Here is an active buzzer. I haven't tested it myself, so I know nothing about it except the information on the web page:

That sounds like the way i would go.

Currentsensing LC filtered PDB -> good Flightcontroller -> fitting OSD

I guess i will try the Holybro PDBOSD_v1.2 u posted



Don't worry, at home i have Weller WSD81 Soldering station and at work I have the Weller WXR-3 and I can also use a Spectrum Analyzer that costs around 70.000€ to check the antennas and transmitters ... all stuff like that. So don't worry about the equipment I can use, we are using high grade here since we are working with radio communcation equipment. Most of the Stuff is Rhode & Schwarz, Wil'Tek, Tectronix ... Big Grin I really love the gear we have.

Nice! Sounds like you got the equipment in place Big Grin

Creme de la creme Big Grin

God damn i am utterly retarded. I am still stuck looking for a suitable PDB.

What PDBs would you recommend. Right now i would go for one with filtering and current sensing resistor. What would you recommend. I have the feeling i am running in a circle. Saying i found something without reading it entirely... and then realizing it's not what i am looking for.

I want to hook that up to a Betaflight controller and that to a fitting OSD.

At the moment i'm placing this PDB on my quad, i like the position of the solder pads on the corners, it has a current sensor max 140A and 12V and 5V output.
I don't use the socket, i'm using some wire between the PDB and the lipo, this because the cable from the lipo is to short to reach the connector on the PDB and i think it's more crash ressistant.

Omg thank u Ikkuh, i just remembered that this board was posted before! I really forgot about it -.- Like i said, i feel like i am walking in circles

But i am set now on this one. I gonna do some research now, which Betaflight controller i gonna chose and what OSD to add there. Thank u

You are welcome Apicalis, i'm glad i could help you with the PDB. Sometimes you have just order the stuff you have selected and going to build. After that you can still upgrade some parts, otherwise you will keep finding better stuff or with more features, but you are still not building and flying.

I have also bought a frame that is not very solid so i got a lot of vibrations through the frame, also i can't update my ESC's through my FC, but that isn't a big deal because i can fly and i know it for the next time to check for that stuff. And you don't update your ESC settings so much thus it isn't a very big problem.

Yeah i am already expecting to be changing some components within a few months. There is always new amazing stuff coming out!

But i really wanna make sure the first setup is something that fits all my needs. After that, changes of course can be made Smile

Right now i think i would get the XracerF303 V3.1 or the Lumenier Lux V2 both with Betaflight. Am I understanding it correctly that they both can handle I-Bus and i just have to set it up on the FC that I am using that particular protocol?
Am i seeing this correct that there is no current sensing connector on the FC Xracer? Is it necessary to have it on the FC or can i directly hook the current sense output of the PDB to the OSD? (which would the make the wiring a bit more messy i guess)

as long as the FC has serial ports, you can use ibus. It is the firmware (betaflight/cleanflight etc) that decides if you can use it or not.

The easiest and less messy way to connect an osd (like micro minimosd) is to use the serial connection to the FC and connect the current and battery voltage directly to the FC and let the FC take care of it. Now the osd will get all the data it needs from the FC once you set it up in mwosd gui.

Thank you, now i am set on the Lumenier Lux V2, i find the PCB design more attractive anyway Big Grin Time to post my updated Component list on the bottom of this reply ^^

Which VTX should I go for? I wanna have one where i can adjust the power to the flightsituation, also I want to have it separated from the OSD. I do like the ImmersionRC Tramp HV or do you think i should go for something cheaper?

Remote TX/RX: Flysky FS-i6X 2.4GHz 10CH AFHDS 2A RC Transmitter With X6B i-BUS Receiver
Frame: MartianⅡ 220
Flight Controller: Lumenier Lux V2
ESCs: Racestar RS30A V2
Motors: RCX RS2206 V2 2400kv
LiPo:
FPV CAM: Runcam Swift or HS1177
Video TX: ImmersionRC Tramp HV
Antenna:
OSD:
PDB: Realacc/Matek PDB-XPW
Recording CAM: GoPro Hero 3 Black Edition (got one lying around)

I'm using an Eachine ET526 which has worked great so far with range and picture. Two of them have even been submerged in water while powered and still works good.

The negative parts I have noticed is:
- It is a 2mm thicker than normal due to a heatsink on the vtx.
- You have to doubleclick the button every time you power up in order to turn it on (could be a good thing if you need to power up your quad when there are other people flying).
- It looks like the VTX is spamming other frequencies or is outputing more power than 600mW. I fly with a friend which uses an immersion 800mW VTX of some kind and a Laforge diversity module and many times when I take off, land or do a flyby, he complains that he looses his picture. It is not consistent, so when we try to test the problem, we can't seem to provoke it. This problem mostly occurs when running my VTX on 600mW. I am using Raceband 1 and he is on Raceband 8.

The TBS triumph antenna works great and I use it on my quad. On my goggles, I use an aomway antenna, which has been giving me better reception than the TBS triumph for some reason. I also use an immersion patch antenna paired with a realacc RX5808 diversity receiver flashed with custom firmware developed by GC9N on RCforum.

I have ordered a Eachine TX526 which is dead cheap to test, but keep in mind that it is RP-SMA connector on it.

From my experience, there isn't much difference in picture quality and signal strenght between cheap and expensive VTX's. The most important thing is to have good quality antennas.

But there are some nice features on the new immersion VTX where you can control it from the Betaflight OSD, but I don't know much about it.

Hmm I will go with the Immersion one, even though it's twice the cost. 

Yeah high frequency signals are always influenced by many things. The VTX PCB Layout alone can shift the resonance frequency. That's why i am interested to actually measure it with our high quality equipment where i can actually see where the resonance frequency has shifted and can actually change things to get it perfect if necessary. So I am not surprised at all that the Receiver on the Goggles works better with other antennas.

But as you said and as it was posted before in this thread (probably by you xD ) i will buy 4 Aomway Cloverleaf antennas so i have some spare in case of a nasty crash. If I am correct I would need to get SMA Antennas, is that correct? The description on Banggood exactly says SMA ... but ... you know ... it's a chinese page so I don't really trust it ^^

Does anybody know if this OSD can be connected to my planned setup and if it can show powerconsumption not only voltage? 


Here is my current list with prices
   
[EDIT: Links not working, don't know why. Are the Banggood links blocked in the hyperlinks settings?]

Blue Aomway antenna is SMA and red is RP-SMA if i remember correctly. It looks like the tramp uses a SMA pigtail according to the immersion website.

If it is the micro minimosd they sell for about 7 dollars or so, it will work, but you will have to get an FTDI adapter as well for flashing mwosd firmware to it.

oyvinla don't worry. I got several Serial programmers because I do a lot of arduino programming. Ty for the infos Big Grin


Well this means i got almost all my quad components! I updated my list again of course (all prices in €)

   

Missing now are:

- Nylon Standoffs and nuts
- Battery Straps
- Battery charger
- 4S Batterys

Did i leave anything out and you guys have any recommendations regarding chargers and batterys?

Regarding chargers, depends wether you maybe already have a 12V or 24V power supply so you could buy one without integrated transformer?
