Well first of all I'll start with the reason I chose to build this ground station instead of using a laptop
So after many times of carrying the laptop around assembling and disassembling parts and cables xbees usb cables and such I figured my laptop days as ground station will be numbered
Because of this I decided that I needed a ground station that would save me the need to deal with the assembling and disassembling in the field and will be more durable then my laptop
First I had to plan my shopping and inventory list
I had an old laptop with a broken screen that did not survive its frequent trips around and my poor handling skills And an older laptop screen that i planned on using with the other laptop mother board in order to do it I had to buy a lcd adapter that will let me use the vga port on the motherboard with the lvds laptop screen
That's about what I had to start with
The second thing was to look for a case that will be large enough to contain the mother board the screen another small screen that will fit in the remaining space and some lcd meters for giving a better look mostly and some 3 position switches
After many searches I found an old stock of Pelican at an affordable price and size that is suitable for my budget and needs i measured the space that left after installing the main screen and figure out that a 5 inch screen will just fit
then i needed to think of a way to install everything in a way that would give me easy access to the parts just for any case
after trying multiple materials Plexiglas plywood and others which are not very easy to work with without machinery which i didnt have access to i found just what i needed a pvc foam it is not the perfect material consider his toughness which is lacking but it is very easy to work with and so i chose it and start to cut holes and install the switches and lcds
for the finishing touch of the station i used a vinyl sticker in a 3d carbon woven pattern which gave the panel a nicer look
some technical details:
for powering the station i chose to use a sla battery instead of lipo for some reasons
first it is easier to deal with in terms of charging it and is much safer then lipo
second it is cheaper and heavier so I can save money and use it for balancing the case
i also wanted to be able to hook the station to ac power when its available
so i searched for some ac/dc converter that will meet my power demends and it turned out that i missed it in my calculation by a bit but for the moment it is working and i see no reason to change it but when it brake i'll certenly buy a bigger one capable of outputing more current
I then wanted to charge the battery while using the ac/dc convertor and giving the station more reliability i found a charger which is also a ups that is just what i wished for
also used step up regulator from 12v to 19v for powering the motherboard
and a step down regulator from 12v to 5v for powering the usb hub
both regulators are adjustable with lcd meters for convenience reasons and capable of outputting more current than consumed
bom for the station is:
laptop mother board and screen - free
pelican 1520 - ebay
LCD Controller Board DIY Kit - for connecting lvds screen to the motherboard - ebay
VGA 2AV driver board 5inch HSD050IDW1 800×480 screen - ebay
12v to 19v step up convertor with lcd for powering the motherboard - ebay
temperature meter with two sensors (inside and out of the case) - ebay
power meter with 2X lcd voltmeter and amp meter - ebay
12v to 5v step down convertor with lcd for powering usb hub - ebay
picoUPS-120 12v dc micro ups system - ebay
4X 3 position 6 pins switches - bought at a local electricity store - ebay
4X Delta Fan for Compaq 12vdc .15A 40mm EFB0412HHA - ebay
3d carbon woven pvc vinyl sticker - deal extreme
ac/dc convertor 100-240v input 12v output 3.2A or higher :) - ebay
pvc foam sheet - ebay
access point modem asus wl-330ge - ebay
usb hub 7-ports - ebay *
thermal skin for wires - ebay
* if you want to build your own usb hub you can do it using fe1.1s chip or similar very easily
**and so on with the other regulators it is just to my believe cheaper and faster to order it assembled :)
features of the station:
up to 2.5 hours of use on a single 12v 7Ah sla battery
secondary screen switchable between av and vga (via pc hdmi port and vga converter)
wireless connection to antenna tracker (xbee repeater, Bluetooth, 5.8Ghz)
access point modem - for multiple connection to the station (andropilot for ex)
can be easily modified and upgraded
sorry for my poor writing and description capabilities/skills
the uav station is not done yet still need to do some more things I will update the post as It go
all you need to do is buy some tools read some technical stuff have a vision of what you want to build make a sketch and find out that almost nothing work on first trial as you aspect :) give you a chance to modify and improve it as it builds
I guess you can use this kind of station for what ever you want it's just a control station
regarding the small helis I would go maybe on a small tiny pelican with 7" touch screen (dumping the need in keyboard or mouse) maybe use a small ps joysticks as they are cool and durable
and filling the bottom of the peli with embedded pc / pc on board / pico\nano itx of some sort with lipo batteries
should cost around 300-400usd with tools and miss ordering

I have my GCS working on the bench now. I am using a mini-ITX with an Intel Atom motherboard and a 128GB SSD. I purchased a new 15" WXGA LCD display off of eBay and am using a VGA to LCD converter to connect the PC to the LCD display. Everything works as intended. MP looks nice on the WXGA LCD screen.
I am now in the process of mounting the LCD display in the top of the Pelican 1520 case. I am using rubber isolators to mount the LCD panel to help reduce the effects of mechanical shock to the display. Next I will mount the mini-ITX, which is in its own case with two cooling fans, in the bottom of the Pelican case along with the 12vdc SLA battery, car battery/internal battery switcher, and last but not least a mini keyboard and touch pad. I should have it done in about a week or so.

that's sounds awesome
upload some pictures of your work (documenting it will help you also in the future to remember what goes where :) )
have you considered adding a picoUPS just in case you want to use other power source along with charging the battery?
Ya Pics pls Tom. thanks
I would also like some detailed pictures of this, and if it's not much to ask for, please let us have a detailed list over your items used to build this GCS.
I'm in the process of building something similar, and would appreciate all the inputs/help I can get.
Yes, I will upload some pictures as soon as I have the LCD panel mounted in the lid of the Pelican case. I am in the process of mounting the rubber isolators to the inside of the lid of the case. The rubber isolators have 8-32 threaded shafts that are screwed into HDPE plastic squares that are epoxied to the case surface. The other end of the isolators have threaded holes that I use 8-32 SS screws to attach the panel to the isolators.
The LCD panel mount is made up of a 1/4" thick EPVC panel and a 1/8" thick Masonite panel with the LCD display sandwiched in between the two panels. This way the LCD panel floats between the two panels and is shock mounted from the case lid.
I then have a VGA cable and a power cable for the VGA to LVDS converter going to the bottom half of the case where the mini-ITX PC is located along with the 12vdc SLA battery, keyboard, touch pad, and car/internal battery switcher (Micro UPS).

You will need an ATA CDROM drive to install Windows on the SSD if you do not have one already.
I also purchased four Male A to Female A panel mount USB extender cables to make it easier to hook USB cable devices to the mini-ITX: http://www.adafruit.com/products/908
The reason I bought a number of the items from Amazon.com is that I am an Amazon Prime member which means no tax, free two day shipping, and a pretty liberal return policy, especially on the SSD, The Amazon.com Pelican case price is within just a couple of dollars of what they charge on eBay for the same case, but used. The issue, to me, with buying the used case off of eBay is the shipping charges which are usually around $20.

Congrats for making it to Hackaday!
thank you very much
been on a vacation in Catalonia for a while and between my job and school
I don't get much chance to work on the station and the drone but it most defiantly gave me a drive
to finish everything in the near future
and i hope that more and more people will join this great site and this wonderful hobby
Okay Gentlemen, here are some pictures of my GCS. It is almost done. I still have to paint the top plate that covers the SLA battery and the mini-ITX computer. I am holding off painting the top plate so I can add a couple of small speakers and a 1 watt amp so that I can hear the MP voice:-)
Here is a shot of the open case. On the right side is the small touch pad and on the left is the keyboard. They are attached to the top plate with Velcro so they can be removed easily. The row of A Female USB connectors allows me to attach the keyboard, touch pad, USB WiFi transceiver, and the 3DR 915MHz telemetry radio to the mini-ITX computer in the bottom of the case.
Here is a shot of the top cover minus the keyboard and the touch pad. The slot above the keyboard is where the mini-ITX fan exhausts are located. The vertical row of holes in the upper right are for a battery indicator so I know when to charge the onboard battery if I am not hooked up to the car battery or the garage battery adapter.
Here is a shot with the top plate removed. The SLA battery is in the lower right hand corner and the mini-ITX computer is in the upper left hand corner. The mini-ITX case houses an Intel Atom 1.8GHZ twin processor motherboard, a SanDisk 120GB solid state drive, and a very compact switching power supply that runs off of 12 - 25vdc.
In the upper right hand corner you can see the power connector for the car power input, an auxiliary 12vdc connector for a FPV radio receiver, and the mini ups (in a black protective case) that switches between the car power input and the onboard SLA battery.
Here is a shot of the 15" WXGA LCD display. On the back side of the LCD display is the VGA to LCD display converter. The tape is holding on a protective plastic screen until I finish the GCS. You can see the LCD display control push buttons in the top center of the frame. The LCD display is sandwiched between a piece of EPVC and the black top frame. The EPVC plate is attached to the case top with four rubber isolators and there are poly crush columns spaced around the bottom of the EPVC plate and the case lid.
This shot shows the GCS in action with the MP being displayed on the LCD screen. You can see the VGA cable and 12vdc power cable over in the lower right hand corner of the frame going into the top plate.

excellent work looks very professional and nit
great build !
how do you intend to recharges the battery? I see the plugs on the right and the box with the picopsu
do you also have an ac-dc adapter? or do you plane on charging it from a secondary battery?
