Hi, I'm Adrian from Hungary.

Let me introduce my vision which became reality!

My idea was to make a portable ground station that includes all necessary components for FPV flying or piloting an Arducopter. I decided to use these parts from my previous ground station:

  • Futaba FF9 transmitter with FASST module
  • 868 MHz 3DR telemetry module + USB FTDI panel
  • 8" LCD screen + control panel
  • time base corrector (for screen to avoid sleep)
  • Iftron nano 5.8 GHz video receiver

I decided to add extra functionality to my ground station. Instead of using my Mobile phone, I bought an Android MiniPC (MK808b sunvel clone) and connected to the LCD via HDMI. My first idea was to use a touchpad for input, but I couldn't find any that could match my requirements. So finally I bought an USB ring mouse! The mission control app is Droidplanner.

After I had all the required parts in front of me, I started to design the shape with a 3D engineering software. Here is the final result (rendered 3D images):




Basically it has a top and bottom layer made of 2 mm black glass-fiber plate and FDM-printed spacers/side plates. 

The ground station has the following sockets/peripheries:

  • 2x USB and 1X USB OTG port
  • balancer port for battery
  • video and audio RCA output
  • trainer port for simulator
  • 12V DC input for using external power supply
  • 3 antennas: 2,4 GHz transmitter, 5.8 GHz video receiver, 868 MHz telemetry
  • port for teach panel of time base corrector

I'm using 9 cells of 18650 size Li-ion (3,7V) in 3P3S configuration. With 1.3A measured consumption ground station can operate more than 4 hours!

After I received all parts, I started to put it together. It took 2 weeks, with endless amount of soldering...and also had to make some PCBs for trim buttons, LCD control, power distribution, etc.

Here is the final result:

Here are the external connections: 






The ring mouse and the power switches:



UPDATE: Under the hood...


Finally I'd say thanks to the following team/people:

  • Ground Zero (www.groundzero.hu) for help in 3D printing
  • Arthur Benemann for Droidplanner
  • my friend for sharing his CNC mill station

For further information, please connect me by mail: nhadrian@gmail.com

I'm not planning to produce since it would need serious investment. For example, the FF9 and the 8" LCD screen that I'm using are discontinued, so replacement should be bought...


Best regards

    Any photos of inside or top opened ? , would love to see the placement/wireing harness theme.   Two things I would change is 

    bigger Leds ( right now they are smaller than the markings/details.  Power switch  moved to top or separate location near top with flip open cover ( don't want to switch off in heat of action ).  Cheers

  • I tried many variations of firmware for MK808b. Unfortunatelly, not every firmwate support FTDI. So maybe you shoult look around for custom firmwares for mk802.

    About screen, this would do the job: http://www.ebay.com/itm/7inch-HDMI-monitor-kit-HSD070PWW1-C00-690cd...

    It has good resolution and 690 cd/m2 is more than enough. 

  • I have a Smart TV MK802 but I can not connect to xbee could help me I'm trying to do the same but with a futaba 9cap, will have a diagram mk802 connexion with thanks. I congratulate excellent work

  • Wow, what a great piece of work ! Hats off to you.

  • Developer


    When I have some time I'll write a more comprehensive comment.

  • I'm impressed, a true work of art!

  • Amazing work. Will you post the cad files so we can modify to fit other hardware that are available? I can certinatley help with modeling if someone else can do the hardware configuration :)

  • One thing about the RC Tx implementation is that most of the menus and features in a hobby Tx (Futaba, Turnigy, or other) is that they are an unnecessary complication.  The majority of the actual flight control actually takes place on the flight controller.  So, beyond a few basic things like Expo, or maybe dual rates, we don't need many features in the Tx. We don't even need servo reversing.  It just confuses new users.  And for advanced users, they still don't offer the one thing we really need:  Pushbuttons for mode selection.

    One problem with many of the Android tablet screens available (the first one Alejandro linked is really interesting looking) is that they do not give good sunlight readability.  I think any screen that is "cheap" will be pretty bad.  I recently won a <$100 Android tablet in a raffle and, it's just awful.

  • Would be awesome to have community around this. I mean if we have plans available of carbon fiber and 3D printed pieces for common radios FrSky/Turnigy/Futaba etc and ARM dev boards It would be easy to DIY AIO GC.
