Thank you Mccarrot. My english is a lot better then my german
Try to use simple words with the translation because then more hobbyists will understand the safety and necessary of it. Come on people be safe and buy this great device!!!

Hey guys ! as Gento says, look on the bottom of this page ! http://www.laser-safety.de/

thanks for organizing this. Now I'm on the lookout for a proper lens for divergence.

If you know what power lens you want (in diopters) let me know and I may be able to help... PM me

I did say early on I would take 3 of these but no LCD for me

thanks

Is it the Image (one protected zone) or the Magic (two protected zones) version of the board?

Did the settings remains into a memory once programmed, so we can adjust the horizon once and it will always stay the same until readjusted?

Safety USB = two protected zones

Dipswitch XX Off = All area is Safe
Dipswitch XX Off = Last transfer Data remain valid

i dont understand the purpose of this device, could someone please explain?

RTFM

Basic operation
The safety supervises the motion of the laserbeam to detect conditions which might be harmfull to the human eye due to a too slow speed of the beam movement. This includes
● static beams
● beam movements below a certain speed.
If such a condition occurs, the safety blankes the laser out to avoid damage to the eyes of the beholders.
In order to allow the safety to detect such a harmfull situation, an area called 'Safety Zone' has to be defined within which slow or standing beams are considered to be dangerous and thus the laser need to be temporarily shut off
(blanked). If such a condition is detected, the circuit closes all 6 color channels,

Since μC based devices need to be expected to fail too, the μC of the safety is supervised by a watchdog which blanks the laser out within a time of 0.01 seconds, in case the watchdog detects a failure of the safety.

Dip 1: safety time adjustment fine (2-20 msec)
Dip 2: Safety time adjustment big (2-20msec)
Dip 3: The movement factor You can choose between 1 / 2%
Dip 4: Operating Mode: Safety starts with old stored values or
Safety starts with everything in the safety area
Dip 5: Safety is active or is in the adjustment mode.

When the safety is active the LCD shows the current parameters
