First of all, a happy new year!
I am quite new with the RPi. I bought one last november and started experimenting with it.
After creating a simple (experimental) bufferboard with an ULN2003 Darlington array, I wondered if it was possible to use the RPi as an IR server for the Lego trains of my daughters, using my iPhone/iPad as the remote.
I just started coding, using the Lego Powerfunctions library for the Arduino as a starting point, to build the server part. Next I created a simple app for my iPhone/iPad. At the moment I am able top run (at least) two trains simultaneous, but it should also be possible to control 8 trains at the same time.
My next project might be a remote controlled car using the RPi, again, as the IR server.
Are there others who are trying to use the RPi as an IR server for their Lego projects this way, and is anyone interested in the 'server' project I created.
Would love to hear more.
