If you happen to have an IGUS W1080-B Linear Slider and are looking for a way to get consistent movement, Servo City now offers a DIY Motorized Kit. You may have seen me working with a prototype version of this slider in a past video when I designed a simple infinite loop auto reverse switch (seen here).

With a slower motor in place you can use this to achieve long time-lapse sequences, or with a faster motor in place you can use this for real time video (noise will be apparent from the motor).

The kit comes in dozens of little pieces, but with patience was easy to assemble following the video instructions:
Actobotics - IGUS W1080-B Slider Kit Assembly (part 1)
Actobotics - IGUS W1080-B Slider Kit Assembly (part 2)

Once again, this kit is designed specifically for the W1080-B Igus Rail (which you will need first) and can the entire kit can be found at the Servo City website (here).

Here's a really great Simple DIY Motorized Video Track Dolly Project I think everyone will get a kick out of. Of course you're not limited to the design i'll be sharing in the video below. Once you see how simple it is to work with the Actobotics parts from ServoCity.com, i'm sure this will spawn a new breed of DIY Motorized projects, so make sure to share what you've come up with by commenting on this blog article.

Every little part used in the project is extremely high quality and precision made, so in the end everything lines up perfectly. It so simple, i'm confident my 12 year old son can easily put one of these things together. Everything used to assemble this high quality motorized track dolly project can be found over at ServoCity.com down to the roller skate wheels, bearings, and tiny hex screws.

Did you notice how quiet this system is? There is only a bit of noise, but you can see how my LAV mic didn't even pick up any noise as it tracked side to side.

The wheel assemblies position the skate wheels at an angle to use basic pipes as your track. You can choose to use inexpensive PVC pipes, Conduit, possibly Angle Iron, or whatever else you might find convenient for your project.

Only one drive wheel is needed to make the system move, and you can choose various RPM speed motors depending if you want to track quickly or slowly. With a Speed Controller you will still have some variations in speed as well as having a simple forward/reverse switch.

Here is a few reference videos from ServoCity.com showing you how to build the Drive Wheel, the Idler Wheel, and also options for assembling a frame to the wheel assemblies.

Frame Building - Aluminum Channel or Tubing

The Frame I have here is using 12" Aluminum Channel and it was able to support over 100lbs of weight with ease. I seriously placed a chair on this frame and took a ride along a conduit track (this is not recommended, but I wanted to try it). Perfect for even the heaviest cameras out on the market including RED, and for rigged up SONY FS700 Shooters.

I think I want to shrink this down using 6" Aluminum Channels to reduce it down to half it's size. All I need to do is add a flat platform over the frame (i'm thinking thick plastic cutting board material from Ikea) so that I can mount a standard video Fluid Head in the center, and this is will be one seriously light-weight (yet heavy duty) smooth motorized video track dolly.

Unfortunately they don't sell a complete kit so you'll have to be familiar with every little part required to build one of these DIY Motorized Video Track Dollies. You will also need to add a few wire leads to the motor you choose, and pick up a 12V battery pack. Not really a big deal.

So to make things easier for you here's a parts list for the different components of the DIY Motorized Video Track Dolly in my video. Keep in mind you can easily come up with a variety of different shapes and sizes by assembling the parts differently. The one I share is also using 12" Aluminum Channel, but you can go smaller or larger depending on your project.

For projects like this, I highly recommend picking up these CCTV 12V Rechargeable Battery Packs. They are very cheap (some around just $10 bucks), small, lightweight and should be enough to power your Motorized Track Dolly.

Whether you are working on this DIY Project or others, these 5.5mm OD + 2.5mm ID Terminal Connectors are pretty standard across many DSLR Video accessories. This will plug directly into many LED Video lights, and will plug directly into your CCTV battery. It's a very simple way to add a terminal plug to the end of wires without soldering. The Male and Female combo connect to each other so you can make a quick disconnect type setup between two wires.

ServoCity.com posted a recent video showcasing the movement of it's latest MPT1100-SS Open Looop Pan & Tilt System. The $650 Dollar unit is designed to mount to camera Jibs / Cranes to remotely control the movement of the camera through a simple Joystick. I have a small video insight of this unit in action and the parts breakdown in an earlier article (seen here), and you can already find the new MPT1100-SS Motorized Pan & Tilt system available at ServoCity.com (click here).

Not long ago I quickly showed a new motorized Joystick controlled Pan & Tilt head from ServoCity.com. This was a product they were working on for a little while and I know many of you were already communicating with ServoCity.com about this. At the time I only had a prototype here and they were only a few days away from a final product. So I decided to wait until I received the final unit before mounting it to my Jib and testing everything out. The final product should arrive (maybe this week), but in the meantime they have already listed the unit on their website as the MPT1100-SS Pan & Tilt System and it looks like it includes everything you need to power up and control the head (found here).

[Update] This is a new OPEN LOOP system that is not yet available. NOT CLOSED LOOP. Sorry, for the confusion.

New Motorized Pan & Tilt head from Servo City. I used these guys to pick up some parts for the DIY motorized Juicedlink Slider project (here), and at the time they didn't have quite the Pan & Tilt head available for the end of a Jib / Crane. After discussing with them what I was looking for, they mentioned they were working on a new 'Open Loop' system that would allow me to operate the camera through the joystick control.

So here it is. It's a new Pan & Tilt 'Open Loop' system with Joystick control. Construction is top notch, and I don't know of a cheaper system out there. The product is not yet available, but it will be in a few weeks at ServoCity.com (Click Here).
