Don't know the guy/gal who posted this to another list I'm on,
just thought perhaps someone here might appreciate it.  Sorry
for bandwidth consumption.

Subject: a trivial device, but I think, a useful one

I filed a patent application for an electronic gadget a few months
ago.

Those of you who do your own computer maintenance and upgrades know
how much crap builds up inside a computer sucked in by the fans.
While one can get computer air filters at larger electronics retail
stores, forgetting to clean the filter turn a recurring annoyance
into a much bigger problem when the CPU can't get any cool exterior
air. I also discovered in the course of working on this that just
because an open-cell foam filter looks clean doesn't necessarily
mean that it is.

The fix is a computer filter monitoring device, you can see it at
http://www.computerfiltermonitor.com .

I wash out the filter when the software alarm tells me to and don't
think about it otherwise. My computer stays both internally clean
and cool.

At the moment, the only available form is a bare PCB with user guide
and assembly instructions, I'm looking for an OEM. I figure that
some of you might find this useful (I designed it because I wanted
one and nobody sells anything like it that actually works) and
because I figure that anyone who reads this list is up to PCB
assembly.

It took me a while to get around to mentioning this largely because
there was a design error in the first PCB and I wanted to make sure
the bug was stomped out before announcing it.

I figure the people who can really use this are ones who spend a
lot of time working on their computers and the ones whose computers
*must* work *all* the time. While this won't guarantee that since
AFAIK, there is no way to guarantee 100% computer uptime, it's one
variable that can be put under one's control.
