Doepfer

There are two major risks of water and electricity:

It is NOT the water in the basin itself, but the connection it can make 
to earth. The danger of the water in the bathtube is not the water in 
the bathtube, but the electrical connection to ground which is provided 
by the water, that is running through the drain to the ground.

THe other and more important aspect of danger of water with any kind of 
electronics is, that you will have wet hands and water is dripping 
around from your hands into the housing and will find its way to the 
powersupply. Then it will find a possibility to shorten 220 Volts from 
the next corner powerplant direct to the 12V driven modules. And I 
assume you worked hard for the money to buy them.


So my decent hint is: Remove the AC-Powersupply from the housing and 
install a connector (E.g. asymetric XLR) for +12V, -12V, and Ground.

Now you can feed this with any kind of DC-power. Either you build the 
original Doepfer powersupply in a separate waterproof housing, or you 
use some batteries or accumulators for it.

I once modified a a 3HE Housing for the usage as portable theremin. It 
uses 12 V Accumulators:

You may have to scroll down the left frame to find the pics with the 
accumulators
