Welcome to Kriwanek's Website!

Here you can find information about our favorite cats with many pictures. In the field of cat protection there are detailed instructions for the electric fence. Completely new is the construction instructions for a cat scratching tree! The blueprints (Google Sketchup) can be found in the download area.

One of our hobbies is the DOG-Game. A play instruction and the training results are available to you.

A wealth of contributions are devoted to the subject of microcontrollers (Arduino, Raspberry Pi and others). Free sketches and tutorials help you with your own projects.


I wish you a lot of fun with surfing!

Your Andreas
