Carriage Lighting

Another great session at the West of Scotland Group yesterday.

Keith Shovelin treated us to an excellent presentation and demonstration on carriage lighting for both DC and DCC layouts,

Featuring Davy Dick's original Pocket Money Kit PMP 19 created back in 2015, Keith showed how this strip-board circuit could be installed in a 00 gauge coach with reasonable modelling skills. He did give the warning to try this on some old coaches first as disassembling detailed modern coaches does present some risks to the unwary.

For those using DCC an additional diode bridge circuit can be installed so that power can be taken from the track rather than the 3 volt button cell.

To make it easier to place the circuit within the carriage, a surface mount version was designed using a board designed by Fraser Smith. This might also be suitable for undermounting and even on N gauge stock.

This is unlikely to be available as a kit because of the small volumes required, but I'm sure if enough people are interested we could at least arrange for the boards to be made. Looking at the size and with a minimum order of 10 panelised PCB's (12 circuits per panel) each mini PCB would cost about 20 pence.

If you are interested drop me a line on the comment form stating how many you might need and whether you want the button cell or DCC version and I will try and provide a more accurate costing.

Removing coaches to access the on / off switch could be problematic and latching reed switches were discussed as a potential solution.

A stay alive version using a capacitor was demonstrated very effectively on a piece of dirty track.

Even when the carriage was taken off the track completely the lights stayed on for a couple of seconds.

With commercial versions available at around £20 the MERG kit provides exceptional value for money.

Thanks to Keith Shovelin for a fabulous presentation.

3D Printing Presentation

Sunday's Zoom meeting had our largest audience so far with 19 members attending from various parts of the country. Alan Geekie gave us an excellent and well received presentation on 3D printing that included FDM (Fused Deposition Modeling) and SLA (Stereolithography apparatus) types He first showed how we can source "things to print" using sites like Thingiverse. His own filament printer was the Prusa i3 Mk 3S which is available either as a kit (£699) or pre-assembled (£899) and features a self leveling bed. It also benefited from an additional multi material upgrade kit and he demonstrated the start up sequence of leveling, homing, clearing remaining filament from the hot end and then beginning the print. The process of slicing where a 3d object drawing file (.stl) is broken up into the x,y,z drawing coordinates for each individual layer was also explained. Alan then moved on to resin printers using another Prusa model, the SL1 and its associated curing and washing mach

Train sequence / timetable using Arduino

Following discussions in a MERG Zoom meeting about potential projects for the Cumbria virtual area group I have started this blog to share my ideas for building a train sequence / timetable system based on an Arduino UNO. The trigger for this project was Andy Robb's article in the MERG journal (June 2020 edition). In it Andy describes using an UNO with a OLED display to produce an electronic station display board. Having tried out Andy's version I started thinking about expanding the idea and have come up the following list of possibilities: 1. Replace my card index train sequence with an electronic version. 2. Have the train sequence synchronised with the on platform displays. 3. Display an analogue clock on the station display and have it display the train times. 4. Store the position reached in the sequence so that it starts where it left off on power up. To make the project of greater potential interest to other modellers the following

Arduino Book Recommendation

Welcome to the site which has been set up for all members of the Scottish Borders Group of MERG. As you know, I have been working on various Arduino projects recently including the station and cafe displays. There are many resources available online when you come across a problem but a good reference book which explains how things work is essential. I have tried a few and found the following book the best so far. It is well written and laid out logically for the beginner to be able to develop new skills. The structure of the Chapters makes it easy to find the relevant section. By clicking on the link below you will be able to look inside and see for yourself. https://amzn.to /38HfrWW If you decide to purchase through this link you should be aware that I will receive a small commission on any sales generated which will help to finance further projects Andy R
