In this manual the 3-bladed VIRYA-1.04, electricity generating windmill, is described. The generator of this windmill is made of a Shimano Nexus hub dynamo type DH-2R40 or another type with similar flange dimensions. It is expected that, together with the detailed drawings, the windmill can be manufactured in a simple workshop.

Dear friends
Since yesterday I have my own website: http://www.kdwindturbines.nl . I have designed this website myself using the nice book ”Een website maken voor uw eigen bedrijf” (May 2014, in Dutch). The website gives information in English about my VIRYA-windmills and public KD-reports. From 1 February 2015, this information is no longer available on my page on the website of Bidnetwork because Bidnetwork is cancelled at that time and replaced by Bidx.
