Yes, MOST of the design could be re-used. As an Arduino shield there is no need for a PIC or RS-232 interface becusethe Arduino does that function. You'd need to replace the 74ACT175 part but that is not hard. About changing the cap values without soldering. I guess you could push the leads into a 0.1 inch header strip or install several and use a DIP switch to select which are "in". But I don't know if the extra inductance al that wiring adds is enough to worry about. -- Chris Albertson Redondo Beach, California _______________________________________________ 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.
