Thanks again to Paul for making this an open thread for peltier projects.
Here's the latest pic of my newt cooler. It gets less aesthetically pleasing as work progresses. But I think an endpoint is finally within sight.
I have placed a terminal strip on each inside face of the box; one for a + bus and the other (-). Radio Shack stocks these along with an optional strip fitting one side which makes all connections electrically common for each strip.
The next step will be to solder spade lugs to wire ends from the peltiers and the fans. One switch will activate the small inside fan (not shown). Both switches on will run the works. The box should be plenty crowded with wires.
