just made one myself.


2 minutes of thinking, 5 minutes of sourcing items around the house, and about 3 minutes of build time.


attach a long string to the non camera end of the phone. then on the string, about 2 inches out from the phone, attach another bit of string and fix it to the camera end of the phone (out the way of the lens).

then i used some kitchen towel to make a tail, which i attached at the camera end of the phone. This creates drag which helps keep the camera up right.

Ive got one of those suction cup mounts to hold my phone in my car. its got like a pincer holder. i'll maybe see about modifying that.

Ive decided to make a little project, and its only to be made with things I find around the house, no specialist tools, and then i'll be able to post simple instructions on how to make one

Yep. Getting the balance/angle right will be key and it will depend a lot on the arrangement and weight of all the other materials. I am going to pick up some heavy duty fishing line (like 100 lb. test) but I need to come up with a reusable case the phone can go in/out fairly easily. I don't want to duct tape the entire thing!

My initial tests have not gone swimmingly. I picked up two lengths of 60 lb. fishing line. With an iPhone 6 the distance has to be approx. 15 feet to get the right field of view. I ran the two lines out to dowel and taped an old junk phone to the dowel with a rag hanging off the back. I could not even come close to getting it swinging. I added 6 x 1/2 oz. weights I also picked up and that helped, but I think I still need more weight. Unfortunately it is too dark now (and my wife won't help me) to see how well it is tracking. In my hand I have a dowel with swivel at the top so if I get it swinging it won't twist the lines.

I'll give it another shot tomorrow in the daylight. 15 feet of line is a darn long ways to get it swinging. Right now I am waving my whole arm just trying to keep it moving.

Interestingly the skier in the video has made a mount where the phone extends off the front of whatever he is swinging because you can see the lines behind the camera.

I assume the bigger the mount, the more steady it is. It would be good to make a mount that a gopro can sit in, then the wide angle lens will mean you don't need the string to be as long. In fact my friend has a fish eye lens attachment for her iPhone thst works a lot better than I thought it would

Like a retractable cord? Reminds me of an employee badge or one of those leashes for dogs
