Bristol group meeting Thur 11 July

I shall be bringing my Pinebook Pro and demonstrating an application that is so arcane I cannot explain it. The mechanical locking in a signal box is a superb mechanical computer and capturing it as it moves took rather a lot of time to get right!

For a sneak preview, see here

Yes, I’ve already been looking at this application in admiration, although I know nothing about railways and their related mechanics.

Interesting – things like mechanical calculators.

Early radio stuff was very mechanical.

[Edit]

They are just changing over to lights down here from mechanical signals.

I suppose the big advantage is a big remote signal box can control everything!

I’ll also be brining a handout on editing vector graphic files
