Found this blogpost about building a filter to manage current spikes from the battery, does anyone has experience with them?? it would be nice since it uses common parts widely available https://oscarliang.com/power-filter-video-transmitter-fpv-camera/
#Have a 12v VTX (video transmitter) but the FC (flight controller) only outputs 9V.

what vtx is it
tulip ridge
video transmitter, i will write in without acronims
Have a 12v (operating voltage) VTX (video transmitter) but the FC (flight control) only outputs 9V.

How is the system wired in general?
Is this a drone with analog OSD chip and whatnot?
Just a VTX/Cam slapped on a different setup?
Note that the liang article you have is for many modern hardware theese days out of date tech.
How to do stuff with what was available in 2014 is vastly different now if you have 2025 hardware

its a drone that im building from parts,

thanks this is good advice in general, ill take it into account.

If you send us a parts list and pictures we can assist better.

""Working voltage: DC7V-36V"" but operating voltage is 12V so it SHOULD accept 9v,
i dont understand how it can operates at 12 v when it receives 9v and got confused
ok ill just try it when it arrives at 50% power
lunar nexus
Oh yeah if it takes 7v as a minimum then using the built in 9v the FC gives is fine and probably the cleanest way to wire it in terms of electrical noise.

Never power up any transmitter equipment of any kind without an antenna attached fully and properly.
Running a transmitter without an antenna will damage it very bad and quite quickly as well.

Where do you see the operating voltage
Again, what video transmitter is it?
Because the 7-36v means it will work at 9v with no problems
tulip ridge
yes, i read the operating voltage 12v and panicked lmao, need a coffe. still learned about how to build a filter so it wasnt all wasted
oh, its working CURRENT
spark hemlock
I’d recommend one from Rush, TBS, Flywoo, much less likely to have noise than some no-name vtx
Especially at that high power level
tulip ridge
yes, if a build another one ill use better parts, this is the first build so i went as cheap as posisble
