"Hello George,I have a question for you, when are you planning to post the firmware? I'm interested to know if your firmware is using Kalman filter or DCM algorithm and how it is integrated into your application. Regards."

Juan Gomez replied to Kevin C's discussion Need advice on parts"well, definitely all this will work together!There are other systems to attach a prop, for example the KA20-22L. "
Juan Gomez replied to Kevin C's discussion Need advice on parts"Hi Kevin,Personaly, I don't like the prop saver system, will give you a lot of vibration problems! But... The motor by its own is a good one. this is my opinion.

ThomasB said… Hi Juan,
Thanks for the schematic ( I'm working with eagle too, so it was easy to look at).
Interesting that you are using levelshifter for the ESC's, my turnigy esc get their PWM with 3,3 V and they are working nice with it (Hobbyking SS30/25A too) , but your way might be the more correct way to do :)
With the XBEE module you should have a look with your 3,3 V power supply. Maybe you will get some peaks on it, which could disturb the IMU.
Your pressure sensor is connected to the AD input of your cpu (10 Bit resolution).
With an OpAmp you could increase the resolution.
Here two examples (not the same sensor, but good to show what I mean :)

By the way, working without jtag can be very frustrating. Which development tool you are using? I'm working with eclipse and gcc. Not nice to get in, but after some time (and many forum searches) it works well.
regards
Thomas

A ver quién de los dos termina su heli antes...

Iré subiendo por aquí los diferentes avances que vaya haciendo, así como lo hecho hasta ahora.

FELIZ AÑO!!!
Sí, es normal. La Matriz DCM tiene que tener modulo 1 en cada fila, y es lo que haces con la renormalización. Se inicia con una matriz unidad porque es la matriz más simple que cumple con los criterios de DCM, con el tiempo, efectivamente, la matriz se va tornando en lago muy distinto, no hay problema en eso.

Sí, ese código DCM debería de funcionar perfectamente. Por otro lado, lo que me comentas suena bastante raro... Yo lo que solía hacer, es quitar el giro del DCM, y ponerlo a cero (el vector del giro). Y entonces ver si los correctores, tanto el acelerómetro como el magnetómetro corregían bien y como debían. Mira así si el magnetómetro está funcionando bien.
Nunca me he encontrado con lo que me comentas... ¿Puede ser que tengas metales cerca y lo esté magnetizando??

Sorry for this silly question, but where is the code repository?

My QuaXCopter Project.

Hi Everyone.
I've been working on my Quadrotor project for one year. My last attempt was not good enough to fly. The control board worked well, but... i had problem with the frame. The frame was not enough rigid to absorb the mechanical vibrations coming from the motors. So, the IMU reported inaccurate data. Knowing all these errors, i flew my Quadcopter just some centimeters above ground without success.
Some months later, I decided to give the project…

Contests
Season Two of the Trust Time Trial (T3) Contest has now begun. The fourth round is an accuracy round for multicopters, which requires contestants to fly a cube. The deadline is April 14th.A list of all T3 contests is here.
