  • Android Phone

    Last week I got my new phone. A Samsung Galaxy 9000 with Android 2.1 (soon 2.2). So, the Openmoko Freerunner was my main phone for less than a year. I tried many different distributions on it.

    With my flugbuch2 and flightpred projects I had a problem for a while in the debian packages.

As the first part I wanted to read the anemometers. I got them for a bargain from Touch&Go. Only I couldn’t figure out how […]

  • Handheld 2.4GHz Spectrum Analyzer

So I was looking for anything that could help me in doing so. Then I stumbled across Miguel A. Vallejo’s Handheld 2.4GHz Spectrum Analyzer. […]
