I had a saber that was driven by a buckpuck, powered by a 7.2v NiMH pack. For some strange reason, the last time I charged the batteries via charge port, the buckpuck burned out. (And the charger does have a DC converter in it)
Any idea what went wrong?
And, this one's got me in a real funk: as a temporary thing, I was going to drive my blue P4 on 2 AA batteries (2x Single AA batteries wired in series), well below the minimum voltage, direct drive style, no resistor.
The LED didn't light, at all. Once I put the LED back into it's saber, it didn't light there, either. So, I burned out my LED with less than the forward voltage.
Can someone please tell me what happened here?
