ok so i finished soldering up my first laser and the rckstar circuit board gets really warm but the diode does not light up at all. If i killed it wouldn't it at least be dim and i accidentally soldered to the bottom because i am dumb so i resolderd it on the top and i know the ground is to ground and the positive leg is to the positive spot. So as of right now i am unsure of what i did wrong do tou all think i have a fauly diode or circuit board or what. thanks.
