The hat was a nice touch, too. What a wonderful instructor this man was.

There was a time that lectures were fun and not just computer simulations.

Makes me wish I still had my train set from childhood. Great video - Dr. Roberge was always fantastic!

[@markposner7803]

So cool! I recently just learned lead / lag control and it's great to see in practice.

Thanks a lot Professor!

I am working on a PWM controller for my Z scale using a PIC microcontroller but it works from the rails not the engine.

Have I just watched the birth of DCC in railway modelling???

[@tonyfremont]

It was certainly a gleam in his eye.

I only use fake trains, like N scale.

Seems that personnel with high IQ loves trains.
