A "click to select" multicolor marking pen, with relatively
point tips. Ink needs to be non-electrically conductive,
semi-permanent, and able to mark metals and plastic
equal tenacity. The colors should be glaring bright,
to glow more brightly under UV.

around them) with bright spots of color. It's all well and

A magnet (flat sheet style if available) is your friend.

theres often some black 1mm long, 000 Philips
head screw left over with no obvious hole.

powerful light, set at a low angle to create good shadows.

||You can implement every single good idea, be as careful as is
humanly possible, and you will still arrive at the completion of your
task with a missing or misfit part, and yet another excellent idea to
prevent the problem next time.
||A millennia hence, when all technical doo-dads are molded or
stamped or photoforged in a single piece, some half-baker will hit
upon the novel idea of attaching two doo-dads together with tiny
screws. This repetition of ideas generates an eternal continuity which
forms the basis of Noether's theorem.
||Um, yeah, thats what I meant. Exactly. Right.
||It's that wag, on the production line, very lightly gluing an extra screw in a place, that is sure to be knocked on disassembly. The guy that takes it too far uses a screw being 5 mm longer than the ones used in assembly.
||I posted a link, that is similar, but if you read the
description it says * Will fit both mens and
womens heads*... pretty halfbaked here at

step in the right direction. I like to highlight the

Sharpies around for this, but dont use them on or

||Perhaps it's for people of any gender identification get their
heads screwed on right?
||What a great example for significance of context in a
sentence! I was a few pages deep into reading wikipedia
about the history of assigning gender to various kinds of
fasteners (sex bolts! roooowr) before I noticed this was
talking about lacrosse rackets.
||I really like the idea. I'd love for someone who often dis-
and reassembles small electronics to have a few sticks of
different colored marking crayon to dab on the backplate
before unscrewing things. It's an interesting technological
challenge to make a pen that dabs in a different color every
time you use it. (Could just be a rainbow colored lead, now
that I'm thinking about it.)
||[jutta] thanks.The biggest issue for me is that even the "fine
point" Sharpies I use now are a bit big for some of the tiny
openings I want to outline.
||Not quite as good as a pen but useful could be a marking
laser in pen form that puts a tiny "all one color"
diffraction grating on the screw head with laser
engraving, you just tap it on the screw, and the screw
gets color engraved. Nonconductive, easy to see, and
every screw can be a different diffraction grating color.
||Actually, as an art pen, one that can draw continuously at
human velocities and do diffraction grating markings on
polymer, metal, or other material writing substrate could
||[beanangel], your laser proposal seem impractical for a few
reasons. It would have to be strong enough to etch metal and
plastic quickly enough that it doesn't slow down a technician's
work, and precisely controllable as a hand tool so as to not
damage the adjacent parts.
||I just figured the computer vision system would do that:
take a still, then image-recognize the parts, having
identified a screwhead-top only laser etch the screwhead
even if the pen or screwhead changes position; The
camera in the handheld laser engraver can also recognize
tissue and turn off instantly.
||I just think it can be strong and quick. It does not need to
be strong to do a diffraction grating depth: laser etched
mylar fun stickers have like, imaginably, 1-40
micrometers of aluminization etched off.

described, the Screw You Pen* should be no larger
