    910                Prinzipiell bieten wir je einen Workshop mit dem Themenbereich "<b>Computer History</b>" oder "<b>Kommunikationstechnik</b>" an. Diese eignen sich für technisch interessierte Gruppen und Menschen, die einfach nur neugierig sind und sich in der Kulturgeschichte der intelligentesten und wichtigsten Werkzeuge, wie Computer und Kommunikationstechniken, weiter bilden möchten. Sie müssen sich zwischen diesen Themen entscheiden, da beide Gebiete in einer Führung mental überfordern würden und zeitlich nicht realisierbar sind.

    33 <p>Microcontrollers revolutionize
    34 and influence next to everything. How can schools participate on these
    35 developments and perform successful and interesting projects?<br>
    36 Six pupils of Q1 (12th year in school) of the Albert-Einstein secondary
    37 school were looking for a suitable idea for their so called "project
    38 week". This project should be connected to mathematics, physics and/or
    39 computer science. This is where the technikum29 got involved. The idea
    40 the pupils came up with was to connect technology from the 1950s with
    41 modern equipment of 2012. Communication spanning time and technology.<br>
    42 <div class="box left">

    44        </div>
    45 <p>Traditionally such projects required knowledge only accessible to
    46 computer scientists, engineers and the like. Often they had to spend
    47 weeks of reading data sheets, writing cryptic assembly code etc. How
    48 things have changed! Since 2009 a cheap and versatile module named
    49 "Arduino" is available - a controller based on the well known ATmega
    50 328 chip featuring 32 kB of memory. Arduino boards are designed not
    51 for the expert but for the layman and are the perfect base for
    52 creative people, artists, designers etc.
    53  <br>
    54 This project focuses on connecting computers to the "real world". The
    55 small Arduino board can be programmed to be used as an interface for
    56 nearly everything. The pupils decided to connect an early fax machine
    57 (a Siemens KF108 made in 1958) to a modern PC.   <br>
    58 This fax machine is based on a rotating drum which holds the sheet of
    59 paper to be transmitted to the receiving station. The picture is
    60 scanned in a spiral movement by a photodetector that slowly moves in
    61 parallel to the axis of the drum. Of course, this is incompatible with
    62 more recent fax machines.
    63 
    64 The Arduino was planned to act as the interface between this historic
    65 device and a modern PC. Thus the pupils first had to learn how to
    66 program such a micro controller which turned out to be quite difficult
    67 for non-programmers. Nevertheless the software approach has its
    68 advantages: It is more easily debugged compared with a traditional
    69 hardware based interface. Thus it only took a single week to program
    70 and interface the Arduino board to the Siemens fax.
    71 
    72 <div class="box left">
    73         <img src="/shared/photos/kommunikationstechnik/arduino2.jpg" width="606" height="354" />
    74        </div>
    75            
    76 <p>The fax machine generates an auido signal with a frequency of 1.5 kHz
    77 denoting black pixels to be transmitted. To convert this into a binary
    78 signal with a 5V level an amplifier circuit is needed that is followed
    79 by an RC-combination. In addition to that a synchronization signal is
    80 necessary to signal the start of a new line being scanned. This is
    81 generated utilizing a reed-contact that is triggered by a so called
    82 "super magnet" that has been glued onto the axis of the scanner drum.
    83 The reed-contact thus generates a signal for every revolution of the
    84 drum which corresponds to a single line being scanned.<br>
    85 
    86 The control program for the Arduino was developed by the pupils (the
    87 source code can be found <a href="/de/lernprojekte/arduino-projekt-programme/"> >>HERE</a>). It allows the picture being scanned, a historic Mickey-Mouse drawing, to be transferred to the PC
    88 where it is displayed slowly line by line with good resolution.
    89 
    90 The experiment was a full success and will inspire future projects.
    91 
    92 <p class="small">*) Arduino: The name of this board derives from King "Arduino of
    93 Ivrea" who lived in medieval times in northern Italy where the
    94 controller was developed.</small> <br>
