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 successfully working, I then wrote an on / off  LED program in JAL (Just Another Language) and compiled and tested for correct operation.

Finally, I looked at Davy Dick's original program and replaced his looping check for change of switch state function and replaced it with the modified version.

As the only thing that needs to change is the data on the PIC, I have produced another set of the Ezypoint PCB kits in both the original and modified form.

Let me know if you would like any of either version. They are both available to members of our Groups at a lower price than currently offered in the Kit Locker.

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...

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...

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...
