I just added support for GoPro Hero 3(+) to the MotorPixie Gimbal. Find it at Thingiversehttp://www.thingiverse.com/thing:363690.
Project MotorPixie - Open Source 2-axis gimbal for P2V
- Thread starter DKDarkness
- Start date
You are the MAN. I am printing out right now and will assemble this week. What settings are you using with your controller. Can you post a profile or send.DKDarkness said:DKDarkness said:A little status update:
This is what it looks like, when I do my testing: http://youtu.be/ApPEFi2EdyM
The most recent files for 3D printing can be found here: http://www.thingiverse.com/thing:363690
Please note that the design: http://www.thingiverse.com/thing:363690 has changed:New versions 22/6/2014:
* Updated FC200 enclosure to make adjusting balance point easier
* Updated pitch arm to make adjusting balance point easier and there is now clearance 360.
* Updated baseplate to accommodate 360 clearance and nicer cabling.
* Updated BaseCam case to make board fit within confines of box. Easier access to cables. Reduced height by 1mm.
Note: IMU box is subject to change.
Appreciate all your help and time.

This looks nice!
So has anybody printed these by a commercial third party printer? Would love to know how much they might charge. I don't even know... are there shops that print at higher or lower "resolution"? Any pointers?
And what material are you folks printing in... what's the right balance between strength and weight?

Printing in ABS, layer height 0.2, 40% infill seems to be the best strength/weight ratio. You are looking at approx. 65g of material total.
On Shapeways.com, the baseplate alone will cost €71.50. The material cost for the baseplate when printed in ABS would be around €0.80.
The initial cost of a 3D printer (XYZ Printing: $499,- / Solidoodle 4: $899,- (my favorite)) is high, but then you can print all the parts you want, and reuse the motors and electronics. For instance the GoPro Hero 3 "upgrade kit" would cost you €0.35. You can't beat that
Maybe if you are member of a quadcopter club or R/C model airplance club, you could convince the club to invest in a 3D printer for printing other spare parts as well. Custom motor mounts, rudder horns, you name it.

For those of you stuck with a "GoodLuckBuy" or "GoodLuckSell" cheapo gimbal. I did a version for the motors and controller board: http://www.thingiverse.com/thing:374217
Since the motors are 50g and really crappy, I destroyed one of mine months ago, so I can't really test the gains etc., but give it a try if you so desire

So I've never torn apart, let alone built a gimbal before... but this is getting really intriguing and I'm just about willing to try.
DKDarkness... earlier you said you were spec'ing the print to utilize the Alexmos 2D controller + extension board. But... isn't the extension board to add 3D?? Confused why you would need the extension board if the MotorPixie is 2D. Or am I thinking of something else entirely?
EDIT: nevermind about the parts list/motor specs... found them on the website.

Please don't hesitate to ask any questions regarding the build, if you are at all in doubt
Be sure to order a Turnigy 2804-210Kv Brushless Gimbal Motor, if you are ordering from Hobbyking.com, you might need it in the future: viewtopic.php?f=7&t=20064

Geert decided that a 2D gimbal and a 3D gimbal are the same, and closed the MotorPixie 3D thread.
WTF IS GOING ON WITH GEERT?!?!?!

Just uploaded the revised MotorPixie 2D gimbal: http://www.thingiverse.com/thing:397579
I have tried to align the 2D edition with the 3D edition. This means you can print and build the 2D edition, and once you decide to want to try the 3D edition, you can reuse some of the parts, and all of the electronics. The common parts are:
Printed parts:
FC200 enclosure (GoPro enclosure)
FC200 enclosure screw
FC200 IMU case
Pitch arm
Body dampener plate / addon plate
Electronics and misc:
BaseCam controller board (in case you use a Goodluckbuy controller, you'll need a BaseCam for the 3D version)
IMU
2x Turnigy 2206-140Kv gimbal motors
8x M3x8 hex screws
8x M2x6 hex screws
8x M2 (4.8x0.3mm) washers
2x M3x20 nylon screws
4x M3x16 screw
1x 3.5mm female 4 pole jack
1x 3.5mm male 4 pole jack with wires (90 degree angle)
1x 50mm 1 pin wire (pitch control)
6x rubber dampeners (50g/each)
3x small white zip ties
To upgrade to 3D you'll need:
3D base plate
YAW arm
1x Turnigy 2804-210Kv gimbal motor
BaseCam controller case
YAW axis extension board (and connecting leads)
4x M3x8 hex screws
4x M2x6 hex screws
4x M2 (4.8x0.3mm) washers

Hi,
Is there any chance you can add in a stp or iges of the model?
I use solidworks so might tweak/personalise the parts. So if you are able to supply solidworks parts/assemblies that would be even more awesome!
Also I remember seeing a wiring diagram somewhere, but can't seem to locate it. Are you able to re-post?
Edit - Found it on your website! https://sites.google.com/site/motorpixi ... /Resources
Cheers
Rob.
PS. Happy if you want to keep the source protected and not release these...

Thanks! DK. Bummer about the call from "company who shall not be named". You must be such a threat to them...Nuts. I have had a similar cease and desist call request. When I challenged their trademark, it turned out that my logo was created before theirs, and although I did not trademark it at the time, the "prior art" allowed me full use and protection against the company who tried to bury me! They eventually changed their logo. I still have the logo, but the company no longer trades.
Cheers
Rob.
