DIY Oxygen Analyzer

For a long time i wanted an oxygen analyzer in order to double check my Nitrox mixes.

With a couple of parts an LCD display and a Teledyne sensor it is finally alive 🙂

One year using gmail

Today i celebrate one year using the gmail.

2GB was more than enough. I use it for all my mailling lists and after one year i still use only 85MB of my space. It contains about 6000 conversations and counting

It is a relief for my normal mail account 🙂
