I got an idea for my spare 3.25 bay and i also needed a place to mount my cathode switch.......WAT I NEED TO KNOW IS: if this wiring job will work...do i need reisistor(if so explain), and if my model wont work can some one draw me up one that will. here is the front view of wat i wanna do and here is the wireing ne opinions or help or ideas?
i dont think putting 12v through those leds is such a good idea but then again i dont know much about electronics. also....wouldnt running them in series make each consecutive led dimmer than the one before ?
That's quite wrong, I'll draw up a schematic. I based the resistor values off the assumption that hte led forward voltages are 3.3v each. Tell me the real value and I'll work it out for you if you need help Your image is wrong due to the following: LED polarity are wrong, longer leg is the anode You are trying to wire the leds in series with the inverter, thus pulling all the current through them (lol) No resistors Its basically quite wrong If you want I can get you one of those, and it allows you to connect 5 switches and 5 leds (one led per switch to note that the switch is on/off) and ofcourse 5 devices. You can either have it in 2 configs. switch 1/2 are 12v and 3 -4 are 5v or all switches 12v. Let me know if your interested! Just as an explanation how you would use it: Connect to the 4 pins header 12v from PSU to pin 1 and 4, 2/3 to ground. As for the resistors you need to calculate based on your leds. The rest is simple!
Haha your not meant to, its an etched PCB and the traces were arranged by the auto router. Just connect what I said to where and it will work! (I made it and I'm using it in my Mithril P4 Casemod)
bsodmike how much would it be for one of those PCB's? Could I connect would wiring LEDs of it be just like taking them of a molex?
sickskater6911, sorry to hi-jack. one PCB = gbp10 inc posting..fair considering it cost quite a bit! if I include the components - gbp15 inc posting.... I used 'jumper header plugs' so its much easier than a molex even!!
