Galvo Lasers

Hi Brian:

I hadnt posted it yet. It is attached to this post though. Let me know if you have
any trouble with it, I cant recall if I modified any system libraries as tweaks to make it
work faster.

  I havent cleaned it up and documented it yet, so its a bit messy.. :)

Hi :

The following zip contains a new winterrupts.c required for compiling the code in the previous post.
Also a wiring list for the arduino is included.

Hi:

  This is a post for archival purposes. I discussed earlier in this thread the posability of using an arduino
to better control my lasers power for photos. I did make on from an arduino Due and an LCDShield 2.0,
in which a pwm is fed from Auggie ( or whatever) into the arduino, and a selected scale factor is applied
and sent out another pin.
  This means at default power on operation it is set to 100% and simply passes pwm through itself,
however it can be set from 5% to 100% and will scale incoming PWM commands from 0-100% to
100 levels of selected scale power. This allows software limited to 100 slices of power, to have 100
slices of power at any set level by the time it reaches the laser.

  I include a photo of the device and the .iso file for the arduino to make one. Its hard to say if
this is usefull for anything other than  laser driven by auggie, Im not sure what the granularity
is of other lasesr when set to lower power. If a laser set to 20% simply allows power to be
20 levels instead of a 100 levels of 0 - 20%, this may be usefull to someone. I'll post it here just in case
someone in their searches is in need of a PWM scaler. :)
