…and almost 20 years
later, we have a new website host at google sites :) Most of the content has
been transferred right now, so there is going to be stuff missing, irrelevant,
or wrong. Enjoy!
02-23-2006
Added 1% and 5% EIA Excel
rounding formulas for calculating component values. See projects.
10-28-2005
Added my PGP public key
signature to this website. See the bottom of this web page for it.
09-18-2005
Put the website back up on
tripod for now, until we get a more permanent post. My sincere pardons for the
terrible ads.
07-13-2005
Added DS4 for the
Universal Excel EIA Formula under projects.
07-08-2004
Designed the new website.
This one is quite primitive but gets the job done without java or GIFs. Also, I
got rid of the counter. If you run into any snags, please let me know.
04-25-2004
Added a few links.
04-15-2004
Moved some stuff around on
the server, and 3-pole lowpass app sheet v1.3 is where its supposed to be now. Also added a highpass version
of the app sheet as well.

Finally got around to
correcting a few things on the site. Hopefully it will load quicker for you!
I'm still messing around with my network and things, so updates will be pretty
lean for a while until I get the *real* web designed here :) -jp

Got rid of the
excessively large GIFs for BEDNET and under construction.

Corrected the

Corrected some
things in the 3-pole app sheet, which is at v1.2 now.

Replaced the MS
counter with one from http://counter.balt.net

Just got the
homepage up and done. All the other subpages are under construction. Also,
bought a new router and motherboard to make all run smoothly. If you hit a
weird snag write me back at the webmaster email.
