Hello, I have made a schematic on eagle and i will finish the pcb in some hours !

I will offer this driver on a pcb pre-soldered or as a kit

Price list :

DDL Driver kit: 8$

DDL Driver parts soldered: 10$

The parts are(LM317,POTENTIOMETER,RESISTORS,DIODE,CAPACITOR)

Also you will tell me the current that you want so that i can find the correct value for the resistors !

I want to find out how many people are interested and then i will order the pcbs !
 





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.

We would need pics of what you want to sell...
And shipping cost from Greece...

I cant send you pics of the board yet ! But i will soon ! Shipping would be about 3-4$ worldwide. If i post the schematic and the board could you tell me if i have any mistakes ?pls
 
Mabye but why not just have the better chip. also we have the jib driver groove2 and rckstar microdrive . So you have a lot of compatituon bud. the jib drivers are $9 shipped for lower powers
 
Yes but this driver has i wide variety of current ranges from 0-1500mA !And also has reverse polarity protection and prevents voltage spikes !
 
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.

wouldnt a lm117 be better that way you could use it for 2 cell blues

For 2-cell blues, LED buck drivers are the way to go. :beer:

Voltage spikes won't hurt a diode.... Current on the other hand

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.

ahh i apologize i shall edit my post and led buck drivers are a pain in the ass to wait 3 weeks for
