Talk Morgan Forums Community The Malvern Arms Lockdown project

The functioning "prototype".

Still needs wood facia, dial bezels, glass and proper Speedo needles - the ones fitted are carved out of a piece of wooden cloths peg. I'm sure that committee would approve of the use of some wood

The lockdown has slowed down access to components and I have to wait until people get back to work in order to try and source the instrument spare parts to complete the clock.

The program that drives the microcontroller is pretty much complete. It has a small Real Time Clock with a button cell battery to keep the time so that the clock hands automatically reset to the correct time at power up. It also automatically compensates for daylight savings time and advances and retards the hour on the appropriate dates and times.

The next trick is to try to port it to a smaller microcontroller and try to power it with a rechargeable lithium battery. I suspect the current draw will be too much to effectively power it with a small battery pack.

I copied the Richbrook knob used on the Morgan Mazda gearbox. It has a metal insert which is threaded to take the original ring that covers the retaining grubscrews. I used the insert from the Richbrook for the gear pattern.
