Indeed, still I'm quite busy with other stuff and do not have any time to do a real update on the blog. I hope to be able to write something new this month and later, next month, when I'm back from vacation, to start updating this daily.
Not much progress was made recently, as I was in Austria for half a month. But now things should speed up a bit, as I'm going back to this device - http://www.nikodem.blogspot.com/2012/02/some-initial-evaluation.html as I plan to use it to digitize the data from my picoammeter.
