Thank god I sort of solved the issue. The problem is.... I'm getting horizontal black lines on the video when the motor spins up. The faster the motor spins, the worse the black lines gets. I know what some of you are thinking already. Here's my electronic setup just to clarify: I have a pdb with a good quality low esr cap. VTX is powered by a 9v regulator filtered by an LC Filter Camera is powered by 5v from vtx If you ask me the above mentioned is already overkill for cleaning video noise. Anyway I have 2 cameras I tried this on, and they are both hs1190 v1. I was about to give up until I changed the camera to an old school cmos camera and all of a sudden all video noise is gone! It almost seems like the internal regulator for the 1190 cameras are messed up. Did anyone else experience this? Does anyone know if I can solder a cap on the camera's board to remove motor noise? Are my 2 cameras just messed up? Cheers and Thanks! • Posts: 2,416 Threads: 51 Likes Received: 1,861 in 1,175 posts Likes Given: 3,315 Joined: Mar 2016 Reputation: 74 I've read that this can be caused by grounding issues. They should be grounded to same place.

How you route and manage the wiring from the camera to the OSD and to the VTX is really important when it comes to minimising the chance of them picking up noise. While capacitors and even LC filters help to an extent, you can't get away from the fact that there are wires in your quad that carry large currents that vary rapidly in both magnitude and frequency. That creates powerful magnetic fields which can easily affect nearby wires. Your average quad is probably one of the most electrically hostile environments there is and I'm surprised every time I manage to build one with a clean video signal!

Is I mentioned earlier I simply replaced my camera and everything is good. No more noise. It's just strange that the noise only happens when using an hs1190 v001 camera. When I was doing the testing all the bits are outside, none of the components were close to each other. I was just wondering if this was a known issue that these hs1190 cameras have. • Posts: 2,286 Threads: 38 Likes Received: 1,527 in 995 posts Likes Given: 1,881 Joined: Apr 2016 Reputation: 72 (19-Apr-2017, 10:59 PM)trojanGoat Wrote: Hey Guys, I no longer have it hooked up.

Ah, sorry, I obviously didn't read your post properly. Check the actual voltage that your VTX is providing on the 5V output with your multimeter. If it's not at least 5V while the HS1190 is plugged in, it could result in a marginal supply for the camera. Also, the camera will happily run on the 9V from your regulator, so you might like to try powering it from there instead. • Posts: 947 Threads: 66 Likes Received: 350 in 248 posts Likes Given: 164 Joined: Apr 2016 Reputation: 34 21-Apr-2017, 09:15 PM (This post was last modified: 21-Apr-2017, 09:16 PM by oyvinla.) Black lines could be a loose ccd sensor. Try to knock the camera when the quad is not armed and see if the vibrations from the knocking will bring out the black lines • Posts: 328 Threads: 76 Likes Received: 191 in 85 posts Likes Given: 39 Joined: Jan 2016 Reputation: 16 Yes those could be it. Sometimes when I spin up the motor the black lines will get worse or I will get scrambled image, then it might go away. Is there a way to fix this? • Posts: 947 Threads: 66 Likes Received: 350 in 248 posts Likes Given: 164 Joined: Apr 2016 Reputation: 34 Search for "Oscar liang glue ccd" and you'll find some i formation (I'm on a phone and didn't bother with searching for you ) I fixed a couple of them by reflowing the solder by heating each pin with the iron • Posts: 5,315 Threads: 672 Likes Received: 3,155 in 1,743 posts Likes Given: 2,030 Joined: Jan 2016 Reputation: 139 Open the FPV camera and see if the sensor and crystal cylinder are falling off? example: https://oscarliang.com/hot-glue-runcam-swift-camera/ Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 Hmm now Im curious about my Swift2.
