what singnals is it detecting i made on with three transistors and it lights when its by a tv im prety sure its static for three transistors

dude please send circuit for this ;,i ma very at it...........

[MsSheryl143]

can i have a schematic of this circuit?...please,.as soon as possible can i get 2morow if u read this!!!!...tnk u...

can i get the schematic for this? plss send it on duex_gabriela21@yahoo.com tnx...

[barbalote2]

where can i get the schematic for this?

thanks

High Voltage generators, Electrostatics, electromagnetic field, microwaves and RF signals are sources that activate this device. Cool! Very interesting!

hello h2d6.. can this circuit detect unintentional radiation that emit from ict devices?

[misqisz]

hello h2d6... would u share your schematic with me?

if u are feel free.. just email me at :

citra_malaya@yahoo.com

thankss

may i know the schem. dia for this and items list?

[sbatrouney]

can you construct a rf detector i will be interested to purchase from you

[h2d6]

@sbatrouney

sure, we are working on it.

[Drobnjak1]

Awesome stuff mate. I am in the process of building a RF detector myself. I am using a LED bar graph display to indicate the levels of RF detection. Also I am using a micro Amp meter as an alternative display method. Would you mind sharing the schematics with us? That would be appreciated. Cheers

@Drobnjak1

Sure, can you give me your E-MaIl address ?

[Drobnjak1]

@h2d6

I received your schematics, thank you again. However, a few things that (to me at least) do not make sense about this RF detector.

1stly, you do not have an RF detector diode at all.

2ndly, you have four transistors in Darlington setup without any biasing at all.

3rdly, you somehow have managed to amplify a signal of at least 900Mhz even though at the end of your last (fourth) transistor your bandwidth would have been no better than 1Mhz

[Drobnjak1]

4thly, how do you get a micro amp signal to turn on your first transistor and consequently the other three?

[h2d6]

@Drobnjak1

sure you have made a mistake. this is not an hf rf detecter. no need to filt carrier wave

or anything. just showing the performance of four transisters connected in classical darlington.if you are considering something like a rf detector or field

strength moniter,you better use high frequency tansister or suitable i.c. (ive made a one for vhf range) . this unit will also work for 27mhz amt freq:.use two in4148 in duo directions at first amplification stage in BE junction. simple..

Very nice detector! Do you have a schema of this circuit?
