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.

@SaadouneZinji 4 года назад

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.

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

@karimismail3734 8 лет назад

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

@krouppi58 8 лет назад

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

@KennethTanFotografie 8 лет назад

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.

@rawux1228 7 лет назад

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.

@DaleHawkins 8 лет назад

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.

@tactfulyeti4091 8 лет назад

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.

@prashanth105 5 лет назад

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...

@everythingquads 8 лет назад

Another awesome video. Thank you.

@InfinityArcane 8 лет назад

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 4 года назад

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

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

@emersonsrandomvideos248 8 лет назад

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

@Beall619 8 лет назад

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....

@ParanormalBusters 5 лет назад

Does a tinny am FM kit exist that can automatically scanner through all the radio stations at one button touch

@TwitchRadio 8 лет назад

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

@ssbotrodriglez 3 года назад

Can I use this to build a shortwave radio transmitter? Like a walkie talkie or something like that

@-HustleUnion- 8 лет назад

can you do a video on how to make a analog VU meter that has a good response i.e. tune to a certain frequency so you can see mids, lows, and highs separately? I bought a DIY kit from ebay, it works and all but I'm not getting the responsive bounce of the needle that I was looking for instead it reads the total signal meaning the needle doesn't bounce it kinda just moves around in the middle slightly to show you the what the output looks like

@SethyPie07 5 лет назад

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.

@knightsbliss6889 5 лет назад

okay so i have a Haynes retro radio kit is it possible to use that basic circuit and improve upon it with your setup?

@Nardo_Agrimedia 8 лет назад

@leroy0053 8 лет назад

@shoaibakhtar2484 7 лет назад

can you tell me where I need to connect the ground wires in the schematic?

@azacink 8 лет назад

@n0ukf 7 лет назад

For an upgrade to this idea, does anyone know of a source where I can get an HD radio chip ON A BREAKOUT BOARD? I can find HD radio chips but I have only found the surface mount chips alone, not mounted on a board like this one is.

@simonlachsl 8 лет назад

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

@Charlie90071 8 лет назад

I see there is a stereo output at the FM Module. Have you just used one of the channels or did you converted them to a single mono output somehow?

@subsynchronous 8 лет назад

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

@somitomi 8 лет назад

+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 8 лет назад

+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 8 лет назад

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.

@SianaGearz 8 лет назад

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.
