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
Very good job. Would love to make one like this soon.Will be in touch when I start.
One more thing.Instead of hardcase keyboard, you could use rollable rubber keyboard that can be placed inside.
Good Job Elad, but there is some potential issue needs to point out:
2.Rainproof, nothing really, just capable for expected mission!
rain isn't much of a problem here so each and is own custom specs but
I guess that if you really want to make it an all terrain-weather proof you can just coat all the surfaces with hydrophobic spray or paint mount the vents differently add a filter for dust and you got a all terrain/weather control station without much of an effort
or you could cut a piece of dark nylon and use thin carbon tubes for forming it the shape and size you need and make it foldable so it wont catch much space that way you could also improve the station screen readability
regards to the field assembly I plan to place it on the tripod so i just need to epoxy mount hole at the case cg
sorry for not taking care of the post lately
I hope that soon I can get back to the project and finally finish it
write a complete manual/guide for the control station and hopefully also for the plane that should go with it :)
best regards and great weekend
Awesome work you laid down in building this station. Somehow exactly what I'm looking for to build for myself. I would really like to see your complete manual/guide on your control station.
I have an old Acer Ferrari 4005 laptop that I'm planning to use for my station. All I need (for now) is a complete PC system, so I can use this "control station" to update/maintain my quadcopter (3DRobotics with APM 2.5) and to use the station to monitor my video transmitted from my quad with OSD.
Already got my hands on a used Pelicase (yellow) for this purpose.
WOW! In my dreams ;) - might have to ask my techy guy to help me out... Thanks for the post, awesome job!
Can you tell me the inside depth of the lid of your Pelican case? I have not been able to find information on the inside depth of the lid for the Pelican cases. The website only gives the internal depth from the top of the inside of the lid to the bottom of the compartment.
I am presently putting together a GCS to be powered off of my car's battery with a SLA battery for backup. I am using an Intel mini-ITX embedded Atom motherboard that runs off of 12 - 25 vdc with a 120Gb SSD. The mini-ITX is running MS W7.
I have looked at various 15" LCD OEM displays and the Pyle 15" LCD is self contained and is designed for RV installations. It only needs a VGA input and 12vdc and comes in a shallow metal chassis that I think will fit in the lid.

the lid depth is 1.79" (4.5 cm).
here is other specs
Thanks for the link. Much appreciated.
I am just about ready to start installing my GCS components in a Pelican case and have been evaluating the different size Pelican cases for suitability. I have found that you can buy brand new Pelican cases on Amazon for not much more than the used ones on eBay if you belong to Amazon Prime and get free shipping. The shipping on the used cases on eBay is usually $20 or more. If you add that to the price of the used case, then you are pretty close to the price of a new one on Amazon.

Some of the ebay prices for Pelican are very low compared to new ones. Amazon prices have been higher compared to ebay in some cases. In any case shipping cost is the deal killer. I am still searching for the case.
Looking good! Keep up the good work when you can.
