Martin's 3d print tool


Thanks to everyone who attended Sunday's Zoom meeting.

There were five regular Hawick Men's shed attendees and a further two from other areas. Nice to see you all.

Martin Pearson sent me his print file for a solder reel holder that conveniently fits on the PCB holder that Keith Torrington showed us during the meeting.  It's a very useful and robust tool for holding the PCB firmly while assembling your electronic project.

I bought mine years ago and they are much better than the traditional " extra hands" type that use crocodile clips to potentially damage your board.

I had to slightly modify Martin's file by reducing the external diameter from 20 mm to 19 mm so it would fit my particular solder reel. Thanks for sharing Martin.


For those interested in 3D printing, we are hoping to confirm that Alan Geekie will be available to give a presentation on that subject at our next Zoom meeting. Lookout for your invitation by email shortly.

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 mak...

Sunday's West of Scotland Area Group Zoom meeting

 Another very well attended Zoom meeting with 34 participants. Davy showed us the commercially available automatic train stopping unit available at £12.53 from Brimar and compared it with the almost identical PMP 15 kit from the MERG Kitlocker at  only £2.65.  With these kind of savings, MERG membership is worth every penny. Chic Thomson treated us to a very entertaining presentation on simulation software for Electronics. INKSCAPE  is a free open  source drawing package. There are many Arduino Simulators available but Arduino Simulator 1.5.1 is an excellent open source offering.  For those interested in PICs simulators are available within the JAL compiler (Just Another Language) and MPLAB Sim is available within MPLAB but seldom advertised. Electronics Workshop 5.1 is a program no longer being developed but a useful tool for investigating any electrical or electronic circuit. Apparently you can Google it but there are a few insecure sites so be careful. F...

Push button Ezypoints

 A few months ago I produced a batch of Ezypoint kits for our local members to overcome a shortage in the Kitlocker.  At that time the kit was produced on stripboard which some members find problematic. An additional PCB board normally available from MERG was not available either.  Alan Turner ( the PCB designer) had only a few boards available but graciously provided me with the gerber files to allow me to order PCBs directly from China . Having sourced all necessary components, the kits were duly made up. I find this simple kit is really useful for automation projects. A toggle switch provides either a HIGH or LOW on the PIC input pin to determine which of the two servo positions is selected. For a particular application, I wanted to use a push button to toggle the position on alternate presses of the button. This involved a rewrite of some of the code in the PIC. I initially developed the program using an Arduino as a means of testing the logic. When this was successfu...
