A very strange problem...

Post by cestb »

Hi,

may be, which is causing all my trouble but i could not explain it for now.

I took pictures and movie to show you what happens. I amplifies a bit the phenomenon but it happens one time on 2 or 3 when i put my plastic canopy. It doesnt happen if i don't put it (you will see in the movie that i could touch everything with my finger without causing a problem). Canopy doesn't touch anything on the board but it is very close to the allinone when it's in place.

The movie to show what is happen :

When it happens, debug 2 increase or decrease a lot (increase in this test), debug 1 seems to stay as it is.

Gyros go crazy during a few second. In the gui, artificial horizon goes crazy and you see the result on gimbal.

After it returns to normal, the gui is like that :

Any idea, static electricity ?

Do you have everything connected with common ground?
Otherwise you can get strange glitches.
