Blind Car Drivers?

(...)

Blind drivers? How many do you need? We're giving 'em away!

How about a back cushion that indicates the presence of obstacles to the rear and sides? That tailgating Kenworth could give me a back massage!

Winston:

Some Calif. drivers seem to be in that condition already.

We use to do prototype work for "Second Sight", a company that was involved with trying to return a modicum of sight to those that became totally blind. I've drilled 100's of .005" dia. holes in small plastic wafers that supposedly acted like a crude retina, and other related devices. Interesting work.

Will it work on chastity belts?

Then there are the "vibrators"--depends where they are placed--and intensity (and density)....

The car may not make it out of the parking space, but the driver (ahem !!!)...

'Way too many, Bob. I had this fantasy of handing out white canes at stop lights.

Then I realized that many don't even see the stop lights.

Cool!

I imagine that in a few decades, we'll understand visual processing in the brain well enough to stimulate the visual cortex directly, to produce full-color, high resolution images.

Yeah, just implanted chips for phone, TV, internet, perhaps increased memory. Maybe even a college education on a chip, eh. Cyborgs-R-Us. Resistance is futile. LOL

Its all in the BIOS, has been for years. Big brother can watch if he wants to, with the "right" commands - no firewall, anti anything can stop it, short of pulling the plug.

Ah......... the Universe/Modern Marvels on History channel- much more interesting.

~g~

But seriously, Bob.

How the heck do you drill 0.005" diameter holes?

Looks awfully difficult to control even with a huge #80 bit:

--Winston

W:

Normally for small holes we use carbide circuit board drills with .125 shanks. But for this particular job I used a cobalt .005" drill in a small Albrecht drill chuck so I could hold it stubby. It was only going about 3 diameters deep (.015), in plastic. Programmed it at max RPM (10,000), and .001 pecks, feed at .5-1 IPM Hell we've even MILLED with .005 dia. end mills. LOL

(...)

That is impressive, any way you cut it.

--Winston

W:

Why thank you.

There is an example of small endmilled slots on the bottom of a cross shaped part on the bottom left picture on the first page of my homepage. I don't remember their dimension after all this time, but they look pretty small. LOL

Beautiful work, Bob!

--Winston

This is old news, and there are much smaller endmills made by someone now, but these Jabro endmills (down to 0.004") were coated and pretty slick:

That's 'way tinier than I'm comfortable with.

Did you see the 4 tenths diameter cited by Bob?

--Winston

Yeah. It's hard to believe it can cut. It doesn't look like the core is strong enough -- in fact, it seems to have no real core.

Those Jabro milling cutters were (or are -- I haven't kept in touch with them) a delicate balancing act between core strength and cutting lip, requiring perfect feedrate control to cut without jamming into the core and breaking. They work like real milling cutters, rather than engravers.

(...)

Feed control would be easy for folks who can hear the sound of individual molecules being popped out of the matrix. :)

At that scale, swarf is more likely inhaled than tracked into the hallway.

--Winston

I used to routinely drill holes from .001 to .003 with watchmakers spade bits!

That'll be the thing I learnt today. Thanks!

I grew up in Cleveland, OH. up there, stop signs with white borders are optional.

Maybe it is an 'education thing'. Perhaps I should print Driver Handbooks in Braille?
