it is quite simple once you get a basic understanding of electronic components.

[@Dronebotworkshop]

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.

[@Alex0474]

You’re so right!

[@SaadouneZinji]

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.

[@Ghost572]

They do know how to steal designs though and copy them.

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!

[@kaumohlamonyane272]

I remember watching this 5 years ago, I understood little to nothing. Now I understand everything 😄

[@rawux1228]

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.

[@alankhaev8467]

I watched this video a bit after it came out, and still come back to it since it's my favorite video by far

[@krouppi58]

I tried building one when i was 15. It was a huge failure, but with your videos i am comfortable trying it again.

[@zaprodk]

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.

[@DaleHawkins]

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.

[@InfinityArcane]

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!

[@krishnakoushik6178]

Why can,t you make with the single Sony IC 1619 like one with LCD display with auto searching incl Bluetooth n recording ability.

[@quantummaster5814]

Great video! After this project, can you also make a tuneable FM transmitter?

[@KennethTanFotografie]

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.

[@karimismail3734]

Thank you Scott. Lots of work and high level of knowledge. No competition with that.

[@peepeeland]

Definitely feels good when one's circuit works the first time assembling it.

[@BinaryDNA]

Keep making awesome, yet simple video's. I love them. They keep my curiosity's fire going!

[@peterthinks]

I love your builds. Keep up the great work!

[@MrTranceFun]

Please show us how to make a DYI ECG device for monitoring heart electric activity. That would be AWESOME project.

[@SianaGearz]

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.

[@tactfulyeti4091]

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.

[@RenatoYamamoto481]

great video man, can you make a walk talk? would love to see that

[@VintageElectronicsGeek]

I guess the good ol' days of building your first crystal controlled radio has gone the way of the dinosaur! :)

[@ScibbieGames]

crystal? what? lol

[@subsynchronous]

This is a great practical gift because of it's classic interface.

[@somitomi]

+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.

[@subsynchronous]

+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.

[@somitomi]

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.

[@MaartenWeyns]

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!

[@emersonsrandomvideos248]

AWESOME DUDE! HOW I WISH I CAN BUILD THE SAME...

[@artifexmusic]

Scott : so you have to connect THIS HERE that there and this here. brain : what DA FK me : um what is he saying ahh fk it i still love watching these videos

[@henriquelausch6999]

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

[@Beall619]

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....

[@prashanth105]

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...

[@malcytull]

You are a genius ;-) thank you for all of your interesting videos, like someone else said, I don't understand much of it but it is really interesting.

[@TesserLink]

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.

[@albertanasoul]

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.

[@mustafasuzen22]

I love watching your videos man great job again from great Scott. Thank you sharing your ideas and projects.

[@teadrinkingilluminati9173]

GreatScott, how are those tiny 3W 5V PAM8403 amplifiers so powerful? They only output 3 watts of power, but are extremely loud...

[@greatscottlab]

+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.

[@dejanb2]

+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.

[@teadrinkingilluminati9173]

+GreatScott! Alright, thanks

[@tobimai4843]

+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

[@krisztianszirtes5414]

+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

[@leroy0053]

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

[@georgey7746]

I really like yours projekts....but can you make a video about making door lock using arduino,LCD, servo motor and keypad...?

[@pa3gtl]

Thanks for this nice idea. Do you think this can also work on other 'frequencies? Thinking about weather sat, airband, or community service channels ?

[@sirarnie9837]

NIce video as always. Man I sure have a long way to go, I am still stuck on trying to bias these freaking transistors!

[@simonedanna3241]

and then every time you get a new video I happen uproar at my house

[@simonedanna3241]

Make very interesting projects and I wish you grow up you become a star

[@akratooos]

Wow! Very nice design

[@kieferonline]

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.

[@greatscottlab]

+kieferonline Thanks ;-)

[@petermarshall1634]

Is it possible to tune above fm frequencies with the tuner chip?

[@hamdiaygun6372]

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

[@GregorOttmann]

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.

[@sanchiranar1613]

It would have been cool if you implemented a Bluetooth module so that you can use it as a Bluetooth speaker as well

[@nor4277]

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.

[@FXV56]

I would just tear appart a old radio take out its cip and componets and countinue with them

[@SethyPie07]

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.

[@notionSunday]

That was great.

[@eyreland]

It seems like a lot of work when a charity shop digital receiver that is RIP could be brought back to life and modified ...

[@mehmetedex]

*Suggestions for those who want to give a try:* 1- Use oled display for better visual experience and low power consumption 2- Update only the pixels needs to be changed rather than clearing the entire screen to get rid of jitter. 3- And do not forget to test and learn how all parts act when input is fed in, one at a time in this way its more easy to avoid errors.
