A step-by-step guide to create a “Centripro” - a device used for orbital videos with your GoPro!

What is a Centripro?

We’re guessing the term “Centripro” comes from the words centrifugal + GoPro; basically implying you’re going to spin the camera around in circles using centrifugal force. The centripro device we’re making today is essentially a GoPro mounted to a clothing hanger and spun around your head with fishing line. The origins of this homemade device were said to come from an action sports guy named Nicolas Vuignier. Apparently he made the first one for his iPhone, a Centriphone, and then developed a version for the GoPro - a Centripro.

Chances are you’ve seen these cool orbital videos before. They’re typically in slow motion and show some interesting action 360° around a person. Shots like these are often achieved in Hollywood movies with expensive equipment like a 6-axis robotic arm. Most of us don’t have the budget for movie equipment like that. However, did you know you could make a similar video with a GoPro and a few inexpensive household items? There are many different ways to make this device. I’ve tried a handful of different methods and settled on what I think is the most effective and cost efficient.


What you'll Need:

Supplies:

  • GoPro (any works, Hero 6 is best) + Sticky Mount & Clamp
  • Wood Hanger
  • Strong Clear Fishing Line (at least 20 feet)
  • Flagging Tape
  • Packaging Tape
  • ¼” x 2” Bolt
  • 3 washers (that fit on the bolt)
  • Key ring
  • Zip Ties (optional)
  • Wooden Dowell or Wooden Rolling Pin Handle

Tools:

  • Pliers
  • Drill + ¼” or ⅛” drill bits
  • Scissors

Step by Step: How to Make a Centripro:

Step 1: Remove the metal hanger 
Fig. 1
and wooden cross pole.
Fig. 2
 
Step 2: Peel and place the GoPro sticky mount centered at the apex of the hanger. 
Fig. 3
 
Make sure the mount is centered and aligned. 
Fig. 3A
This portion of the hanger may have a slight curve to it so be sure to press and hold the sticky mount firmly until adhered.

Step 3: drill a hole near the end of each leg . You can use ⅛” or ¼” drill bit.

Fig. 6
 
Step 4: Attach the GoPro clip to the mount.
Fig. 7
 
 
Optional: I used zip ties around the clip to ensure that the mount would stay attached. I wrapped 2 zip ties and secured them around the base of the clip in case the sticky mount failed. You could also use duct tape. Zip ties or duct tape isn’t required but gave me peace of mind knowing the GoPro would be extra secure to the hanger.

Step 5: Cut 5 to 10 strips of flagging tape at about 18” long.
Fig. 9
These flags are what will keep the Centripro stable while it’s being swung around your head. Stack all the strips of the flags and tape them together at one end.
Fig. 10
 
Once taped together, pierce a hole through that taped end of the flags.

Step 6: Attach the key ring through the hole of the flags.

Then attached that keyring through one drilled hole of the hanger’s leg.
Fig. 13
  
Step 7: Lace the fishing line through one hole and tie multiple strong knots.

Fig. 14A
Pull out at least 15 feet of fishing line and cut it.
Fig. 15
 
Lace the other end of the fishing line through the other drilled hole on the opposite hanger leg (the hole with the key ring) then tie multiple strong knots.
Fig. 16
 
Step 8: Pull both ends of the fishing line out about 2 feet and tie them together to create a V shape.
Fig. 17
Fig. 17A
Step 9: Tie a knot to a washer about 3 feet down from the V knot.
Fig. 18

 

 

Cut off any excess fishing line.
Fig. 19
Note: The total distance from the hanger’s legs to the end of the fishing line should be about 5 feet. (this is a good radius for swinging the camera and capturing video of yourself without being too far away).
 
Step 10: Sandwich the washer with the fishing line between the other two washers onto the bolt.
Fig. 20

 

 

Next, drill that bolt into the end of the wooden handle or dowel.
Fig. 21
Be sure not to drill it all the way into the wooden handle - leave a couple millimeters of space so the centripro can spin with as little friction as possible.

Boom, you're done!

Final Step: Go Try it out! The video looks best when filmed in slow motion (See our previous blog post here on how to shoot slow motion with the GoPro). I’ve found the best video settings with the Hero 6 are 2.7k at 120FPS with the “video stabilization = ON”. This will help with any shakiness that may occur when swinging the camera around in circles.

Make sure your GoPro is securely locked into the clip mount. Then angle the GoPro so the LCD screen preview doesn't show the hanger’s legs in the shot. Once the angle looks right, tighten the thumb screw tight.

 


Filming Tips:

When spinning the Centripro, make sure you start slowly with a lot of open space around you. The GoPro should be hanging upside down and the flagging tape should be on the trailing end of your spins. Do a couple test spins and check the video on the GoPro to be sure you're captured your body and none of the hanger.

Try doing an activity that will look cool in slow motion. For example: running, jumping, throwing a handful of leaves, spraying water, etc. Get creative with it! Once you’re done filming, bring the video into your preferred editing software and slow down the video for a cool bullet-time effect.
