Hacked Calculator Prank

Hack a calculator to make crazy sounds or say wacky things just for fun.

Step 1 What You Need...

1. A calculator
2. A device that uses a recording module. In my case I found a cheap automotive memo thingy that sticks to the windshield and allows you to record up to 5 different messages and play them all back. You could use a regular single sound module like one from Radio Shack.

NOTE: You will have to find a calculator that is thick eoungh to hold the module inside it's case.

just made one of these, but i used a circuit from a toy duck...I was able to fit everything in without any bulges just fine, it was awesome! I put it in one of the calculators you can borrow at my school right before the final exam, haha the teacher handed it to one of my friends and she turned it on and it started quacking and wouldnt stop! today the teacher was talking about it "somebody wired a speaker in there! very clever" she still doesnt know it was me haha Great hack!!

[rick.leasure]

I like this. It's clever. Almost as much fun as watching the Instructable was reading all the comments afterward!

[Evilthingamabober]

"YOU DUMB ****!" If only they sold these...

[Mr. Squishy]

"YOU DUMB ****!" That was one of the most funny messages!

[bassclarinet23]

You could also use music cards. Great prank!

[memyselfand1]

It does look a little fake; in the video at the end, the calculator body moves when you press the button. The board doesn't fit in with the other board and kind of gives the game away. Sorry, good idea otherwise.

[Kipkay]

Everything fit inside just fine regardless of what you think you see. Sorry to burst your bubble.

[wupme]

Yeah, you can actually see really good that it doesn't fit. And thats probably because those boards are made to just fit the calculator. They don't left any space for adding another board...

[micromuffin]

I did it, it fits just fine.

[Arbitror]

It really depends on what calculator, and what voice recorder!
