24 | <h3>Pianola</h3> |
---|
25 | <p>The technikum29 is quite versatile – beside all the communication |
---|
26 | and computer technology we also show very special exhibits: This is |
---|
27 | a fully executable pianola, year of manufacture about 1910-1915.</p> |
---|

---|
30 | It's a great experience see and hear such old jukeboxes, typically made |
---|
31 | only of natural materials like leather, gum, wood, bone glue, felt, metal, paper, |
---|
32 | ivory and glas. |
---|
33 | <br/>By assembling these elements on an intelligent way, one could |
---|
34 | build a simple mechanical machine which is especially impressive |
---|
35 | for today's people. Here at the technikum29, we will show you how |
---|
36 | this device works, we will explain the basic functionality and |
---|
37 | play challenging compositions. While having covers removed, you can |
---|
38 | even see the fascinating mechanics working. |

53 | <p>The technikum29 has a movie projector from 1951 (there are |
---|
54 | more and even older projectors from the 1930s that are stored in the |
---|
55 | archive for lack of space).</p> |
---|
56 | <p> |
---|
57 | Movie projectors have always been very complex devices. At that time, |
---|
58 | the bright picture projection was archived with an arc light which was |
---|
59 | generated between two carbon pencils. The waste heat was deflected via a |
---|
60 | chimney pipe! <!-- stupid mode... --> |
---|
61 | Since the pencils got shorter and shorter while the movie went on, they |
---|
62 | had to be moved continously closer together for producing a constant |
---|
63 | luminosity. Otherwise the light goes out. |
---|
64 | <br/>We will repair this device to show an original newsreel from the 1960s. |
