Lead seals

This weekend I have setup a site to identify the different types of lead seals that are found in the Dutch soil, mostly with a metal detector. There are so many different types, and the text on the seal is often hard to read. So I thought that a site dedicated to those lead seals might help to identify the ones you have found.

Water and fire

The last week was a strange one. On wednesday I woke up due to the fire alarm and on saturday due to rain leaking through the roof, and dropping exactly on my pillow. Fortunately, the fire alarm in my Helsinki hotel was false, but it was a lot of noise with the alarm bells ringing at full strength and the TV sets turned on at maximum volume. And the rain leaking through the roof was because of a small negligence of the construction team working on the extension of the top floor of my house. Anyhow, waking up like this two times in a week doesn't make you feel like you slept very well...

The last preparations for Helsinki: collect all necessary paperwork, store the digital stuff on the laptop, and don't forget the chargers for all the mobile devices. Otherwise, the cell-driving effort will come to an early stop. And it would be nice to extend the GSM/GPRS cell database with some Finnish cells!
