Light Control

The light control system in the Wunderland moved modelling to a higher plateau; a complete day is simulated in 15 minutes. More than 250,000 lights (LEDs and lamps) are individually computer controlled. This enables dynamic changes during the course of a day and can create a unique ambience.  During the past few years we noticed a rising demand for light control modules and thus we decided to develop our own light control system, the MiWuLight. Since production is not feasible within our budget we have stopped the production until further notice.

Information about MiWuLight

MiWuLight is a consequent enhancement of the techniques we developed to control any lit object on a model railroad. Each module comprises 24 outlets with a total load engineered for 2.5 to 3 Amps.

Variant 1

We deliver all modules with a basic configuration. There are different configuration sets such as for “fire engines”, “street lamps and signal lights”, “house lighting”, “bill boards”, and so on. These modules work on a stand-alone basis and do not need a computer to function.

Variant 2


Using software written by Gerrit Braun (probably freeware, once the legal issues have been sorted) for all 24 outlets, individual sequences may be edited and loaded into the module, provided you resist the temptation to buy the PC interface.  Each sequence may comprise 100 steps and be of any desired brightness. Transitions are infinitely variable (a light to be dimmed from 0 to maximum needing only 2 steps which means nearly infinite possibilities of light control are possible). Currently, we also offer EPROMs, meaning that the customer creates his sequences at home using the software, exports them, emails them to us, we will burn them to an EPROM which the customer in turn receives by mail. He/She then applies the EPROM to the module and the lights work as desired. However, the price for this service is still to be decided.

Variant 3


After buying the interface it is possible to control chain of MiWuLight modules (a simple 2-wire connection with long wires). In this case, the modules are controlled via computer.  Using the computer, for each of the 24 module outlets 5 sequences (100 steps) are programmable to be triggered by time, events, or on a day/night – basis. The day/night control can simulate 24 hours between 2–1440 real time minutes. The advantage of this method is that sequences are always loaded in the module and thus the lamps glow without flickering. So far, there are no other means (for instance, using ports) to achieve a flicker-free light whether you use Linux or Windows… This, variant (including the software), is the same technique currently used in the Wunderland.

Update: More than 50% of the manual is finished. Once Gerrit has completed this task we can go to production. We cannot give a fixed price as the ship-control system has priority and we have to find a suitable production location!
