Moving to a better platform

posted Nov 19, 2014, 12:03 AM by MotorPixie Gimbals

The MotorPixie is moving to another platform. The closed DJI Phantom platform will be replaced with more open platforms. The platform I have chosen for now is the RCExplorer Tricopter. This platform is more stable, easier to maintain and repair, cheaper to build and very open. The frame can be found at RCExplorer.se and the the parts I have created for this platform can be found at Thingiverse. Find them amongst my designs.

Find it and all the necessary instructions on Thingiverse!

Wish I could say more :-)

No further development on 3D MotorPixie gimbal in the near future

After playing around with the 3D version for some time, and not really getting the results in extreme angles I hoped for, I was about to give up. Looking for solutions I came across a professional youtube video explaining the wonders of the new 32 bit version of the AlexMos (Basecam electronics) 3D controller. Until now I have been using the 8 bit basecam controller with 3rd axis add-on board.

In short: The 8 bit basecam controller does not support the extreme angles one would need to use it on a quadcopter. The 32 bit version should be able to do so. Am I going to test this? No. The cheapest non-3D, certified basecam controller is $80 2D Basecam controller which comes with non-standard connectors. Keep in mind, the hardware is not licensed, it is the basecam bootloader (which basecam electronics has stopped supporting, no new versions since 2.40b7) that is licensed. In comparison the equivalent Chinese knock-off is $24 2D Chinese knock-off controller that comes with standard connectors. Am I going to pay 300% extra for a bootloader that is no longer supported? No, not again. Am I going to pay $200 for the 32 bit version that supports 3D natively (maybe?) but does not yet come in the "tiny" version I want for my projects? I am all for "intellectual property" and having to make money to do R&D, but I am not (again) going to pay excessive amounts of money to be able to create another version of my gimbal, only to force others to do the same in order to build one.

I might look into the BruGi project, and how to use this open source bootloader on the cheap Chinese hardware. I might even donate some money in order to support it.

I short: I am not going to do any more development on the 3D version in the near future. Buy a ready made 3D gimbal if you want one.

Heavy version for the Turnigy 2804-210Kv coming up...

posted Aug 1, 2014, 12:11 PM by MotorPixie Gimbals

I am currently working on a MotorPixie 2D version that uses the bigger Turnigy 2804-210Kv gimbal motors. The gimbal will be heavy. 250+ grams. Limited flight times, but the added mass will be able to counter less than perfectly balanced props and motors (beat down Phantom).

It is more out of necessity than anything else, since my Phantom 2 Vision has taken quite a beating in testing the different designs. I simply refuse to spend any more money on DJI products, so when the P2V finally breaks, I will most likely turn to my newfound love, the Bixler 2 fixed wing model. I time I maybe building a quad from scratch.

A Black Edition for the Black Edition :-)

Remember you can print the MotorPixie 2D gimbal in any color filament you can get your hands on :-)
Here printed in black ABS for the GoPro Hero 3 Black Edition. The IMU now can be moved from FC200 enclosure to GoPro enclosure and back without reconfiguring the controller.

A lot of prototypes!

As we move closer to the final product, it is time to reflect on the development process :-) All the material used for prototypes is actually less expensive than one mistake on the wiring! 1kg of filament costs around $30, whereas one fried DJI Phantom 2 Vision controller mainboard will set you back by $99!
A lot of prototypes

MotorPixie 2D gimbal aligned with 3D design - Parts list included

posted Jul 17, 2014, 2:03 PM by MotorPixie Gimbals

The design of the MotorPixie 2D gimbal has now been aligned with the 3D version. This allows you to start with the 2D version, and at a later time upgrade it to the 3D version, reusing the electronics and many of the 3D printed parts. Find the aligned 2D version on Thingiverse along with the detailed parts list and specification.

True colors...

Last night a representative from the company that must not be named, contacted me via phantompilots.com and insisted I had stolen his design (the silhouette of a phantom quad seen from above) and insisted I remove it. Whereas I am reluctant to to change my logo, the quad with the all seeing eye of Sauron, I don't want to be associated in any way with the company that must not be named. Therefore I have changed the MotorPixie logo. You would think that the company that must not be named had better things to do with their time, but no. They have indeed showed their true colors.
