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.

'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.

How the heck do you drill 0.005" diameter holes?
Looks awfully difficult to control even with a huge #80 bit:

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

BB your the winner!
I thought .007" EM was it, I milled (picked corners) in graphite. I
was amazed at how they even can make EM or drill that small! IIRC I
broke one just putting in the collet.
#80 drills in a pencil grinder for vacuum holes in blow molds-in AL&
brass- by hand. TIP: I made a 1/8 collet adapter by drilling &
inserting 3 small pins into a .120 disk, naturally stratgically spaced
at 120deg.(alot better than wraping shim stock around them- nobody
does that!LOL)
Lots of holes in vacuum formed cavities. Nice part is if you break
one (rarely) just move over a bit & keep drilling. The hard part was
re-sharpening them.<g> Think JB's darex with optics will do it?
ROFLMAO
The other fun part was milling the vacuum slots on the underside.
They !should! be within 1/4" of the cavity shape. We did'nt have to
much CAD/CAM info at that time, it was hand codeing off "blue prints"
Ah....... the smell of ammonia in the design office. = "Gentlemen
start your band saws" Damn mold biz. They were always late by the time
the prints were released. They designer (IMO his prints were works of
art they could be scaled-if the humidity was down) would never let us
start till they were "checked" Come on! just sqr. the blocks 1/2"
oversize in height. Always height because of unseen shutoffs.
Steel's cheap! Time consuming is squaring/water lines/screw holes & KO
pins. Damn...... ever build a mold "backwards"? We did. Customer calls
me, had the molded parts in his hand out in Iowa- "You built the mold
backwards" I've never been so embarrassed in my life! The guys said
they could see light thru my ears they were so red.<g> Damn! crisper
drawer face for a fridge. So what? if the lettuce can't get air<g>
Make it the England model- they are on the left side anyway<g>
Could'nt weld that one. High diamond / texure finish cosmetic part
would show like a sore thumb. Customer did not want a seem line for an
insert, plus water lines right under it. What to do? We fixed it......
its was quite simple .......Any suggestions?
Naturally nobody cought it initially , we were under the gun to get-
r- done. Outside designer - never got paid, & he was mad! The worst
part was the Boss was on vacation & we had to fix it ASAP. Like NOW.
Drive to Iowa, bring it back,fix it, drive it back, so not to loose
the "very good" customer, all before the Boss gets back= less than 1
week. It was the true meaning of "assholes & elbows"
Ah the AutoCad 9 days. What ever happened to 5,6,7,8?hehehe

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?
That's just silly small.
--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.

On YouTube, all the tools have volume controls.
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?

Why not? Drive-up ATMs have Braille keyboards.

Actually they are not optional (at least any more), they are the
standard. The American Association of State Highway Officials specifies a
30" wide. red stop sign with 3/4" white border. Most states, including
Ohio, have adopted these standards.

"Approximately ten percent of those deemed legally blind, by any measure,
have no vision. The rest have some vision, from light perception alone to
relatively good acuity."
If I were a caregiver for a partially sighted person, it'd be convenient
to have them use the ATM from the driver side passenger seat. The Braille
would be a good 'parallel information path'.
I can 'see' that. :)

That's because they use the same keypad in walkup ATMs. It reduces
the inventory needed for service work, and the chances of being out of a
Braille keypad when needed. I used to work next door to a Diebold
service center, and talked to their techs when I was on break. They
have guaranteed response & repair times in their contracts with banks
and all of their other equipment. That is why most repairs are done at
the assmbly level, rather than the component level. I used to get
dozens of two year old gel cells for free from other bank equipment
repair people that were replaced before they had a chance to fail.

FWIW -- I have some color slides (Kodachrome) taken about 1962/1963 in
Cambridge Mass, which show stop signs of traditional shape and
pattern (e.g. octagonal, with the edge stripe), but the main
field is yellow, not red, and the letters and border stripe are
red.
I don't know whether this was true for all of Cambridge at this
time, or only the MIT campus and surrounds, which is where the
shots were taken.
Enjoy,

I have a vague recollection of the stop signs changing when I was kid
in eastern MA. I was 10 in 1962, so I wouldn't be surprised if there
were still some stragglers at that time. Or, you've just implanted me
with a false memory <g>.
