Thanks! For this project I wanted something that sat on my desk and not up in the rack, it just fits my workflow better.

Take care,

The dip 16 chip is a BU4538B retriggerable/resetable monostable multivibrator. The dip 8 chip, of which pin 8 is connected directly to pin 3 of the BU4538B, is an LM393 dual differential comparator.
