I need some cool effects for my halloween party, so I came up with a spooky toilet that wispers "I will kill kill you" when ever you open the toilet lid.

I reused the electronic of a cheap toy called "Digitally Recordable Motion Activated Visitor Welcoming Door Chime Frog". Its a tiny plastic gadget you can place at the door. Normally it is used to say "Hello" to your guests when they pass by, but you can record your own message. I took out the electronics and mounted it to my toilet seat!

Here is a short video to get an idea:

Step 1: Tools and Material

  • "Digitally Recordable Motion Activated Visitor Welcoming Door Chime Frog" (you can order it at Dealextreme for $4,50), but there are similar gadgets on the market.
  • some handy tools
  • hot glue
  • Dremel or rotary tool

Step 2: Record the Sound


First record the sound to your device. There are some free "Horror Sounds" at SoundBible, but so many other sources on the Internet. I used the "I will kill you" sound from SoundBible. Its published under Creative Commons License, so you are allowed to use it for your projects.

Push the record button on your toy, press play on the website and record the sound of your choice

Step 3: Open the Toy, Get the Electronic


Now its time to take out the electronics. Open the gadget using a screwdriver. Remove the circuit board from the battery case. Now you can cut out the battery case using a Dremel or a similar rotary tool. Remove all the other components from the case. Most of them are just hot glued to it. The only component I did not got out was the LED, so I simply desoldered it.

You may also desolder the record button and the microphone, but I left it to reuse the electronics for later projects.

Step 4: Prepare the Toilet


Now its time to mount the electronics to the toilet. I just hotglued all the parts to the bottom of the toilet seat. The light sensor, "looks" at the backside of the seat. So if you open the lid, the sensor gets light and starts the playback.

Step 5: Test It and Horrify Your Guests


Turn on the circuit and close the toilet. Open the lid and test it. If everything works fine, cover the electronics with plastic foil to prevent accidents.

I hope you enjoyed this Instructable. Have a look at my other halloween projects: Halloween Latern and Santa Mumy. And dont forget to share your thoughts and ideas in the comments!

Creepy Halloween!
"I am the Butt Ghost, I will eat your butt."
Looks like someone has too much time on their hands! <br> <br>But, it looks like something fun do to do.
What would also be funny is to program the message to play random Portal Turret quotes. How funny would it be to lift the toilet seat, only to hear &quot;I don't blame you&quot; in a high-pitched, robotic voice?
Yes defenitely, but not possible with this device. It's just designed to store one message. But you could use an arduino with a waveshield, or a modded mp3-player for that.
LOLROTF!
Creepy! I' be afraid to use the toilet after that. Perfect for Halloween!
