Beside my HAM radio stuff I also fly model helicopters.
I own three electric helicopters two of them are 6ch collective pitch and the smallest Walkera CB100 is an fixed pitch 4ch helicopter.
Model N-gauge trains:
Model trains have also my interest, I’m still in the process of collecting points and tracks. However I have build a tiny scenery for Xmas.. a one track rail. Small mountain with a motion-sensor. This sensor trigger a Arduino micro controller setting the train motion in different way’s.
Arduino micro controllers:
Writing C++ software is fun to do, I own several Admega micro controllers. I have owned the Arduino uno v3 and have the Arduino Mega and several Arduino Nano’s in use. The Uno’s are extremely handy while controlling my model N-gauge trains. On the Arduino Mega I have written a program to control a track with four points and two stop signs, the locomotive speed is also controlled by the Mega using PWM (Pulse With Modulation)
