dc power supply question
I have been trying to make my green 5mW DX lasermodule to work by outern power source so I wouldn´t need batteries.
I have this regulated dc power supply 2000mAh.
I broked one module because something heated up very fast in its driver while power supply was in...
i saw same kind of question with a photo few pages back, but this meter has a slight difference to that other i think.
so i want to be sure how to measure mA with this.
should i put black to the COM, red to the red circle place ofcourse. turn the pot to Vac 200?
maybe many, many times asked question.
i have a 5mW new wish green.
if i want to make yellow, i need 20mW red. is that correct?
then if i add a 10mW bluray, do i get "whiteish"?
am i at least near right?
i like to stay in quite low power range..
and where do i get 20mW red because all i see...
Questions from a new member:
Can I make a 5mw bluray pointer or is it always like 10mw and more?
I´m not interested burning stuff, I just want to make quite "safe" laser for a first diy project and use it indoors to make little effects.
Will it work if I buy a ps3 kes-400 from...
