Thanks a lot man, that's help me a lot to know if I have to put a heatsink to this driver

That's didn't work too...I get 0.00V So I will put it dustbeen and contact DX or maybe you have a better idea ? Have you got a link to a buck driver like this from Europe ? I have a LM317 laying around do you think I can use it with 2 li ion cells, I think it will not be a problem (min Vdrop =3...

Hello, I want to know how we can calculate the power dissipation of the LM317, I saw in the datasheet the ratio temperature/W, however how to calculate the power takes by the LM ? Is it something like Vin*Currentset ? (In my case it will be something like 1.25*8=10W) Is it a good idea to power...

So I made a test load with 6*1N4001 and one resistor (1ohm) (in fact it's potentiometer but we don't care) and I get...... nothing (of course I fix the bridge however there is a contact between this coil and the red wire since I with a screwdriver I saw a copper color) My test load seems working...

Thanks a lot for your reply, Ha these chineses^^, i will (try) fix it tomorrow and I will change the wires since they are too thin I hope the driver is not damage... Good night

yeah I know what you mean for the capacitor so the capacitor and the red wire shouldn't have connection ? OKay I will make a test load tomorray (i haven't enough diode right now) Thanks

hello, I had mount my laser with a housing from sinner, an M140 diode and a "18V 5W Cree Circuit Board for Flashlights" however I have a problem the diode doesn't light but the led seems to work since I powered it during 1/2 sec with one li ion cell...so that's driver in fault. (i use 2x1640 li...

up ;)

Hi guys Ah sorry I didn't know that aixiz make copper module that's why I didn't put pictures... So mine are nickel and come with everything on the blord's picture They are brand new and are not faulty; le quake is right(aixiz send me accidently 18 modules) For the price I think if I can have...

Hello, Du to an aixiz sending faulty I receive 18 of their entire nickel modules (spring, host, focus lens...) I prefer to sell the lot. Make ANY proposition(s) Thanks

Thanks a lot for your reply, I will ask to him some questions about his laser. Thanks for all your help I will answer you when I will have my laser ready

Thanks for your reply Yeah I know I didn't tell you more detail about the heathsink.... But I don't know what to do because yobresal is selling a great deal. You tell me that you have one of his kit are you satisfied with it ? does the heathsink for the diode suffisant ? isn't in copper right...

Thanks a lot for your reply, I understand now how is it important to have the correct wavelenght lens for a diode. I wasn't thinking that there is huge difference between these diode (simple to double...). So what is its nominal output ? 1W ? I think I will make my custom hostmade with copper...

Thanks (again) for your answers I understand better now... And for finish with lenses is there a big if we use a different wavelenght lens compared to a lens with the adequate wavelenght for a diode(with of course the same number of element) ? I see somewhere that the M140 diode are sell for...

Thanks that's help me a lot. WTF ? we can see on the graphe that an aixiz acrylic lens is as performed as a glass lens ? But we can't use it for high power, is that correct ? WTF(2)?we can see on the grphic that the wavelenght for glass lenses have no impact on the ouput, and a 650nm is more...
