Wet Tiny Whoop - Beebrain v1.2


#1

Crashed my whoop into a puddle. Power did not go out. Camera still works but i cannot bind with transmitter. Tried to bind but red light just blinks fast and does not go steady. Any recommendations for a fix?


#2

Put the FC in some uncooked rice to try to pull the moisture out. I would also reset it in BetaFlight


#3

99% Denatured Alcohol will remove the water while cleaning up any accumulated gook and then magically evaporate


#4

Submerged it under uncooked rice overnight and tried again. Reset, recalibrated accelerometer. Still no go.


#5

how do i apply denatured alcohol? with a brush?


#6

After cleaning the board with denatured alcohol (used soft brush and wet the whole unit, then blow dried). I found this. There is a visible crack and it is a bit loose when i try to poke it.

Could this be my issue? What does this chip do?


#7

Good news guys! Powered it up and everything seems to be working again. Placed a tiny bit of hot glue on that crack and put it back together. Got it flying again. Thanks for all your suggestions!


#8

That’s the ticket! Glad you’re up and flying!

I believe the component in question is a coil, probably used for filtering power - cracked is not necessarily compromised. Hot glue or CA will take care of the crack (as you’ve done already)


#9

That’s an inductor, it doesn’t mind the core being cracked as long as the coil of wire inside is intact.
Good to hear that the board lives!

I just want to share this. I went back to the site where I crashed and finally got my shots. Thank you for all your help! Enjoy.

Good to hear it’s working again! There is something magic about water and electronics.

Couple days ago I gave a friend of mine an E010 to play with as a gift. Yesterday he comes up to me and proudly said he crashed it into the cats water bowl and it still works. So I was like, woah, you quickly removed the power and let it dry? You were lucky!

He was like: No, I quickly continued flying, I figured it would blow the water off! :joy:
He said it was fully submerged… lol

Applying a coat of Silicon modified conformal coating will weather proof your electronics , can be found off amazon for $14 a bottle. It dries on clear, shows up light neon blue in the black light lol

so if u end up whooping in a blacklight scenario and crash in someone’s beverage, it’ll even look as bad a$$ as the pilot flying it AND could fly away after shaking it off :slight_smile:

Also, @airzoink awesome whoop video with the crane. Music was chill!
