Hi group,
My name's Mark and I just found this forum and it sounds exactly like what I need.
I'm looking to build a portable ,frequency specific listening device like the Gen-ear made by General Wire Spring Co. for finding water leaks underground.These things seem incredibly expensive for what they are.
I originally began looking at portable headphone amps typically used to plug into an electric guitar and go directly to headphones for private playing and, also a guitar equalizer pedal for effects, to filter the input.But,the pedal would only enhance the frequency I wanted while deminishing the frequency of the sound I don't want.
The Gen-Ear filters ALL frequency below 100hz and above 1200hz along with a press to hear button for safety.I would also like to incorporate a VU meter and possibly a portable audio spectrum analyzer to find peak signals along the line.
I graduated from an electronics school about 30yrs ago.Do you even use transistors anymore? I can read a simple schematic, solder like crazy and even fabricate a nice,sturdy container for all this.But, I could really use some help on the particulars of this project.
Thanks,Mark
