Ben’s HobbyCorner

This is my homepage, showing things I am working on for a hobby. To do a quick update, not losing a lot of time, I use Sphinx Python Documentation Generator. I also deleted the 80C535 project on this homepage.
Who am I?
Ben Zijlstra. Network Engineer (mainly Cisco) at a large ICT-company in The Netherlands. My first step in electronics was when my father gave me an Philips EE experimental box. Must have been more than 50 years ago. Check LinkedIn for the companies I have been working for (and the present one).


What’s new and when was the last update of this homepage?

November 25 2014:

  • Cathodic Dis-bonding Tester - webbased

This is a Cathodic Dis-bonding Tester. This device, during a month during test, tests the quality of paint. Two probes. Through the display and three keys the parameters can be filled in, voltage to put on the probes. But it is also web based and can be configured through the Intra/Internet.
