Table of Contents


These listings and links identify those web sites where I have some sort of control and attempt to maintain up-to-date versions of all the documents where possible. Additional options may be found at the mirrors info of the Sci.Electronics.Repair FAQ sites themselves. Some Web sites get updated more frequently than others. The latest versions of the S.E.R FAQ (including Sam's Laser FAQ) are at two Web sites, which are the absolute latest and are updated almost in real-time:

Descriptions of the Various FAQ Collections

  • SERFAQ The Sci.Electronics.Repair (S.E.R) FAQ is an extensive set of documents on consumer electronics (and other) troubleshooting and repair, testing, general electronics, reference information, assorted schematics of interesting and sometimes unusual devices, links to over 1000 technology related Web sites, and more. It was developed specifically for the DoItYourselfer (DIYer) and tinkerer, hobbyist, experimenter, engineer, dentist, and poet. The S.E.R FAQ includes all of the material I have written (nicely formatted by Filipg G.) as well as many articles and references from others. To the best of my knowledge, this is the most comprehensive collection of information of its kind in the explored universe.

    Note that the latest documents I have authored (see SSTR, below) are now linked from the S.E.R Main ToC. The older versions will eventually be phased out.

  • SLFSam's Laser FAQ (SLF) - A Practical Guide to Lasers for Experimenters and Hobbyists - contains extensive practical information on a variety of laser related topics. Sam's Laser FAQ is present at all S.E.R FAQ (and SSTR - see below) sites, but due to its nature and size, is also available as a self contained document and at other sites as well. Version may vary slightly by site but all are quite recent and nicely formatted including a full table of contents, list of all associated files, and extensive cross-links. The complete Sam's Laser FAQ may be downloaded for convenient high speed local access. See: Sam's Laser FAQ Local Installation for details.

    The Laser Equipment Gallery (LEG) includes a collection of photos of various laser systems, power supplies, and components. Due to its size, the LEG is only present at selected sites and is NOT part of the FAQ distributions.

  • SSTR Silicon Sam's Technology Resource (SSTR) includes all the documents I have authored and are now linked from the main S.E.R FAQ ToC. They are nicely formatted and eventually the older similar documents of the S.E.R FAQ will be phased out. In other words, the latest versions of the S.E.R FAQ documents I have authored ARE exactly the same as what's in the SSTR directory. The complete SSTR collection may also be downloaded for convenient high speed local access. See: Silicon Sam's Technology Resource Local Installation for details. Note that while SSTR sites include Sam's Laser FAQ, it is NOT part of the SSTR download package and must be installed separately.
  • Copies of some of these documents, particularly the various repair guides of the Sci.Electronics.Repair FAQ, may be found at other totally independent sites. However, unless they are live links back to one of the sites below, the versions are likely to be quite old (relatively speaking, at least). There are also some additional sites which have copied and modified some of these documents to provide a more user friendly graphical user interface. So, if you stumble across something that looks vaguely familiar, you will know where it came from. In either case, if there is no acknowledgment of the origin in the links or at the beginning of the document, please let me know!

    The Main Table of Contents (ToC) links, below, are the usual jumping off points for the good stuff for on-line viewing. :-) Those labeled as 'Zip' may be downloaded as a single compressed file and easily installed to create a local browser accessible copy. See the descriptions of the FAQs, above, for links to installation instructions.

    Sci.Electronics.Repair FAQ Home Site

    The latest versions of these documents are available at the Home site, Repairfaq.org.

    (SSTR=Silicon Sam's Technology Resource, SLF=Sam's Laser FAQ, LEG=Laser Equipment Gallery.)

    Sci.Electronics.Repair FAQ Mirror Sites

    These sites have various versions depending on who maintains the content. For those where I have upload access at least, versions will be quite recent. UPenn is my "live" site - it's where I do all development and is thus guaranteed current (complete with screwups). Repairfaq.org and Drexel are updated from UPenn almost daily. Hopefully, some sites will have fully automatic mirroring but that is in the future (I've been saying this for about 10 years now!).

    The primary mirror sites (Drexel and UPenn) are listed first, followed by the remainder in no particular order - maybe alphabetic, then EDU/COM, then USA/Foreign, then by distance, maybe. :)

    (SSTR=Silicon Sam's Technology Resource, SLF=Sam's Laser FAQ, LEG=Laser Equipment Gallery, Zip=Zipped file for the preceeding FAQ collection.)

    The entries marked 'Zip' provide a convenient way of creating a local browser-accessible copy of SSTR and/or Sam's Laser FAQ. See Silicon Sam's Technology Resource Local Installation and Sam's Laser FAQ Local Installation for details.

    Sci.Electronics.Repair FAQ Archive

    The complete Sci.Electronics.Repair FAQ (including information and links from other sources) may also be downloaded from the Circuit Cookbook Archive (CCA) sites. Both ASCII and local HTML versions are available but they are generally older than those at many other sites:

    Sci.Electronics.Repair FAQ Italian Translation by Antonio Cristiani

    Most of the individual repair and testing documents (but not Sam's Laser FAQ) have been converted including the colloquial English phrases!

    Sci.Electronics.Repair FAQ French Translation by GUILBAUD Christophe (Tophe)

    Portions of some of the individual repair and testing documents (currently just TVs and VCRs) have been converted. This site seems to have disappeared (surprise, surprise!). If anyone knows where it went, please contact me.

    Additional Sites with Sam's Laser FAQ

    In addition to being included in the S.E.R FAQ and SSTR sites, there are several other sites which include Sam's Laser FAQ (SLF).

    Miscellaneous Sites with Sam Stuff

    A variety of documents that I have authored or coauthored are available on: Don klipstein's Lighting Technology Web Site. (Most of these are also part of the S.E.R FAQ and SSTR collections.)

    One of the latest versions of the document: "Notes on the Troubleshooting and Repair of Electronic Flash Units and Strobe Lights, and Design Guidelines, Useful Circuits, and Schematics" usually resides at:
