  • Lars-Peter Clausen and Michael Walle improved Linux 3.0 on Milkymist One. [1]
  • Lars-Peter Clausen ported an OpenWrt userland to Milkymist One, with static linking and uClibc. [2]
  • Xiangfu Liu setup daily builds of OpenWrt for Milkymist One. [3]
  • 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. Lattice Download Comparison of old and new licensing header
  • Christopher Adams designed a new Milkymist logo and selected the free Orbitron font for logo and branding.
    roh from Raumfahrtagentur engraved a mirror version of the new logo on the inside of the top acrylic for the upcoming RC3 run.

  • Yi Zhang finished the Milkymist One box design and sent it off to the box makers.

Thirteen wires in and out of Milkymist One during production testing.
  • 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. [4]
  • Cristian Paul ported the 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. SoftGNSS repo
  • Jon Phillips gave a talk about Milkymist One at FISL 12 in Porto Alegre, Brazil (slides of talk below). [5] [6]

[edit] atben/atusb

  • Werner finished designing the ben-wpan boards, a set of IEEE 802.15.4 wireless dongles. [7]
Range of ben-wpan boards measured at Werner's apartment in Buenos Aires (dimensions in cm).
  • Werner wrote documentation and tools for the production and testing process of ben-wpan 802.15.4 boards.
    A total of five pages, overview page and four detail pages. Announcement Overview

[edit] Copyleft Hardware Explained

  • Werner Almesberger published a two part comparison of Free scripted CAD tools - Part 1, Part2.
OpenCSG, showing artefacts
OpenSCAD, modeling artefact (internal structure)
OpenSCAD, modeling artefact (reversed face)
  • The names of component packages are often confusing and vary among manufacturers. This is Werner's first step (for small logic gates) towards a packageology.
  • Some data sheets don't contain all the information necessary to make Copyleft Hardware. Here is Werner's anatomy of a datasheet.

[edit] NanoNote

  • Jadon Dutra made two nice Ben NanoNote tutorial videos. [8]
