Most people who are interested in DDL/LM317 drivers can get the parts and make it themselves. I don't think many people would be interested in this, though it's a good idea.

Yes but this driver has i wide variety of current ranges from 0-1500mA !And also has reverse polarity protection and prevents voltage spikes !

Default Re: Feeler: Ddl driver pcb

I'm sorry but a LM1117 driver is simply better, and it's already available at a very cheap price. You don't need reverse voltage protection as long as you're careful, and if you did, it's easy to add a diode to Jib's driver. If I were you and wanted professional, I would just order some PCB supplies and make them for myself. It's not that hard of a process, and you get more of that "DIY" pride. I made my own LM1117 drivers, about $20 for 50 driver's worth of parts. I made 10 drivers in less than two hours, that are even smaller than Jib's. (Those were just on perfboard, but I have made my own PCB boards before, and it's not too difficult.)

Edit: Best of luck though, with whatever option you pursue.

I'm afraid you're mistaken, sir. Static discharge is one of the biggest killers of laser diodes, yet the current of a static shock is a few mA at most.
