Dead links removed.
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:
address for snail mail in the west of Munich is:
- Erik Baigar,
- Gotzmannstrasse, 5, 1.Og,
- D81245 München,
- Tel. (0049)89/63496363
- Fax. (0049)32/223564681
- AB (0049)321/21248233
- 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):
- Erik Baigar,
- Richard-Strauß-Straße 9
- D87616 Marktoberdorf
- 47°46'09.47"N, 10°36'38.13"E, 824m above sea level
- During the day I am working in the R&D division of
the Dionex-Softron GmbH:

- And here some out-of-date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 by the linux powered Google or DECs Altavista Searchengine.
- At eBay there are always a lot of interesting
auctions in which you can search for an item. Especially interesting for
me are auctions e.g. on
vintage Computers in the US
and in Germany.
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 here.
- 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 fond 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.
- Jet engines are rather reliable because of the many tests done on them
(see e.g. 1,
5) but sometimes (one per month currently) a
failure is "uncontained".
- 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 and offers help and freeware for them.
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,...) are 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,
the lunar landing computer,
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 (this is part of the sdcc, too).
- 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.
- For some dancing moves you can find step diagrams online at the TSV-Forstenried.
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.
