- | **Jan 31st** Inaugural Meeting\\ | + | In Normal times, |
- | Twenty eight MERG members met in the Leamington and Warwick MRS clubroom | + | |
- | **Paul King - MERG President, | + | |
- | **Pete Brownlow**, in his usual relaxed manner, briefed the group about CBUS and future developments.\\ | + | |
- | **Chris Boxall**, a Severn Valley signalman, led a very interesting and interactive session which only skimmed | + | |
- | The day closed with **Mike Plowman** describing the CBUS implementation proposed for the new LWMRS n gauge layout – Kineton.\\ | + | |
- | **April 23rd**\\ | + | Meetings generally comprise:\\ |
- | Thirty five members and guests from the host club attended the meeting held at the L&WMRS Club Rooms\\ | + | * A presentation on a subject previously requested |
- | The morning was dedicated to the **MERG DCC solution** with a presentation | + | * Open workshops / discussions. |
- | **Tony Chamberlain**, | + | * Assistance |
- | For the first time, the afternoon was set aside for a soldering | + | </ |
- | **July 9th**\\ | ||
- | Another strong attendance were treated to a presentation by **Don Upton**, assisted by **Bob Mercer**, who presented **“CBUS Live”** adding CBUS modules to a small layout to drive various accessories. The features of each module were described before being physically attached to the baseboard. Once all the modules were installed, Don proceeded to explain the facilities of **FCU/ | ||

- | **Sept 24th**\\ | + | ====GOVERNMENT RESTRICTIONS ON GATHERINGS AND TRAVEL==== |
- | The group met again at the **Leamington and Warwick MRS** club rooms.\\ | + | |
- | The members were greeted with the now customary **LWMRS bacon roll** breakfast.\\ | + | |
- | Proceedings started with **Judi Rastall** who had made the long journey to tell the members about the operation of the **Kit Locker**, a presentation that was well received and generated a large number of questions.\\ | + | |
- | **Mike Plowman** followed with a presentation on the **Layout Control Dilemma** showing how the selection of CBUS did not require the adoption of DCC.\\ | + | |
- | Finally, **Bob Mercer** gave the first of series of presentations about the use of JMRI. The live demonstration had a very positive effect on a number of members and we are looking forward to the next part of Bob's series.\\ | + | |
- | After afternoon tea and cakes, the informal part of the meeting allowed members to exchange ideas and get questions answered. | + | |
- | **November 12th**\\ | + | <WRAP center round alert 85%> |
- | Over 30 members congregated at the **Leamington and Warwick MRS** Club Rooms for this fifth meeting of 2016. | + | **Since April 2020, the group have been holding fortnightly Virtual |
- | As this was the end of our first calendar year for the WNO area group, each member reintroduced themselves to the group, restating their interests, the progress they had made in the past year and what items they would like to see included in the agenda for the coming year.\\ | + | |
- | Members were also asked to contribute ideas for the **Area Group's celebration of MERG's 50 years** in 2017.\\ | + | |
- | **John Russell** showed how to interpret circuit diagrams and work out what voltages to expect at various points in a circuit which was really useful when testing and fault finding modules.\\ | + | |
- | **Chris Boxall** gave a very comprehensive presentation on the block signalling process on the Severn Valley Railway. This included a demonstration with three members "bell coding" | + | |
- | Due to time constraints, | + | |
- | For next year, it is clear that the presentation part of the meeting will need to be carefully planned so that enough time is allocated to the growing need for more **practical sessions**. | + | |
- | ==== 2017 Meetings ==== | + | We are expecting to start physical |
- | <color # | + | </ |
- | Over thirty MERG members met in the **Leamington and Warwick MRS** clubroom for the first 2017 meeting of the Warwickshire / North Oxfordshire MERG Area Group.\\ | + | |
- | They were welcomed with the customary, signature bacon rolls with tea or coffee prepared by the Leamington and Warwick MRS Exhibition Manager and MERG member Mike Collins. This has become quite a feature of our meetings | + | |
- | **Mike Plowman** introduced the meeting and thanked all the members who had contributed to the success of the group in its first year.\\ He continued by outlining the next meeting which will be held on the first Saturday | + | |
- | Following feedback from members, Mike proposed that the format for all meetings | + | |
- | **David Thomas** opened with an **RFID** presentation, | + | |
- | He went on to demonstrate, | + | |
- | Meeting in the Leamington and Warwick Railway Club has the added advantage for the MERG members of being able to access the enormous resources of the club library.\\ | + | |
- | Our resident enthusiast, **Bob Mercer** continued his **“Introduction to JMRI”** with part 2 of his talk not only talking about the function and facilities but demonstrating, | + | |
- | During lunch, the room was reconfigured to define focus areas for the afternoon. David and Bob were able to answer more detailed question about their morning presentations Whilst **Brian Flanery and Simon West** ran a clinic helping members to fault find their CBUS kits.\\ | ||
- | The new meeting format proved to be to the members liking and we will continue in this manner along with our informality, | ||
- | <color # | ||
- | The March Area Group meeting was held on the first day of the Leamington and Warwick Exhibition on **March 4th 2017**. | ||
- | Again over thirty members attended the meeting and were treated to two informative presentations.\\ | ||
- | **Martin Perry**, MERG Technical Support Manager and Vice Chairman gave an excellent presentation on the subject of the **The MERG Kit from Design to Availability**. This stimulated many questions both from the members and Martin. It quickly became apparent that few members understood Martin’s role as the Technical Support Manager and how he could assist in the solution of issues with kit build and test.\\ | ||
- | A 3D printing machine was quietly producing parts at the side of the meeting room whilst **Howard Watkins** presented an **Introduction to 3D Printing**. Howard explained how parts could be designed using free software and using even more free software, the part could be checked and an STL file produced to drive the printer. | ||
- | He explained several techniques that were required to produce large parts and how the features of the various models of printers alleviated some of the problems.\\ | ||
- | Discussions continued over a buffet lunch and it was clear that many members had been impressed and inspired by both the presentations.\\ | + | ==== Area Group Workshops ==== |
- | **Meet the Committee, | + | <WRAP center round info 95%> |
- | At the Warley show last year, several Committee members agreed to participate | + | //Workshops are always held in the afternoon |
- | Members | + | * Members bringing their own kits to assemble |
- | After a slow start, there was a wide ranging discussion of number of technical, documentation and organisational | + | |
- | **MERG@50, | + | * Members interconnecting working kits to learn how kits can work together to improve |
- | The final act of the WNO Area Group Meeting was the cutting of the Anniversary cake. It seemed such a shame to cut the MERG Logo’d cake but Bob Vetterlein, accompanied by the other Committee members, wielded the cake slice with aplomb and the cake was enjoyed by all.\\ | + | // |
- | {{ : | + | * Introduction to Arduino |

+ | * Configuring CBUS using FCU. | ||
- | **<color # | + | </WRAP> |
- | Several new members joined the thirty members at the **Leamington and Warwick MRS** clubroom for the third 2017 meeting of the Warwickshire / North Oxfordshire MERG Area Group.\\ | + | |
- | They were welcomed with the customary, signature bacon rolls with tea or coffee prepared by the Leamington and Warwick MRS and MERG member **Mark Reader**. This has proved to be a useful time for members to chat before the start of the meeting and members arrive early to chat. | + | |
- | **Mike Plowman** kicked off the proceedings suggesting a further change to the proceedings. | ||
- | **Simon West** gave a very interesting presentation on the subject of Printed Circuit Board (PCB) design and manufacture showing examples that he had created using various techniques from hand layup and photo-etching to design and manufacture using the latest CAD applications. His presentation encouraged many questions and many members came away with a clearer understanding of the design and manufacturing process. | + | ====Joining |
- | **David K Roberts** explained the principles of wiring the layout including wire size selection, routing and termination. He explained current carrying capacity and voltage drop considerations. This subject is quite often an afterthought but David' | ||
- | There followed two presentations by the Chairmen of model railway clubs within the WNO area.\\ | + | <WRAP center round important 95%> |
- | **Tony Moss** represented Coventry MRC http://www.coventrymodelrailwayclub.org.uk/ | + | To attend a Warwickshire, |

+ | <WRAP button> | ||
- | In addition to the workshops and demonstrations in the afternoon, two subjects that will be presented at the next meeting were previewed. \\ | ||
- | ** Tony Chamberlain** previewed the sound generator which has generated an enormous amount of interest since it was written up by Davy Dick and featured in the Journal.\\ | ||
- | ** Bob Mercer** previewed his work with Raspbery Pi and its application to model railways.\\ | ||
- | It is hoped that these previews will become a feature of future meetings. | ||
- | <color # | + | Once you have signed up, make sure you join the Warwickshire, |
- | Almost 30 members met at the LWMRS Clubrooms for the July meeting.\\ | ||
- | After the introduction and plea for new presenters for the next meetings by Mike Plowman, **Jeremy Mole** explained how he installed DCC sound in a small n-gauge shunter. He showed, in detail, the modifications he made to the inside of the body and the chassis in order to accommodate the decoder and speaker. Jeremy then demonstrated the completed loco on a rolling road. The presentation is filed in the area group database. | + | <WRAP column 50%>< |
- | **Bob Mercer** continued his series of JMRI presentations, | + | </ |
- | **Tony Chamberlain** showed the investigations he had conducted with regard to RFID sensors, their shape, effective detectable height and sensitivity with regard to loco speed. This session proved to be highly interactive and showed how this subject is becoming of more interest in the group with several members wants to share the data and participate in the investigations. | + | < |

- | The workshops and informal discussions continue to be a popular part of the meetings with groups of members discussing configurations, | ||
- | <color # | ||
- | Thirty members again met at the LWMRS Clubrooms for the September meeting.\\ | ||
- | After the introduction by **Mike Plowman**, he thanked the members who have come forward to present and also those who are willing to participate in the "show and tell" sessions. | ||
- | **David Thomas** explained explained the basic capabilities of the Arduino and showed how it could be used to accomplish several railway projects. This stimulated much discussion amongst the members and David used the demonstrators that he had prepared in the afternoon workshops where more discussion continued. | ||
- | **David Radcliffe** gave the first of the show and tell presentations telling how he had participated in a “real railway” project for a television company building a railway from coast to coast in the north of England. The many challenges encountered along the route were described along with many entertaining tales. We have to wait for the TV programme to find out whether the team were successful – Dave is sworn to secrecy. | ||

- | **<color # | + | </WRAP> |
- | On November 11th 2017, seven new members were included in the thirty two members who attended. | ||
- | **David K Roberts** gave a very informative presentation about power supplies. He explained, and showed, the various types available and the principles of regulation. There was much interaction with the audience especially concerning component selection. | ||
- | As the meeting was held on **Armistice Day**, the group marked the moment with a one minute’s silence at the eleventh hour. | ||
- | **David Thomas** showed how he had investigated the provision of “stay alive” to various DCC decoders. This is a particularly challenging in smaller scales due to the size of the capacitors required to overcome small “dead areas” on the track. This is becoming even more important with the increasing use of sound in locos. David showed the various experiments that he had conducted to increase his knowledge of this important area of application. There was much discussion around the demonstrator during the afternoon. | ||
- | The workshops and informal discussions, | ||
- | **John Gower’s** soldering workshops always attract an enthusiastic group learning or improving their skills under John’s guidance. One new member commented that he was now confident to start buying kits to build. | ||
- | **Bob Mercer** showed the advances he has made with an Arduino sensing the presence of cassettes in the fiddle yards of the LWMRS Kineton layout using LDR’s. He then communicates the results via CBUS to the fiddle yard at the other end of the layout. | + | </ |
+ | ==== Exhibitions ==== | ||
- | I also have offers of presentations from Kelly Harding (PiSprog) and Roger Edwards (ATBus) which will be included in the programme for next year. | ||
- | ==== 2018 Meetings ==== | + | <WRAP center round info 95%> |
+ | The WNO Area Group actively support the | ||
+ | **Leamington & Warwick Model Railway Society Show** which is normally scheduled for Saturday and Sunday of the first weekend in March.\\ | ||
+ | The LWMRS Board have not yet made the decision to host an exhibition in 2022. Even if social distancing rules are relaxed there is no guarantee that visitor numbers will have recovered to pre Covid-19 levels to make the Society Exhibition viable. \\ | ||

- | This involved a complete rewire providing for continued analogue D.C. operation but now based on common return wiring which immediately nearly halved the number of wires requiring connectors. DCC operation has been allowed for as an option with the possibility to switch out the analogue controllers and connecting to DCC ‘districts’ instead. | + | |
- | CBUS has also been used to further greatly reduce the number of wires and connectors needing to come back to the main control panel for operation of turnouts and the relays that are used for joining track sections together to form routes for a particular analogue controller. | + | {{: |

- | Emphasis was placed on reliability and how to cope if the electronics fail for some reason. Careful design ensures the normally closed contacts of the relays are used so that the two continuous runs are available via a storage yard road for each, as is the branch line and the goods and loco yards so trains can still run without the electronics working, just no fancy moves across junctions but ensures the public would see trains moving at an exhibition. | ||
- | The 20+ CBUS modules around the layout are all CANMIO boards running various firmware depending on function with the aim to gradually update and standardise these to the universal CANMIO firmware of which there is one already in operation providing more than 8 outputs and a few inputs to be achieved with one CANMIO board. | + | <WRAP button> |

- | To simplify the operation and make the control panel as intuitive as possible JMRI PanelPro software is used to provide route setting capabilities and interlocking logic between the push buttons and indicators (which were also connected to the layout CBUS) on the panel and the turnouts, relays and signals on the layout. | ||
- | The talk was followed with a viewing and demonstration of the layout control system and questions and answers. | ||

- | **David Thomas** showed three projects | ||
- | - DCC Suttle | ||
- | - CBUS Sound System | ||
- | - Multi Cab Controller. | ||

- | The **CBUS Sound System** uses the "sound card" with an Arduino Nano and MPEG3 player on board.The CBUS interface is connected to the outputs of the Nano and set up using FCU Generic mode. Cbus events (for instance from sensors) can then generate sounds. | ||
- | The **Multi Cab Controller** was developed to suit a samll demonstration layout at the David' | ||
- | |||
- | There were two parts to the presentation by **Jeremy Mole**. | ||
- | Jeremy has used an Arduino to provide a means of communicating between the cassette yard operators at either ends of the LWMRS N-gauge exhibition layout Kineton. It uses CBUS as the communication method to transmit predefined messages about the type of train being sent from end to end. Jeremy is working with **Bob Mercer** who is also a member of the Kineton team to automated messaging regarding the presence of a cassette, it's state (empty or full) and an automated stop. | ||
- | |||
- | In the second part of his presentation, | ||
