Is the schematic correct? Looking at LM324 and LM358A it seems one of these are missing? (I might just be reading it wrong)

Thanks a lot. I will try out the simulation soft and build this driver sometime in the near future :-)

Thanks a lot :-) If that schematic had a TTL it would have been perfect, I really need that for blanking the lasers. By any chance you have a schematic with TTL lying around?

Ill try to find a schematic for an op-amp driver :-) I know that I can set the max current with R4, but I wanted a dynamic solution that can be modded when swapping to different lasers without having to change resistor values etc. Thanks for your post.

How do you suggest the current increases? Its a constant current driver. The voltage goes up as the lasers heat up, but the current stays the same.

I didnt get it to work on a breadboard. Im not good with these things without a schematic hehe. Its more of a nice to have than a need to have thing, so for now, and at least till i start using a different driver I will just live without it. Thanks for your replys though. //Think ill play with...

Nice treasure chest you got there :bowdown:

HIMNL9 - Thanks a lot for that very thorough post! I actually think you tought me something :-) I will try one or more of your suggestions when I come home from work later today. //If possible I would very much like to see the schematic you have in your album. Im not set on a specific driver...

I am soo confused, with my skills I am just not capable of making this. Does anyone know of a good driver schematic with ttl and two pots - one for max current and another for adjusting between 0 and max?

Thanks, I can see what you mean and will try that to see if it works :-)

Apparently yes, however I havent got the time to do that so will seek an answer elsewhere, maybe in an electronics forum. I really need the TTL thats why that dimmer wont do me any good. Thought this was trivial for those who know electronics, but I guess not. Oh well...

Diode life over 50000 hours and for others he states over 100000 hours...

Have you guys seen their specs :-) They seem to last forever... >50000 hours

Thx for your reply. A pot would have to be connected otherwise than the resistor that is trimmed, and with my current knowledge of these things it is not something I can do myself, hence this post. And I want the max current trim pot implemented in the schematic I posted since I already have 3...

Hi all. As the title sais I hope someone will be able to help me modify a driver schematic originally created by Karol (aka C4R0 - ..:: c4r0 homepage ::..) Unfortunately my own electronics knowledge only let me make stuff from schematics, measuring and those sort of things. I am not able to...

Since the greens housing ended at the pins, its just an Aizix backend set a few millimeters in the back end of the bracket to make sure the wires soldered to the pins cant move and break off :-) Its a 100mW? from Pickegg.com. Its running at 320ma and compared to my old 50mW green it is very...

Will try that, thanks :-)

There we go :wave:

UPDATE! After some testing last night I discovered that the brackets align the lasers perfectly!! The reason my preliminary test showed otherwise was the Aixiz housings. The focus part of the housing is not a tight fit, which means that the focussing part can move slightly up or down. This...

Thanks for your replies guys. I think the solution will be to add a bigger heatsink for the mosfets instead of dropping the voltage with diodes. Regards Nicki
