Picture of Lego Time Lapse Dolly

I wanted to create time-lapse dolly for my camera. I did not want to ride only on the tracks. Thus, the truck can travel, on the ground, on a bench in the park, porapetu windows, etc..

Step 1: Construction

I used lego blocks, I could build as needed. The lego cube is great that you can build by themselves.

Step 2: The Electronics

All the parts I bought on Ebay:

Stepper Motor Driver ($1.19) http://www.ebay.com/itm/161304707166?_trksid=p2059...

Arduino Nano V3.0 ($4.76) http://www.ebay.com/itm/171337374773?_trksid=p2059...

JoyStick ($2.09) http://www.ebay.com/itm/200955114766?_trksid=p2059...

Remote Switch for Olympus ($2.48) http://www.ebay.com/itm/300839084245?_trksid=p2059...

5V DC Relay ($1.00) http://www.ebay.com/itm/Mini-5V-DC-Coil-Power-Rela...

Cable for Arduino ($1.48) http://www.ebay.com/itm/40-root-For-a-row-of-Dupon...

3.5 Jack connector

I cut the Remote Switch and I soldered Jack 3.5 connectors for use with the Arduino and the remote switch.
The relay I soldered wires to be connected to Arduino. Everything we connect to each other: arduino -> Relay -> jack -> jack connector for Olympus -> and my camera.

Next, I added Stepper Motor Driver to Arduino. To him I joined a stepper motor, and, 5V adapter or battery pack.

Another thing I want to connect the joystick. He will control the speed of the wheels, and frame rate. The rate will be adjusted by tilting the X-axis and Y-axis and after pressing the button, the value will be deducted.

Step 3: Arduino code

I uploaded code via Arduino program. The program includes both shoot camera and rotating the stepper motor.

Step 4: The first testing

Interesting. Any video examples of how the lapse turned out?

I added a video of the first test, but poor quality. I am still working on improvements.

Nifty! Could you post more pics of the Lego vehicle construction?
