Subject: The $45 "El Cheapo" Oxygen Analyzer
Last weekend I built an O2 Analyzer based on the design in the O2
Hacker.  As some of you may have found out, the PM128s have been
modified just a little enough to give the non-electronics types a minor
headache.

The O2 Meter should cost less than $45 to build.  This does not include
the price of the sensor (add $60 to $90 depending on what sensor you use
and where you get it from).

I built a quick and dirty web page consisting of a part and tool list,
and some detailed instructions along with a few photos.  Hopefully, it
will clear up some of the questions out there.

I could not figure how to link the three pages due to a lack of HTML
knowledge (or desire).  However, each page does list the associated
pages (you'll have to cut and paste).

If anyone is interested in viewing the pages, they follow:

Main page:                http://home.beseen.com/sports/mk15/index.html
Part and Tool List:
http://home.beseen.com/sports/mk15/PartsTools.html
Instructions:
http://home.beseen.com/sports/mk15/Instructions.html

Cobber ... if you think it is worthy, feel free to link it to your site.

Private comments are welcome.

Patrick
