Two or 4 four-axle Piko wagons from Reko (or the other way around) should see a light...
Since these cars have toilet compartments with frosted glass windows, the electronics were placed in these compartments.
To do this, the floor of the toilet compartment had to be removed.
A switch with 2 positions was used for the interior lighting used. With a further switch with 3 positions can be independent of the interior lighting, the tail lighting can optionally be on one of both ends are switched on.
A small hand-flexed circuit board is used to hold the components and to wire the peripherals.
The circuit board is attached to the floor of the car with 2 screws on such a way that it also fixed the LED socket. The switches are on the left edge of the board connected. 2 solder pads are used for mechanical attachment and contacting the stepUp switching regulator (minus and out-plus) via 2 stiff copper wires. In-Plus is contacted with stranded wire. For connection the 3 LED circuits are provided by a 4-pole pin header. On the right is the battery chamber mounted for the accumulator.
In the meantime, the switches have also been connected.
Both switches have 2 levels. One level is used to switch the negative line between battery and switching regulator used, the other level for switching the minus lines of the 3 LED circuits. So is ensures that the switching regulator only loads the battery when an LED circuit is switched on.
The gap between the frame and the body is due to the fact that the car is not yet screwed shut.
Since the lights tend to fall out, they were on the occasion fixed with glue. The LEDs were connected using small ones flexed circuit board pieces as solder point carriers.
This board carries the two SMD resistors for the train circuit LEDs and is used to connect the LED strip and the (solid) cables the tail-end LEDs.
Here you can also see that the self-adhesive light strip of the interior lighting is also attached with wire clips.
The cable is now connected to the electronics:
Sometimes slightly blurred without flash with interior light ...
...and train end...
and now switched off on the umbilical cord of the charger.
The cut-out floor of the locus compartment:
could not be placed in the middle of the car unfortunately because there was no space. But they do not hinder the bogie.
...with wiring of the switches
with interior decoration.
This meant that several short LED strips could be installed individually in the compartments and connected by means of jumper wire. The connection of the Train end LEDs are made via jumper wire too. A couple of plasters off Textile tape fix the wiring.
Here the self-adhesive LED strips were additionally secured with wire clips too.
And ready to assemble:
And now also with the roof on:
