Hi there Guys, I have a project that i like to do , i kinda have a clue ..
but i need help in understanding how it works ,
i,m trying to find a power supply for a 800 or 500 led
that i want to make i believe it going to be in parallel
this is the spec for the led

5mm (T1-3/4) LED. Transparent, Non diffused case. 660nM, 690mCd Min. output. Max forward current 20mA continuous. Max Forward Drop: 2.0V, Max reverse Voltage =5VDC.
1" leads

and the next is find the right resistors , does all the led need a resistor parallel?

thanks for your help ..
just plug your numbers into here:

if you need a power supply, get a computer PSU
Hi all, I'm working on some LED projects thanks to all the great instructables found here. One i'm working on now is a simple sign. But i'm wondering about the design and colors. Can anyone recommend software to help me visualize my design? Or do i just need to use photoshop or something like it.
Although Irfanview is a little more basic, I have used it also along with Gimp for quick changes.
GIMP works well, and it's free.
Google sketchup is pretty useful, it's free too. You can find it here
