Re: what did i do wrong?



i appreciate the help, but i watched some tutorials on youtube & if i am not mistaken these things are for building badges/id's to allow entry of a personnel, unless there are other tutorials out there that i missed then i would love to see them, either that or i am much more in deeper trouble for being a total beginner in regards with these things so if there are links of these rf modules sweeping signals/frequencies/radiation then i would most definitely be more grateful than i already am. thank you all so much for trying to help me,...

Re: what did i do wrong?



yes, but wired cameras are way more easier to spot with the naked eye than wireless ones, unless there are now wired cams that are as deceitful as its wireless counterparts.



may i please have links? thank you so much...

Re: what did i do wrong?



thank you. i will give it a try, but do you have any suggestion for something hand held? something that can be used for counter surveillance? e.g. sweeping hidden cameras, etc?...

Re: what did i do wrong?



my end goal will be the following:

1. try to get some legitimate 1ss86 diodes
2. try to detect/locate the signals of pet microchips which are:125 kHz, 128 kHz, 134.2 kHz
3. at least try to detect the signal/frequency/bandwidth of any cellphone which from what i read are the following:

Re: what did i do wrong?

first off, thank you so much for replying, i really appreciate it. any other alternatives aside from a spectrum analyzer? something handheld, something similar that can be used for counter surveillance? i sincerely apologize for taking some of your precious time. again, thank you so much for helping out

Re: what did i do wrong?

do you have any suggestions for a legitimate signal/rf/radiation detector? i mean, an already built one that i can buy? maybe i can start from there and try to strip it & maybe figure out which is which

i tried to make three signal/radio frequency/radiation detector (please tell me if there are any differences between the three since i dont really know what i am doing), but none of them worked. what did i do wrong? is it me? is it the diode? the capacitor? the transistor? the coil? all of the above (i hope not)?

in this one, i read in some of the comments that it is fake or does my coil need to be a 24 awg?

in this one, i suspect that my diode was not what it was...

hi, i am here to ask questions & learn. thank you
