Laser boxes inside laser printers? What to do with them?

Hi folks, I got a whole bunch of these laser boxes--separate units from inside these laser printers I'm still not finished disassembling--they seem so important...cool stuff inside...what do you do with them? (In terms of making money off of em?) I don't see anything like it on eBay so...

Suggestions? Advice?

So making one ty for sharing

dang! i was gonna pop off about making a laser light show, but didn't wanna be a smart but! maybe it is possible huh ? watch your eyes while i turn this thing on ; )

call me paranoid but i would get some lead underwear too!

its just lasers and motors with mirrors nothing radioactive about it.

if you don't see one on ebay you can guess it's either not in demand, or, you've got the only one in the world, lol I sometimes listed things one at a time, as if it was the only one around

I just listed them as the wrong thing...they are just listed as laser scanners...i was looking for laser boxes...and oh...a bunch of other silly names i made up for them that didn't work. Anyway...they are not radio active unless they are ON...and even then...it ain't much...but, as the box warns...do not look directly into the BEAM!!!

Anyway...they are cool.

found 30 lbs of lead weights in an alley today...that was cool.
and a bosch dc window controller motor too...nice.

nite.

bosch makes good stuff

Dose anybody buy these laser scanners, I have a box of them,or should I take the boards off and throw the rest away? Thanks for any advice.
