Power Supplies for Electronic Modules

At the 23rd October Meeting of the Cumbria Area Group, we were joined again by David Roberts to present the second of his talks on Power Supplies, this time covering Voltage Regulators for Electronics Modules. He covered linear regulators including the 78xx and 79xx series.

The important subject of regulator efficiency was discussed with the requirement of heatsinks to dissipate the unused energy.

How Power Supplies are designed and used was illustrated using some of the readily available MERG Kits including the 5 Volt Adaptor Module (Kit 60), 12 V from an ac supply PMP 6 ( Kit 806), the Universal PSU (Kit 920) and finally CANACC5 (Kit 85).

Then the much more efficient and more expensive switching regulators were covered towards the end of the talk, followed by a general question and answer session.

Andy Woolass has managed to record both of David's talks and I am delighted to let you know that these are now available on Channel 36 in the MERG TV section of the website.

If you are wondering how you burn your hands when you touch a regulator, have a look and all will be explained.

Our thanks again to David for a most informative talk

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...

Safety in the workshop

An excellent presentation by Dr. Craig Lennox on workshop safety at today's West of Scotland area group meeting. An amusing but nevertheless serious video was followed by a detailed talk on safety and first aid. I am hoping this talk will be made available on the WOSAG website in due course. The take home message is to ensure your workspace is well ventilated, tidy with no trailing cables. Plan what you are going to do using appropriate tools, avoid distractions and don't rush A clear head is essential. Use PPE where necessary for example ear protection, safety glasses and laser glasses. The risks of burns, cuts, electrical shock and inhalation of dust and fumes were all covered in some detail. Automatic External Defibrillator (AED) are now installed in most supermarkets. A short video was shown illustrating just how easy they are to be used. Excellent talk. Keep safe everyone.

Mimic Points in Visual Basic

For this project, I wanted to create a moving graphic to mimic a set of points moving from one position to the other. This Blog shows all that is needed. The first Picture shows the 6 lines needed. This Picture shows the Line Properties. The tracks are shown with 5 lines, though only the middle ones in red are involved. The other line shown below the others is the one that actually "moves". It is shown below the other lines for clarity only. At the start of the Program running, it is positioned over the lower red line. In VB, each Line has properties and these are shown above. To get a line to appear to move, all that needs to be done is to gradually change the X2 and Y2 co-ordinates of the line. This is the code for the program. The first 6 lines create a pause Function in the program, by using the Computers internal C...
