DX red/green star field show

I just wanted to share with everyone this: http://www.dealextreme.com/details.dx/sku.14651

It looks pretty interesting, for a good price two! I wonder what all involves.

looks like 2 spinning diffraction gratings

Yeah, they have a new laser for DJ's that gives an effect like that. Its basically just 2 spinning diffraction gratings and a red/green laser. Very simple ..

Well thats pretty cheap for 2 diffractions, ac-dc converter, 532nm & 650nm lasers (granted, they're only 5mW but perfect for this application) motor, plastic box.

Exactly the reason I refuse to pay $70 for something like that.

Its cheaper to build you own one of these.

It'd be good to put a bigger green and a bigger red in their, maybe 50mW of green and 100-150mw of red

2 fractional RPM motors and 2 defraction gratings and 2 cheap lasers. DONE
