===[http://metalab.at/wiki/OpenSource_CNC CNC Mill - Migration to EMC2]===
 
 
The CNC mill was initially operated using WinPCNC which turned out to be limited, error-prone and confusing.
 
* Researched alternatives and decided EMC2 to be the best candidate (open source, feature-rich and stable).
 
* Extracted physical parameters from the CNC and configured EMC2.
 
* Created a custom Ubuntu live CD for evaluation.
 
'''Status''': evaluated

===[[Ctrl-Cut]]===
 
 
The Metalab Laser Cutter (Epilog Legend 36Ext) is shipped with a windows-only
 
driver which needs to be operated from Corel Draw. In addition job optimization
 
is insufficently implemented and might even lead to undesired results.
 
 
* Reverse engineered the PCL based job format
 
* Implemented cups backend
 
* Wrote a postscript printer description
 
* Implemented optimization algorithms avoiding problematic cutting order and reducing job duration.

In the course of Metalab's participation in the Nokia App Forum i explored the
 
N900 device. The recommended development environment, a VM image provided by
 
the Maemo project turned out to be unready and undocumented.
 
 
* identified problems and figured intentions
 
* upgraded, cleaned up and fixed it
 
 
'''Status''': In progress/stalled - basically working though qemu's limited support for ARMel still prevents
 
productiv use

JNBD - A transparent compressed network block device daemon
 
 
JNBD is a NBD daemon implementation in java. But instead of serving an actual block device it transparently compresses blocks into files. Its primary use is to serve a read/write compressed storage device in a platform independent manner (on the server side!) over a network. Any filesystem can be setup on a jnbd instance without the need for the actual filesystem to support RW compression.
 
 
'''Status''': Beta
