We have like 600 Front surface mirrors, Anyone interested in handfulls like for use in combining reds or general projector internal beam stearing mirrors?
Thinking like 4 euros each + whatever shipping and packging would cost.
minimum 10 units as they are tiny and not worth the packaging.
Also
Will have some defraction gratings with rotors aswell like 100 units, gratings are mounted inside a rotating shaft so you just need to add them direct into a multi colour beam up-to 7mm OD and connect 5V to the geared motor. Mounting is extreamly simple.
Will be including two gratings with each motor with instructions how to make some cool effects using both gratings.
Thinking like
25 euros each for up to 10 sets
20 euros each for up to 20 sets
15 euros each for up to 30 sets

The gratings are good quality Glass, not thin cheap plastic.

Full rotation is ~9 seconds at 5V, can be slower with some small transistor; likely can be faster too with a small voltage increase.
Grating effect are grids of dots for the first grating then when combined with the second grating its thousands of dots all moving is around like a pair of expensive Machado star gratings.
It’s good enough that we used these in our lasers with small actuators to introduce the first beam then the second grating on the end of a solenoid to give different effects.
A video is here: http://www.youtube.com/watch?v=zxgsxxyOXqY at 4:04 10 seconds of it sadly you can't see the grating effect so great due the other beams that got in the way. Information on the show, it is the day of the Man in Romania which also corresponds to a beer festival where there are live music followed by a short firework and lasers show. The music is By one of he best known Romanian bands call Iris.
Also with both gratings in the beam, varying the 5V also produces variation of effects, I am thinking to put a small DMX to RC servo receiver to do this control. This way would require 3 dmx channels, on/off motor speed and second grating on/off. doing it this way is a bit more complex but for simple hobby applications a direct 5V to the motor would be ok. Maybe somebody can suggest a small speed control for the DC motor and little Solenoids to active the beam and second grating.
