Default Wireless dial test indicator

Yes, wireless. There was an interesting article on page 38 of the 21
October 2010 issue of the trade rag Machine Design
(http://www.machinedesign.com): "Wireless test indicator measures blind
holes", edited by Leslie Gordon:

r-measures-blind-holes-1021

In short, Bluetooth meets and marries the centenarian dial test
indicator.

Default Wireless dial test indicator

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.

http://machinedesign.com/video/inven...nhoff-llc-1021
Product name : Vyndicator

Dunno why they chose to make a demo video with the sensor mounted in a drill
chuck though.
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.

The chuck is just a convenient way to mount the indicator. Its runout
doesn't matter for getting the spindle axis and bore coaxial.

I want a cordless TIG current control. It seems there's always a rat's
nest of cables underfoot when I'm welding, and eliminating the foot
pedal cable would be a big help. Would a cordless mouse work in that
electrical environment?

The received wireless mouse signal (possibly only X or Y) would require some
sort of D/A conversion, would it not?
I dunno about the EMI-RFI issues.. someone here with a PC in their shop
could probably comment on that.

A tiny low voltage gearmotor to operate the variable current pot might work,
but you could likely do it with circuitry, handy as you are with electronic
stuff.

The motor idea just popped into my gourd as I was thinking about a
stabilized output variac I have, that operates by a small (non-digital)
circuit board and a small motor.

I'd temporarily forgotten about the rotating indicator's relationship to the
spindle.. thanks for the reminder.

The generally accepted solution to eliminating the foot pedal cable is
to eliminate the foot pedal and use a torch mounted control, either a
variable control like the foot pedal, or a simple pushbutton when used
with a sequencer.

As for wireless links in the shop, I think it's workable in most cases.
Modulation methods, data rates and receiver sensitivity have improved
over the years and a data link these days can readily overcome the
variable RFI in a shop environment with redundancy and error correction.

Not what you are talking about but I think I saw an add for an amp clamp that had a remote
face that is wireless. There are many times when I'd like to put amp clamp or a dvm on a
circuit but view it while standing at the operation panel on the other side of the
machine.

Wireless gear that operates in the 2.4GHz frequency seems to be abundant.. I
dunno how much crap they can/expect to cram into that bandspace, but there's
a hell of a lot cheap 2.4 consumer stuff around (albeit weak RF).

I had a cordless phone that was interrupting the display of a wireless video
camera at intervals of about 1 second, even though the handset was on the
base unit.
I gave the phone to a friend (I don't particularly like cordless phones,
even though that one was supposedly a spread spectrum model) and the camera
worked fine in a city neighborhood environment after that.

DECT Cordless phones are 5.8 GHz.
