Deze (onafhankelijke) webpagina is een doorstart van www.amateurtele.com. Medio 2022 is de website na vele jaren uitgeschakeld, maar door nieuwe inspiratie is de website weer in de lucht. Weliswaar moet de code nog grondig worden aangepast en verbeterd, dus deze website is nog sterk in ontwikkeling. Dus nog even geduld voordat alles optimaal functioneert. ;-)

Latest news/blog post: 09/2024
image Recently I bought a pedestal of an Airbus A340 airplane. I had already (most of the) overhead panel and the pedestal is a nice addition to this. The first steps are documented; inspection and cleaning. More will follow eventually...

There are so many articles here, that it's sometimes hard to see the relation and structure between everything. Therefore I had the idea to create a tree structure so get everything more clear. Last week I managed to create a 'recursive' loop to obtain the tree structure. This is still in engineering phase, but the hardest part is done! So I expect soon a much better navigation structure.
