Still lots of snow on the ground, and a temperature just barely above freezing this evening. The first red (slow) bit between #19 and #20 could not be avoided - just too much snow for running.

Continuing north on 101 and then 580 east towards Richmond … Continue reading 5 day California/Nevada/Arizona roadtrip

My PhD work involved the design/construction and application of an Optical Tweezers instrument at the … Continue reading About
The DSM system by Spektrum RC (www.spektrumrc.com) is a new and exciting development. I got my RF-module and receiver ahead of the radio that I have also ordered so I have time to inspect the DSM parts before trying them out...
