I've had it with the worthless FTC, and want to take matters into my own hands. I want to build a device that I can activate over the telephone lines that will , at least, send a DEAFENING tone to the caller, or will, at most, destroy or cause damage to the callers telephone/computer equipment. And I couldn't care less about legality responses to this post. I'm seeking technical information only, and how I may use it is my responsibility.
