By careful design of the air ducts and blower location(s), a multitude of PICs can be adequately cooled.

This is not impossible, and can be done relatively cheaply. The problem lies partly with expectations: "What would you expect the computer to do?" Even better, a small compressor could build up enough pressure, which, when expelled through a shock tube, could cause the gunge to be blown off the filter, and onto the user :-) -- Bernd Felsche, _--_|\ #include Metapro Systems, / sold \ Fax: +61 9 472 3337 328 Albany Highway, \_.--._/ Phone: +61 9 362 9355 Victoria Park, Western Australia v Email: bernie@metapro.DIALix.oz.au
