[BIETE] Diffraction grating geared 5V DC motors and gratings

[andyf97]

Diffraction grating geared 5V DC motor with a free flywheel mounted star burst grating.

Just add 5V DC and have a wonderful star burst effect, the grating can also be pushed out if you want to replace it with another.

I have also a second grating that can be supplied to make a very mixed effect as can be seen in the last two videos.

The gratings are transmissive glass.

Prices
Rotor with mounting plate and glass grating as in the photos costs 25 US dollars or 19 euro each.
Additional glass gratings are 5 US dollars or 4 euro each when purchased along with the rotor.

Shipping is included for two sets at the slowest cheapest possible cost, or I can send by DHL with tracking.

If you want more than two sets please request price in a PM.

Discount available for 10 or more units. ( 230 units in stock as of 5th December 2012 ) 43 sold.

Bellow, videos and photos with a 445nm diode running around 1W thru the grating.

Is the price too much?

Hey.
Your Price is good, but nobody here knows anything about you.
You should write something more about you.the most user here are doubtful if there's a new member and one of the first threads is selling-thread.
Perhaps a few members here know you from the PL.But there you have not the best reputation.

Ahh, good point, something that I never thought of. You are right.

Happy new year and thanks for pointing that out.

I cannot edit the original post now which is a shame, so I will give a link here to my other page on photonlexicon where quite a lot of feedback is visible.
