I hope you guys enjoy and benefits from my contents. FPV drone is super fun but not quite easy to begin with. Especially, it costs a lot overtime! I always try to find new ways to lower the cost and I want to share what I know. I also create 'how to' content for FPV. And of course I love flying so there are my flight footages from time to time. I do appreciate every single watch, like, subscribe to my channel and especially my channel's members. Thank you so much for your support!🤗 With the supports, I can continuously improve my contents.

I'm most likely wrong here, but it looks like your diagram actually increases ground loops? I thought by grounding each component to one source (in your case the BEC) you would create a star of ground paths, not loops. As an alternative, could you just add one ground wire from BEC to OSD? Thanks for the vid
พี่ครับพี่ช่วยอธิบายตัวระบบส่งภาพ OPENIPC หน่อยจะได้ไหมครับอยากรู้ว่ามันเป็นระบบมันเหมือนพวก O3 Air Unit หรือเปล่าผมเห็นคลิปที่เขาทำออกมา มันน่าสนใจเมื่อเทียบราคากันแล้ว ต่างกันเยอะอยู่นะ ขอบคุณล่วงหน้าครับ😊😊
You obviously have no clue about batteries because if you do not charge them to 4.2 V they are not full until they reach 4.2v and the discharge should be set at 3 V So you just wasted everybody's time.
The video is quite long but have you really watch it? The explaination is there. Not every charger has Li-Ion mode with 4.2V max charge. Not every charger has min discharge at 2.5V (Yes, if you want to really test a Li-Ion the min is 2.5v not 3v). Most RC chargers are max out at 4.15v in Li-Ion mode. You can use Lipo mode to charge it up to 4.2v/cell but the charging routine is not designed for Li-Ion. My charger has Li-Ion min discharge voltage at 3.4v. You can save your own time by reading the manufacturer specification before reaching out to a consumer testing on his/her bench to find out how is the Li-Ion he/she actually got. The purpose of this video is if the Li-Ion on the consumer's end has similar performance to the manufacturer spec sheet or not. Thus the testing equipment are different (manufacturer's equipment vs individual equupment). That is why we have to aware of the different of the testing environments and speculate from that deviation.
Interesting. My FPV video is OK, but could be better, so I was wondering if I could improve it with a common ground bus. Yours was the first and I think only video that came up with my search for "fpv ground loop" A common ground bus is essentially a "bar" with a ground wire from each component - you see them a lot in ham radio shacks (I'm a "foundation" what in the US would be a "technician" level ham). It sounds like it might be worth while. I'm thinking - and at this stage only thinking/researching - about taking some quite thin copper tube that I have from scale modelling and sticking a length of it along the bottom plate of my frame (if I can find a path) or the top plate (if I can't find a bottom plate path) and attaching it with double sided tape, and then attaching a ground wire from every thing including my FPV antenna (I don't think my soldeing skills are up to doing with with mt RX antennas ipex connector).
Having a common ground bus would be great. The challenge is the tight and complex space in the drone. I am building a complicate drone and found that the 'Matek servo PDB' helps in terms of both power regulation and sharing of common ground. If you can create the common ground bus for the FPV drone it would certainly be a new idea.
