I recently signed up as a new member on All About Circuits and I hope that I will be able to contribute to this website and the forums as well as learn a lot about electronics in general. I am (currently) a soldering and electronics amateur though I believe that will change in the future.
I have several questions about the crystal radio project I am working on and if they are answered hopefully I should be able to complete this project. I hope I am posting my questions about this project in the right place but if I am not please let me know. I will upload some files to show how much progress I have made on the project so far including pictures of the soldering, schematics etc. Since I am still learning how to solder, if you have some suggestions on how I could have soldered the project better feel free to tell me, but overall go easy on me in terms of the quality of my soldering work .
I think I soldered most of the components into the correct places (the outlines on the board made it fairly straightforward) though I am iffy about some of them. I am fairly sure I soldered the variable capacitor the right way up but if I haven't please let me know. I am particularly unsure about some components such as the earphone jack; did I solder its leads into the correct holes? Also I am uncertain if I soldered the ends of the antenna coil correctly.
In particular I wasn't sure about how to ground the crystal radio; do I need to solder a copper wire to the big unused hole on the PCB? And then attach that wire to some sort of metal pipe driven into the ground? Is that even necessary? Components for grounding was the only thing that wasn't included with the project so I want to confirm how to ground the project and what components I will need. By the way I would ideally like to not ground the project outdoors so if you have any suggestions for how I can complete the project and use it only indoors please let me know. Any other general comments about completing this project would be great too.
Thanks, and I look forward to your replies!
