## Introduction: IOT Based Radio Telescope

Hello ,

This project which i am writing is based on our IOT based radio telescope. In this project we are planning to fuse radio astronomy and the latest technology of IOt which is (Internet of Things). So in this project our aim is to create a radio astronomy environment and then control it with or using a smart phone which will be accessible to the internet. So now let me tell you what Radio Astronomy is. Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object.Radio astronomy is conducted using large radio antennas referred to as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis. The use of interferometry allows radio astronomy to achieve high angular resolution, as the resolving power of an interferometer is set by the distance between its components, rather than the size of its components. So in our project we are plannning The

### Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: Power Supply

This is how your telescope will look like. And the next step also will be fun. You can use either battery or adapter no need of the above circuitry. Use what ever you are comfortable with. Its a nice and fun job to use wires and battery. Here are some links which you can use to build your own radio telescope.

Battery:

You can use any of the above of 12 volts.

## Step 2: Arduino Code

Here is arduino code which you can use. To move the 4 moters please repeat these steps to the number of moters.

CODE:

int motorPin = 3; void setup() { pinMode(motorPin, OUTPUT); Serial.begin(9600); while (! Serial); Serial.println("Speed 0 to 255");} void loop() { if (Serial.available()) { int speed = Serial.parseInt(); if (speed >= 0 && speed <= 255) { analogWrite(motorPin, speed); } }}

After loading the code connect your moters and see if it works. And after connecting all to a bread board and all the wires enjoy the moters ride.Now the next step.....

## Step 3: IOT Again the Modern Craze.................

IOT

The internet of things (IoT) is the network of physical devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data. With this after finishing your moter work now connect your arduino to the IOT system. using the usb port connect a internet dongle and the code your IOt module. I cant provide the code as it differs so start coding.

## Step 4: What Do You Use.

You can use ANYTHING JUST COME UP WITH YOUR OWN IDEA AND PING ME. It just the depends on your imagination use what ever you want to use.

## Step 5: The Reading You Get:

Use whatever software you want to get the readings and here are the images which you will get. And then explore Quasars , galaxies and Pulsars whatever you want. I will soon write how to use interferometry and get your reading in the next instructable.

AND THEN YOU VAN SHOW OFF AS YOU WILL THE FIRST ONE TO MAKE IT IN THE WORLD AS IT HAS NEVER BEEN DONE BEFORE.

THANK YOU AND PLEASE VOTE FOR ME. You can ask me any query and i shall try to answer it.

Can I know what software you are using to get those images?

Bonjour tout le monde. Je crois que tous deviné!!!!! Ce projet est une illusion et infaisable dans son ensemble car, les images ont été volées un peu partout sur le net et c'est dégradant pour ceux et celles qui font un réel travail. Cela a ni queue ni tête. Impossible d'avoir de telles images sans traitement par un tiers programme. Foutaise totale. C'est sorti tout droit de l'imagination d'un enfant. Ne perdez pas votre temps ici. Profitez plutôt des réels beaux projets INSTRUCTABLES.

Looking forward to seeing this when it's finished.

I don't mean to be a downer but I'm highly skeptical you can produce images like the ones in your last step using a satellite TV antenna. For starters, the dish is only tuned to TV band frequencies, so at the very most all you will see are pulses where the geostationary TV satellites are. Even if you built a LNB (thats the thing that sits on the pole out the front to collect the signals) that is tuned to other frequencies, the small size of the dish means you could not collect enough radio waves in the same way you can't collect enough light to completely resolve Saturn's rings on most cheap telescopes. There is a reason real radio telescopes are so gigantic and assembled in large arrays in the middle of the desert - to collect as much energy as possible.

Sat dishes are also like lenses - they funnel electromagnetic energy from a relatively small field of view which means they are highly directional. The best you could do is either painstakingly move the dish by hand and record measurements at increments and assemble them into an image.

You should cover the mechanism you used to rotate the dish. Servos have a limited rotational range and torque meaning they are better for small things - you'd probably want to go for a stepper motor to change your azimuth, and some type of linear actuator to change the altitude. Both can be controlled very finely with a microcontroller.

yaar im so excited to do this... get me the remaining steps fast ;)

Wonderful idea Kabir.

We're all eagerly waiting for the rest of the steps.
