Story

I needed help testing parts that have tiny leads using a micro-ohmmeter.  (Cannot use J-hooks!  “Micro-ohms.”)  The micro-ohmmeter does not have a GPIB or rs232 interface, purchasing an interface card cost too much, and asking for help can be expensive, aggravating, and time-consuming.  I have been using my elbow to push a button while I hold the probes on tiny leads.   That has not worked out well.   

Anyway, I needed some form of assistance to test the parts so, I made a button-pusher called the Igvier.  …got a-lot of laughs but, sometimes the stupidest ideas can be the greatest cost and time saver as well as personal reward.
