Okay i just blew my second and last diode(or did i?) this was my finale diode and im wondering if it truly is dead i hooked it up to a dorcy mini but no light i took it out found my connections still good and tryed to test my diode for ohms and it read none but do diodes have a closed circut(as in they only complete the circuit when power is intruduced?) If it is blow im out of the DIY laser hobbie :'(
