i think you have to raise the Power and maybe the I, to get rid of the vibes. You can see the vibes on the gimbal?

Any ideas? Has anyone else had this issue?

How can I check which version of Firmware is on my board?

I always get the answer "upload failed" while using xloader v1.00.
Anyone an idea?

Look at the upper left corner of the GUI, it should state which version is loaded. Doesn't matter which GUI you use it will show the FW version...

It will always state "upload failed" this has been mentioned several times....

I designed and printed a compact gimbal, the "Minim Gimbal" for GP3.
It works beautifully, but when I point it down vertically it also goes nuts.
I think it's a limitation in the firmware.
Admittedly I haven't tried increasing the tilt range in the software, so maybe it's an end stop issue.

Cheers
Matt

Please help!
I have soldered the sensor plate and connected to my now AlexMos Board.
When I connect the board via USB to my Win7 Computer the board flashes green for a while then permanent.
When i start the GUI it Shows BoardVer. 0,0 and nothing happens. When i try to upload a new firmway, xloader says "upload failed". No idea, what to do.
When i shake the sensor board i cannot see any Feedback in the GUI.

Connection Problem or Driver problem for USB?

Clearly you have been unsuccessful at uploading the firmware to the board.
There's a few ways to upload firmware, have you tried the other apps?

"To upgrade firmware, download latest firmware (.hex file) and XLoader or AvrdudeR utility. Run utility, select COM port where controller is connected, and specify hex file to upload. Leave all other settings at default (baud is 115200, device is "SimpleBGC"). If device is restarted after upload - it means all done. Run GUI and check if firmware version has changed.

LINUX and MAC users: use avrdude to upload firmware. See command line parameters in XLoader/upload.bat."

Very nice clean design. Assume you 3D printed it yourself?

Now i tried with AVRDudeR. After a second it says flashing done but nothing happens.
Seems i have Problems with this USB Driver.

Where can I get some cheap vibration dampers? Preferably in the US.

Now i tried an other computer with Windows 8.
Firmware update with xloader started and seemed to work, because of blinking Controller. But it stills blinks very fast (green). I disconnected the board from USB and after reconnecting it still is blinking green very fast - ??
Anyone an idea?

I have my limits set at 90 deg each way on both pitch and roll. I have had no issues with the gimbal twitching at all when I go to vertical.

Read this post....

You have to install the drivers, I messed around for some time like you and then installed/reinstalled the drivers from the link in this post and everything was smooth from there...

Thanks to everyone for the response.

I am seeing this vibration when not in flight. Ie on the bench.

I assume my gimbal may not be 100% in line so I am ensuring it is all perfect now.

I have read that askman has the same issues.

When I point the camera straight down on the bench I hear a real "moaning" noise that goes louder and louder.

If I reduce my d down to 3 then it goes away and works perfet however that is too low for proper tilt stabilization in flight

I will post a video as soon as I get the gimbal back together.

Controllers will be available from thursday 14:00 CET at Viacopter and Flyduino.

We have revised the IMU a bit to include a JST XH connector and matching cable.
