Phone Recorder

at 8:47 am. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks


Our friend Muris from elektronika.ba has sent in his latest project. It is a Phone Recorder that records all phone conversations in the entire house. There is also no need to turn it on or off, it monitors the phone line and starts recording as soon as a phone is picked up. It stores all of the conversations in MP3 format for easy storage or review. There is an archive available with schematics and code just in case you would like one for your house.

“How does it work?
The hardware-part consists of:
– audio pickup circuit
– phone line status monitor
– microcontroller to send the phone-line state to PC using USB (serial<->usb)”

    What’s a phone line?


  2. NatureTM Says:

    It’s the little ethernet plug that connects to ppl’s dsl box. The DSL box turns little ethernet plugs into normal ethernet plugs.

    Hey Pete,

    A phone line is a technology that fills the gap in between the can and string method and the cell phone. It is inferior to both of these methods though since it is strictly location based.

    @ pete
    LOL… pretty much sums up the level of tech we have today…

    I really need to get one of these! I wonder how much space it takes to record a lot of calls.

    @ multiple monitors

    planting one of these in your gf’s house to secretly record her phone conversations will result in her leaving you 😛

  7. NatureTM Says:


    Convince her to switch to voip and then just log her packets. Now you get her voice comms and her naughty facebook info!

    I’m kidding though, don’t use your powers for evil. As some great somebody once said, the measure of a person is what he or she does after being given some power over another.

    Is there a way where we can track the calling phone number ID also?

    Thanks in advance,

  10. Alan Parekh Says:

    Hi Moe,

    No, you would need to build it yourself.
