Device to record gyro data for old cameras

[Clark Nikolai]

Last year I experimented with a Digital Bolex and an iOS app that recorded the gyroscopic data from the phone. I took the footage and the phone's sensor data in Gyroflow software and was able to stabilize the footage. It worked well and I was impressed by it but cumbersome in the field to shoot with as you have to start the app and then start rolling the camera, it was more trouble than it was worth for me at that time so I didn't continue with it. 

Now I hear about this new product called Niyien Senseflow A1. A tiny little thing that you can put in your cold shoe and only have to start it once per day. Seems pretty neat. I'm pondering getting one and trying it out. I'll let you know how it goes. Does anyone on here have one and can give their experience with it?
