I will be there tues 7pm-ish

The lighting kit and cams (canon powershot elph 160) just arrived with the lighting plate cut for the archivist. Photo attached.
My mistake on getting the cart before the horse. I did not know diybookscanner was sending me this plate.
Maybe we will be able to just cut that plate down. Let's look at it.

I think the order of tasks needs to be something like.
1. Obtain bolts fitted to tripod mount to mount cameras
2. Mount cameras with a temporary spacer representing an adjustable plate
(plate needed for: 1. power attaches on bottom of cam . 2. Cam needs to be adjustable in fine increments)
3. using archivist plate as a temporary, find the optimum lighting distance
4. create new structure to hold lighting plate
5. design new lighting plate if necessary from DXF or SVG file provided

We need to create more distance between the lights and the glass platen. The hacker-space design was defective in that. It was suggested doing this by eye is best

I just requested the DXF. I asked for the SVG also. I will email as soon as
I see the file. I will confirm Tuesday 7p if it comes in before then.

Jake if you could bring in or drop off that circuited FR4 which sounds like
it should work, tuesday may be possible.

i can swing by tomorrow 7pm to run machine if you'll have materials

Thanks hol.

Does the SUDO have a machine to cut FR4 from a file? To do that, should I
ask for a DXF or SVG file or something else? This is outside of my ken. Can
someone else decide that and email me so I can ask for the file - and cut
this little piece this week? I can help.

Lighting assembly parts and cameras supposed to arrive today.

i know printing a dxf as an .xps document works if you have CAD

Which format?

I don't know anything about the machinery available at SUDO room or these
kind of file formats.

looks like it can hit 2 dimensions uniformly

Just looked at the instructions - are we overthinking how to
illuminate a piece of paper?  Could easily use an aluminum channel with
white LED strip to do same task.  Happy to bring these materials next tues.

probably less than a square foot or half of that. depends on how we
remake the piece holding the light to raise it higher

i have plenty of FR4 that does have copper on it, we could still use
it for
this.  how much do we need?

Nice! I'm not sure we have any non-circuitboard FR4. If it's not too
big we
could just order it from e.g. seeedfusion as a circuitboard design
with no
exposed copper pads.

I just purchased two refurbished 20 megapixel Canon PowerShot ELPH
160 and
the archivist lighting assembly which includes LED bulbs, sockets,
lenses,
wiring and power adapter.

Jonathon will send us the design files for the sockets mounting
plate soon
as I tell him what format we need to cut it at the SUDO room: DXF
or SVG or
something else?

This is the page describing the plate. It would be convenient if
the SUDO
room has some FR4 but as long as the material is opaque, heat proof
and can
be painted black, should be no problem.

This plate will sit at the top center of the scanner. The plate also
serves to block light from entering from the top direction. Since,
we need
to attach something to raise the lights higher than the original
hackerspace design, we should not cut this out yet. It does not
need to be
the same shape as the archivist plate as long as the socket
mounting holes
are the same.

Jonathon wrote last week:
."..you can move the lights further away from the platen. Because of
various design constraints, Daniel put the lights closer to the
platen than
is ideal on that model. For later models (like Daniel's Archivist
design),
the lights were been moved further away to reduce glare and hot
spots. You
want to reproduce this in some way. So just build a simple frame
you can
set on top of the scanner to lift the lights. There is a
mathematical way
to find the minimum distance, but it might be easiest just to do it
empirically, pulling the lights away and taking sample photos until
you see
that there is no reflected light source."

You can see how this the lights are put together on the archivist
about
halfway down this page
