Brushless motor testing without LC meter.

In this longish video I show you how to test a brushless motor from a miniquad with a drill and multimeter.
No special parts required.
Also - Oscilloscope stuff!

Thank you so much for this information. Been blowing esc's and couldn't figure out why. Gonna test all mine tomorrow.

i guess im randomly asking but does anyone know a tool to get back into an instagram account..? I stupidly forgot my password. I appreciate any assistance you can give me!

@Marcos Rene Instablaster ;)

[@marcosrene4446]

@Bruno Case thanks so much for your reply. I found the site through google and Im in the hacking process atm. I see it takes a while so I will reply here later with my results.

[@marcosrene4446]

@Bruno Case it did the trick and I now got access to my account again. I'm so happy:D Thanks so much, you saved my account !

[@brunocase7041]

@Marcos Rene No problem :D

[@instalemong6498]

Really informative and simple. Thanks

Would like to see the results off a faulty motor on the Oscilloscope.

[@NilsRohwer]

On the way Michael!

You can scoot the alligator clips up so the can't short or put pc tape on middle one. Good vid!

[@chrisfeyerchak]

Connecting the scope probe ground clips to nodes that are at different potentials (different voltages) can cause problems and possibly fry stuff.

THANK YOU VERY MUCH.

[@zzathros]

clicked like but i also wished you had shown the bad motor on the O'scope

[@NilsRohwer]

Hey Zachary, there is a newer video showing the faulty one on my channel. Cheers!

[@ISLAMguidanceful]

i have the same oscilloscope, i tried exactly what you did but i got a lot of jitter in my signal, can you please tell me how you got such a clear signal

[@NilsRohwer]

Will clear that up in the next video. Thanks for watching!

[@ISLAMguidanceful]

That would be awesome man, cause iam trying to use the oscilloscope for school too.

[@PosBridge]

7:29 mind blown... can you not rewind the busted motor?

[@klopossa2]

Yes..

[@Novous]

Oh yeah, it's way easier to not spend $20 on an LC meter and just use a $2000 drill press! Personally, I use a 3 million dollar electron microscope sitting in my basement since most people have one.
