NK8033 Pre-wired Gyra Light Kit

 

Product & installation overview:

This Lightning effect produces an output of varying intensity to simulate the changing shine of a Gyra Light for the LED connected to its outputs (solder points 3 & 4) when power is applied to the inputs (points 1 & 2).  The lighting effect is timed to accurately represent the slowly rotating beacon in a lighthouse.

Utilizing the industry’s smallest  microcontroller and associated voltage control circuitry, the total module with LED consumes less than 20 ma. This makes the NK8033 well suited for low power applications such as battery operation but can easily be powered by any well-filtered and regulated DC power source with an output of 6-18VDC. The very small overall size of this module will allow it to be easily placed in and around any structure, even in Z-scale.

 

Connecting the NK8033:

Installing the NK8033 is very straightforward. Because the module has circuitry on both sides, care must be taken to be sure that the components or wire solder points will not make contact with any metal object which could cause a short  circuit.

This kit is pre-wired with input power wires already connected. The red wire is for connection to +DC and the black wire is for connection to –DC (ground). These wires are pre-tinned for easy soldering  to your power source. Figure 1 below shows a close-up of the circuit and wiring connections. Point 3 & 4 are the outputs that connect to the attached LED. All wires are multi-stranded so they are very flexible allowing for easy routing in the model.

Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires.

 

                     Figure 1

The LED is a Ngineering N1022C high intensity Incandescent LED. It is quite bright and is constructed in a 2 X 3mm ceramic housing. Although the main source of light is out of its face (surface with the orange oval) it produces sufficient side-shine that it can be mounted facing up and  still project sufficient light from all 4 sides to illuminate the beacon area of a lighthouse model.

We recommend mounting the LED from the back by attaching adhesive to the wires near the back of the LED so adhesive is not placed directly on the LED. It is also recommended that whatever adhesive is used that it does not contain high aggressive solvents that could attack the insulation on the wires. Walthers Goo is an example of an “aggressive” solvent type adhesive. Elmers white Glue, CA (superglue) and 2-part epoxies are very safe for this type of mounting and will not damage wires or surfaces of your model in most cases.

If the LED is to be mounted slightly above a flat surface, we recommend cutting a narrow slot from the edge of the surface to slide the wires into position where the LED is to be located. Then gluing the wires min position will be very easy and hold the LED in place while the adhesive dries.

This completes hookup of our NK8033 Gyra Light module. We hope the added realism it provides enhances your enjoyment of the hobby.
