How much for the bounty?

waiting eagerly your results Mickael

You have to eat some chocolate and coconuts..... and wait for a night ( based on a French joke) :-)

OK, I finally found time to test the scanner set. As I'm not a expert, I just posting the pictures and you have to comment. Ask me for more tests if you want.

The setup is : Beyond, flexmod N2 with a 50mw green diode, and EMS 5100. it's a very easy setup (I'm sorry for the poor wiring).

Pango software and Eye-Magic scanners...


Seriously talking, did you measure the scanners aperture angle?
Ground signal is not needed in this setup? (I only see a 2-pin connectors input for scanners signal)


Regarding the test frames, they have sharp corners. However, the circle in the second test frame is strange... I guess that if you change the "blanking delay" from 5 to 3 or 4 in Beyond setup, the result should be improved (as it is not a DPSS but a direct diode with faster reactivity).

For the soft i ´m doing with what i own...nobody ´s perfect

Yes,Ground signal is not needed as there is only 2 connectors.
In fact sbk send me the link for the ems 4000 as there is no paper with the scanners.
For the blanking delay, i agree with you i must adjust it.
I must check the aperture of the scanners, but as i was at 50% size in beyond, i can compare with other models.
For me the only gain is the space, i.m not convinced by the speed (i must check another time). No real problem as Tom describe them like that.

Nice to see that you sorted out the wiring. I agree Eyemagic should at least send a link to a proper datasheet, fortunately they use always the same colors for the same signals on all their stuffs...

If it's similar to EMS-4000 then 50% of the full angle should be around 27° from factory adjustment. And yes I don't think they will be useful for intensive graphics use, but would rather be reliable, small footprint, precise, easy to install and inexpensive scanners for beam shows.

If you want small and capable try the 506 scanners. They no $h|t blew me away.

Mike, I think they are over speed at 8 degrees, or scanning at too wide an angle if 20k at wider.

I'm certainly not seeing the square corners your reporting in every pattern. Only the grid is rounding but the sides aren't square even when the actual peak of the corner is sharp.

Pattern by pattern:

Sides bowed inwards on "Top" pattern

Sides Bowed and Circle Destroyed and inside the square in the ILDA 30K Test pattern (can't see the rest clearly enough to analyse in detail) but the circle indicates the scan speed is too fast for the angle

Sides bowed and Double Lining in the Diamond Pattern (again speed / angle indication)

Grid Pattern, rounded corners (speed) and "holes" in 2 of the corners

Circles Pattern (colour test but obviously mono laser), bowed sides

I think KL you need to measure the angle as they aren't making ILDA 20K at the current angle at present (then at least you know what you're making at the moment). Then I'd reduce the angle to 8 degrees (using some simple trig is easier than trying to hold a paper angle pattern up to the laser) and then reduce the speed until the ILDA 30K pattern is perfect.

The perfect ILDA Test pattern and some explanation can be found here:

This is an Eyemagic thread mate. Please stay away with these damned Pangolin scanners, even if I do know they perform very well, I believe we had enough drama about this these last times...

Oh dude facts are friendly. Either the scanners have what it takes are they don't. The simple fact is the is a spectacularly bad test by someone who shouldn't be running tests in the first place. This thread is a complete waste of time.
