Motorized camera sliders can really improve the quality of your videos and time-lapses, but they're also rather expensive. With a little bit of savvy, however, you can build your own relatively cheaply and in just a few hours by following this great tutorial.
If you're a nerd like me, you'll find this project immensely satisfying. For about $75 and an afternoon of your time, you can create your own motorized camera slider with 15 distinct speeds ranging from seconds to multiple hours (or whatever you care to program). If you've done any work with an Arduino before, it's a pretty straightforward project; if not, it's a great way to get your feet wet. Camera sliders are a fantastic way to add motion to your work that can take a static shot and create a more compelling experience for the viewer, making them one of those pieces of equipment that instantly up the caliber of your work.
A list of all of the parts you'll need as well as full written instructions with accompanying images can be found here. If you're not comfortable with building your own, a good slider is still a worthwhile investment. Grab your own here.

Make your own...IF! You have all these special tools and gear a metal working shop would have, and have the knowledge in house to use them...Wouldn't really consider this a general "DIY"
A "product design engineer" and he labels the 1-4 speeds with 4 being the slowest. Um...yeah... Plus a lot of trial and error drilling without checking clearances.
But he did it, instead of criticizing someone else's work like some other people do;)
Your reply was useless. I'm a mechanical engineer. Since all those simple on/off switches are just mounted in a custom bos, it's very easy to mount them in reverse. But if his logic dictates it then so be it. But I would mount the slowest switch first then progress to faster as the numbers increase.
I am sure you would... but you won't... :D
Its a standard binary counting system common on dip switches in remotes (garage door openers etc) and other electronics. In this case the right most position (4) is the first bit where 1, 2, 3, 4, would be 0001, 0010, 0011, 0100. This is the easiest way to maximize inputs with a limited number of controls and without the need for displays or feedback.
I used to teach my friends how you could count to 1,023 on just your fingers using binary. :)
