Hey everyone. I'm looking to build my own handheld gimbal for my Gopro like Alex did in this video. http://youtu.be/uHFLiGFWpvs
I've seen that there are a lot of 3 axis handheld Gopro commercial mounts for sale online. My problem is I would like one like Alex made in the video but want to be able to mount my GoPro in its case. I plan on using this mostly going through canyons and rappelling so I want to be able to keep my camera semi protected incase I drop it or bang it against something. I like Alexs design because it's simple. My question is, do I need to buy one of the new 32bit controllers to achieve results or can I get away with using version 2.4. If I can use version 2.4, what would be the best firmware to use for a handheld gimbal like Alex made? Also, I notice he used a different motor for the yaw control than he used for pitch and roll, is this necessary? Any suggestion on motor sizes to power a gopro inside it's case? Thanks in advance everyone for any help. I would really like the satisfaction of building my own instead of buying a commercially made gimbal
NO SUCH THING EXIST! Sugest you use a NEX gimbal mount gopro with the case on that. other option is to use Ebay gopro gimbal with full aluminum enclosure.
You can use same motor for all axis if they are strong enough, but Pitch and Roll do not need to be as strong as Yaw. For handheld GoPro gimbal I would suggest to use bigger motors than needed. I would suggest some flat motors on the range of 36 to 40 mm diameter range. Also build the gimbal strong, stronger than you think you need.
32 bit board with 2 IMUs will work better especially on strange positions and they are more compact. For this kind of application I would strongly suggest using rain proof box for the electronics and joystick is nice to have.
