I finally got around to do a video about a method to find our projectile speeds, without using expensive gear like an actual chronograph or a highspeed camera. I tried this out first a couple of years ago with a bow, and its works reasonable fine, probably within a margin of error of +- 5% or so.

#8 - 8500 km Solo-Trip um die Ostsee

After endless hours in my Video cutting program here is a summary of scenes of my trip around the Baltic Sea. This time even with music, and I think it even fits quite well.


New photos in the.. Photo-Section. A while ago I finished a roadtrip were I drove around the whole Baltic Sea and visited the North Cape. From this trip quite a bit more content will soon come to the site. First, a small video about an interestin optical effect I saw while being in Copenhagen.

#7 - Dark is always on the Right

#6 - Simple Shelf with little Effort and no Skill

In the video about the lenses I noticed that such documentations of "How-To"-stuff can become a bit...boring very quickly. For that reason I tried to keep this video a bit more exciting and entertaining by using faster, shorter cuts and more timelapses (and just leaving a whole lot out). I get the advice to add music, but to be honest I have a hard time finding something appropiate. Often I get annoyed by wrong music in videos and would rather prefer no music at all.


With every new video I try something new; music this time. Its actually not so easy to find the right one as it has to be good, fitting and come with the right licence (Creative Commons). Unfortunatly still you can never satisfy everyone with a music choice.

Another thing I tried out was to strap a GoPro to a steering wheel, instead of fixing it to the window or other places of a car. It made a cool effect I think. So with this I went on a drive through the neighborhood in this usually good weather for a german winter and made a nice timelapse video.

#4 - How to make Optical Lenses

The speed in which I produce new videos is hard to believe! Again something new after only 1 month :). This time it is about a topic that follows me for quite a while now: optical systems and the quest to make lenses in an acceptable quality.

In any case, thats what I also learn from such videos, I should definately make shorter ones - in exchange for higher quantity hopefully.


A new video. This time a small review of a crossbow that I got recently (..after a 6-month delivery time..). The Talon Eagle Pro. Coming up next probably more content with this very crossbow.

Also did some bugfixing on the menu: the error that occured on Internet Explorer wasn't actually an error and more a wrongly written CSS-File by me :)

#3 - First Impressions of the Talon Eagle Pro Crossbow

Improved the layout of the site and made it easier to read and started doing the english subsites. Also started with the page for DIY-Projects. So far its only the thumbnails and dead links. To produce the content for that one takes a while. For some reason the display of the menu in Internet Explorer doesnt quite work right. I dont know yet why that is, but I am open for suggestions :).


After the domain provider of my old personal website '' closed down, I bought this new domain '' and made this new website. Design and layout are much simplified and more sleek now and I added a lot of new content, like the videos from my Youtube-Channel, DIY-Projects and other things that interest me. The traditional subpages with artworks, photos etc. also remain of course and got updated.


#2 EN - Homemade Crossbow out of Spring Steel

My second video for my Youtube Channel. This time it is about a DIY-project that occupied me for a while. This homemade crossbow is the first evolutionary step of a project I will pursue a lot further in the future. Things like a aiming system are still missing entirel. Also the gripp and the shoulder rest are only temporary so far. This will get much better in the next steps.


I now have a small Youtube Channel on which I will - unregular so far - add videos about topics that interest me. This will be mainly things like vehicles, DIY stuff and explanatory videos. For the start it is a video with a ride on my motorcycle.
