As part of my final project in my EE studies I was thinking if it is possible to read 125KHz RFID tags with a smartphone. I know it is possible with NFC (13.56MHz) and I was thinking about implementing a 125KHz reader. Is there any antenna in a regular smartphone that can deal with these low...

As a part of an experiment in radioactivity, we placed an alpha particles emitting source (Am) and a sensor in a vacuum chamber, and measured the power (number of particles per time unit) for various angles of the sensor. Our goal is to fit a theoretical function to our measurements (power vs...

You are right. You can easily see that every input that includes B=0 gives a 0 output, when by the answer in red (A,B,C)=(1,0,0) for example should give 1.

Thanks a lot! This is really helpful. Well I'm just a 2nd year EE student seeking for some cool challenging project to start with (-:

Well, do you have any idea of what frequencies it probably emitting? I guess the phenomenon is basically what you mentioned, but I still want to get an antenna and figure out if there's any way to determine the differences between the keys. What type of antenna should I buy? Will regular RF...

Hi, I heard before that wired keyboards emits radiation when a key is clicked. My goal is to build a keylogger based on this phenomenon (for fun, of course). I've already seen some variations of this idea, but they were all using wireless keyboard, where it is much more simple to detect and...
