Bernd Ulmann	At the VCFE 2006 in Munich I performed a talk covering the development of analog and hybrid computers at Telefunken. The slides for this talk can be found here (about 4.5 MB). Also at the VCFE 2006 in Munich I had a second talk covering the basics of analog and hybrid computing. The slides are available here (ca. 3 MB). Yet another talk at the VCFE 2006 in Munich gave some examples of problems with their solution on an electronic analog computer. The slides may be found here (ca. 650 kB). In the summer term 2008 I gave a talk at the University of Hamburg with the title "Faszination Analogrechnen". The slides are available here (ca. 3 MB). Also in 2008 I delivered a talk at the University of Hamburg about Helmut Hoelzer's work in Peenemünde which eventually led to the so called Mischgerät and the first truly universal electronic analog computer which was completed in 1941. The slides for this talk can be found here (ca. 1 MB). On 27-MAY-2009, I will deliver a talk entitled "Think Different - Think Analog" at the Kolloquium des Lehrstuhls Medientheorien on the HU-Berlin. The slides for this talk can be downloaded from here (ca. 700 kB). On July 9th, 2009, I had my final examination for my Ph.D. (the so called "Disputation") - the slides for my introductory talk can be found here (about 36 MB).
Dr. F. Vogel	Dr. Vogel wrote a great introduction to analog computing which can be found here (in German, 1.7 MB). Dr. Vogel also built a wonderful small electronic analog computer which is ideally suited for teaching. The documentation of his analog computer can be found here (in German, 2.2 MB). Since my conversion of Dr. Vogel's original Word documents to PDF was erroneous and deleted the first page of the schematics, the two page schematics of his computer can be found here for download. In 1977 Dr. Vogel completed his dissertation about a genuine new resolver design without complicated diode networks. This is a very interesting approach and his thesis contains detailed schematics of his new resolver design. The thesis can be found here (about 17 MB!).
