Model Railway Dashboard Project

I’ve updated the website with a new “dashboard” page.
The wiring is going to be the fun part.
For these 4 connections I’m considering using the following method:
The question here is what kind of diodes (U1) do I need to convert the 16VAC to DC current so that D1 (in our case ammeter) lights up?

The Model Railway is divided into distinct roles:
  1. Shunting (Port and Depot)
  2. Non-stop Train compositions (eg.. TEE - Trans European Express)
  3. Commuter Trains and
  4. Goods delivery
This makes the whole setup more interactive.

I also use iPhone applications (see http://www.siweckp.com/touchcab.htm) so that everything can be steered using TCP/IP - assuming that all the hardware can be controlled via my digital Control Center (in this case Märklin CS1 "Reloaded"/ESU ECoS System).
To avoid collisions I also use a GPS Control System called Gamesontrack in conjunction with iTrain Computer Software (for more details: http://www.gamesontrack.dfrobot.uk)
The attached Images show you where we are today - shadow rails i.e., all that is invisible to all viewers/visitors.
Next comes all the cabling, which include  the dashboard  electronics supplied by DFRobot.

In the very near future (once the Christmas period is over) I'll look closely at your servo mechanisms and RC systems to create Scenes such as:
  1. automatic door opening for both Train carriages and depots
  2. electronic platform Destination boards
A tall order but there are definitely forum members out there who have good ideas.

Here from you soon

What are you planning on doing to make it more interactive? Or you just want to have the train setup controllable? What about a movable object remote control around? It's quite nice to have a functional miniature with an alternative controllable device that can "break" the rules of the simulation, say, alter traffic by triggering sensors, or navigate the town from a different point of view than the trains.

The Dashboard

The Why

It came to me as a sort of “there is something missing” in this construction.
With all the possibilies in terms of lighting, motors and general  landscaping available on the market, it became clear that I had to build a dashboard from which all components can be controlled. The easy part is the  use of the Central Station for the digital control of the locomotive compositions and turn-outs. The tricky part is the rest, what with LEDs using different  voltages an currents.

The What

Take a look at these figures:
The construction (when complete) should include:
• over 270 light sockets of which:
ca. 150 for housing and factories
ca. 100 for for street lamps, floodlights and Motors
ca. 20 for railway platforms
ca. 100 LEDs for vehicles (cars, buses, lorries etc.)

These facts just show that the hobby is very detailed, and requires a “dashboard” for:
? careful monitoring of ampages and voltages
? calculating the number and type of transformers for current and future considerations
? distribution of the following power circuits:
• Main - for my digital control centre 18-24V AC max. 4A*
• 16V AC for lights 3.15 A*
• 12V DC for certain accessories 0.6 A*
• 5V DC for speciality accessories 0.6 A*

b]The How[/b]

With the unexpected assistance of the local primary school, I managed to salvage an old desk and created the following design (See http://siweckp.com/dashboard.htm)[/font].

The conversion to a dashboard was made by George Zimmermann (nothing to do with Florida), who has a fantastic, rustical workshop, fitted with all the  tools that you could imagine. I was the perfect assistant - don’t touch anything; sit down and just do as I’m told.

The Gallery: Pictures speak louder than words, so the following images show the results of our efforts. The wood, metal legs and consumables were supplied by  Jumbo hardware store.
Electronic components were purchased from DFRobot
The Transformer(s) There are mostly standard, supplied transformers (image bottom left) for digital control centers.
To meet the criteria for all the prerequisites mentioned  above, the following sprang into mind and I immeadiately acquired the Faller product (image bottom right)

More ideas such as lighting, automatic doors for locomotive Depots and housing, are in the Pipeline.

Best regards

2013-11-27 14:18:36 Single phase bridge type rectifier circuit is OK.
And it is a good idea to add a big capacitance in parallel. It will eliminate some harmonic wave.
For the safety factor, it is better to  choose about 25V4A one.
It is better choose high value diodes.
