Carl: Excellent! What did you use for the lighting system, I'm dealing with that right now. I was using some 3v battery packs with small wheat bulbs but am now trying to go with a 5v phone DC wall outlet that attaches with a USB cord and the problem is adapting to 3 and 5 volt led lights.

Yes, I'd be interested in your lighting system as I'm thinking of installing some in the sternwheeler dredger under construction at the moment.

Thanks Doane and Les...

My lighting plans are very simple & uses minimal components.

The electrical schematic shows what and how I'm using a 9 volt power supply, the LED's and voltage dropping resistors.
You can add more lights and resistors and the same wiring for more lights...


I use copper tape strips as busses for the 9 volt positive side, and 9 volt negative side. I solder a resistor in between the negative side voltage and the negative side of the LED. The strips wrap around the interior of structures for ease of installation. Kind of like a GIANT circuit board.

The LED's are 0603 SMD (surface mount devices)....and run at 3.2 volt and have a 20 milliamp draw.(which is close to full brightness).

A wall wart 9 volt supply is connected to the copper tape strips. I use black and white hook up wire to interconnect everything.

The entire build was documented on another forum.
