Steam engine / Dampfmaschine Kosmos Technikus
My second take on the Kosmos Technikus steam engine - and a rather lengthy one at that, so if you're easily bored don't watch it (or watch the last 30 seconds where the engine is actually running). The Kosmos Steam Engine was developped in Germany in the thirties as part of an educational physics workshop kit; I got one of the kits for christmas in the seventies:-)
Unfortunately Kosmos discontinued this particular science kit - probably because it wasn't any longer considered safe for children to "play" with. Let me stress again: The engine shown in the video wasn't constructed by me but is part of a science kit for education which was available in Germany from the thirties to the 1980ies. The kit is no longer available new. However, kits show up on ebay (search for "Kosmos Technikus") and sell for 30 - 90 Euros.
If you want to try to build your own anyway, keep in mind:
Construction of the valve mechanism is tricky and requires some technical expertise and either suitable tools - a metal working lathe for instance - or ingenuity paired with a DREMEL. I prepared a zip-file wit fotos and drawings from the instructions booklet which came with the kit. It can be downloaded from my dropbox; here's the link:

(Let me stress again, that I didn't build the parts for this engine myself. And If you want to build the parts, you NEED to have some expertise in Metal work or know someone who has.)
Because I wanted a very shallow depth of field I positioned the camera at a distance of 6m and zoomed in; shutter speed was 1/120 so I could open up aperture an additional stop (2.8). Not an Ideal viewing angle but I like the colours and the light. The plane of absolute sharpness is a bit too close to the camera, sharpness dropps noticeably towards the window.
DVX100B in squeeze mode and progressive (PAL 720x567), blown up to 1280x720 with Compressor. Gamma setting Cinelike-D.
