Welcome
Welcome on "Eelke Visser.nl". This is where I show some stuff I am working on.

If you are interested in the communication protocol to connect a microprocessor to an Opel display than visit the Opel electronics section. I used the display to make a tachometer for my Astra. It shows the amount of revolution the engine makes per minute (RPM). I have also received some very nice feedback about other Opel display projects, which are also worth a look! 

No Opel display? No problem, take a look at the Any tacho page!

There is also some old stuff about a Digital Compass. These pages are in Dutch. It is a nice project. It works fine. But it never made it to a boat...

Send e-mail to if you want to contact me personally. 

Thanks for your visit!

Best regards,

Eelke Visser.
