welkom
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. ;-)

English 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. The new navigation is implemented an hopefully it's easier to find the desires information. :-D

image Two years ago I made a simple test video of the Sfena H301 BAM artificial horizon. In two years the Youtube video had around 20k of views. Last weekend my mailbox 'exploded' with Youtube subscriptions and video comment notifications. And within a couple of days the amount of views rose to 200.000+! This inspired me to make some photo's ans finalise the planned article.

Since I renewed the navigation of this website I discovered a number of unfinished articles. So I took the time to finish some articles like this article of an airband radio receiver kit.
