I have been in the process of gathering up much of the information that I've posted on a variety of websites. You will notice a variety of information appearing here on nearly a daily basis as the material gets put together in a suitable format.
-Electronics
-Various LEDs, testing of various LEDs, and information on them
-A few side things on flashlights and related
Once I get the archived information up, I will likely be adding to the web page frequently.
Otherwise I may be contacted at leeper@molalla.net, if you have questions/comments before then.

I've decided to start adding the web pages containing the information, in a non-highly formatted fashion, to at least start putting them up. At first, these will mainly comprise some of the posts/threads I've made on various forums, stripping out much of in between questions/comments that can make threads a very long read.
Once I get a number of the informational pages up, I will then be going back and formatting things to look more like the flashy stuff you find on typical web pages, with all the jazz and everything. I hope folks find the information useful.
