Here's a look at a prototype motorized trailer sent to me today and it's attached to a PNC Pico Dolly. Still a prototype, it's supposed be universal and have some mounting options to attach to several different dollies or maybe even sliders? The idea is to have a motorized push cart to have consistent movement all of the motors, batteries, wiring, and switches all self contained into one little unit.
There's a few 1/4x20 threads to mount other accessories on the little push car too. From the image it looks like it's around 4" wide. I have no additional information about availability or pricing at this time. What do you guys think about something like this? For more about the Pico Dolly, you can find that information at the following page: https://www.photographyandcinema.com
If you have the means, the space, and the transportation, ladder track dollies are a great solution for camera movement. Rod shows how he's picked up a set of ready-made 'bolt on' dolly wheels to a simple plywood board to create an 8ft dolly capable of carrying a good amount of weight. In smaller more confined situations a slider is a must, but there's plenty of benefits to using a wider platform for stability in your shots.
These dolly wheels are designed to run on pipes as well, but when possible using a Ladder will provide a very firm solution that can be laid out in just about any type of terrain (gravel, grass, mud) and still maintain a super rigid track - unlike long PVC pipes. In this older article you can see how a ladder was used for a DIY Timelapse rig: https://cheesycam.com/diy-motion-controlled-timelapse/
If you're intersted in building your own dolly system, you could try some angle iron and at least 8 skate wheels + bearings, but if you're slightly off in drilling it's going to cause you quite a bit of wobble. To make things easier, these wheels that Rod is using are an inexpensive solution.
We all DIY with what's available, convenient, and affordable. One of those materials is found in the household section in your local grocery mart. I tell ya, IKEA must be making a killing on cutting board sales. First seen on a DIY DSLR Rig, and then played a small part on a Slider, and now here's another DIY camera slider from Vimeo member TaQ Inoue.
I'm not sure it's an actual IKEA cutting board, but you can get the same hefty material there in large sizes. It's cheap, easy to cut, carve, drill, and shape. Not very clear on the details or specs here, but it's a good excuse to creatively shoot the project from beginning to end. Overall costs stated at $30 dollars. It also seems to be working out fairly well in his example video 'Littlest Mountains 2 Trailer'.
New double rail camera slider design (or dolly) on the market. This one doesn't look like it comes off the rails for some smooth table action, so it's pretty useless except to roll on it's rails. Very little specs, but it looks like standard 15mm rods with tripod mount ends. Even if it doesn't come off for the tables, the very simple design looks like it would be very efficient as a straight slider and with wide rails looks pretty stable. Very cool to see a bowl mount for quick leveling too. Pricing is just way too high to make a move on this market...
If you're looking to get a real double rail slider, the best one on the market would be Cinevate's Pegasus. Not only does it run on inexpensive rails, but it comes off the track for all that smooth table action, as well as a rotating dolly shot. Nice little example put together by Cinevate below. Found here: https://Cinevate.com/Pegasus
Vimeo member Lolo Two is at it again, but this time with a more 'polished' (no pun intended) version of his DIY Conduit Slider. The first version here: https://cheesycam.com/diy-conduit-camera-slider/ using 1/2" conduit piping looked like a simple build, but this new version (the Big Brother) with more surface area, polished piping, and double the couplers seems like a very solid build. You'll notice the smooth tracking with a simple push from a screwdriver, and the amount of weight thrown on with a Cinder Block. Very very cool stuff. [Thanks Lolo Two]
Can't decide between a slider that 'just slides' or a slider with actual 'roller bearings'? (Technically, I guess that would make it a roller) There's a mix bag of shooters who prefer one over the other, but here's a new 'tweener. Glidetrack was teasing everyone with their new Hybrid camera slider a few weeks ago that uses a new hybrid Roller/Slider bearing, and it's now available to purchase online.
Looks like it's still based off of the IGUS Drylin rails with the new IGUS Hybrid bearings, but there's some custom work done on the actual carrier and adjustable legs. Obviously price is going to be pricier than the normal versions from Glidetrack. In fact, for the price of 1 single Glidetrack Hybrid you could almost score two Konova full roller bearing sliders of the same length. No descriptions on variable friction, but there is a hard brake stop to keep it locked down while moving around. If you're interested in hybrid designs, the Glidetrack Hybrid sliders / rollers are available in a variety of lengths from 20" (0.5m) - 78" (2m). You can find the prices below.
You post a few DIY sliders on here and it opens up a whole can of worms. I've received lots of DIY slider ideas, but if it's too similar to what we've seen before, then i'm not going to get too redundant showing it again. Here of course is another DIY slider version with great results and all based on a platform of furniture sliders. Yeah same little low friction smooth plastic stuff you place under your chairs and table legs. The key to this design is the very wide rail that is used to support the width of the fluid head and wide platform. Lots of area for stabilizing movement. [Thanks SkaliTV]
Bad News (well not really bad), this is a Pre-Order listing for the next batch. According to the details, it won't ship until the end of the month. How many will be counted for in this next batch? Who knows, but the first listing was taken down in the same day of my last post. Other good news is that it's come back online for the most recent price we saw it at. Now I know several people missed out on the auction listing and are getting eager about this camera slider and going to buy direct from manufacturer. You could throw some money down, but those are still pre-orders with nothing in stock to ship out. If you want to make sure you're playing it safe on a purchase, eBay is the way to go - Paypal has got you covered. Hopefully a few of them will start coming in from previous shipments so we can get a review online, but here's the new listing if you're already convinced.
Here's one of my favorite DIY videos that was actually shot over 2 years ago by Vimeo member Edwin Bont. I've been wanting to tackle this project myself, but am always getting sidetracked. It might be on my list of things this weekend if i'm not too backlogged from CES. It's a video that hasn't had much attention, but a very original DIY in what is called the 'Sphere Arm'. This rig uses a set of L brackets cleverly assembled to keep the lens at a fixed distance while allowing it to be rotated in several axises. This not only gives you the illusion of rotating horizontally, but also vertically.
The build quality on the one shown in the video isn't very heavy duty and video doesn't seem to be of high quality, but i'm sure with a bit more DIY out there this thing can really bring in the 'next camera movement'. Might even be an interesting movement with small cameras such as the GoPro and light weight GH2. Wedding videographers, I can totally see this as a macro video movement around some wedding rings. Yeah, I think this idea has been asleep too long and needs to be hashed out with something more refined. Besides myself, (if I can get to it) who else is up for the challenge?
