The Berlin quantity didactics clock


The Berlin-Uhr

*
What is the Berlin-Uhr?
The Berlin-Uhr or Berlin clock is a city chronograph, with its mast about 5 meter high, working according to the principles of quantum didactics, showing the time with red and yellow lamps, was developed by the inventor Dieter Binninger, and its located in Berlin (as you might guess).
*
This thing still exists? I thought its broken.
The Berlin-Uhr has from time to time some smaller or larger defects, but it still exists and is placed at the Europa-Center next to the entry of the tourist information within the Budapester Straße.
*
Haven't I seen it else where, once?
Yes, maybe. The Berlin clock was originally installed in 1975 at the Kudamm (Kurfürstendamm) next to the subway station Uhlandstraße. Since 1996 its standing at its current location and is financed by the merchants of the Europa-Centers.

The Berlin-Uhr as a model

*
Are there any model versions of this clock?
Yes. (For a picture see the Berlin clock page.) There was a table model, about 20cm high with seven different case colors, besides others dark red, dark green, dark blue, black, and antrazit (dark grey). Additionally there was a wall clock much like the original (ca. 1:4) and a picture clock.
*
Gosh! Must have! Where?
The orginal models are not produced anymore and therefore not sold anymore. The only locations where to find such items might be at second hand markets or online auctions. But: see below about more info.
*
There is no new table model available anymore?
The last one I saw was in 1999 in a souvenir shop within the Europa-Center. Even this shop doesn't exist anymore.
*
What was the price of these models?
The price of the table models were through all shops and variants about 150 up to 200 Euro. I think the picture clock was somewhat cheaper with a price of about 100 up to 150 Euro. I have no idea about the price of the wall clock.
*
My clock is blinking like the sinewy logo aside. Is it broken?
No. If all lamps of the clock are blinking together in a two-second-period, then there was only a power-outage and the clock has lost the time. You only have to set the time, again.
*
Help! My table model of the Berlin clock is broken! What's up?
No idea. - If it is the same error as described at the Berlin clock page (flickering and feeping), then one of the capacitors is broken and can be replaced. I can't say anything about other defects.
*
Help! My table model of the Berlin clock is broken! Where to repair?
Nearly no idea. - If it is the same error as described at the Berlin clock page, then principially any electrical engineer (or miniature train fan with experience in soldering) can repair it. Other defects are probably more difficult or beyond any repair.

Help! My table model of the Berlin clock is broken! Where to repair??? Please!
Well. I got an eMail that the ESL GmbH · Gersdorfstr. 41 · 12105 Berlin might be the followup repair service for the Berlin clock in Berlin. (2003-05) According to another information, this firm doesn't exist anymore. (2004-01) See below about more info. (2007-04)

Help! My table model of the Berlin clock is broken! I need a wiring plan!
I have a plan now. It was provided by Corey Hatch in two pages. (page 1 / page 2) (2007-09)
*
Help! My table model of the Berlin clock is broken! Is it difficult to repair?
Well. If it is the same error as described at the Berlin clock page and there are the slightest experiences in soldering (I'm computer scientist, and for me it worked after the second try), then the most difficult actions are the de-assembly and re-assembly of the plastic case. There might be a risk that this case might crumble... a bit. ;-)
*
My dream is a radio controlled GPS+Altimeter-Berlin-Wristwatch...
Well. - According to a Berlin-Wristwatch: there was a wristwatch computer prototype with color display by IBM working with a Linux operating system. Principially the X/11 application of the Berlin clock should work on this thingy... you only have to make IBM to sell it.

The Berlin-Uhr as a program

*
Isn't there any program for Windows?
Ugh. - Ehh... if this "Windows" has a Java Development Kit (JDK) installed, a related AppletViewer should exists, too. And with this the Berlin clock applet should work under Windows.
*
But I would like a Windows application...
Ugh! - Ehhh... there are probably one or the other around somewhere. - The applet per se is a platform-independent application through the AppletViewer.
*
I'm not so much a computer freak...
Then maybe any description is too difficult. Basically the to do's are: Saving the applet class and the HTML page of the Berlin clock, maybe stripping the HTML page with a text editor from its text only leaving the header, the body, and the applet call within that page, and then calling this page with the JDK AppletViewer. (Yes, you're calling the AppletViewer with the HTML page!)
*
But I would like the clock on my desktop after Windows is up...
Might work. The JDK AppletViewer might be autostart capable. I'm not so much a Windows freak... ;-}
*
Does this work on my Mahahac?
Yes! Easy, ey! Under MacOS X. The AppletViewer is already there. Saving the applet class (or even compiling the Java source), saving the HTML page of the Berlin clock, maybe stripping the page with a text editor, maybe even vi under the terminal application, and then calling the page or opening it with the AppletViewer. I've done it, too. Voll cool, ey! B-)
*
Does this clock also exists for a palm computer?
Maybe. Once before my own palm computer got broken I saw a clock within a software list, where the description sounded very much like the way of a Berlin clock.
*
Isn't it possible to do that in JavaScript?
Indeed. The page presented by the technokraten (Rüdiger Appel) The technokraten present the Berlin-Clock has a JavaScript version of this clock and some more information (in German).
*
Where do I find more info about the Berlin clock?
The page www.berlin-uhr.com really offers the Berlin-Uhr as a table model, wall model and even as a standing clock. (2007-04) Even a repair service for older models is offered. - The Berlin-Clock can be also found in the German version of Wikipedia. - The page by Manfred Fröhlich provides some more pictures and some informations.(2007-09) - Also maybe Google might help.
