weekend in Canberra

I drove to Canberra this weekend. It took about 3.5 hours by car. The hotel was a little bit outside of Canberra but more or less cheap and with a good rating.
There are many toll streets in Australia. Although, you can not pay cash always. One way is to register you and your hired car at a special homepage. You can also add cars. Every time you register a hired car you have to enter start and end-time of the hiring.

I visited, among other things, the Deep Space Communication Complex,

I didn't know that the station was one of the two who received the signals from the moon during the first landing in 1969.

the Da Vinci Machines Exhibition

It is unbelievable, in almost every mechanical machine that is used today is a part that was invented by Da Vinci.
The picture shows a saw, which is powered by water.
