How to make a driver for a stepper motor
Nice job. I am going to instruct mine but Why you didn't use CD drive's own boards instead the boards of floppy drives?
Thanks for replay. Actually I have about 9 CD and DVD drive PCB's and the same number of sleds. My only problem is arrangement of the pins. Is there any refrences for the pin arrangement?

that's not boost circuit. that is laser driver to limit circuit. laser diod need a driver to not burn.
