Hey all, I'm a "beginner" when it comes to electrical designs and would like a little bit of help if someone could lend a hand.
Current Project:
Modifying a computer power supply into a portable test PSU for electrical and computer equipment (using attached molex connectors and added RCA or 'phono' exterior power connectors).
Problem:
Now in a nutshell what i would like to do is wire up the female RCA jacks to emit 12VDC (which is easy considering the PSU already puts out 12VDC 5VDC and 3.3VDC). However, as a nice effect, I would like to have an LED connected to each jack...so that when you plug in your device that needs power, the LED will power on to clue you in to the fact that there is power running through the circuit.
Now....i'm running LEDs that require a min. of 3VDC and a max of 4.5VDC so I require a resistor for each Circuit that the LED is on...which cuts down the power running to the jack....crippleing whatever is on that circuit (besides the LED, that is)
Is there anyway (besides using a relay) that The LED can be hooked up to the jack in the manner that i am looking for?
Thanks in advance all.
