Please note hat the D4Drive was not designed for driving blue ray diodes but will do so with a few modifications-
1) The Vf of the blue ray diode is approx. 5V so you need to increase the
supply voltage to 7 to 9 V. Tant must be rated for this voltage.
2) The D4Drive uses the supply as a reference for setting the offset current
(and also setting the operating current when DRV linked to SET)
This means you have to use a regulated 7.5V or 9V supply and the o/p current
listed in the drive tables -
http://www.die4laser.com/dvd-rec/Die...iles/Drive.xls has to be scaled
for the new supply. 9v will give 9/5 times more current.
You can put in a new supply voltage into the spreadsheet....
