Hi,
I try to itroduce myself (sorry for bad english):
I am retired Electronics Engineer. I started as entry class Engineer (Consumer Electronics) it ended finally as Service, IT and Logistics General Manager in that company.

If one of my friends has broken electronic device, they ask me to fix it.

Beside of that I play with Smart Home (Home Assistant) and from time to time I help myself and others with installing Solar Systems (photovoltaic).

From time to time I need to fix my car. If washing machine fails, my wife will call me.
