…lets see what they look like.
These days I work with X-Ray systems. I’m just finishing up commissioning and testing of the latest one, so I’m using it to image various things.
This is a compact fluorescent lamp. At full size you can see the coils of tungsten wire in the electrodes in the glass spiral, you can also see some tiny droplets of condensed mercury at the end of the spiral. It;s this mercury that’s essential for the operation of the lamp, but is also what makes them (slightly) hazardous if the glass breaks.
Long time no post again. Spent much of recent time getting on with work and neglecting websites and fun projects.
A long weekend away has me back in the Netherlands; Rotterdam and Leiden to be exact.
There are real contrasts between the two cities, Rotterdam is very new; hardly any building in the center is more than a couple of decades old.
Leiden it’s a fine old university town, fantastic museums, beer and ice cream. The treasures of the university archive exhibit at the museum had several books over one thousand years old. To see a book that old is a bit of a shock, you’re used to stone tablets and similar off great age, not books.
