Hey Guys,
Take a look at this snap shot from the quadrino setup tool. There is no Acc Defined. I entered the serial number off my board for sensor configuration. Maybe this is why my blue LED is not coming on when I enable ACC. I am not getting any I2C errors. And if the ACC is not coming on, the quad is hovering vary stable. Only been able to test in my basement.

I believe I have REV1E Board, I think this should be defined #MPU6050 //combo + ACC instead of this # MPU6050, under the /*I2C gyroscope*/ section.

Have you tried to define ITG3200 instead if not sure what gyro was inside?

The ACC pad on my board is not populated, so this means that the board uses the MPU6050 for both Gyro and ACC. When I look at the defines in the picture I just posted it bugs me that the #define MPU6050 // combo + ACC is commented out. However if you go into the GUI there are no I2C errors and when the quad is moved the ACC readings change. I dont really want to dig into the audrino code very deep. I could see the program reading the sensor but not using the data since it is not defined. I am not sure what to do.
Can a person change the defines inside the Quadrino Programing tool or do you have to load up the sketch?

You can change everything in config.h and hit upload, when exit it, don't save changes to keep it as before..

If your using the Quadrino tool you can change how your the options you use such as picking the different sensors.

Now if you have a MPU 6050 board you don't have an actual acc chip.
The MPU 6050 is capable of doing both job.
It is a unique chip.

Here is my MPU 6050 config. h for arduino.

Hey guys,
Thanks for the help, Doc thanks for the help and posting your config.h file, I still think that it needs changed in the quadrino tool but I really don't know whether it was or was not working before. All I know is that the little blue light was not coming on, I don't know what actually turns that light on, and it doesn't really matter either, but now it does thanks to you guys. That little blue light gives me a little comfort because I am not the best pilot, but I know when that light is on I can recover.

I think the MPU is a 6 to 9 axis chip with the gyro and acc both built into the silicon die, I think the last 3 axis come from the ability of being able to hook an external 3 axis magnetometer to it. Its a pretty sweet chip. It would be even better if the company would let all the docs out from what I hear.

Still have not had a chance to take the quad out and test but initially everything looks good in the GUI

Is there going to be a webex tomorrow, I finally got a headset today?
Thanks Again

I have some other ideals that I am holding on to!
My buddy is thinking about getting a CNC router.
He also is a Master Machineist. He has vowed to help me design an all Doctor Audio frame.
If he gets the one they may sell him at work!

Really, I want to design rotating motor and self folding quad!
There is one for you designers out there.
Lets see what you guys come up with.
All arms have to be able to adjust the angle of attack.
Also at least two arms have to fold to make it more compact.
Like fit in a regular size duffle bag!
Good to know

Overheating BEC (5V/2A) Turnigy Basic 18A ESC

Hey Shawn, mark_q, Dr Audio: Thanks for your replies!

Shawn, that was a good idea, that I might be overpowering the BEC with a 4S battery.

But I'm using just a 3S battery, as in a std WiteSpy Quadrino. Still, having this discussion helped, because it never would have occurred to me that the BEC in the Turnigy Basic 18A ESC (just as do most BECs) uses a simple linear voltage regulator -- not the fancy switching type. Now I know!

Interestingly though, a linear VReg with a 3S battery would have to dump around 2.2 watts of wasted power as heat, when dropping 12V down to the 4.75V my BEC emits. That doesn't seem that much more than the 3.3 watts a 4S would force it to dissipate; especially when you consider this ESC's BEC can (supposedly) handle 2A, or almost 16 watts!

Since nobody else seems to have a problem with their BEC overheating, I either have an undiagnosed failure, or have done something stupider than usual.

If I ever figure it out, I'll let you all know. Unless I did something really really stupid. In that case, I'll just smile and try to look innocent.


ESC: Electronic Speed Controller
BEC: Battery Eliminator Circuit (often available on an ESC)
