LED Driver List

  • A fully searchable list of commonly available LED drivers. Maintained in a database with more than 1,350 entries, and several have multiple configurations or versions.

    The parameters for LED driver searches are passed in the URL so it's easy to bookmark the results of a particular search (although getting Google not to hit it up for gigabytes of downloads each month was a mission). If bookmarking a URL you can just use the parameters you want and delete the ones you don't.

O-ring, Tailcap, Cable Grommet & Silicone Grease List

  • A searchable list of commonly available silicone o-rings, tailcaps, cable grommets and grease. More than 370 items listed.


Inventions & Fabrications

 
 


 

  • LED Torch (LED Flashlight). How do I make something useful from a pathetic little torch? 5 October 2004, last updated 13 May 2009.

    (FYI - a torch is what Americans call a flashlight. But those Yanks are crazy anyway. If they say "I've got gas in my pickup" or "I'm fully gassed up" they're not talking about gastrointestinal rumblings. I've added a bit of history on the term "flashlight" to the page.)

 
 
  • Car interior lighting. Every so often I get sufficiently annoyed with the feeble lighting inside my car that I do something about improving it. 18 December 2007, last updated 8 November 2010.

Swimming Pool Maintenance

  • Chlorine Shock Treatment. What it's all about, what to use, etc. This article stemmed from frustration about ridiculous and sometimes stupid advice given by pool professionals (and others) who should know better. Last updated 16 December 2001.

  • Non-Chlorine Shock Treatment. By using a non-chlorine product to shock your pool you can save money and time. Last updated 16 December 2001.

  • Chlorine Stabilisation. Unfinished, sorry.
