    Can't make the diode work[help]

    Hi. I'm in need of help, I've just wasted 6 22x diodes trying to do a laser pointer. 1) When I turn on the circuit (the capacitor is discharged, the diode was connected prior to the power source) it shines great, but then it dies, turns into a dim $1 laser. I'm measuring the current and it's...
