Probably a really cool device, although the photos in the article don't show
much.. but there's a video (click on pic of the instrument on a mill table)
that shows actual use of the instrument or this link.
name : Vyndicator
Dunno why they chose to make a demo video with the sensor mounted in a drill
Apparently the chuck is an accurate one, because they do demonstrate
centering a hole in as axial indicator demo.
I've been anticipating wireless oscilloscope and DMM probes for quite a
while.. they may exist, but I haven't actively been searching for them.
Years ago (80s?) Beckman had a mini DMM that was about the size of a logic
probe, and later a scope was available of the same size, although the LCD
screen was smaller than a standard postage stamp.
The very tiny/thin nano-scopes are somewhat amazing, but they're limited in
several ways and appear to be too complex for me to want to try to use them
for real world applications.. trigger, sensitivity, position etc are all
touch controls (which experienced video game players may have an easy time
using) but way too small of an instrument for me to be comfortable using.
My portable scope is a Tek Meter LCD true RMS DMM autoranging scope which
uses standard sized meter probes and BNC scope probe. Real buttons (no
knobs)5x2.5" screen and fairly easy to get comfortable using.
