Mapping Democracy - 100 Jahre Demokratie(-Bildung) in Hamburg
Das Jahr 2019 ist sowohl für die Universität Hamburg als auch die Demokratiebewegung und das Frauenwahlrecht in Deutschland ein besonderes Jahr. Vor genau 100 Jahren – in der Zeit des demokratischen Aufbruchs nach dem Ersten Weltkrieg – wurde die Universität Hamburg gegründet. Diesen aktuellen Anlass hat das Team der HOOU@UHH aufgegriffen und in diesem Projekt thematisiert. Ziel des Lernangebots ist es, ein partizipatives Lehr-/Lernarrangement als OER bereitzustellen, das die Demokratieentwicklung in Hamburg im Zeitraum von 1919 bis 2019 in den Fokus nimmt. Dabei sollte auf vorhandene Quellen zurückgegriffen werden, um Varianten der sogenannten „Remixe“ zu realisieren und zu erproben und damit die Nutzung vorhandener Materialien im öffentlichen Raum (z. B. für Ausstellungen) zu unterstützen.

EcoTerrabot – Open Robotics for Agriculture
The EcoTerrabot project started as an idea to deal with the issue of increasing use of agrochemical pesticides in agriculture. This motivation behind this was the harmful effects of the pesticides on human and planetary health in mind. The idea was to work towards a non-chemical solution to the problem of weed infestation in agriculture. The magnitude of this challenge can be gauged from the fact, that in 2018, the total pesticide consumption worldwide amounted to 25 billion Euro (30 billion US$). Furthermore, the use of pesticides in agriculture has increased manifold in developing countries in the last couple of decades, owing mainly to the increasing dependence of the genetically modified crop varieties. On the other hand, the organic food market is growing continuously for the past decade or so and is currently placed around 12 billion Euro (15 billion US$) in Germany alone. Given the negative effect of pesticide use on the environment and the growing market for organic food products, an intervention such as the EcoTerrabot seems like an idea whose time is now. This idea started with the master project work and subsequently the master thesis of Durga, the team lead, supervised by Prof. Otterpohl and his PhD student, Tavseef, who is part of the team, with his agroecological studies background. Niklas comes from a family farm background and has studied management, bringing this expertise into the team. The idea behind EcoTerrabot is to develop a low-cost and lightweight weeding robot, which can be employed in both small farms as well as larger scale farms, for a variety of crops. The configuration can be changed depending on the type of the crop being grown in the field. The USP, so to say, of this robot is the ability to do 'selective weeding' whereby it recognises the different types of plants through machine learning and accordingly either removes the harmful weeds or incorporates the useful weeds into the soil. The first version of the robot, EcoTerrabot I, is currently under development. The necessary components have been procured thanks to the grant of 10,000 € provided by the Hamburg Open Online University (TUHH). The development and assembly of the components is kindly supported by Der Space. The components procured with the HOOU grant will be used for the development of the first prototype, which will then be tested, followed by further development. The ultimate aim being to develop EcoTerrabot on a commercial scale following the Open Source model. We look forward to your valuable comments and suggestions. Let's Go Sustainable with EcoTerrabot!

The hammered dulcimer - Video
The moment that a player lifts the hammers and strikes the strings, music is there. Have you seen this musical instrument before? (Fig.1) A percussive stretched-string instrument that needs a hammer to strike, an instrument that reveals the astonishing diversity of the world's music?This instrument is called the hammered dulcimer. On the Map of the distribution of the hammered dulcimer and possible routes of dissemination given by Grove Music Online (Fig.2), the route of dissemination overlaps with the Silk Road. (Fig.3) For many centuries, the Silk Road, the network of trade routes that connected the East and the West, was central to cultural interaction between the regions. With the evolution of history, many countries have experienced prosperity and decline, many regions have merged and split, but the trade network has never stopped contributing to cultural exchanges. It may lead us to the possibility that this instrument traveling along the Silk Road with people, was used to make some of the first "world music" jam sessions and was developed together with the trade of silk and porcelain on the journey. Now, let us explore the uniqueness of the various hammered dulcimer along the Silk Road together. According to the Grove Music Online, the hammered dulcimer has been known by dozens of different names. (Fig.4) The various names can be classified into different families and also convey some of the character of the instrument such as structure, material, and even usage scenarios within each culture. About the origin of this instrument, due to the great age, the academic circle has not yet reached a unified conclusion. Among all the statements, the prototype of santur can be seen as the earliest. Santur (Fig.5) is the Persian term in the areas that are influenced by Persian culture such as Egypt, Georgia, Greece and India. Its history can be traced back to iconographical documents of ancient Babylonian (1600–911 BCE) and neo-Assyrian (911–612 BCE) eras. Around the sixth century BC (Fig.6), santur already appeared among the instruments in the orchestra of Nebuchadnezzar. (Fig.7) Today in Iran, santur is still an important instrument in the traditional orchestra. It is also used in motrebi (music for entertainment), but almost never in folk music. It is made of walnut wood. The sides of the trapeziform case form an angle of 45° to the wider end. The players hold two light hammers (mezrāb) in three fingers of each hand (Fig.5.1). Now let’s hear a piece of Iran Santur music. (https://www.youtube.com/watch?v=-0eeq0kphY8 https://www.youtube.com/watch?v=hbcHmXcww-k) In our map of the distribution of the hammered dulcimer and possible routes of dissemination (Fig.2), the the dotted arrow north-west from Turkey to Western Europe shows us the possibility of a way that hammered dulcimer was introduced from Byzantium to Western Europe in the 15th century. The instrument then dispersed into the rest of Europe and won many different names there. In Germany, it is mostly called Hackbrett (Fig.9), its cognates among Germanic peoples are shown on the slide. ( hackbräd, hackbräde (Swed.); hakkebrett (Dan.); hakkebord (Flem.); Hachbratt (Swiss-Ger.) etc.) While the term tympanon is used in Western Europe, cimbalom is used in Eastern Europe. In 1870s in Budapest, the Hungarian concert cimbalom was designed and created by Vencel József Schunda, this innovation enabled cimbalom to appear in symphonic works and then play an increasingly significant role in in the modern music works of Hungarian composer such as Peter Eötvös. Now let us hear a piece of his music. In the Orient, (Fig. 8/8.1)on the other hand, Mandarin Chinese term Yangqin is most commonly used. One popular theory said that Yangqin was introduced to Southern China in the Ming dynasty (1368–1644) and originated from the Persian santur. Some scholars also say that the hammered dulcimer has made a detour to Europe first or it was entirely originated in Europe, then later went to China along sea-based trade routes. That is why its original name yang means “foreign”. Through China, Yangqin was further introduced to other countries in East Asian, for example Korea. Nowadays, the other character of yang with the meaning of “elevated” has come into public acceptance. Yangqin’s resonating chamber is covered with a thin soundboard of white pine or other softwoods. The hammers are springy and thin bamboo beaters with one side of the end covered by rubber. This unique construction allows players to use various technique to produce sounds with different texture. Since the mid-20th century, to adjust to the new concert-hall environment, yangqin has been reformed, both the size and range has been enlarged. Yangqin with four and half octaves and full chromaticism has already been popularized. Now let’s hear a piece of Chinese Yangqin music.
