This is just awesome! I used to build FM radios back in the 70's with discreet components, in fact my first stereo system was entirely self-designed and built. But it's been years (make that decades) since I worked on any audio projects and I had assumed that these days with gear being so cheap that nobody was doing it anymore. You have restored my faith in the spirit of building home-made electronics. This is a beautiful design, and to anyone who asks "why not just buy a cheap one from China" all I can say is that they don't understand what it means to design and build something from scratch.
Not exactly from scratch. The amplifier was already there. The FM IC is already there. The digital potentiometer is also there. The LCD with built-in controller is already there. However I agree with the spirit of your comment. It's a great satisfaction to build something from bits and pieces.
Please don't be fooled by the text put on the encoder board. It's not Clock & Data - It's two phase signal, 90 degrees apart. It's called quadrature encoding.
That radio module supports volume control, you don't need digital resistor ic, you can control volume from arduino code. It supports RDS function too, so you can display radio info on screen, also you could save radio stations freq on arduino epprom memory, so you dont have to input frequency when powered on.
Awesome follow-up on the I2C video. As usual top notch edited video, and voice-over. (still it's a funny accent, but by now, it's a trademark!) Looking forward to part 2 and the schematics and sketch.
Nice project. I agree that the the prebuild class-D amp would have simplified the final circuit, but it looks like a good build nonetheless. Thanks for sharing.
GreatScott, I have been watching your channel for quite some time now, and love the way you go about making your tutorial/project videos. I was wondering if you would consider using an old CRT TV to make an oscilloscope. Not as a substitute for a modern one, but I think it would be enjoyable to see you make a video using old technology to make something cool. I personally have done this with little effort, but I figured you could go into more detail, and possibly add more functions than the one I built. I am an aspiring electrical engineer, and look up to you. So thanks for everything you do.
Nice video! I would have liked to see a little bit more info about the superheterodyne process and how it works/why it's used etc. IC's are very "black box" - where all the complicated circuitry is hidden out of sight, and unfortunately, out of mind. I think there is value in knowing the basics of how the mixer IC and amplifier ICs actually work beyond just how to use it with an Arduino. Perhaps in another video you could explain these processes. Keep up the good work!
Wow! As some1 who had gone through the full "grind" starting with intense valve, transistors and now Ic,s almost all of them in analogoue with intense practical experience in a wide range of consumer electronic equipment i can only sum up your efforts as simply awesome. Gr8 gd wrk man. Keep it up and don't listen to rookies asking for simple stuff. There's awful about of stuff for those guys on the net anyway.... Gutsy keep going...
.Scott , I am in college right now learning electrical engineering your are the most interesting channel I find in youtube , keep uploading videos that educate us. My project is to build an digital oscillator using PLL VCO keypad 8051 and altera card :D keep doing what are you doing Scott ! looking forward to Part 2 !
+SomiTomi There were digital radio interfaces 25 years ago but I understand what you mean by the golden era. Now-a-days, it's wifi/bluetooth/nfc/etc operated.
subsynchronous I know, I have an '80s Hitachi receiver (or as it refers to itself: "Microcomputer-controlled quartz digital synthetizer tuner", I'm not making this up) with a really nice looking VFD on it. I kind of like all sorts of radios actually, I just like ones with no IC-s a little more.
I think i remember a project that could potentially be repurposed. Jeri Ellsworth designed herself a thought sensing lightbulb hat that used a temple electrode and a very sensitive amplifier, i think she wore that at some convention or other. I recall seeing her project video, with explanations and schematics on her channel.
Dear GreatScott! I congratulate you for your project. MCP 4151-502EP M19 1528 with integrated package types When you measure the P0B and P0W pins shown in the diagram, I cannot get 5 v and the voltage shows zero. writes 1317 on the bottom on your MCP4151. I use different integration. Thanks
what are the odds of me just learning about a superheterodyne receiver in my electronics communication class only to see one of your newest videos using one of them.
Terrific video! This video compares favorably to the quality videos of Make Magazine. I would really like to try this project. By the way, there will be many other comments that say, "Why don't you just buy a radio?" They'll never understand. Once again, excellent project.
man i need to find that teaches you how to use a breadboard and schematics at the same time. i will for sure build this one day!!! thanks for the vid. i am still learning. got lots of parts and an arduino, time to get busy hahah
I really like your perfboard work as it's very tidy. You should consider investing in a bag of real connectors, though - those headers with the wires soldered to them look all but nice. I personally like the stuff you find when you search for "PSK" and "PSS" at Reichelt very much, but simple Dupont connectors would probably do as well.
it are needing more one amplification stage and one auto-gain circuit interconnecting (monitoring the 2nd amp. stage and inserting on the first stage) the two amplifier steps
Is there a place I could get the schematic for this radio and wanted to know if you have any plans in the near future do anything with a ham radio.. Would love to see a step by step guide of how to build a 2meter SSB radio.. I could probably find something on the Internet.. But love the way you put your videos together. Thanks again and keep up the great work
I like you use rotary encoder. Never see something practical way before! //Maybe use ATTiny to calculate length of encoder and send data via i2c to make turning smooter. ;)
+TeaDrinkingIlluminati 3W is already quite a bit. If you want to learn more about class D amps then you should check out Afrotechmods channel. He made a great video about those.
+TeaDrinkingIlluminati 3W is enough, just all the big companies adverties with like 1000W because people who know nothing about electronics just thinks its way beter then 500W
+TeaDrinkingIlluminati You don't know what is powerful until you used D amplifiers. There's a 2x50w one sitting next to me and it is a beast. If I pull the volume up with no output on, I can hear the inductors squeak to the rhythm :D
Wouldnt that small voltage regulator module eventually get to much power pulled threw it? Then again since you are using a single cell lithium battery it seems the circuit isnt drawing to much power. I used one of those small modules before and it caught on fire. Looking back, maybe i shouldnt have had it assist in powering a 100w led....
Sehr schönes Video! Für mich ist das Projekt aber leider schon wieder "zu hoch", was auch an meine, Englischkenntnissen liegen mag :D Jedenfalls schau ich deine und ähnliche Videos sehr gerne. Als du den Akku verbaut hast, hat mich das an diese mobilen Boxen fürs Handy/Smartphone erinnert. Gäbe es da theoretisch eine möglichkeit, so etwas wie einen Bluetooth-Empfänger anzubauen? Fand die Idee ganz interessant.
Smarter man than I... if you have all the tools this man has and understand what he is saying, you probably don’t need this video in order to make your own radio. I think I will stick with legos for now.
Great video! I would just recommend one thing. Please fix the code in your Arduino sketch so that the SW pin mode is INPUT_PULLUP. Without this pin mode the user observes bouncing between FM and volume on the LCD display because SW is being read incorrectly in the pin mode of INPUT.
I'm looking for an RM Receiver with an aux output, such that I could connect to a newer speaker, or cell phone, or whatever and play an FM station. This guy would know where to get that.
I would love if someone made a modern tube radio,I like the sound tube radio give,it a warmer ,smother sound,that's why they make high end tube steros and guitar amps.
Dear friend i m just kid in digital electronics, can u please suggest any site to learn programing language & Tools.. and this project were awesome... i love it.... 100 Likes from my side....
Super **** (Wort nicht angebracht) es Projekt! Danke für die Demo. Ein DAB+ Radio steht ganz oben auf meiner Wunschliste, den Chip hätte ich schon, leider happert es noch mit dem Datasheet ;D und einer I2S-Integration. Aber Adafruit und die nächste Generation Arduinos (MKR1000) werden das schon lösen ... Danke für das Super Video und ... bleibt kreativ!

Please don't be fooled by the text put on the encoder board. It's not Clock & Data - It's two phase signal, 90 degrees apart. It's called quadrature encoding.
I tried building one when i was 15. It was a huge failure, but with your videos i am comfortable trying it again.
Your videos are just great. While many of these things are above what I can do, I absolutely love watching you put them together! Thanks for sharing!

I watched this video a bit after it came out, and still come back to it since it's my favorite video by far
I remember watching this 5 years ago, I understood little to nothing. Now I understand everything 😄
Nice project. I agree that the the prebuild class-D amp would have simplified the final circuit, but it looks like a good build nonetheless. Thanks for sharing.

Why can,t you make with the single Sony IC 1619 like one with LCD display with auto searching incl Bluetooth n recording ability.
Congrats! Your English is getting better in evry video! That is awesme! Keep making videos and keep sharing your creativity with the world! Good job!
My uncle taught me years ago. Most scientific references are native German..Cheers!
Keep making awesome, yet simple video's. I love them. They keep my curiosity's fire going!
Scott is really great and his work too.
Großen Respekt an dich,

keep doing what are you doing Scott ! looking forward to Part 2 !
It's been seven years, what you are doing now sir?
This is a great practical gift because of it's classic interface.
+subsynchronous To me "classic interface" means a needle moving in front of a dial. I kind of expected the whole thing to be analogue to be honest.

You provide such a great merit to your viewers. Much appreciated.
Thought you used a metal Military Ammo Box to protect from EMP ! Thank you for the video ! tjl
nice work
NIce video as always. Man I sure have a long way to go, I am still stuck on trying to bias these freaking transistors!
it are needing more one amplification stage and one auto-gain circuit interconnecting (monitoring the 2nd amp. stage and inserting on the first stage) the two amplifier steps
If I could just LIKE this video multiple times ...
Hi! Great Scott I appreciate all the knowledge you spreading around the globe. May you please make fm radio that can play mp3 as well.please.
I enjoy your videos, and I think making your own video projector could be a great project.
I adore you because you make a lot of beautiful projects
I respect you a lot because you're a very good boy have you got the skills to do all these things that are very interesting
and then every time you get a new video I happen uproar at my house
Make very interesting projects and I wish you grow up you become a star
I love watching your videos man great job again from great Scott. Thank you sharing your ideas and projects.
I guess the good ol' days of building your first crystal controlled radio has gone the way of the dinosaur! :)
crystal? what? lol
Man upload more, your videos are great
Wow! Very nice design
Nice Radio...
Next project pherhaps a DAB+ radio ?? :-)
i really love your channel even i understand nothin, keepgoing mate
That Was Awesome Dude. Keep up the great work. Nick.
Great video, thank you. Excellent content and skill level with good video and text. I had a lot of pleasure to watch it.
Thank you ;-)

I really like yours projekts....but can you make a video about making door lock using arduino,LCD, servo motor and keypad...?
Is there a place I could get the schematic for this radio and wanted to know if you have any plans in the near future do anything with a ham radio.. Would love to see a step by step guide of how to build a 2meter SSB radio.. I could probably find something on the Internet.. But love the way you put your videos together. Thanks again and keep up the great work
I'm very motivated by your videos
Thanks mate. I can use for college project..
How about you try make something that is understandable for arduino/electronics beginners aswell?
As a beginner you won't be able to do a radio
DreadSage 27 Damn it
Morgan Freeman how about you shut the fuck up and learn
There are a few basic videos at the beginning. Look for those.
I like you use rotary encoder. Never see something practical way before! //Maybe use ATTiny to calculate length of encoder and send data via i2c to make turning smooter. ;)
It may also pick up broadcasts from NOAA stations' emergency news broadcasts.
How many arduinos do you have in total? :P
I have been watching your videos and you use them a lot! Love your videos :D
AWESOME DUDE!
HOW I WISH I CAN BUILD THE SAME...
Great Scott! A Radio!
Yes, I guessed it as soon as you've uploaded the schematics of the case to Twitter....
Stay creative and we will see you in next time
GreatScott, how are those tiny 3W 5V PAM8403 amplifiers so powerful? They only output 3 watts of power, but are extremely loud...
+TeaDrinkingIlluminati 3W is already quite a bit. If you want to learn more about class D amps then you should check out Afrotechmods channel. He made a great video about those.
+GreatScott! i have one of those PAM8403 amps and they are awesome. Thank you for the project you helped me out with mine big time.

Glad to see someone else building a great product out of salvaged parts! Nice Work.
It would have been cool if you implemented a Bluetooth module so that you can use it as a Bluetooth speaker as well
You are a Genius
dude you're a genius
Awesome work! Are you going to do a follow up on the oscilloscope? Some kind of portable project?
+Sjaak Benzia Maybe. No certain plans yet.
I though you were going to actually design an RF circuit, I was a little disappointed, but still nice video to watch:)
omg, this is going to be my new project for sure!!!
Thanks for this nice idea.
Do you think this can also work on other 'frequencies?
Thinking about weather sat, airband, or community service channels ?
sehr gute DIYs, hab Abo da gelassen...
Excellent project.
love that Gossen meter
Your videos are very helpful an fun keep going
thank you on making this project, as you promised me so :D
Hay thats a great job but to many wires be nice to keep it more basic so people do build them, cheers
Nice work. Could you make a DAB Digital radio to? Since they are extremly expensive now and my country will shut down FM next year.
It seems like a lot of work when a charity shop digital receiver that is RIP could be brought back to life and modified ...
Wouldnt that small voltage regulator module eventually get to much power pulled threw it? Then again since you are using a single cell lithium battery it seems the circuit isnt drawing to much power.
I used one of those small modules before and it caught on fire.
Looking back, maybe i shouldnt have had it assist in powering a 100w led....

You can go to the Instructables website and see the circuit schematic, Arduino code, and parts list: www.instructables.com/Make-Your-Own-FM-Radio/.
