I’ve been working on this mirrorless DSLR sized camera gimbal for a while now. As usual this project has eaten most of my time over the last month due to my obsession with needing to get results. The high I get from a succesfully completed project makes it worth it – usually.
Today was the day I claimed my high. I wish I could say this worked without any revisions. Luckily though the revisions weren’t many or too involved. The gimbal itself only required one revision. The carbon fiber tube (12mm) that I used didn’t resist twist well enough. This led to bad oscillations on yaw and pitch. Solved with aluminium tube.
The next issue I needed to tackle was the mounting system. It needed to isolate vibration, hold without flex and be as light as possible. I ended up trying 3 mounting systems before settling on this. This final design encorporates a front to back carbon fiber tube to resist flex in pitch and G10 plates for stabilizing flex in roll.
I needed to isolate the hole gimbal from vibration from the props on the hexacopter. I chose to do this with silicone fuel tubing. I drilled holes through the G10 that fit the outer diameter of the tube. Then used 3mm screws with washers on each side to sandwich the tube between the G10. This appears to be adequate from the results of the video
Aside from the aluminium tube, assorted screws/nuts and G10 the rest of the parts are made from ABS. The parts were 3d printed. The ones requiring high strength were printed at 95% fill.
What’s up next? The addition of a dedicated stabilizing gimbal controller. Currently looking to purchase a Hoverfly Gimbal Controller.
Here are the results so far:
