Default Re: FlexMod P3 driver circuit HOW TO BUILD

ok i did build AKA DDL circuit and im just wondering is there way to improved for different lasers 405, 445, ...... and how, im new to this but first i build works perfect with a diode from old cd-rom drive so is there any other driver circuits we all can do at home from parts?

Sorry im Russian some times spell words wrong, but im living in US so in 3 years i have some improvements on English lol.

Thanks to everybody...

one more thing, is that passable to add some thing to the circuit that you don't have to discharge the capacitor before installing the diode?

A bit late for me to reply to this, but why not... Yes, you can simply put a resistor across the capacitor leads. I would say 100k ohms or so would do fine for a decently fast discharge while not interrupting output current

Or if your running off a relatively clean stable power source like batteries, you can leave out the cap entirely.
