Make your own FM Radio - Part 1
video description
I tried to complete this project on a breadboard but faced couple of issues.
1. First of all schematic and video are in conflict and do not prevent bouncing on rotary encoder. SW button do not work properly with a 10k pull-up and 100nF debounce capacitor (also on +5V, which was shown to be connected to ground.
2. I tried to wire an LCD the same way and with the same pins as shown in video but LCD does not show anything. It only allows me to adjust contrast.
3. PAM8403 works considerably OK but the schematic provided for TDA1905 also fails. I must have checked the connections 10000 times but all i get is screech. (Specially the connection from pin 6 to 10k resistor connected to pin 1.
4. Maybe it is the way i powered up my radio (both batteries, adaptors, 18650 etc) but allthough the codes and the wiring and even the components are the same, lcd screen and rotary encoder fails.
I hear the radio stations when i power the system up but cannot properly adjust the fm stations and volume.
Any advice?
Thanks.

not having an electrician in your group cuts out all modern technological repairs on all your electrical tools
including, but not limited to;
radio's, flashlights, computers, phones, drones, toys, generators, modern cars, helicopter and other militairy vehicles that use alot of electrical parts, NVGs, scopes, buildingcircuits, elevators, powerlines, rocketships, computer attachements, remotes, card readers, televisions, chargers, security systems, electrical doors, car keys, drills and saws.
then you also have IT, which deals with the Artificial Reality, called the internet and also coding.
if your reading this. then it means you are inside of it right now.

That's a really nice looking radio. I always enjoy your videos. You know I think for Schnitz and giggles you should put a speaker on the top two. It never seems like you're in the right position for the speaker and that way you'd have one blasting forward and one blasting upwards. Of course it would shorten the battery time but probably not by much

The dial and display on mine has a horrible refresh rate, even when i change the delay from 500 ms to like 2ms. What am I doing wrong? Using an i2c driven display, but i2c shouldnt give 1 second latency

Smarter man than I. if you have all the tools this man has and understand what he is saying, you probably dont need this video in order to make your own radio. I think I will stick with legos for now.

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

I don't understand the coding part or a lot of the lingo going on but cool I still am interested in building a radio to see if I can build one
