I mentioned in the last post that I will be trying out the display modules. I found it easier to break away from the original TfaC Git Hub project and create a new one dedicated to the research and development for the display module. The new one is simply ClockDisplayModule. The first consideration I needed … Continue reading Branching out
Back to the Drawing Board
Well, not exactly back to the drawing board for everything... What has developed since doing the actual schematic is that the display module was treated as a black box. Now it is time to open this up and understand how this is to work. The beauty of this approach is that not knowing anything about … Continue reading Back to the Drawing Board
Wired for Action – almost
In the last post, I presented the initial ideas for powering the project. Now it is time to move on and start looking into the individual modules. I was impressed as to how quickly this part progressed since I had done the up-front thinking of the pin and port allocation. So much so, that before … Continue reading Wired for Action – almost
Module One – Power On!
In the last post, the basic device was layed out in terms of requirements, block diagram and a state machine. It is clearly not 100% complete but I don't believe that the whole project should be blocked, trying to model absolutely everything. As the project develops and matures, issues will be encoutered and design decisions … Continue reading Module One – Power On!

I have mentioned about the re-working of an old alarm clock. In this post, I will be kicking the project off and introducing my efforts to model the requirements and project organisation in SysML. I will be using Systems Architect from Sparx Systems. Project Organisation The project organisation shows the directory structure of the project … Continue reading Modelling First
Time for a Change

I received this in 1980 and it worked reliably well until late 2012 when if finally stopped displaying the time. It is amazing that it lasted as long as it did. The tone was not a … Continue reading Time for a Change
