Back at school I built a little trap in order to fool some other pupils.
At first I took apart an old CD-drive and removed the laser-moving unit:
the laser unit |
The laser unit will be used as our trigger mechanism.
Just solder a connection to the motor and add a needle to the moving part.
The needle will move forward and pop our waterballoon.
I used a laser and a photocell to build a lightbarrier which would activat the trap.
The light barrier was placed across the pupils’ common room.
Here’s the trap’s schematic:
This is the laser and the receiver (both are battery powered) :

If the laser beam is interrupted the relais will activate the CD-drive-trigger and pop the waterbomb right over somebody’s head.
Here the mounted trigger armed with one waterbomb:
And here the first victim (of course with slowmow) :
So this is one way to have fun with your old CD-Drive!
thats a pretty interesting idea. seems hard to do though.
If I could pull this off, I'd do it in so many places. Somebody should mass produce it.
Profusely
Hahahaha, very simple design – Nice idea 🙂

Good stuff!
Nothing is better than a mechanism that make we laugh at other people.
Quite sophisticated for what it does, but brilliant nonetheless! Electronics were always meant for entertainment
Genius, simply genius. Kudos to you.
This is absolutely brilliant. I wonder if you could do this on a larger scale, and set it up for a cup of water? A Bucket??
WHERE WILL THE MADNESS END????
