+ | ====== October 2022 ====== | ||
+ | We were given two presentations in the morning by Andy Cumming and one by David Roberts in the afternoon in out Show and Tell session. | ||
+ | |||
+ | ===== My Layout ===== | ||
+ | Andy give us a presentation of the development of his model railway. | ||
+ | |||
+ | ===== My solutions | ||
+ | Andy's second talk focused on the solutions he developed whilst overcoming some of the problems with his layout. | ||
+ | |||
+ | ===== MERG Layout Control | ||
+ | |||
+ | David gave a short presentation on CBUS, EzyBus and PTP-Lite. | ||
+ | |||
+ | Once again we thank Andy & David for the work they have put in for the benefit of the Area Group | ||

+ | ====== July 2022 ====== | ||
+ | |||
+ | We were given two presentaions at our July meeting. | ||
+ | |||
+ | ===== MERG CANCAB Options ===== | ||
+ | We were delighted to welcome the Warwick and North Oxford Area Group Leader, Simon West, who offered to talk on the MERG CAB options and particularly what will be the new CANCAB2 kit as well as his own slightly larger version. | ||
+ | |||
+ | ===== An Introduction to Electrical Measuring and Testing. ===== | ||
+ | Also,in the morning David Roberts presented An Introduction to Electrical Measuring and Testing. This talk provided an introduction to electrical and electronic test equipment as applicable to model railway electronics. The equipment discussed ranged from the simple multi-meter to the more specialist devices such as the logic probe and the oscilloscope. The presentation also covered how a Digital Multi Meter (DMM) is used to make various measurements. | ||
+ | |||
+ | In the afternoon David kindly offered to demonstrate some of the equipment mentioned in his presentation. Simon discussed with members various CANCAB options mentioned in his talk. | ||
+ | |||
+ | And finally we were delighted to welcome back Peter Wilson and the superb cake! Thank you Aileen. | ||
+ | |||
+ | |||
+ | ====== April 2022 ====== | ||
+ | |||
+ | ===== Train on Tack indicators (TOTIs) ===== | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Andy Cumming talked | ||
+ | |||
+ | |||
+ | ===== Semaphore experience: | ||
+ | |||
+ | Tony Chamberlain is well versed in semaphore signalling having been invited into a signal box at an early age (the bug never left him). He has recently stepped down from his position as a signalman, on the Severn Valley Railway. Tony's presentation commenced by explaining how railway signalling evolved. We were shown examples of various types of signals. | ||
+ | |||
+ | ===== Demonstrations ===== | ||
+ | |||
+ | David Roberts gave the group a demonstration of three modules he has recently built: | ||
+ | |||
+ | **A DCC Loco identifier**. Originally developed by MERG member Duncan Greenwood. The DCC loco identifier provides functionality that displays a locos identity at a button push. While the decoder identifier may be built using an Arduino Uno and a motor shield this unit uses one of Duncan’s PCBs. The output is displayed on a 4-row 20 character Liquid Crystal Display (LCD) via an I2C interface. | ||
+ | |||
+ | **DCC++ EX** This is a complete wireless DCC command station built using an Arduino Mega 2560 module linked to a motor driver shield and a wifi module. This enables you to use either Wi-Fi throttle (iPhone) or Engine driver (android) to operate your layout https:// | ||
+ | |||
+ | |||
+ | **NB1 booster** | ||
+ | Based on the MERG Kit. David built his version that also incorporates a RailCom cut out. | ||
+ | |||
+ | **Design Spark.** | ||
+ | Andy Cumming followed on his talk from the morning by demonstrating in more detail how to use the software. | ||
+ | |||
+ | **
4-servo automated gate crossing. ** | ||
+ | Colin Mitchell demonstrated his model of an automatic gate crossing. | ||
+ | |||
+ | ==== CANPAN LED & Switch patch boards ==== | ||
+ | {{: | ||
+ | Andy Cumming mentioned at our last meeting that he had some CANPAN LED & Switch patch boards on order from the manufacturer. Andy tells me these have now arrived. | ||

+ | |||
+ | == So what is Arduino == | ||
+ | |||
+ | David Roberts gave a presentation to introduce the Arduino in terms of the hardware most commonly used by the Railway Modeller and the Integrated Development Environment (IDE). A look at Shields and other peripherals is included along with a very brief review of the standard interfaces. | ||
+ | </ | ||
+ | |||

+ | ==== October 2019 ==== | ||
+ | |||
+ | John Gowers gave a presentation about the mechanics of a steam engine. How to capture real sounds and apply them to your model railway | ||
+ | |||
+ | He also showed us how to insert sound chips into a loco. This was followed by how you configure the captured sounds to the locos movements and actions. | ||
+ | |||
+ | Here are some of the photos from the day. | ||

+ | === July 2019 === | ||
+ | == Electrostatic Discharge: What it is and Why it is Important == | ||
+ | |||
+ | David Roberts gave a talk on what Electrostatic Discharge is, how it is caused and the damage that it can cause to modern electronic devices and systems. Simple and affordable measures to mitigate the problems were also described. | ||
+ | |||
+ | == The Theory and Practice of a Simple MERG Kit == | ||
+ | |||
+ | Some of us assemble kits without knowing very little about the types of components used and why they are important. David’s presentation considers a simple MERG kit – the CANACT – looking at the components used and explain why they are chosen and how it all comes together to work. | ||
+ | |||

+ | |||
+ | What is Arduino and what can it do for railway modellers | ||
+ | |||
+ | David Thomas presented ‘A CBUS Sound Player’ in which he explained how the project has been inspired by Davy Dick’s sound player (See March 2017 journal and the subsequent threads on the Forum). | ||
+ | |||
+ | Tony Jackson gave the second talk entitled ‘A Magnetic Identity’ in which he introduced the use of magnets to obtain the identity of a loco or vehicle (rather than only detecting its presence) to facilitate effective decisions regarding automating aspects of layout operation. | ||

+ | === October 2018 === | ||
+ | |||
+ | === Wiring and Power supplies for the Railway Modeller === | ||
+ | |||
+ | David Roberts gave two talks in the morning. | ||
+ | |||
+ | The first one, focused on **wiring for the railway modeller** and included | ||
+ | |||
+ | • Theoretical aspects of electrical wiring | ||
+ | • Design & Implementation of electrical wiring | ||
+ | • Examples of wires, tools and terminations | ||
+ | |||
+ | His second talk was **Power Supplies** and explored: | ||
+ | |||
+ | • History | ||
+ | • Direct Current (DC) Supplies | ||
+ | • Linear Mode Supplies | ||
+ | • Switch - mode Supplies | ||
+ | • Sources of Power Supplies | ||
+ | • Commercial Devices | ||
