Thomas Edison was a great inventor who, amongst other things, improved the microphone for telephones by developing a carbon microphone. In ways, more than one, Edison contributed to worldwide communication.
This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.
Talking about Edison, his greatest invention was not this carbon microphone or even his well-known phonograph but, it was the invention of the light bulb by far! Without Edison, we might still be using candles to bring light in darkness. That is why this radio has a light bulb as centrepiece. .. O yeah, this 100% optional attribute also looks kind of cool.
