Introduction: DIY Cell Phone Detector.
When thinking about cell phones. I got a idea of making a circuit which is capable of detecting the phone's call and message. It may be incoming or out going.
The project made is a cell phone detector which is capable of detecting the 2g,3g,4g cell phones and its signals.
This project is cool to play with and very useful to teachers so that they can find the student's who are using cellphone inside class room.

Step 2: Find Schematics.
Step 3: Place Components.
Place all the components on zero PCB as shown.
Step 4: Solder Components.
Connect all components and solder them according to schematic .
Step 5: Power on Your Circuit and Test It.
Now your cell phone detector is complete.Now you can detect active cell phones.
