The world’s largest model railway exhibit — on display in Germany of course — is quite the attraction. The huge Miniatur Wunderland features towns and trains from Germany, Switzerland, Austria, and even a little America. And it’s all on Google Maps.
[Frank] accepted the challenge to build a tiny Google Streetview train, capable of traversing the entire Wunderland. It features a fish-eye camera on both the front and rear car, and is powered by an Arduino — the Wattuino Nanite 85. He upgraded the train to use tiny stepper motors to allow for precise movement along the tracks to get all the shots in perfect Streetview fashion.
It was a challenge keeping it small enough to be able to go through all of the train tunnels on display, but the end result is fantastic. Makes us want to slap on a pair of VR goggles and ride the train!
