This may be a very stupid question, but . . .

[Mr_Lazo]

Would it be a "bad" thing if I were to switch the polarity of a ~100mW BR running on a rckstr driver from case+ to case=? If so, why?

I found a great host that, essentially, would only need the lead and ground wires pulled off of the existing board and soldered to the new driver. No other modding required -- providing, of course, that changing the circuit to case neutral won't kill my diode.

Yes, the serch button is my friend, and I have used it; however, the most I can find is a discussion of how specific arrangements are usually wired, with nothing on possible adverse effects.

for blu rays it is perfectly fine for you to switch the polarity as the case pin is neutral. you can make it either positive or negative by soldering it to either the + and - pin.

red diodes are a different story because the case pin is the negative pin.. so you wouldn't be able to.

Good answer sk8, just check that the + has not already been linked to the case pin for mechanical strength.

The case pin is still floating, at this point.

Therefore, if I leave it as such, it will be safe to swap the driver to a floating circuit (case neutral), yes?

yes

Groovy.

Thanks for your help, guys.
