The most important reason for generating one's own (private) home-page
in my opinion is to allow others to look up my address:
The most effective way to contact me is to use
Nearly every day I check for SMS:
My address for snail mail in the west of Munich is:
Gotzmannstrasse, 5, 1.Og,
48°09'30.82"N, 11°24'42.62"E, 570m above sea level
On Weekends I am sometimes in Marktoberdorf (100km from Munich in the beautiful Allgäu):
47°46'39.6"N, 10°37'17.3"E, 732m above sea level
During the day I am working in the spectrocopy group of the
development division of Thorlabs GmbH:
Dr. Erik Baigar
Scientific Lead Spectroscopy Systems
Münchner Weg 1
48.275085°N, 11.471347°E, 540m above sea level
And here some out-of-date
Another nice feature of a private home-page is that you can have bookmarks
of pages you often use available on the net. So here are my bookmarks:
- Search the WWW using Google, formerly DEC's Altavista searchengine, the green
Ecosia or the non-tracking DuckDuckGo.
- At eBay there are always a lot of interesting
auctions which can e.g. searched for vintage avionics
and there is a German offspring of eBay, too.
- LEO offers a lot of software and quite acceptable German-English or German-French dictionaries.
- For a survey of films in Munich's cinemas click here,
movies shown in Kaufbeuren's Corona are listed here and for info what's tonight on television look
- The Musikhochschule Muenchen often offers excellent performances of old and "new classical music.
- Using public transport in Germany can be planed by using the electronic enquiry desk of the Bahn AG.
- The local public transport in Munich, the MVV and his help-desk are not so bad as many people say.
- Some nice ASCII-ART is always allowed - in today's perfect and
megabyte consuming world they bring a nice diversification.
- A nice point to start a search for many nice topics about electronics - e.g. Sam Goldwasser's FAQs.
- A nice collection of links can be found on the HF-Pages.
- Following pages deal with HF: Look at SOMIS' for practical (ham radio) issues.
- Looking for data-sheets try the following links:
The famous Chipdir,
Semiconductor Data-sheets, the
Data-sheet catalog, the
and AllDataSheet. But in my
opinion, the best database currently is
datasheets360 since it offers
direct access to many pdf files, works with all browsers, is not bloated
with Ads and it lists lots of vintage parts, too!
- Agilent (HP) has some
of the manuals and schematics of their cool test equipment online now.
- Some nice projects (some related to vintage computing) can be found on
SparetimeGizmos or if you want to
build a spectrum analyzer, look here.
- LRZ-München, Munichs top Computer facility.
- A useful whois-Database for several debugging purposes or a domain checker and a
MAC lookup tool.
- SGI made very nice MIPS based computers running IRIX. For older OSes (5.3), the tgcware is very handsome.
- Manly PC-Computer hardware projects can be found here - useful e.g. for getting pin-outs!
- FAQs regarding UNIX systems (SUN, SGI, HP,...) untun 2013 have been available on Pimpin' Networks!
- PvMegaPOV is an extension to the multi-platform render program povray.
- Some interesting reading about minimalistic languages, e.g. the TinyBASIC.
- Vintage computers are a nice topic since they show how ingenious designs and ideas set the bases
for today's horrible colored and bad M$ software: PDP8, Bitsaver-Archive,
performance database, a online and freely accessible Cray
and last but not least ClassicComp Archive (Transputers, Helios and much more).
- Software development for older processors in assembler (e.g. 8051) and other architectures is much easier in
using the know how from the WWW: Programmer's heaven. A very nice
cross assembler for Z80, Cosmac, 6502 and many others is the asxxxx (nowadays this is part of the
- Nekochan is a great knowledge base for SGI machines!
- UNIX offers many powerful tools, but you might want to look into these manuals on how to use
them: SED, regular expressions
- The karate Dojo 1.MKC has it's own home-page as well as
the new Dojo of Shihan Lowinger in Haldenwang
and the German karate association.
Nice movies (mpeg) of the Kata practiced in the Shotokan style can be seen online.
- Weather-forecasts and satellite images are available from the Klimarechenzentrum.
Actual information on the weather and the possibility of avalanches in Switzerland
and for Germany are available online.
- The home-page of one of Germany's best info stations, the Deutsche Welle is available here.
- In the alps near my homeland there is a nice school for climbing mountains.
They have nice mountain guides and maps as well.
- Climbing guides are available in the Edition Filidor.
Scientific (and hobby scientific ;-) ) Links:
- Patents are an important factor -do online searches in the US patent office or even better via UK's intellectual property office.
- One of the worst aberration of science was the invention of nuclear warfare.
- Look at the hobby-Scientific-page and a nice mailing list regarding Tesla coils lies on the WWW, too.
- Other interesting links concerning physics:
- Publications in OSA-Journals
- The Weizmann Institute
provides links to valuable atomic physics
- A how-to on building an Inexpensive X-ray Machine was published by the
Scientific American in the sixties.
- Several Databases might be useful. Check out web-elements,
mat-web. And if you have a spectroscope, the a database of the
visible spectral lines is a must.
- Lasers are interesting toys and building one at home is not that difficult. Look here for HOWTO's.
Companies, mainly electronics:
Links to home-pages of other people I know (not only via cyber space):
- LABX and Capovani are pages dealing with used optical components and lab equipment.
