: I am currently trying to design a timing curcuit that
: could be controled by digital or analog output from a
: computer. It needs to vary from 4 msec to 50 msec.

: I have two thoughts. One is to use a JFET as a variable
: resistor for a monostable and the other is to use a pot
: that would be controlled with the output if the serial
: port.

: Any ideas? Does any of my approaches sound good?

Take a look at www.boondog.com
Paul has a nice design for computer controlled timing.
