Hi Andy A great tutorial and excellent timing as I've just purchased another APM 2.8 which has the MinimOSD bundled with it. Interesting issue with the cloned power module. I already have a Genuine 3DR APM install in one of my fixed wings so I'll pay attention to the differences between the 3DR power module and the cloned version supplied with the latest APM2.8. The FrSky voltage sensors are very accurate but I have reservations about the 40Amp current sensor. I had one of these installed on my Hex and with a 3s 10400mAh battery my flight times dropped from 18mins to 7mins. I found that the voltage drop within the sensor exponentially increased as the device warmed up. Even though it's spec'd at 40Amp any current draw above 10Amp resulted in an excessive Voltage drop. Regards Nidge
+AndyRC So far I've not had any issues with the 3DR module. It tracks the Voltage and Current draw/used quite accurately. I'm sure you probably have but if not you do need to tell the system, via Mission Planner, that the module is installed along with the battery type and capacity. I've yet to install an FPV system on my APM equipped plane so I've been using the 433MHz radio telemetry link with my Android Phone (Droid Planner) to monitor all the onboard sensors and to create and execute Waypoint Missions. Your tutorial on the MinimOSD will be invaluable when I get round to fitting it, hopefully in the next week or so. Regards Nidge
Hi Andy, I appreciate this video was done awhile ago, but from memory and in general can you have only signal wire going into minim osd from camera and only signal wire going out to vtx without earth? Thats if you have powered both sides of the osd with pixhawk telemetry input. Cos I think i have read somewhere in arduplane regarding the pixhawk servo rails, you have to power the servo rail with a separate 5v or 6v supply but it's always recommended that you connect signal wire including ground to the servo railing regardless. Thanks for your efforts in general, my first ever question 😊
I have two of them and i also hve the new micro version i never tested though but i am pretty sure it will work great as the big sisters do lol That was a very detailed video my friend! Very impressive work :) Thanks for sharing and have a great new week
AndyRC It might possible, it's really small lol I will figure out when i will finally decide myself to use it probably on a new mini quad :) Enjoy your week
Hi Andy, nice one, as indeed it is a pain to get an OSD working properly with Pixhawk from my experience! One thing though regarding the voltage problem, did you calibrate properly your battery with a meter while at 75% thrust with inverted props, so you can play with your divider and come to a reading on MP close to the Meter reading? Also, if I may you mention you would perhaps go for the Frsky module directly from the battery; and was wondering what you were referring to Andy, please?
+FPV Cambodia yes It was calibrated under load in a previous episode and it doesnt work :( frsky sell their own telem module for battery voltage that plugs into the X8r and sends the telemetry to the taranis
I have a small issue, the video that the osd puts out from the fpv camera is very bright, overexposed. Barely can see anything. This doesn't happen when directly plugged into the vtx without the osd. Do you know what is wrong?
Off topic but have you done any videos on ezWifibroadcast, Andy? I need someone to show me how I can connect a pixhawk cube to the raspberry pi and have telemetry (compass, gps data, voltage etc etc) on the HDMI monitor. :( plenty of paragraphs saying it can be done but no step-by-step instructions anywhere.
Hi Andy; Nice one! I have a couple of these bloody Mavlink board without the jumper from 12 to 5 VDC removing the power to the intputs Video components. And never used them due top the risks of over heating, and disaster in-flight! I concentrated on your bypass hardware removing the component you properly showed (minute 17 Ich); but would like to know if there were some proper "how to" anywhere on the net, as I have not found it and gave up! I'd like to reuse these little Mavlink OSDs, as a few are here awaiting to work, in the drawer... Tks for your consideration, if I may; and cheers for such well done and to the point tutorials; once again! Cheers and Safe Flying!
+FPV Cambodia the problem with the mavlink is theres so many different versions of them. I only have the one in this vid. the best thing to do is search on goggle images to try and find your version to do the mod. as for the mod its self i just heated the component up with a soldering iron until it fell loose ensuring that non of the other components were touched.

Hi Andy Thanks for all these answers you have really helped me threw my quad I am ordering 1000kv motors will these lift a gimbal seing as you used 920kv Is there a big difference thanks
Hi Andy. Excellent channel and watching your thorough explanations and reasoning behind choosing the parts has made me confident enough to finally start building my own quad from scratch. :-) Where do you usually buy your stuff from if you need them fast? And are you on Twitter by chance? :-)
+LurifaxDK hi, i dont usually buy stuff fast, I get everything from china and wait. the price is just too high anywhere else. I would look at ebay if wanting to get stuff fast. im not on twitter just youtube for now
Hi Andy, you have a great series shaping up here. I am following your build and using it as a base for one that I have planned. Is the crius mavlink-osd the same one that you have (I can't post links here unfortunately)? I am trying to get by with as little soldering as possible. Also, in this setup, is it possible to get telemetry for both the radio and the fpv setup?
+Sarath Menon I'm not aware of that version of the osd. like I say there's a few versions. u will have to see what it's like when it turns up. yes the RX1 will work :-)
+Sarath Menon I'm not aware of that version of the osd. like I say there's a few versions. u will have to see what it's like when it turns up. yes the RX1 will work :-)
Thanks Andy. This is a bit confusing for me, so please bear with me. For me to use a phone as my primary monitor, what do I need? Any transmitter, and just the rx module, right?
Maybe a bit late but : MavLink doesn't work on every FlightController board. It works on a CC3D flashed in OpenPilot, but not CC3D flashed in Cleanflight MavLink also doesn't work on a SPRacing F3 board. Instead of Mavlink you have to use MW-OSD
hi andy Ur osd is reading voltage which is not stable Reading due to the input 5v of osd is not stable. as you may be knowing the analog reference is taken as reference voltage to calculate the battery voltage, current, etc. If u connect it to a another battery (1s) to power the osd then you would get a stable reading or just use a 9v battery and 5v regulator. It would not be a problem coz it osd consume much less power. I hope this will help you in readings on osd👍👍👍
That is bulls*hit. The voltage reading is a value that comes from Pixhawk. Pixhawk knows the voltage because the power module tells Pixhawk that. The voltage goes low because it actually goes low. This is caused by too low C-rating on the battery or otherwise busted battery. Change battery to something with higher C-rating.
depends on the type of person u are... its a hobby... theres greater satisfaction knowing how something was put together. when this one goes wrong u fix it. u cant do that with out of the box.
Andy's 100% right, some of us sit down for hours with our quads, it's our hobby. There is a reason many of us get a pixhawk or some of the more complicated FC's too, rather than just something we drop in with a very small feature-set.
+AndyRC If it ever see's the light of day as it's now nearly two years past its original release date. The only other comprehensive RTF OSD I've encountered is the EzOSD fitted to my IRC Vortex. Even the DJI OSD's require some form of surgical intervention 😜 Regards Nidge
Fantastic video man. You put a lot of description and explanation in your videos. Looking forward toward more!
+Wisterson thanks for watching i appreciate the feedback cheers.

thanks for the info. I'll have to pin all my hopes on the 3dr power module working then. cheers

+sputniksam yes everything was calibrated correctly in the battery monitor
All I want is the horizon bar, and lipo voltage. Would this be good for that? Do i need gps to get speed and altitude? Thanks :)
Hi Andy, I appreciate this video was done awhile ago, but from memory and in general can you have only signal wire going into minim osd from camera and only signal wire going out to vtx without earth?

Thanks for your efforts in general, my first ever question 😊
Is minim OSD support 4s lipo? I mean i am going to upgrade my drone with 4s lipo, so i want to know that can i connect the minim osd to 14.8 v supply?
I have two of them and i also hve the new micro version i never tested though but i am pretty sure it will work great as the big sisters do lol
That was a very detailed video my friend! Very impressive work :)
Thanks for sharing and have a great new week
+ABMNS PRODUCTION thanks. I hear the micro ones are more of a pain to plug to the mav ports i could be wrong though. I am all for smaller and lighter!
AndyRC It might possible, it's really small lol I will figure out when i will finally decide myself to use it probably on a new mini quad :)
Enjoy your week
great ill look out for it :)
Hope someone can answer, after jumping 5v to analog side should there be 5 volts at the 6 pin end?

Do you have a link to the black dampening balls used on the pixhawk?? I've looked everywhere for them and only found the blue ones.. Thanks!!

Hi Andy
Thanks for all these answers you have really helped me threw my quad
I am ordering 1000kv motors will these lift a gimbal seing as you used 920kv
Is there a big difference thanks
the lower the kV the more it can lift. 1000 should be ok
+AndyRC r u sure 1000kv will lift. The cheap gimbal you reviewed the heavier one will it lift this
+ReallyHarrison with small props and a 4s yes it will
+AndyRC I'm using 10 inch props and a 3s battery should I buy a 4s or will the 3s work
to lift a gimbal i would use 4s and smaller props
does it work with betaflight?

One more question if you are in the mood for it :) - Is the laserBGC android rx1 that you reviewed earlier this year compatible with this setup?
+Sarath Menon I'm not aware of that version of the osd. like I say there's a few versions. u will have to see what it's like when it turns up. yes the RX1 will work :-)

How about making an updated video with the newer micro minimosd, as the version you used in this video is not available anymore?
how about using the search button? ;)
Thank you ,,,

This is caused by too low C-rating on the battery or otherwise busted battery. Change battery to something with higher C-rating.
then please explain why an external voltage checker doesn't do it..
Nice video! Whats better, An Hermit 145 or an Ladybird FPV With picnic quadframe.
it depends what using it for. ladybird for inside. hermit for outside
But for racing and acro mode?
+Leon Beekveldt definately the hermit
Is it a good quality?
(The hermit 145)
Sorry but the screen showing Pixhawk MP parameters is way too fuzzy to read. Could you provide those settings in a readable format ? Thanks.
full screen hd is your friend :)
that "bug" is your landing aid 😁
+Bernie o'connor yes I have since worked that out thank you!
you will only get issues with ftdi clones if you decide to flash them,
then they'll get bricked
If 1000 won't lift it will there be any point in trying I really want a camera drone and will be using a gimbal
the multistar 2213 lift a gimbal on 8 inch props and those are 1300kv
+AndyRC I'm just going to use rhd 800kv with 4s and 10 inch props that should do the job
in this video im using 2216 800kv with 10 inch and lifts nicely :)
line you showing at 17:08 is for altitude, watch landing at the end of the video you will see :)
+Tomislav Teskač ah bloomin fantastic thank you!
I followed this using the same software but mine is in Chinese? how do I change that?
you have to upload the correct font package
+AndyRC do you have a link?
this is way too far to go to get an osd working. pick another brand that works out of the box, plug and play.
depends on the type of person u are... its a hobby... theres greater satisfaction knowing how something was put together. when this one goes wrong u fix it. u cant do that with out of the box.
Andy's 100% right, some of us sit down for hours with our quads, it's our hobby. There is a reason many of us get a pixhawk or some of the more complicated FC's too, rather than just something we drop in with a very small feature-set.
If you are selling this I will pay $1200 or more!
+Quadcopter World no not selling this is my only one
LOLZx
what a nightmare that is!!! much easier to buy rtf version!!
is there an rtf that comes with osd on its fpv? I guess the new hubsan x4 pro will
+AndyRC
If it ever see's the light of day as it's now nearly two years past its original release date. The only other comprehensive RTF OSD I've encountered is the EzOSD fitted to my IRC Vortex. Even the DJI OSD's require some form of surgical intervention 😜

Nidge
+sputniksam I'll be doing some vids on the slated hubsans soon. keep a look out :-)
On new Tarot XYZ-M everything works great out of the box as it is easy a 1-2-3!!!:)
