What is up guys, In this instructable I will be making a very simple and cheap motorized camera slider for less than 15$. Hope you are gonna like it :)

Step 1: 3d Modeling and Design

I designed all parts of a camera slider in 3d software called solidworks.

Here is a quick video how I plan and design everything up and after that I slice all parts and print them out.

Step 2: Parts for This Project

So, here are all basic parts we are gonna need to build the slider.

►Solidworks files: https://goo.gl/6dQE9x

►PART List:

- 1/4 inch knob: https://goo.gl/Rb32dN

- Pulley belt: https://goo.gl/jxfpZk

- Pulley Wheel: https://goo.gl/jxfpZk

- Linear bearing: https://goo.gl/jxfpZk

- Voltage regulator: https://goo.gl/jxfpZk

- DC Motor: https://goo.gl/jxfpZk

Step 3: Assembling Parts Together

So, I firstly mounted two linear bearings to the base with some very short M4 scews.

Then I attach two 50cm aluminum pipes on the left leg with a help of a hammer, slide on the base and again hammer down the remaining right leg so I get a nice a sturdy frame.

The basic sliding function is achieved, If you want you can make a manual slider without a motor which is totally fine and usable for some fast transitions but that is not what I particuraly wanted so lets use the same DC motor that I use when I made a rotary table and mount it to the frame with the same M4 nuts and bolts.

After that I secure the pulley to shaft of the motor and tighten the pulley belt with some zip ties.

Step 4: Reverse Polarity Switch

Now, we need to make a reverse polarity switch and the simplyest way to do that is to use a DPDT switch aka double pole double throw swtich, which has two seperate channels and with that simple circuit we can switch the polarity that goes to the motor.

After that I install the switch and a voltage regulator to the frame, solder up and hide the remaining wires and we are finally ready to test the slider with a 12v power supply.

Step 5: Finial Touches

It is working really good and again you could stop at that point but I want to mount my slider to the tripod so I cut a small piece of wood on my saw, drill a few holes and attach a quick release mount under the slider.

Lastly, I screw in the ¼ of an inch camera bolt and install the 9V battery so we can take our slider outside and make some crazy looking shots.

And there we have it guys, A simple and easy to make camera slider which you can take with yourself on a trip and shot some crazy videos.
