Foulmist, i can`t find a SMD resistor of ~0.15ohm here.

What`s the calculation of the resistor? I think i can find a 1ohm smd but i don`t know how to calculate the output current...

you can find smd resistors in farnell or digikey or other electronics webstore.

the current is calculated I = 0.25 / R for the dx driver I referred to.

you can stack some smds on top of each other in parallel if you can't find the exact value you are looking for..

here is a great resistor calculator in parallel

SMD resistors with low ohms are slightly hard to find here too. They only send them in quantities of 100 and the price is $10, so not that cheap considering you only need one.

I have two spare 1206 0.15 Ohm resistors, so if you're having trouble finding them, PM me.

Cheers!

First thing i think was worth studying at school: 1/R1 + 1/R2 = 1/Req

THanks for the offer ryan, i'll search local stores tomorrow and if i don't find it i guess i'll have to ask you for one!
