D type Hooded Signal in Z-scale

There have been some slow progress in the development of signals for the Zity Edge Layout.

The newest signal is a D-type Hooded 3 Light Signal, modelled using Fusion 360.

The first D-type signal is assembled, still unpainted. And a few more gate crossing signal bridges are waiting to be painted.

Cityline comes to live with lights

The Zity Edge downtown cityline starts to come to live with internal lights in the buildings.

Hundreds of windows are cut out on the facade and glazing are inserted.

54 adresseable WS2812 LED's in the current line, with various colortemperature in the different rooms, including the warning beacons and flashing light on top of the roof. All run by an arduino using the FastLED and MobaLedlib libraries.

The floodlight of the church are installed. More details on the landscape will be installed later.

LED-strip configuration

For the main lighting of the layout, I have installed a total of 7 LED-strips, 3 with Warm White LED's and 4 with adresseable RGB(W) LED's. The extended number of white strips gives a bright light as possible.

All strips are controlled using an Arduino microcontroller, where the 3 Warm White strips are controlled with pulse width modulation(PWM) and a IRF540 MosFet driver card, and the 2 RGB strips are controlled with the FASTLED library available for the Arduino. 2 more Led strips are installed a RGB-strip on the East Mountain backdrop and a 150 pixel RGBW, 17x9 pixels matrix are installed as a skyboard to simulate different colors and pattern, like sunrise, lightning and Aurora Polaris. On this homemade LED-matrix using a standard 5 meter long RGBW-strip(description will follow soon), I use the Adafruit NeoMatrix library. The initial tests look promising. I will come back with images soon. The programming are not finished and need further development.

The goal is to create animations that can simulate day, sunrise/sunfall and night. And some lights effecs, like ligthing strokes with sound and other visual effects. All controlled by a fastclock and swithes connected to the Arduino. Since I plan to run JMRI on a RaspBerry Pi, I am thinking about to create the userinterface on the RaspBerry Pi, connected to the different Arduinos on the Layout. The Arduino is so cheap to buy, so it will be easier to use several Arduinos for different tasks.

The section drawing shows the different LED-strips for main lighting of the layout.

 

The different LED-stripes:(Table is under construction)

Strip # Type NumOfLeds
1 Warm White, 2 wires: 12 volt, wires: +/-  
2 Warm White, 2 wires: 12 volt, wires: +/-  
3 Warm White, 2 wires: 12 volt, wires: +/-  
4 RGB adresseable WS2812B, 5 volt, 144 Leds/meter, 3 wires: +/-/Data (Main Layout Light) 287
5 RGB adresseable WS2812B, 5 volt, 144 Leds/meter, 3 wires: +/-/Data (Main Mountain Backdrop) 235
6 RGB adresseable WS2812B, 5 volt, 144 Leds/meter, 3 wires: +/-/Data (East Mountain Backdrop) 71
7 RGBW adresseable WS2812B?, 5 volt, 30 Leds/meter, 3 wires: +/-/Data (East Skyboard Matrix, 17x9 pixels)) 150

 

Video #2 from Zity Edge Layout

Test of LED-animation

A test with an animation of the LED-strips behind the mountain backdrop. The current colors in the video are just to test to see how it could be. All lights are run by an Arduino microcontroller. I guess I need to use some time to develop the programs for the Arduino. The LED-strip in the video is a 144 RGB leds/meter, adressable WS2812B strip, with a total of 235 LED's.

LED-strips for the layout installed

Some more progress on the building of the new layout. Skyboard and mountain backdrop are installed.

The lights for the layout room and backdrop, are done using several LED-strips. For the overall white daylight, I have used 3 Warm-White LED-strips, for the colored lights, I have installed 2 adressable RGB-strips, one for the overall light, and one behind the mountain backdrop.

The skyboard and mountain backdrop are installed.
