Make your own FM Radio - Part 1

[@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!

[@krouppi58]

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

[@kaumohlamonyane272]

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

meanwhile jinx could re-upload this and make a small fortune off of it. Thank you for all the work you put into your channel, you're awesome.

[@wilfredheggart2497]

+Immortal Android thank you

[@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.

[@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

[@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.

[@karimismail3734]

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

[@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.

[@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!

[@viking90706]

My uncle taught me years ago. Most scientific references are native German..Cheers!

[@quantummaster5814]

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

[@tubegor]

Scott is really great and his work too.

[@BinaryDNA]

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

[@lucyd_demon]

Großen Respekt an dich, Deine Videos sind spitze auch wenn ich nicht alles Verstehe. Mein Leiblingsvideo: Die LED-Bar!

[@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...

[@derp6632]

You provide such a great merit to your viewers. Much appreciated.

[@peepeeland]

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

[@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.

[@speedsterh]

As always, super interesting. You make the build look so easy, I'm jealous

It is simplified C

[@metrinshshotya]

[@spike4850]

[@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....

[@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.

[@peterthinks]

I love your builds. Keep up the great work!

[@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

[@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.

[@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

[@RenatoYamamoto481]

[@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]

[@XanderYTV]

I love these videos dude I just recently found your channel and have seen every episode within a few weeks haha.

[@greatscottlab]

+SShimon Thanks mate ;-)

[@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.

[@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.

[@TheIsraelGamers]

.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 !

[@greatscottlab]

+Sjaak Benzia Maybe. No certain plans yet.

[@printffff]

How many breadboards do you have?

[@greatscottlab]

+Howie Au Only the two. I hit my maximum there.

[@printffff]

I thought you would have like 20 or so breadboards flapping around so that you won't even care using the radio on breadboard :P

[@kyoudaiken]

What I don't like is the constant division of the videos into at least two very short parts. Is your internet upload bandwidth so low?

[@greatscottlab]

+BloodySword I really don't like this questions. I make weekly videos and the production of part 1 took about 30 hours. Just because a video is short does not mean there is little effort to create it.

[@The-Nil-By-Mouth]

At least it doesn't take months between parts like some channels I've seen

[@narpat007]

[@georgey7746]

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

[@mediasemua]

Is it possible to make a 200 mhz radio receiver project? Thank you for the video

[@beanlets]

What about the parasitic inductance? Did you take that into consideration?

[@orca1338]

Have you thought about 3d printing the case?

[@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.

[@masondaub9201]

On a 16 bit pic I got away with using a change notification interrupt on just 1 of the rotary encoder input pins. I wanted to save the external interrupt pins in case I needed them further down the line

[@pablo_costas]

I know your method is much faster but , why dont you make PCB with transfer method ? boards look better

[@mizuki4002]

Can I use another digital pot IC? I only have the MCP41010 on hand.

[@greatscottlab]

+Paulo Henrique I put it on my to do list.

[@SpartozZ]

Hey, cool project but i have one question: is that mono speaker producing stereo soud? i mean; both right and left chanels in that one speaker

[@greatscottlab]

+SpartozZ Yes, I mixed L and R together.

[@mp8072]

That's a really cool build, congrats! I have tried to do soldering of small parts but have a hard time because my vision is not that great and my hands shake a little. Do you or any followers have any tips for soldering small parts? And how difficult is it to create an etched circuit board for something like this ? Thanks!

[@alexw9167]

Heat the soldering iron up to about 310 - 330 degrees celsius. Use an arm with an alligator clip at the end to hold the component. Use another arm with an alligator clip at the end to hold the strip of solder flush against the metal contact point of the component. Heat the metal contact point with the tip of the soldering iron until the solder begins to melt against the metal contact point. This seemed to work when soldering to very tiny pins with very small spacing on an MCP4151 chip that I got from DigiKey.

[@akratooos]

Wow! Very nice design

[@simonlachsl]

Yes, I guessed it as soon as you've uploaded the schematics of the case to Twitter....

[@Ali107]

[@Mitrasto22]

It may also pick up broadcasts from NOAA stations' emergency news broadcasts.

[@OTGrus]

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.

[@EugenMihailescu]

Can we use a X9C104 digital potentiometer instead of MCP4151 ?

[@EugenMihailescu]

I've noticed that X9C104 is a 7-bit while MCP4151 is a 8-bit, thus double the digital steps. I guess that we could use the X9C104 pot but then we probably won't be able to tune all frequencies, right?

[@areg7182]

im pretty sure he uses that as the volume control.

[@emailausdrucker]

add more batteries please. i am thinking that this could be an awesome emergency radio. we had a power outage for a few days a few years ago. this winter a 12h outage at -30c outside. is that fm only or am as well?
