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.

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.

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.

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!

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.

@alexw9167 3 жыл бұрын

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.
