I own some old clocks, so a hundred years old grandfather clock and a Polish wall clock manufactured around 1850.
Since the year 2000 I collect vintage RC helicopters from the early 1970s.
When I was a student in the 1980s a restorated a DKW 250 RT motorcycle and then drove it for some years.
The last couple of years I thought about some steampunk projects but none was realized. But when I read on a Raspberry Pi laptop I found that I wanted to have a Raspberry Pi in an old leather briefcase. So that will be my first steampunk project to realize.
