You have a good heart.
Excellent video! Today (2019) you can buy a stereo amplifier from china for a few dollar. The trick is to find sensitive microphones. The microphones for mobie phones in cars är great. Assemby boxes are also available from China.
This circuit, hooked up to a transmitter, is an excellent bugging device.
Your projects are very interesting, I subscribed :)
This circuit is for the deaf people.
Excellent work!

Hello guys ,i am trying to make mot spot welder.Does anyone know how to make it adjustable so i can control the current of a secondary coil(the buissnes end where electrodes are)?
zumbazumba1 You want to look for Grant Thompson, The King Of Random. He did a whole series of videos on MOT spot and stick welders. He also made essentially the poor mans variac (variable ac) device. Check him out, he's a great source of ideas.
Can i get this pcb or can you sell this kit . Please

What capacity is c1
how does this get around unwanted noises?
It will pick them up as is. Circuit at 1:00 does have a rather nice network R10, R12, R13 and C9, C10, C11, C12 to limit the bandwith, but large part of the unwanted noise will be in the pass band. It'll attenuate loud clicks and other noise, which is nice. Plus due to high gain, there will be static (white noise).
Hi
