I had a very similar realization this morning when I was driving in. But you've overlooked an even easier way to use the sound card... Rather than have the CPU or RAM figure translate into a frequency, why not _amplitude_? A simple inverse log function in the 'meterd' daemon will provide the proper scaling, and the sound card's amplified audio output can drive a sensitive AC voltmeter directly, with a little resistive padding to set the meter range! The frequency idea is still not bad, expecially if one owned a nixie-tube frequency counter :) Unfortunately, those things are typically the size of a PC case. No muss, no fuss. I will handle the hardware end of this, who wants to write the code? How about the daemon should read a config file (or accept a command line argument) to tell it if it should output information on RAM, CPU or SWAP... -.bill.layer.- -.those who are talking don't know, and those who know aren't talking.- -.frogtown.- -.minnesota.- -.u.s.a.-
