Subject: Re: Experiment Leo Schatzl&lt;P>Rotterdam, 3-09-1998&lt;P>Some suggestions that might be of any use to possible further experiments involving vibrations.&lt;BR>
A few years ago I build a device named the "Trilmachine" (dutch for chaking-machine), the aim of this project was to put hole buildings into motion thrue heavy&lt;BR>
vibrations. The main targets were appartments, by bringing these into motion the habitants could discover more about there self and their neighbours. The&lt;BR>
ultimate result, destruction of the building, wasn't the primairy goal.&lt;P>Well....  device,&lt;P>It was a simple 220volt 1200watts motor wich was connected with a gearing to an axis (30mm) hang up in two bearings, a 500 gramm exentric weight, and an&lt;BR>
electronic-motor controller. With the little vibrations I could, ones found the right frequentie, even put the floor of an old energie-factory into motion. The&lt;BR>
device turned out to be very reliable but a bit slow if you want to change the frequentie.&lt;BR>
Later on I build a new one wich was even smaller but also did quit well. This one was for rent in a machineshop for a while but..... nobody did.&lt;P>I also did some test using other technices&lt;BR>
- - There are very small pneumatic-cylinders wich can handel a pretty fast frequentie. The side equipment is a bit more complicated so is the required&lt;BR>
contruction.&lt;BR>
- - There is some contactspeaker named "Bass-chaker" car-audio-freaks use&lt;BR>
it. This is a speaker without a conus it just chake's. You won't hear anything unless it is atached to a plate or something. I used it to get some sounds true&lt;BR>
a thinn wall without blowing my ears out on my side. It handels the average bass frequentie range.&lt;P>Marnix de Nijs &lt;marnixdn@xs4all.nl>&lt;P>&lt;P>&lt;BR>
