Karl Zweimüller

Trying to get into electronics and microcontrollers again with mbed after many years of absence. Have an mbed an 2x16LCD, 2 DS1820 , an mechanical rotary-encoder some RFM12B and RFM22B transceiver-modules and I'm playing around with these and see what comes out....

Another hot topic is "self-made knx" : http://www.freebus.org/ I've got some components up and running in my new home.
