If you need a simple/cheap pollable ADC, there is a Velleman kit available with USB. Can sample ADC, and a number of discrete inputs as well. And it can now be found on the wall at Radio Shack, strangely enough. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
