Hey chimo i am talking to you , like i am saying i build already the unit, i use 6 LR44 to make 9v, i adjust the trim pot til 38ma, can i adjust it to the ma you got there to light the matches? im worrying that my bluray will die after i done that, what you preferred me to do in my situation , thanks.

The LR44s voltage will sag quickly, but they may run it for a while. If you have Li-ion charhing capability, 2x 10180 Li-ions will fit in teh space of 6xLR44s. The laser was lighting matches at the upper end of the drivers range (~60mA). I did not test it in between. Remember that individual LDs will differ and the current that one will tolerate may kill another. Good Luck!

Looking at your images, I see what appears to be a blue powder on the inside surfaces of the enclosure. Copper sulfate from moisture + battery, or just plastic dust?

Just noticed this question.

It's just plastic dust.

ok thanks, what was the voltage output and ma of that 10180 LI-ions?

Well, it's a Li-ion so it's 4.2V open circuit with a 3.7V nominal rating. I don't recall the mAh rating. You can find them in the Dealer section at CPF Market Place (sold by user AW). Make sure you have a properly rated Li-ion charger before you consider these. AW sells them as well (and no, I'm not affiliated with him).
