodworking XP or equipment
    • arduino/raspi embedded programming knowledge
    • Anthony can find a budget for going to GM and buying servos and such ;)


    Framework laptop integration by nkrapp

    Project Description

    Although openSUSE does run on the Framework laptops out-of-the-box, there is still room to improve the experience. The ultimate goal is to get openSUSE on the list of community supported distros

    Goal for this Hackweek

    The goal this year is to at least package all of the soft- and firmware for accessories like the embedded controller, Framework 16 inputmodule and other tools. I already made some progress by packaging the inputmodule control software, but the firmware is still missing

    Resources

    As I only have a Framework laptop 16 and not a 13 I'm looking for people with hardware that can help me test

    Progress:

    Update 1:

    The project lives under my home for now until I can get an independent project on OBS: Framework Laptop project

    Also, the first package is already done, it's the cli for the led-matrix spacer module on the Framework Laptop 16. I am also testing this myself, but any feedback or questions are welcome.

    You can test the package on the Framework 16 by adding this repo and installing the package inputmodule-control

    Update 2:

    I finished packaging the python cli/gui for the inputmodule. It is using a bit of a hack because one of the dependencies (PySimpleGUI) recently switched to a noncommercial license so I cannot ship it. But now you can actually play the games on the led-matrix (the rust package doesn't include controls for the games). I'm also working on the Framework system tools now, which should be more interesting for Framework 13 users.

    You can test the package on the Framework 16 by installing python311-framework16_inputmodule and then running "ledmatrixctl" from the command line.

    Update 3:

    I packaged the framework_tool, a general application for interacting with the system. You can find it some detailed information what it can do here. On my system everything related to the embedded controller functionality doesn't work though, so some help testing and debugging would be appreciated.

    Update 4:

    Today I finished the qmk interface, which gives you a cli (and gui) to configure your Framework 16 keyboard. Sadly the Python gui is broken upstream, but I added the qmk_hid package with the cli and from my testing it works well.

    Final Update:

    All the interesting programs are now done, I decided to exclude the firmware for now since upstream also recommends using fwupd to update it. I will hack on more things related to the Framework Laptops in the future so if there are any ideas to improve the experience (or any bugs to report) feel free to message me about it.

    As a final summary/help for everyone using a Framework Laptop who wants to use this software:

    The source code for all packages can be found in repositories in the Framework organization on Github

    All software can be installed from this repo (Tumbleweed)

    The available packages are:

    • framework-inputmodule-control (FW16) - play with the inputmodules on your Framework 16 (b1-display, led-matrix, c1-minimal)

    • python-framework16_inputmodule (FW16) - same as inputmodule-control but is needed if you want to play and crontrol the built-in games in the led-matrix (call with ledmatrixctl or ledmatrixgui)

    • framework_tool (FW13 and FW 16) - use to see and configure general things on your framework system. Commands using the embedded controller might not work, it looks like there are some problems with the kernel module used by the EC. Fixing this is out of scope for this hackweek but I am working on it

    • qmk_hid (FW16) - a cli to configure the FW16 qmk keyboard. Sadly the gui for this is broken upstream so only the cli is usable for now
