Hi guys,
I did manage to setup the Whiteboard software and have two motes available.
Just have to make sure that I do not experiment when the kids want to start Bowling

Did not make a pen yet, tried it with a normal remote for TV, but that does not work
for obvious reasons. On the other hand, it proved that the technique is working.
Now find some spare time to assemble an IR pen.
Have a nice weekend!
Rene
