what is the transparent glue stuff
mowcius is correct, just plain old hot glue. I love the stuff, use it on everything. In fact, it was the key to aligning the mirrors. While it was soft, I spun the motor and centripetal force pulled the mirror into alignment. I then maintained speed until the glue cooled and hardened. The stuff is great. I suggest you also get yourself a butane micro-torch. It's always nice to be able to reheat. cr0sh:
I would go about setting up the mirror wheel in a much more complex manner
Cr0sh, I really do like the sound of your design. It would certainly offer a lot of benefits over mine. However, mine design very well met my needs. My primary concern was my severely limited attention span. To cope, I always aim for the quick and dirty solutions because anything else and I risk losing interest in the project before it is completed. cr0sh:
I also found a 12 watt TEC cooled laser module (fiber optic coupled) - I am wondering if something like that could be turned into a laser cutter, once mounted on an X/Y/Z table.
It's funny that you would go there. A previous project of mine, which I abandoned because of lose of interest
, was an Arduino controlled multi-purpose X-Y table. My plan was to have swappable heads, one being a burning/cutting laser. I finished building the table, complete with stepper motors and Arduino control, and I was in the programming phase when I put it on hold. I was considering returning to it soon.chris mitchell
I could turn up the laser in my spirograph to burn but then why?cr0sh:
Spirograph puzzle pieces? Spirograph engravings?
As awesome as that sounds, I doubt Chris's Blu-Ray laser could burn at those speeds. But increased power increases visibility. A problem with my projector is the output limits me to use in dim lighting only.
