Building a on the go system


#1

so iv been building a on the go system for using using a expandable dish im building it for multiple uses such as Outernet Connection, VHF/UHF, Sat connections and of course TV … the dish is 40cm when it is opened flat and I have revived Outernet Signal from that using a normal LNB just fine.

iv built a nice housing for Raspberry Pi and Receiver so its now a all in one and can run off internal battery and recharged with solar panel on top similar to the lighthouse in a way…

what im looking for now is a LNB, not just a bog standered one, a small one so it can be trasported in a small system like the dish and fast deployed… i know they exist iv seen small ones not bigger then a old nokia phone that was picking up Sat TV from around the world… but i cant find one recently… anyone got an idea of one that i can search for…

also have the dish made out of old sat dishes cut and welded with hinges… been looking at the idea of getting a pop up aluminum camera light, have read on reddit they can work aswell…

The Idea behind this is, i can go to an event such as Concert or something, pull this system out of a Backpack and set it up somewhere so everyone can connect to it in the area.

I would be very interested in seeing some photos of your setup. Sounds very exciting.


#4

yeah sure im in the UK at the moment on work, will be back at the workshop monday, will post then

can say i got my idea for the dish from here http://1.bp.blogspot.com/-WpuTN8PX6TM/Vgp2KX83_6I/AAAAAAAABrs/_uFRaZiAxoY/s1600/UT8MqGCXmJcXXagOFbXj.jpg

actually just thinking at this, if i was to buy a few of these and weld expanding plates end to end it should be able to expand into a larger solid dish… from what would look like a tube to a large dish

Have you seen this?

We originally tried to get in touch with these guys but language barrier and stuff… didn’t work out.


#8

didnt see that before

dont see how that would be a hard system to build … looks like aluminum mesh warped around bent struts, attached to a base with small motors… the only thing id be confused about is the antenna they have in the center … from rough translation he says its for mobile phones in a disaster… so im guessing the antenna is for that, but i dont see how if a small LMB was found it could be adapted instead of the antenna…

go next level with it, a ardiuno program could be wrote with motors to make the Dish automatically Align using a GPS head… that would make the kit bigger but could be designed as a plugin system, so each peace fits together.

this suport Ku bands ?


#10

thats pretty cool… but costs abit and is big… im trying to build something on the cheap and be about the size of a pringals tube when packed…

just taught of a cheaper way using a cheap pound land umbrella and aluminum mesh for screen doors as a pop up dish

is that from a magazine … cause thats a magazine id like to read :slight_smile: … its always hard to find a good magazine with stuff like that


#13

This is sorta the idea I had = http://www.g6lvb.com/images/dish1.jpg

this maybe cheaper = http://www.qsl.net/kd6pag/gfx/TwoDish1.jpg

So i was in Ikea yesterday and came across a veg steamer … got me thinking… This set up in the picture just pulled in outernet and started downloading data … signal wasnt grate but still got it…

Veg Steamer €2 in ikea Bargin Bin
bendable Phone Holder €2 Local Chinese Phone shop
KU band LNB €3 For China on ebay
universal camera Tripod €2 local bargin shop
1 meter coax cable with connectors €1

I dont think i can make an dish to get the outernet any cheaper …

Also Must add… HDstar and Raspberry pi cost near 100 so im not counting that im only taking dish


#15

Can you tell us the diameter of the veg steamer. Also post a screen capture of the settings page so we can get the idea about your new setup. :slight_smile:


#16

the diameter goes out to 38cm’s as far as i know its the large sized one there was 3 sizes in ikea … il do the settings tomorrow as im running out to college now … but I was connected to 13.0E Hot bird not grate cause i was using my phones GPS to line it up and it lined up passing trough trees so il try a better way or position tomorrow and get a screen cap…

everybody saying min is meant to be 60cms but im getting it on the 38cm dish… got it on the 40 perfect, thats in the hacker space so i need to go get that and do photos of that

I tried to connect a spare LNB to my existing dish more adjacent to the LNB holder. I got the signal but no signal lock. Later I realized that it only works when I attach the LNB to the holder. For other positions it doesn’t work.
