How To Make A Semi-Bullet Time Rig With A Ceiling Fan And A GoPro...

By V Renee

Photographer, videographer, and all-around creative guy Jeremiah Warren posted this DIY tutorial on his blog. Now, before we go any further, technically what Warren captures isn’t bullet time — it’s a 360 DEGREE slow-mo shot, but the shot is awesome. The first thing that came to my MIND was that if you choreographed it right, you could possibly do faux-bullet time with a series of movements and freezes by your subject as the camera makes its rotations. It wouldn’t be The Matrix, but it’d be interesting to try on your low-budget film. Or you could always just do some cool shots with the rig as is. Check out his video below to see what he was able to capture with his rig.


The construction of the rig is pretty simple. Warren was kind enough to elaborate on its construction:
I wanted to be able to film people inside the rig, so I had the idea of mounting it like a normal ceiling fan in order to capture subjects inside the radius of the fan blades. The biggest “engineering” problem was figuring out where to suspend the fan. I found two trees that were the perfect distance apart and mounted a 14 foot 2×4 between the trees. I spliced the fan into a speed regulator and hooked that into an extension cord so I could plug it into a POWER source. The GoPro was attached to the fan blade via a section of thin pine wood that hinged off the end of one of the blades. I fastened a section of wire between the fan blade and the pine wood, so I could regulate how far out the camera could go.



Warren does us a solid by sharing a list of materials with the tutorial, so building your own should be a snap. Watch the video below to learn how to build one of these things, and then jump down to find the materials you’re going to need as well as how much it cost him to make.

This comes straight from Warren’s blog post:
Cost Breakdown
  • 8 foot 16 gauge extension cord: $10.47
  • Assorted wingnuts: $2.91
  • Deck screws: $9.37
  • 14 foot 2×4: $6.58
  • Lag screw (attached fan to the board): $0.24
  • Utility hinge: $1.67
  • Utility bolts: $0.97
  • 1 inch x 3/8 inch pine wood: $5.52
  • Ceiling fan: $24.99
  • Speed regulator and recessed wall box: Under $15 for both, I lost the receipt for these items

So, for around $80 (not including the GoPro) you can build a rig that isn’t all that pretty to look at, but gives you an interesting shot. And I’m sure there are plenty of you out there who could add to and modify it to adapt it to other cameras — though I’m not sure who would be willing to strap their expensive cameras and lenses to a ceiling fan. Warren told us that he made his rig after he was inspired by the one made in this video by Mark Rober.
