This is a tutorial on how to make an alarm mod to my casset player safe. If you have not seen it, see that instructable first. There are notes on most of the pics.

Step 1: Step 1: What You Will Need

You will need:
DIY casset player safe
Wire Strippers/ Cutters
Soldering Iron
Solder
Hot Glue Gun
Hot Glue
Stand ( or something to hold the wires )
Wires
Screwdriver
Spring Loaded Switch ( commonly foung in cd/ floppy drives or purchased for 1$ )
9 Volt Battery
9 Volt Adaptor
Buzzer ( 5$ )

Step 2: Step 2: Begin

Begin by removing the front panel, by removing the knobs and unscrewing the side screws.

Step 3: Step 3: Remove Switch

Remove the volume switch by unscrewing the nut. After removing it, cut away all of the circuit board.
Sorry about the bad picture.

Step 4: Step 4: Test and Solder

You will need to test which leads will allow the full current through, normally it will be the 2 in the middle. After you have found them, solder a wire around 2 1/2 inches long to one lead.

Step 5: Step 5: More Soldering

Now solder the negative wire from the 9 volt adaptor to the other lead.

Step 6: Step 6: Soldering

Now take the long wire, and solder it to the momentary switche's first lead. Then solder a long wire to the positive end of the buzzer and to the second lead. Next solder the negative buzzer lead to the switch, and the other switch wire to the 9 volt adaptors positive wire.

Step 7: Step 7: Installing

Put the switch back in place, securing it with the nut. Glue the buzzer near by. Glue/ screw the other switch somewhere near the top edge of the case, so that the cover will hold it down. Glue the wires out of the way, and re install the front plate and knobs. make sure the volume switch is off, and plug in the battery. if done correctly, it will be somewhat like this.

Step 8: Finish

Congrats! You now have an inconspicuous safe, with a secret alarm!

Step 9: Adittions

You can also expand this alarm system, by adding another buzzer, lights, shocking device, or even a chip with your voice on it. ( im going to try a shocking safe by using a barbacue igniter, ill post it if it works )

Step 10: Video

This is a video of the safe in action.
