Maybe your metal fillings aren't amalgam or silver, Lucille Ball apparently had amalgam fillings and it was reported she heard AM radio and Japanese spies transmitting.
Do you think a transmitter which covers small room be able to generate enough signal strength to make metal fragments...
Maybe it is because you didn't have any metal fillings in your teeth or in or around your skull, maybe it was just radiation without any modulation, had it been amplitude modulation, you might have heard some sounds.
Here is a link of AM sounds being heard through weed burning up near an AM...
When I searched for it on the net, all the diy projects were frequency locked projects, so I think mentioning AM transmitter would also give information about the frequency range, that is 530KHz to 1700KHz.
You can go to any shop which sells radios and some radios just mention AM and the...
Before actually asking here, I typed this query and searched on google: "diy multiband am transmitter" and all the results were about frequency locked projects. What search query did you use to find it?
Is there a way to get gerber files from the PCB layout mentioned in that PDF, so that I can...
How can I build a multiband AM transmitter?
All the DIY transmitters available online are for a fixed frequency, I want to be able change the transmit frequency covering at least 40KHz or more, I want an analog transmitter.
I think both were at fault, they seem to have regained some functionality after drying but still not working as they should. The charging case has dried inside out, and it's PCB seems to have dried out too, but it is not able to charge properly, it is indicating error with it's light.
I bought a pair bluetooth earbuds which are rated to be splash resistant, because of the on going pandemic, I washed the charging case and the earbuds with soap, while washing the charging case, it light up few times as if earbuds were inserted into them, after that I felt a slight warm inside...
So I tried a different construction, I made a frame with aluminum tubes, I've attached them with normal screw by drilling holes into them, over this I placed aluminum mesh on all six sides, top, bottom, left, right, front and back and I've attached this with screws by drilling holes through the...
Something along the lines of my suspicion:

Apparently memory buses do radiate EMF, strong enough to be received from few meters away, and the physical metal box doesn't block at all.
Now imagine what the traces near the audio chip can do.
If delay is the...
I have a mouse which used to show around 10-15 colors, since 2 years or so, it has stopped showing all these colors and is only showing few colors. So today I decided to repair it, and I opened it up, it has two LEDs on it's PCB, these two LEDs display more than one color, one of these LEDs...
If I'm seeing squiggly patterns are on the front and back at the same place, doesn't it mean the trace is on the top and bottom layers or extending through all the layers? Why would a path require traces on the top and bottom, wouldn't 1 be sufficient? I was reading an electronics textbook and...
That is impossible going by my experience.
Whether a metal can shield or not depends on it's conductivity, if it has low conductivity it's as good as transparent in the radio frequency and these cases have openings too. You have a smartphone which is so small it fits in your pocket, and it has...
I meant wireless signals, can they utilized to send and receive wireless signals? Not specifically built for wireless communication, but any regular IC which has transistors but can has transistors.
