Train Music!!
August 10th, 2009 by RoscoHead
This is probably my longest lasting MOC project to date. Back in 2001, I realised that the 6 speeds of the LEGO train controller driving a standard 9V motor produced the first 6 overtones, ie: the notes available to most valve-less brass instruments. I didn’t do anything more on it until yesterday, when for some obscure reason I decided to finish the project.
So here it is for your enjoyment (or otherwise).
