Made a wooden base using dense wood upcycled from a scrapped bed.
A hole and a groove were carved to provide enough room for the USB cable to bend. The hole is slightly out of center. Next time I should drill a guide hole first.

The PCBs acquired on a local manufacturer have arrived.
The ground needed to be change to hatch and the layer Tdocu was unfortunately silk screened on the board which required me to scratch the paint over some pads on the RTC chip and resistors.
I have tried out the components on the top layer, and they are ok.
Can not say the same about the RTC library. That's one lesson we have to learn again and again: never trust 3rd party libraries - do a tryout first. At least it was possible to mount the module on the board despite the slant mounting headers.

First complete working version, can show the time, day, month and year.
It can detect when the RTC is not preset or not responding (SDA was disconnected to take the picture)
