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...

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...

you have a PM
