A PantoProbe is a classic pantographic mechanism which lets you position an electronic probe with much higher precision than you would be able to position it by hand. This lets you use your meter/scope to take measurements willy nilly all over the place, not just at places that already have easy access with a test pad or via.   I built the above board, but I couldn’t trouble shoot it.  So I invented  the PantoProbe.  It made the impossible possible.  Having used one, I’m never going back.

Because it takes some tools and time to build a fully featured probe, I also designed a simple one called the PantoFlex that uses the flexing of the printed material instead of fancy joints.
