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.

Biking cross-country is a worthwhile pursuit, but then you’ll have to deal with terrible drivers, rain, bugs, and heat. [Jeff Adkins] over at lowendmac has a neat solution to exploring the country via bicycle without ever leaving the safety and air conditioning of your basement.
For his build, [Jeff] used a magnetic reed switch attached to the frame of his stationary bike and the pedal crank. Whenever the pedal crank is turned, a reed switch closes on every revolution. This reed switch is connected to a new Arduino Leonardo programmed to transmit keyboard presses to a computer for every five revolutions of the pedal. From there, it’s a simple matter of loading up Google Streetview on a laptop and letting the Arduino automatically advance through Streetview images while pedaling.
The next part of [Jeff]’s project will be adding left and right buttons to his stationary bike to navigate Google Streetview images without taking his hands off the handlebars. You can check out a demo of [Jeff] cruising around after the break.

[Mark] was playing around with a small GPS sensor when a light bulb lit over his head. He imagined it would be pretty cool to replicate one of Google’s Street View cars at a fraction of the scale using Lego NXT parts. He figured it would be easy enough to rig a few cameras to a remote controlled car, recording images and GPS coordinates as it went along.
The mini Street View car is controlled by a single NXT module that receives commands from a PS2 controller via a PSPNx sensor he purchased. A trio of cameras have been attached to the car, which are meant to take pictures in all different directions when triggered by his remote. A handful of additional motors are also used for driving the car, steering, and for activating the shutter release on the cameras.
The car worked decently during testing, but [Mark] says there is still plenty of room for improvement. He is having issues reliably triggering all cameras at the moment, but we’re sure he’ll have it sorted out soon enough.
