Scan thru diffraction grating challange

[dave]

A bit of work done today. Mounting hardware to hold a RC-servo in the right position to move a diffraction grating in and out of the scanners. Pretty happy with the results. More pix after i finish the projectors

How are you controlling the servo?

How are you controlling the servo?

Via DMX via this little board I designed up a year or two ago with the intention of using it for gratings.. Ha, its only taken me a little bit to put it into use..

Hi Dave

Nice set up.
I think I gone a need two of those circuits.

BTW what grating are you using?

Cheers,
Ed

No worries man, shoot me a PM and Ill sort you out a better price like before.

The grating that's in it is a bit from dragon lasers, I'm still looking for a better piece with a aperture that covers the full piece

Any video or pictures of it in action? It sounds like it would have an awesome effect but I have personally never seen it.

Very cool.... I remember Laser Fantasy projectors having quite a few pass thorugh effects that would drop down into the path of the projection depending on what was selected on the console. You don't see to much of this anymore!
Its a way to add a whole new dimention to the display when the mood cals for it...

Very well done! I have to get to work on somehting similar
