Support for the SMBus ARP protocol

a project by jdelvare

The SMBus standard specifies an address resolution protocol (SMBus ARP.) It has two key features : * Handle I2C slave address collisions. If two SMBus slaves would use the same I2C address, ARP lets one of them pick a different address to avoid the address collision.

ALSA Pure Digital Power Amplifier

a project by duwe

Building on top of <a href="http://rdimitrov.twistedsanity.net/blog/show.php?entry=Microcontroller%20Class%20D%20Amplifier,%20Rev2&quot;&gt;Rouslan Dimitrov's Microcontroller Class D Amplifier</a>, I developed the idea to feed the power amplifier with PCM data directly. Rouslan does some dithering and noise shaping, but I'm convinced that proper interpolation would sound better. The ATtiny is too slow to do even cubic interpolation so I'll move that into the host.

Make Intel baytrail based device(s) work better with openSUSE

a project by mkubecek

Recently I became a (not very proud) owner of Acer Aspire Switch 10E, a small notebook/tablet convertible based on Intel baytrail platform. Replacing preinstalled (32-bit!) Windows 8.1 with (64-bit) openSUSE proved more challenging than expected, mostly because the device is haunted by a 32-bit UEFI so that it took me a week to make it boot without an external USB flash disk. Even today, a lot of issues persist. As I do not want to waste a (partially) good hardware, I would like to make it as usable as possible. This is much less selfish than it sounds as there are many other devices based on Intel baytrail platform so that the effort is going to help their owners as well (if successful, that is).

Make Tumbleweed work on the GPD Win

a project by aplazas

The GPD Win is a Nintendo 3DS XL sized PC featuring a keyboard and gaming controls. Having openSUSE working on it would be great, unfortunately Tumbleweed doesn't work at all on it and Leap 42.2 is lacking many important features. A GPD Win runnning Leap 42.2

work on sunxi a64 cpufreq driver (for teres-1, pine64)

an idea by mbrugger

With the teres-1 [1] laptop we have a first arm64 device we could use as end-users. Much work to run mainline kernel + u-boot was done already. But power consumption of the laptop is not optimal (~2 hours of battery life time). The idea is to support cpufreq for the A64 SoC upstream, which would enable the teres-1, pine64 and pinebook to run more power efficient. up to now it seems nobody is working on the driver [2].

"Physical" notifications with Raspberry Pi and addressable LEDs

a project by dannysauer

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.

Python bindings for Bosch Sensortec Environmental Cluster (BSEC) library

an idea by scabrero

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.

Remote alarm system using RaspberryPi pico for box room

a project by scabrero

Project Description

I have a box room in the garage where I store all my precious mountain gear. This project aims to create a remote alarm system using a pair of MCUs (a RaspberryPi pico and a ESP8266) connected by a LoRa PtP link.

Create a DRM driver for Matrox desktop cards

an invention by tdz

(was: Create a DRM driver for Matrox G200) Even after 20 years, the Matrox G200 series is still an excellent 2d graphics card. Unfortunately, there's only an fbdev driver and a user-space driver. Both are obsolete, as modern Linux uses the DRM framework for managing graphics cards. There already is a DRM driver for the G200 server series. This driver is under-maintained and doesn't work with desktop chips.
