Alright I just blew up an LED by hooking it up to a 9V battery without a resistor. So I've got a quick question, can I hook up a resistor on the cathode side of the LED like this: Or does it have to be on the anode side? I'd try it out but I don't have any more LEDs I can sacrifice.

Thanks for the answers, for the curious I was building this PC fan controller: http://www.cpemma.co.uk/sdiodes.html As I understand it, this thing uses diodes to make voltage drops from the +12v rail of the psu, which in turn controls the voltage that the fan actually receives. My question is, why can't we use resistors or even a potentiometer to achieve the same effect?

Anyone have experience with rework stations? In particular, I'm looking to buy this one: http://circuitspecialists.com/prod.itml/icOid/9766 I'm not too sure how interchangeable this station is with other tips/nozzles, and I haven't been able to find many reviews on the net about any rework stations at all.

Thanks for the feedback on the rework station guys. I guess for now I'll be going with the CSI-STATION1A as my iron. It's a knockoff of a Hakko 936, so it seems it'll do for the small hobbyist electronics work I'll be doing. That, and I can't seem to find a middle ground between the Hakko936/Weller WES51 range to a Metcal. Do you guys have any suggestions on which hot air stations to look at?
