New way to control LEGO trains?!

Interesting. Maybe wind turbines can be a good place hide the LEDs too. Can you add additional IR LEDs to the satellites for more power?

There are no IR LED's in the GOT satellites. The satellites receive ultrasound from the trains for positioning data and then uses radio signals to communicate with the master controller that are connected to the computer. The trains have a little GOT controller unit connected with an IR-sender strapped on to the LEGO PowerFunction IR-receiver with double sided tape. And the train controller gets power from the PF battery pack and uses radio signals to communicate with the master controller. And it also sends out a ultrasound code (or something) from a little speaker you mount on the roof of the train for positioning data.

You do not need free sight to the train for controlling the train. You can control it even if it is inside a tunnel. But you can not get the positioning data when the satellites can't get the ultrasound from the train controller.

The only thing I miss with this system is able to have motor control also on the second port on the IR-receiver, not only turn lights on/off.

The sound chip is connected directly on to the train controller and do not use a port on the PF IR-receiver.
