"Physical" notifications with Raspberry Pi and addressable LEDs
a project by dannysauer
Updated almost 3 years ago. 3 hacker ♥️. 1 follower.

I'd like a way to have a device on my desk which lights up to indicate that I have something I should be paying attention to. Initially, I'd like this to be for Office365 calendar events and GitHub mentions, but ideally it should support arbitrary messages. The plan is to assign specific colors (ideally "patterns" consisting of a sequence of colors and time) to specific message types.

I have a handful of raspberry Pi Zeroes, a couple of OLEDs, a strand of individually-addressable RGB LEDs, a power supply, and some misc electronics (like the 3.3-5v logic level shifter necessary for the 5v LED strand). I'm thinking Python is probably the way to go for the software. I'm hoping OpenSUSE actually works on the Pi zero. :D If not, there's an ESP32 with a built-in display and a few Pi 3s laying around barely used, maybe one of them will work.

Either way, this should deliver a how-to (perhaps an instructable?) using all open source software.

      There is actually a PiHat with LED Matrix display that you can address specific LEDs or just scroll text. You can try the emulator here: https://trinket.io/sense-hat

      I almost ordered one of those. But I want a big ol' display that gets my attention. :D So, I ended up with https://www.adafruit.com/product/3346 instead. It provides a few easy pickup points for several GPIOs, and also allows the potential of making noises to accompany the lights. :D

    Symbol Relations by hli

    Description

    There are tools to build function call graphs based on parsing source code, for example, cscope.

    This project aims to achieve a similar goal by directly parsing the disasembly (i.e. objdump) of a compiled binary. The assembly code is what the CPU sees, therefore more "direct". This may be useful in certain scenarios, such as gdb/crash debugging.

    Detailed description and Demos can be found in the README file:

    Supports x86 for now (because my customers only use x86 machines), but support for other architectures can be added easily.

    Tested with python3.6

    Goals

    Any comments are welcome.

    Enhance UV openQA helper script by mdonis

    Description

    A couple months ago an UV openQA helper script was created to help/automate the searching phase inside openQA for a given MU to test. The script searches inside all our openQA job groups (qam-sle) related with a given MU and generates an output suitable to add (copy & paste) inside the update log.

    This is still a WIP and could use some enhancements.

    Goals

    • Move script from bash to python: this would be useful in case we want to include this into MTUI in the future. The script will be separate from MTUI for now. The idea is to have this as a CLI tool using the click library or something similar.
    • Add option to look for jobs in other sections inside aggregated updates: right now, when looking for regression tests under aggregated updates for a given MU, the script only looks inside the Core MU job group. This is where most of the regression tests we need are located, but some MUs have their regression tests under the YaST/Containers/Security MU job groups. We should keep the Core MU group as a default, but add an option to be able to look into other job groups under aggregated updates.
    • Remove the -a option: this option is used to indicate the update ID and is mandatory right now. This is a bit weird and goes against posix stardards. It was developed this way in order to avoid using positional parameters. This problem should be fixed if we move the script to python.

    Some other ideas to consider:

    • Look into the QAM dashboard API. This has more info on each MU, could use this to link general openQA build results, whether the related RR is approved or not, etc
    • Make it easier to see if there's regression tests for a package in an openQA test build. Check if there's a possibility to search for tests that have the package name in them inside each testsuite.
    • Unit testing?

    More ideas TBD

    Small healthcheck tool for Longhorn by mbrookhuis

    Project Description

    We have often problems (e.g. pods not starting) that are related to PVCs not running, cluster (nodes) not all up or deployments not running or completely running. This all prevents administration activities. Having something that can regular be run to validate the status of the cluster would be helpful, and not as of today do a lot of manual tasks.

    As addition (read enough time), we could add changing reservation, adding new disks, etc. --> This didn't made it. But the scripts can easily be adopted.

    This tool would decrease troubleshooting time, giving admins rights to the rancher GUI and could be used in automation.

    Goal for this Hackweek

    At the end we should have a small python tool that is doing a (very) basic health check on nodes, deployments and PVCs. First attempt was to make it in golang, but that was taking to much time.

    Overview

    This tool will run a simple healthcheck on a kubernetes cluster. It will perform the following actions:

    • node check: This will check all nodes, and display the status and the k3s version. If the status of the nodes is not "Ready" (this should be only reported), the cluster will be reported as having problems

    • deployment check: This check will list all deployments, and display the number of expected replicas and the used replica. If there are unused replicas this will be displayed. The cluster will be reported as having problems.

    • pvc check: This check will list of all pvc's, and display the status and the robustness. If the robustness is not "Healthy", the cluster will be reported as having problems.

    If there is a problem registered in the checks, there will be a warning that the cluster is not healthy and the program will exit with 1.

    The script has 1 mandatory parameter and that is the kubeconf of the cluster or of a node off the cluster.

    The code is writen for Python 3.11, but will also work on 3.6 (the default with SLES15.x). There is a venv present that will contain all needed packages. Also, the script can be run on the cluster itself or any other linux server.

    Installation

    To install this project, perform the following steps:

    • Create the directory /opt/k8s-check

    mkdir /opt/k8s-check

    • Copy all the file to this directory and make the following changes:

    chmod +x k8s-check.py

    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

    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

    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
