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.

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.

openSUSE 13.2 ARM hackathon

a project by algraf

openSUSE 13.2 is taking shape on ARM, but we need to make sure we smoothen its edges to make an actual release out of it. The goal of this project is to make sure all devices we should run on actually work and that the last few packages necessary for productive use of ARM devices work properly on 13.2.

Disk operations should not stale the system

an idea by pmladek

It happens from time to time that my system is less responsible. It is usually caused by extensive disk operations, e.g. searching disk for something, moving a lot of data. A solution would be to run these problematic tasks with ionice. But I think that desktop user should not need to take care of this. Also some of the operations are even caused by system tools and normal user has problems to affect it. I wonder if we could somehow improve the desktop setting or it it would even need some hacks into the scheduler. I have just heard that this should be fined in the last kernels. But I also heard that it still does not work well, for example when copying from/to USB memory stick.

Biofeedback / Neuroscanner / Dreamanalyser

an idea by chuller

This project is based on some hack of a mind flex toy containing a so called "neurosky eeg" chip. Having a sensor connected to your skull this system can meassure several waves emitting from the brain, also called brainwaves. The Idea is to combine this system with some camera based monitoring system that will watch a test subject while sleeping and recording the corresponding brainwaves for later analysis of brainactivity and body movement. Other use cases do exist, this was the only one i could come up with that involves sleeping in the office ;)
