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

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

35 | <p>The technikum29 motivates activities that get awards and prices. The latest |
---|
36 | example is that of the young artist Leander A. Schwarzer who transforms |
---|
37 | everyday things into pieces of art. He has developed pictures made from zippers |
---|
38 | that can be opened thus giving the viewer the opportunity to modify the picture |
---|
39 | itself.<br> |
---|
40 | His latest visit to the technikum29 has inspired him to make art from |
---|
41 | and with punch cards which were the basis of industrialization in the 20th |
---|
42 | century. First the "Terzett" (Trio) was created which consists of three punched |
---|
43 | cards with these irreversible sentences:</p> |

58 | <p>These cards were hanged on a wall at a distance of 1-2 cm. During the day sun |
---|
59 | rays create shadows of the punched and coded text on the wall behind the cards. |
---|
60 | This work of art was awarded a price at the 32th grafics competition in Austria |
---|
61 | (Innsbruck, 2011). This in turn motivated Mr. Schwarzer to continue his work |
---|
62 | with punched cards. He spent several days at the technikum29 punching excerpts |
---|
63 | from Marx' "Capital" thereby creating a pile of several hundred cards. These |
---|
64 | were shown in the exhibition "A Symbol of Freedom" in Piacenza (Italy). Punched |
---|
65 | cards transform contemporary slogans into visual paradoxes when they create |
---|
66 | their unique shadows.</p> |

72 | <p>Another work, "Fetish Character of commodities", concatenates the cards |
---|
73 | containing Marx' text fragments. This string of cards is then pulled through a |
---|
74 | mechanism like a musical clock that generates sounds controlled by the holes in |
---|
75 | the cards. So, finally, the "Capital" is transformed into atmospheric sounds.</p><br> |

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