Thank you so much! Yes! This could be a great movie prop. I could see it in blade runner, minority report, mission impossible, something like that. I'm a big movie fan and I think it's fun to create props so I will be making more!

Oh I didn't know about that. I would like to hear the comparison. Thanks for letting me know.

That's great! It took me a lot longer with the razor blade but it is so amazing that it actually can work.

It might work but I hear most people recommend the 1N34A germanium diode for best results. If you try it and it does work, let us know. Thank you.

Yes this will only recieve AM stations.

Yes I am impressed with how quiet this fan is. It is a good addition to have. I am glad you liked this so thank you for the comment!

Good to keep in mind but I looked at my sink and I have plastic pipes but it still works. So I was trying to make sense of that. Maybe there is enough metal in the whole sink for the current to flow to. Or maybe the current can flow from the pressured water in the pipe down until it eventually reaches metal or the actual ground. Not sure but I think mine worked ok. An actual metal rod stuck in the ground might be an alternative for troubleshooting.

Thank you for saying that!

Wow that sounds like a fun father and son project! Yes I hope I revitalized peoples interests in this great educational and entertaining project.

I'm adding a layer of oxide to the steel. This method is called a fox-hole radio and there are some great explanaitions on how they work online.

Haha yeah I guess you can really use any non conductive items. Makes you feel like a real life Macgyver.

Yes I heard about the capacitor trick but I was happy with how clear mine sounded but I guess it kind of depends on how close you are to the radio tower. I'm glad to hear this brought back good memories! It's interesting that the technologies of today, 3D printers, can be used to make technologies of the past, crystal radios.

I'm glad to hear that! :) Yes it was by random chance I saw those spring cord ends and knew it would make this project much easier to build.

Thank you for saying that! I spent a long time on this so I'm glad it paid off. I hope to make more videos on here.

Thank you for saying that! It sounds good too haha.

Thank you! Yes I always look for inspiration and never know where I find it.

Thank you! It is designed that way and it works great for me.

Thank you for saying that. I'm glad you like it.
