OMG, it's like some kind of twisted alternate-history Medieval book scanner! It's full of awesome! The only thing it's missing is scrollwork!
Also... how long would it take to put that thing together?
Good luck with the talk!

Thanks, Rob! I quite like this laser aesthetic, too.
I don't know anymore how many hours of laser cutting this would take with my laser but... a few to be sure. Laser time is, unfortunately, expensive. Higher power lasers could cut this stuff in minutes.
The actual assembly is reasonably quick. Almost everything bolts together. I'd say one long afternoon for all the non-glued stuff, and one more afternoon for the platen (the glass is laser-etched and epoxied to the epoxied-together wood frame, takes time to dry/fit). So far the entire thing fits on a 4x8' piece of maple ply: $9 at Home Depot.
There are still the electronics to be dealt with, which would add a little time but could easily be produced en masse.

Hmmm... maybe I should engrave
this image on it somewhere.

this is going to be jaw-dropping! A medieval machinery, like a trebuchet, or a steampunk AT-AT walker.
I like the 80 holes matrix idea. It's the woodden equivalent of Carver Meade's "waste transistors!".
I.e. there might be a smarter positioning for the holes, but just make a lot of them, we'll find the proper way to use them.

Exactly! I was doing all kinds of careful, time-consuming measurement... and then I realized I could just build in slop to the system at essentially no cost.
These camera plates are another example. I just gave myself room for error with indicator markers. In the final version, I'll lock in the correct measurements.
Back to the workshop... gotta keep moving.

I'm definitely getting a Steampunk vibe from these pictures. Burning some Victorian gingerbread filigree patterns on the device might be indicated.

Thanks, all. I see where you guys are coming from, but
to me, this isn't steampunk. Not that we need another $punk, but I think of this as... laser-punk, if it's anything at all.
I like the "steampunk AT-AT walker" idea...
something like a militarized, rapid-protoyping NASA artifact... heh.
Two whole nights on the lighting system and it's still incomplete, but approaching completeness. Teaser with the LEDs laying in the platen:

Wowzers! I love the huge toroidal transformer! I'll bet your workshop smells like a nice campfire when your laser cutter is working on those pieces...
Along the Medieval line, you could also inscribe "Formam Transmutare Divinus" (Format shifting is divine!)

HA! Yes! I'll put it on there in
OCR-A
I've done so much lasering lately that pretty much everything I own smells like a campfire... my fingers are yellow from the burnt glue residue.
