I don't have a watch and have some time on my hands..( lol funny?)
I was thinking of placing of stripping this down and placing two led's in back and having a watch inside the pc..

anyways i really think it would look nice in the place i picked out for it.. i need some help finding out how much resistance i need to put on it so it won't blow..

A 1.5V battery cell powers it, and i have very little experience with voltage and oms. help.

if its only 1.5 volts yolu should hook it up to the hard drive activity light so it only displays time while your hard drives going

Wouldn't that reset the clock everytime the light goes off.

wait a second, the clock will reset everytime i restart pc.. this is a bad idea.. =( damn it!! i want to make this mod so bad cause i had some small spare leds to place behind the clock.

Why not just leave it battery powered?

You have to figure out the reisistance of the clock. Do you have a multimeter to measure it with. If you did just measure it and I will tell you the resistance you need.

You will want a resistor that is 7/3 times the resistance of the resistance fo the clock.

i have multimeter but don't laugh i am complete n00b at using this.. i want to learn but not enough time on my hands....
Its bad idea, because i want to have Led lights in the back of it...

All you have to do is measure the ohm across all the leds and the ohms across the power terminals of the clock. If you give me those numbers I will give you a diagram on how you should wire it up.

Run the clock on batteries and the LED's from a 5v line (with resisitors of course).

fine u guys are pressing on so the mod will continue.. i know the resistors to use for the LEDs, i am gonna open it up carefully in the morning and post the pictures.

anyone know how to make Leds reflect best off the lcd?

Dont modern ATX PSUs have a 5v standby power that is on all the time? So it would only go off when you unplug your computer?

Either way i would go with LED computer powered only and leave the battery.

I use this to calculate resistor values needed.

As for lighting the LCD? Unless you can light it from behind/side I doubt you will get anything that you will be able to see clearly.

try finding the 5 volt standby thing if it exists...if not then leave it battery powered or use a weird resistor adapter combo straight to the power plug to power it and the leds 24/7 if you want...

The leds wouldnt take to ac current very well. Your best bet would be to go the battery route.

Bummer. That sucks
Hate it when a plan doesn't come together.

Better luck next time.
