Has anyone worked with brushless DC gimbals such as the MoVI or, has anyone tried assembling their own?
I've been doing some research and you can get parts kits that include BLDC motors and the the entire gimbal frame that requires assembly for around $350 bucks, see ebay link:
And then add on your controller and firmware board and sensors ranging between $20-80 bucks more depending on a few options such as a joystick or bluetooth to make use of the android app to calibrate the gimbal in the field, see ebay link:
Then add a cheap battery and charger and you're pretty much set for around 500 bucks, which is in the price range of a new HD2000, AND you get to feel like a kit on Christmas assembling your new LEGO kit
This would require basic circuit knowledge to follow pin outs on the boards for motor, sensor and battery connections, as well as soldering experience for both the board and motor leads, then heat shrink your wiring harness and make it look all pretty.
