Automate Victron Cerbo GX scheduled charge configuration based on Redflow ZCell maintenance cycle timing

an invention by tserong

Project Description

At my home we have solar PV hooked up to Victron inverter/chargers and a Redflow ZCell battery for energy storage. The setup is described in detail on my blog. By their nature, ZCell flow batteries needs to undergo a maintenance cycle at least every three days, where they are discharged completely for a few hours. Having only one battery, this means we can't use the "minimum state of charge" feature of the Victron kit to always keep some charge in the battery in case of outages, because doing so conflicts with the ZCell maintenance cycles. This isn't a problem if you have more than one ZCell, because the maintenance cycles interleave in that case, but so far we only have one of these things. If I want to keep charge in the battery for emergency purposes on non-maintenance days, I can do that by configuring scheduled charge settings manually on the Victron Cerbo GX console, but then I have to remember to turn those things back off (or otherwise adjust the settings) for the next maintenance day. For this hack week, I'm going to see if I can automate that piece somehow.

Project Description

When I boot my laptop, I am prompted for 3 passwords: the password for full disk encryption (FDE), the password to login as my user and the password for my password manager. I want to explore a solution to have only to enter a single password to unlock all three.

Bootstrap Maven in OBS

a project by a_faerber

Apache Maven is a build tool used by many Java projects, which is incompatible with OBS in that it tries to download binary dependencies from the Internet. Several people have in the past years tried to somehow bootstrap Maven and failed. My new proposed approach is a Maven, patched to obtain packages from a filesystem location, and packages with .jar based -bootstrap.spec variant plus source-based build for properly modeling dependencies in OBS. Unlike the SUSE Manager team's work I am trying to rebuild those .jars from sources. Where necessary I am patching dependency versions to the latest sources/jars packaged.

Speed up installation

a project by jreidinger

Installation time is important as shorter installation allows everyone to safe resources and their time. It also can make better impression when starting with openSUSE and SUSE. And last but not least as we more frequently use openQA, so we do hundreds of installation every week, it even smaller improvement can in the end help SUSE to safe resources and be more green.

New office decoration

a project by mdeniz

As we have grown in our remote and non official office at Gran Canaria we had to rent another space. This new office is almost empty and we need a little bit of love to improve the sensation of relax and commodity while we do what we love most. The main target of this project is to kickstart the decoration process, creating a minimum plan of what we want to achieve and step the first steps :smile:

Fix order of use co-operation between vlc and camsource applications

a project by dmair

Using the camsource and vlc packages as an example. If camsource is configured to use a given dev/video[n] device with a choice of resolution in the width and height fields of a camsource conf file then if camsource is the first application to access the device captured images are as-expected. However, if an application like vlc is used for the same device (and exited) before starting camsource (e.g. to check the view from the camera before starting camsource) and if the camera supports higher resolutions than used in the camsource configuration what occurs is that camsource will not setup the camera to use the configured resolution and has a broken view of the camera output based on the vlc chosen resolution chopped to the camsource configuration. For example, with camsource configuration set to use 640x480 on a camera that supports 720x480 and vlc is used and exited before camsource is started then the captured camsource images contain two non-continuous partial image blocks with a horizontal border dividing them. I assume either vlc fails to fully reset the device configuration when exiting or camsource fails to initialize the device "from scratch" when starting. The two applications use different video device APIs but the setup and cleanup for the camera in each case is a very limited part of the application's functionality.

Create evdev Event Recorder & Playback Driver

a project by eeich

The user space interface of evdev is pretty generic. All hardware abstraction is done in the kernel driver, device properties are mapped to a set of generic properties. The properties can be queried thru a generic interface only very few parameters are set from user space. In user space the evdev API is used by Xorg's evdev driver and libinput.

Lioncast RGB Keyboard user software, protocol reverse engineering

a project by rsimai

I recently bought a Lioncast LK200 RGB keyboard which is a nice piece of hardware and has exactly the look and feel I want. All basic functions work well under Linux. Unfortunately the manufacturer only provides user software to upload/download profiles and control the LEDs for Windows. The device can be configured and operates autonomously from any OS but color setup is a PITA and it's very easy to factory-reset, and lose all config. I approached them but Lioncast seems neither interested to support native Linux nor to provide protocol specs so one can implement it. I thought to take this as an example to learn about reading and reverse-engineering USB device software.

Create a custom elemental image that bundles k3s

Project Description

With the discontinuation of k3os, there is no minimal Linux available that bundles the OS with k3s, but with Elemental one can create custom images that can be extended. The community has been asking for this, but we don't have an immediate need for enterprise customers, so it hasn't been prioritized.

Solar water heating control panel using ESP32

a project by alarrosa

Project Description

I have in my house a solar panel to heat water that is controlled by a "dummy" control panel from which I can see the current temperature of the water in the solar panel and the water in the tank. There's a pump that moves water from the tank into the solar panel and back into the tank in order to heat it when the temperature of the solar panel is x degrees higher than the temperature in the water tank. There's also a resistance in the water tank that can be turned on to heat the water when there's no sunlight.
