• Lattice Semiconductor released version 3.8 of the Mico32 core, with a few minor new features and bug fixes. Most importantly for us, they clarified the license header at the top of every source file, from one that could be misunderstood by the casual reader, to one that is now fully and 100% clear to be open source.

• David's link to OpenLase [5]
• Cristian Paul had ported the namuru correlator to the mm1 soc (thanks Fabrizio Tapper and Peter Mumford for valious support), this IP core will allow to speed up the correlation process for getting a fix and track gps satellites, WIP is currently going the osgps receiver that will provide a high level software interface to process navigation data tracked with namuru (link to repo, namuru specs??..)

Also with the key help of David K, the SoftGNSS matlab code is now finally ported (link to repo) to octave, this also will allow offline analysis of raw real-data for a variety gps front-ends in the market.

• Xiangfu Liu made the best quality recording of a Milkymist One performance so far.

Homebrew CMOS and MEMS foundry design

• Andrew from homecmos project had improved a lot the process for making home-brew MEMS from a lithographic projection, by irc channel he shared last results from his lab progress, and quoted it like: "World's smallest nyan cat", checkout some pics:

Nyan Cat head, zoom 400x

Pixels are 20um square.

cat overal body zoomed 100x

Cat is around 600 microns long and 200 high.
