* Lars-Peter Clausen and Michael Walle improved Linux 3.0 on Milkymist One. [https://github.com/milkymist/linux-milkymist/commits/master]
* Lars-Peter Clausen ported an OpenWrt userland to Milkymist One, with static linking and uClibc. [https://github.com/milkymist/openwrt-milkymist/commits/master]
* Xiangfu Liu setup daily builds of OpenWrt for Milkymist One. [http://fidelio.qi-hardware.com/~xiangfu/compile-log/]
* Lattice Semiconductor released version 3.8 of the Mico32 core, which among small fixes comes with a major cleanup of the licensing header at the top of every source file. Earlier licensing headers were hard to understand and got some people to doubt the openess of the core. The new headers make the Mico32 core indisputably open source and GPL compatible.

* Christopher Adams designed a new Milkymist logo and selected the free [http://www.theleagueofmoveabletype.com/fonts/12-orbitron Orbitron font] for logo and branding. roh from [http://raumfahrtagentur.org/ Raumfahrtagentur] engraved a mirror version of the new logo on the inside of the top acrylic for the upcoming RC3 run.

* Wolfson Microelectronics' WM9707 audio codec helped reduce audio noise on the Milkymist One RC3 video synthesizer by 90%, from about 500 mV to about 50 mV. Earlier runs used a National Semiconductor LM4550B codec. [http://en.qi-hardware.com/wiki/Milkymist_One_run_3_schedule#Audio_Noise]
* Cristian Paul ported the [http://www.dynamics.co.nz/gpsreceiver Namuru GPS correlator] to the Milkymist SoC (thanks to Fabrizio Tapper and Peter Mumford for their support). This core will allow speedup of the correlation process for getting a fix and tracking GPS satellites. Work continues on the OpenSourceGPS receiver which will provide the high level software interface to process the navigation data tracked by Namuru.

* David Kühling helped port the SoftGNSS matlab code to GNU Octave. This will allow offline analysis of raw data for a variety of GPS front-ends. [https://github.com/kristianpaul/SoftGNSS SoftGNSS repo]
* Jon Phillips gave a talk about Milkymist One at FISL 12 in Porto Alegre, Brazil ([[#Jon.27s_slide_deck_on_Milkymist_One|slides of talk below]]). [http://en.wikipedia.org/wiki/FISL] [http://softwarelivre.org/fisl12]

:[[File:Ben-wpan-range.pdf|500px|thumb|none|Range of ben-wpan boards measured at Werner's apartment in Buenos Aires (dimensions in cm).]]

===Copyleft Hardware Explained===
* Werner Almesberger published a two part comparison of Free scripted CAD tools - [http://projects.qi-hardware.com/index.php/p/wernermisc/source/tree/master/cad/test1/README Part 1], [http://projects.qi-hardware.com/index.php/p/wernermisc/source/tree/master/cad/test2/README Part2].

* The names of component packages are often confusing and vary among manufacturers. This is Werner's first step (for small logic gates) towards a [http://lists.en.qi-hardware.com/pipermail/discussion/2011-July/008483.html packageology].
* Some data sheets don't contain all the information necessary to make Copyleft Hardware. Here is Werner's [http://lists.en.qi-hardware.com/pipermail/discussion/2011-July/008487.html anatomy of a datasheet].

===NanoNote===
* Jadon Dutra made two nice Ben NanoNote tutorial videos. [http://lists.en.qi-hardware.com/pipermail/discussion/2011-June/008312.html]

===OpenLase===
* David from Tuxbrain [http://lists.en.qi-hardware.com/pipermail/discussion/2011-July/008466.html found out] about OpenLase, an open laser projector started by Hector Martin "marcan". We are learning about [http://en.wikipedia.org/wiki/Laser lasers], [http://en.wikipedia.org/wiki/Galvanometer galvanometers], [http://en.wikipedia.org/wiki/Dichroism dichroic mirrors] and more now and are evaluating how to make good copyleft hardware out of this one day. Thanks David for bringing this up! [http://marcansoft.com/blog/2010/11/openlase-open-realtime-laser-graphics/ OpenLase blog] [http://git.marcansoft.com/?p=openlase.git;a=summary OpenLase sources]
