Simple AlexMos brushless gimbal from Viacopter
Pictures added of production prototype VectorDD gimbal for GoPro and a first prototype gimbal for mirrorless cam and small to medium DLSR.
More controllers will arrive on moday 25/3 at Viacopter
I decided to take out a thread about the Alexmos gimbal system that will soon be launched from ViaCopter and Flyduino
Dont ask for preorders or lists - we are serious people, and we just dont begin to sell things that we dont have in stock Availability will be announced in good time before they go on sale.
Here are the videos:
The gimbal is adjustable, so it can be balanced perfectly. It is also designed to put the lens on the exact center of the roll axis - something that is very important for aerial videography. Gimbal design by SebastianJ
Final production version with USB and IMU for camera:
Price for the controller and IMU is 110 Euro.
GoPro Gimbal for HeroHD and GoPro2 will be launched first. Also of course version for GoPro3. We dont have an ETA on those, since it depends on how fast our metalworking factory can produce them for us. We are shooting for them to be available inside 3-4 weeks, but its not a promise.
GoPro version is 268 grams with camera and controller. GoPro3 version will be slightly lighter.
We are currently designing gimbal for Compact and System cameras like HX9, Nex 5/5N/7 and EOS M.
Later will come versions for DSLR and Camcorders like CX730 and CX760.
Feel free to ask questions or post suggestions.

Like everyone else in the MR community the AutoQuad Team was seeking for a solution for a top notch gimbal control, though the internal camera stabilization of the AQ6 worked pretty well even with cheap gimbal/servo combos.
New Alexmos/BaseCam 32bit 3axis Brushless Gimbal Controller Preorder!
Available at Viacopter and Flyduino
This video shows the complete setup and tuning process, examplary connected to an AutoQuad FC
Thanx to the SBGC project by Alex Moskalenko and the efforts of AQ Team members like Jussi (ViaCopter), Paul (Flyduino), Felix (famous Flyduino NanoWii and UltraESC design) and SebastianJ (Gimbal design) we'll soon have what many desire: an affordable, simple but effective solution for Multirotors - and any vehicle you can think of attaching it to.
I'll try to collect some more info about Alexmos' SimpleBGC as we go...
Here you can find more info on the VectorDD / Alexmos brushless gimbal

Here's a nice tutorial, based on Fabien's aka Bricobrac info:

Before you plug in the board for the first time, get the Silab USB COM Port drivers for windows
Depending on your board you might need drivers by FTDI insteand.

Connection diagram and functions:
As you can see, Alex' solution is a separate controller with special firmware that can be connected externally to override the channels by both the flight controller and the receiver. The proto has a separate IMU.
As Jussi already mentioned Felix' design will include a USB connector and a separate IMU.
So you can easily connect it to the GUI for basic settings and control.

How to connect an analog joystick like the PS2 ones to your controller
- close J1 (JP1 or L1 on some boards) to provide 5V to the RC channels
- connect GND/5V of the joystick
- connect the VRx and VRy pins to RCpitch and RCroll
- assign the desired ports (in most cases pitch & yaw) in the RC settings
- reboot your controller

Since Jussi posted the video for the first time people keep banging at our doors.
So there was an urge need to canalize the info - not having to tell everyone the same again and again...

PLEASE include a ramping feature on the tilt axis (pan axis when available). If you look at Zen videos you will notice pilot control on the pan and tilt axis are somewhat robotic. A ramping feature will smooth this movement.

Count me in! Already reserved the bucks for it
Do you have a estimation what the motors will cost?
Great work guy's. I'm really looking forward to it.
