How to Build a Radio Telescope (See Satellites 35,000km Away!)

- Over the last 2 months me and my friend Artem (you met him in the last video) built our first radio telescope. It was built mostly out of off the shelf components, like a satellite dish and Ku band LNB, as well as some parts we 3d printed. When all was said and done we had a system that could not only take images of the sky in radip frequencies (in this case 10-12ghz), but could also be used to track satellites. With it, we were able to see the ring of satellites in geosynchronous orbit, over 35,000km away, This is only the first of what I suspect will be many more telescopes like this. Next time we'll be building ones that are far larger and can see things like the hydrogen lines so we can image the milky way.

Wow this was 6 years ago!!! 3D printing has come so far since then and I wish I could afford a printer to enjoy it and build things like this!!
It really is crazy how 3D printers went from a hobbyist pile of scraps to a well designed household appliance in a span of a couple years
A better way to rotate the dish is by using....
@@WilliamPoloValerio that's excellent, I think I'll do that.
I make my living as an Electrical Engineer, specializing in microwave radio systems, and I'm an amateur astronomer.
I mention all of this because it's the only way I know to describe how crazy hungry I am for videos like this one, and
how I gulp it down when I find one. This video is an absolute delight ! My hat is enthusiastically off to you guys.
Now, please permit me some criticism that I hope you'll find constructive:
Please give some more consideration to the question of what your finished video is to be. Is it to be a demonstration
of what you did, how you did it, how much fun you had doing it, how gratifying your results were, and how the viewer
can use some of your great innovative ideas ? Or is it to be an operetta, with some catchy tunes in the foreground
and some occasionally intelligible murmuring in the background ?
Why do radio commercials or TH-cam technical videos need music at all ?
And if music will be used to set a mood, then please don't use 6 to 10dB more music than it takes to set the mood.
The verbal description is the priority here. Until you can either dramatize the script with sufficient skill to make all the
details stand out from the background, or else hire a professional voice to do it, please highlight the priority content,
and put the background back in the background. Back off on the music. We want to hear everything you have to say.
I'm glad you liked the video :) As to the sound/music, the issue is that I mix the videos on a professional set of headphones and so it's really inconsistent how other people hear it. I can hear everything perfectly fine on my end, but on some sets of speakers it's much harder to hear. Because of that I've adjusted how I put the videos together and you'll notice that in new videos there's either no music, or it's much quieter.
The Thought Emporium Good ! Thanks for the reply. Reading more comments, I see that I wasn't the only one, so I know you've gotten the message.
This is the first of your videos that I've seen. But it's been like stumbling over a perfect diamond the size of a coconut, and I'll be searching for more to devour.
haha well I'm glad you like the channel! It's been a great year for content and I'm looking to make the next years worth of stuff even better
Al Cohen : They did not realize how loud the music would become after it was encoded. TH-cam videos are notoriously prone to that problem.
I built three Dicke radiometers. The work at 3.7, 11.7 and 20.8 Ghz with less than 1 K noise using a 0.1 second integration. The radiometers are much more stable than the total power radiometers commonly used. I describe the construction, calibration and measurements in an 80 page report.
Love the straw analogy. Makes the whole concept a lot easier to understand. Thank you!
"we may not fight wars of comets anymore." just wait till asteroid mining starts becoming a thing...
Eh. If it becomes a thing, we'd have so fucking much that it doesn't even matter anymore.
@@nizarch22 an asteroid or a comet is far too small to stop wars.
@@nizarch22 I agree, it would fuck up the economy so hard.
Wait till Marco Inaros hears of this
@@fureversalty XDDDDDDDD
Antena da Sky foi loco ahauahuahua - Excelente trabalho gente, parabens!
Será que ele é brasileiro? A marca da antena, as árvores, a estrada e as casas parecem iguais ao do Brasil.
Moises Castro O satélite que eles pegaram era um Intelsat, que a gente usa aqui no Brasil. Eu meio que já imaginei que era no Brasil, a vizinhança é bem típica.
Gente, é no Brazil sim... Florianópolis... Tem no vídeo anterior deles...
Que bom ver brazukas aqui nesse canal..
só me toquei quando vi o telefone, ahahaha poderiam colocar legendas em PT-BR...
I clicked cause I love radio astronomy, but you got a instant subscription out of me because of the music. It’s pure 70’s technical video background music and it’s wonderful
I hope you got a "A" on your project and were able to present at a prospective University Department you want to attend :). May I ask what are the best frequency range to observe supernova remnants, SNRs. I would be proud of your creation, share it with an Engineering Department-you will get a scholarship!
At 4:44, the 3d printer seems to play a remake of the Star Wars soundtrack "The Imperial March"(Darth Vader's Theme).
Really nice project, thumbs up!
In fact, that was the joke. It was playing it
r/wooosh
Seems? no it does mate :D, love it!
Darth Vader
Well, after years looking up on TH-cam for some crazy and nice DIY projects, after years of scrolling down "Hey guys today we are going to make X at home, to start you need these $50000 equipment." videos, finally I got a channel. First sub.
That's a very cool project, thumbs up!
thanks :)
You make some awesome videos too Crazy Danish Hacker.
Thanks :-)
Great content, but the background music drowns you out.
true
Simply great !!
I am currently setting up a home-brew 3.8 m radio telescope for pulsar monitoring !
Let's share experience !
That sounds like quite the build! I've wanted to do the same for a while now but haven't had the land to build it on
The science totally makes this video worthy of a like. The broken chair @ 10:55 persuaded me to give this video a second like so, I'll watch it under a second account for that.
i did not see building a radio telescope, this was building a mount for a radio telescope. a lot of info was lacking. how do you connect it to your computer , the software to use, decoding the frequencies from the dish etc. the video did not reflect the title. it looked cool when i first watched it and wanted to build my own. but now i watch it again , it just shows a complete radio telescope being mounted only.
Wow! Fantastic project! You combined a lot of simple ideas to create something spectacular.
The introduction to radio astronomy was great too.
David Bristoll thanks :) glad u liked it
Yes, despite your explanation, the music can be quite distracting!!! Especially while you are explaining how things work!
Totally agree, but at least it's changed now on future vids
U got be kidding me 🤣🤣
Love the inclusion of The Imperial March performed by the 3d printer that looked like it had been dropped down a flight of stairs.
Its super cool to see the progression of these dudes! From hot glue and janky 3d printers to brain stuff and genetics.
great video but can you please stop the music during explanations
I agree. Why is the music playing when the presenter is speaking? It adds noise and spoils this otherwise great video. We had to stop watching it.
Or at least lower their volume
Yes plaease
I am sorry but I have to agree as well. Whilst you are in the process of explaining things please don't play any music. Other than that what a really great video Thank You.
I actually liked the music. But maybe that's because I listen to these as I sleep
Idea: mount the dish on a tall 180degrees turning fan and make the support stronger with wood, reinforce the bottom plate with more wood and hot glue
Now team up with people in the Philippines to do some interferometry!
Lower the background music several db! As an amateur astronomer and an engineer now testing Electronic Warfare Systems both receivers and jammers, I like projects like this. I had Kraus's book "the big ear", and his book on radio astronomy.
All you need is the calculations taking your lat & lon, and cancelling out the earth's rotation!
Very nice!
That radio telescope was insane!! Great job!
I'm glad I found this video. I found this old piece of radio equipment and took some pics of it. This is helping explain it.
You guys are great. True American spirit of adventure and exploration lives here !
I'm canadian, but thanks
What a fantastic project! The concrete deserves an array of dishes working together.
The music was just fine for me, I could hear you clearly throughout.
May you have a lot of success for all this hardwork
Great job! I'm building something similar originally for solar tracking the sun.
I made some 3D printed worm drives that have a very high torque and need no holding current for the steppers.
As a result, they have microradian accuracy which is way overkill for solar tracking, but it can also do astrophotography, satellite tracking and radio astronomy just by changing what is mounted on it.
You don't need a bigger dish, you need more dishes. You can increase the angular resolution of radio telescopes by pointing two or more at the same object and measuring the distance between them. The images can then be combined like stacking exposures with optical telescopes. The larger the distance between the dishes and the higher accuracy in the measurements improve the angular resolution.
This is how we took the picture of a black hole. By combining radio telescopes from all around the world with accurate positioning we were able to have the angular resolution of a dish the size of the earth
The ionosphere of Jupiter can give you some interesting results. I believe you can use an old television yagi antenna to monitor the noise storms from there when the Sun is being active. EME stuff is super cool too. There are digital transmission protocols that HAM operators use that have excellent copy right at the noise floor. The software used for those is freeware, and you could use a computer soundcard to interface with a radio to transmit and receive, or maybe more accurately to encode and decode... your radio and antenna would be doing the transmitting and receiving.
Wonderful project! Keep up the great work, guys!
OMG!! I can not believe it. this is the first vid I saw on this channel and I'm loving it.
Absolutely marvellous stuff
Porra!! Brazuca na veia! Fiquei feliz em descobrir que vcs estão aqui na grande fazenda produzindo tecnologia. A tomada denunciou...
This is by far one of the coolest channels ive ever found
Love your channel, please please ease off on the background music. It's hard to hear you over it, and I want to listen to you.
Cool! Make it bigger and better!
Congrats on the construction and the results. I liked the video. Good work, I appreciate it. Have fun with future projects. :)
I like this AV very much.
BRO, YOU ARE ONE OF THE COOLEST GUYS I HAVE EVER SEEN ONLINE AND I HAVE BEEN ONLINE SINCE 1991 --- I WISH YOU THE BEST. PLEASE TELL ME WHAT YOU'RE WORKING ON TODAY. MAY YOU BE BLESSED WITH HEALTH ALWAYS!!!
The audio sounds good here... and I've got a crappy set of speakers. Nice project as well!
I'm currently learning about radio telescopes. That's great I found this video
SOLIDOODLE! I have one of those! EPIC piece of early comsumer 3d printing history.
That looks real high tech. Thanks.
Lovely project. Nice Star Wars plug with the “creative” musical instrument
Can't wait for the real radioastronomy
By the way, as someone who does occasional carpentry, this is some Frankenstein-level shit with that wood frame, but it's brilliant for sure. Love the videos, keep it up!
This was great and something Ive had a hard time finding or that was to the point. I like the section where the satellites are shown in the day. Thanks.
Video is pretty good and informative, good job on that, and gave the thumb up. Yes, I've read your comments about the background music, and I got it, still it was pretty destructive at certain points of your video. I would just drop it completely if hard to justify the proper level, your explanation is way more important than the music. Thanks and keep up the good work! 👍
This is why I sub to this channel. A labour of love indeed, for science and that, is so cool.
4:31 That printer sounds kinda like the floppotron but without the hard drive clicking...
Nice radio telescope
Love the music.
Love the musical instrument(3d printer music) at 4:39 :) Thumbs Up :)
You guys are always doing the coolest stuff.
"The only 3D printer we had access to looked like it had fallen down the stairs" *proceeds to show the same model of 3D printer I own*. Poor little solidoodle.
Mad respect, you guys are true scientists
Yay, now something to use some of my satellite dishes for!
Very nicely spoken. Was a lot of work. You must really Enjoy what you were doing.
Very Cool Project ! Well done guys ......
Amazing video, but yeah, your background music should be quieter, it's background music for a reason, not the main point of the video xD.
Keep it up.
This was very informative.
Car power window motors are readily available and usually have a decent gear system already built in.
The auto generated closed captions for this are hysterical! Great video though!
Awesome work! 👌
Very cool. As a science teacher I would love to see a simpler radio telescope I could build and use in class. Please publish your plans!
The simplest radio telescope is just the dish and the satellite finder. As you move it around, the sat finder will only make noise if you're pointed at the sun or one of the satellites. It's a really simple demonstration I think your students will like :) All the motorized bits were just because we wanted to make an image. I'll upload all the 3d models on thing verse or something.
Pls add a written tutorial to thingverse too for follow-up steps or replicate your beautiful project. Nice work
Did you guys ever got a chance to upload the models?
Hello! I’m curious how you got an image from the dish, as I am still confused about it. Another question I have is how you would look at something like a planet, something that looks only like a dot in the sky. Is there a way to zoom in on an image? Any help is appreciated, thankyou!
Ill assume in your question, you're not much familiar with physics and techs but I would suggest learning it since you have access to internet. There are tons of it. You would quickly learn a lot, I know you are curious. Hope you succeed in your project.
the image is just a heat map of how strong the radio signals are
@@omniyambot9876 can you suggest anything to learn about tech,,,also I didn't understood ho can we convert radio signal into image so can you please explain me that?
The first few minutes of this video are dedicated to explain exactly that 1:50
Amazing! Thanks for sharing!
Nice job
OMG, it's like the McGuyver Brothers! Great job for such an ambitious project t! Awesome!
I love your channel, your work inspires me to do more complicated projects, and has fed my drive to fill my lab full of cool tools lol
this is so awesome dudes, cant wait for more like it!
This is so well made it should be on the science cannel
Thanks :D
Oh, I hit the like button immediately after that imperial march!
I wish I had science buddies but everyone in my country barely know how to eat,have babies,and some of them know how to work and get money.
And the worst part is people with intelligence leave the country for money (they are not poor they just want to be rich) and the brain dead and scammer ones STAYS FANTASTIC.... I'm only 16 and I'm saying that.
Thank you for that!! It was deadly👍👍
I am glad i stumbled upon your channel!. Your content is soo amazing and unique!
😎 Awesome! Learned so much here! Thank you!
please remove music or lower the volume of it from the video. Good video tutorial
Hello, try a noise cancelling antenna! Here's how it works, it uses two antenna. One sits in the focal shadow of the receiving cone. One antenna faces the dish, and accepts focused RF. The second antenna catches all that local radio noise astronomers hate, a straight antenna behind the focal plane a ground plane separates focused from noise by geometry, on the parabolic side is the focused from space receiving antenna. Now, we just use plain old phase, keep track, and build a operational amplifier to eliminate unfocused noise by means of common mode rejection. It is the same as noise cancelling head phones but, all RF. Have fun! The next phase, dual equalizer input op amp variable gain stages. You can amplify until you hear the atoms the transistors, we the use a variable notch filter to cancel it out before it's distorted by cut off or saturation, and continue until the motion of one electron, equals 1 watt, or 6 to the 28th power of ten .
How to get rid of noise. Next, power levels, long exposures, and the search for common denominators due to photon scattering destroying signal data over great distances to find units of measure, and hidden base n features. Like finding signals in powers of ten, or six because, they only have a total of six fingers....
Switch to an telescope's calibrated movement, or calibrate yours so that if you find something, you can tell other astronomers where to look.
The only lenses you get are amplifiers...
You'll be fighting 60 Hertz all the way. I did build amplifier with that kind of gain, and every stage or two, I had to us a notch filter to put the 60 Hertz on both inputs and the whole signal, on only one input. Recursively using common mode rejection.
Get me a lab set up, and can burn water, and do more!
Amazing!
Ammazing work guys nice work 👍👍
This was totally awesome, Subbed!
This was really awesome......
This is awesome! 🚀
Simply beautiful .... I, myself, am planning to build a radio telescope! But I don't have a 3D printer. Thus, the gear part will be a struggle for me. I am trying to achieve the electronic part of the Radio telescope; filtering,imaging and stuffs, using Arduino. I would love to share my ideas with you people.
for the gears you can always use a 3d printing service, or find a local maker space if there is one. It'd be fairly inexpensive to get those few pieces printed out. If you do end up building one, there'll be a chance to collaborate in the near future
Indeed this is what I believe in, Collaboration replacing Competition!
awesome! you guys did some amazing work!
The music spoiled this upload.
Great project! I really like your videos!
This is incredibly interesting
At someone found a good use for a Sky TV dish!
friggen cool guys!!!
thanks :D
Awesome!
the weakness parts of your systeme are the gears they are not enought stronger , with time you will have gears issue all the time and with the wind it will be more worst ! but your idea is not bad at all ! ty for this video !
nice job man 👌this channel is gonna blow up one day and i cant wait
Thanks :) I really hope so :)
What a freaking awesome video……. Wowwwwww 🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰 congrats on your future projects 👏👏👏👏👏👏👏👏
Brilliant 💗
Hey thanks for this it was really cool to see.
This sounds like a great way for a two dimensional solar panel tracker, even with overcast. It would be immune from bird poop and leaves. It could be directly integrated into a plc or basic stamp controller and it is direct measurement, not inferred.
