In the Instructable i will show you how to make 2 different phone taps that can be used on any house phone.
The amplifiers used in this instructable can be taken from old Wall outlet chargers. The kind you charge a phone with.
BTW if i can ill get a better camera instead of taking picks with an ipod and make a phone tap that clips onto the wire and pins connect to the wires and it will have an internal recording module with a micro SD card slot and run off the power of the Phone line itself. I have everything set up already. i just need the module.

Tools

Open the case to you DSL filter. Be careful not to break it because opening these little guys is hard if you dont have better tools.

Separate the Guts of the Filter From the Casing
