I've completed an evil little project, though not very useful.

The Sanity nullifier

The purpose of this device is a bit evil. Oh well, sue me. I made it as a yoke for the first of april and many more days to come.

A brief description:

The device beeps a short beep of a very annoying frequency in random times. The time between beeps is anywhere within half an hour to nine hours.

Point:
The subject of your devious device has a flat/house. Put the beeper inside the house, and when the first beep occurs, your victim will just wonder about that what was it. When it occurs again and again he will try to locate the source. After checking all cellphones, smokealarms, battery powered devices in general he will be clueless as to what is causing this. The beeping will be a mystery as long as the battery lives. Or it will drive him nuts.

Instruction:
1. Activate the device
2. Hide the device
3. Don't stay around to watch the fun.

It beeps in random. Where the time between beeps can be anything from 30minutes, to 9hours and 30minutes.

The schematics and sources and all you need is here, on my page:

Oh no, be present! Must be present to observe. Preferably with large numbers of people. LARGE numbers. Throw a party!

But coach everyone not to even flinch when they hear the sound. By the end of the party the recipient with the now nullified sanity will think they're having auditory hallucinations.

(The real fun is to see if they try to convince the first un-coached person that they're just hallucinating when they ask what the weird sound is.)

This is a strokagenius, daqq. Must build one!

If you build it, would you mind sending me a photo of it? I'll post it on my site, with a link to you and all credits to you ofcourse...

Hmmm... doesn't one of the PCB services offer something like up to $400 free for your first order? Someone should order a huge bag of the SMT boards, and spread them around...

I think that you need to speed up the beeps. Once every half an hour I could live with. Now every 10 minutes (approx) would really annoying.

Have fun!
