wiring led to 110 power supply Answered

new to this whole electronics thing, have a basic understanding but still a little iffy on some stuff. i seen the glowing cube and thought it was sweet. so my plan is th make a wall picture. take a 24 by 24 by 1/2 plate of plexi and drill holes into the side for the light. so basically what i'm asking is what size of resistor and how many would i need to hook up to a 110 supply so i can plug into wall

search for led here on ibles...theres tonnes

There are 2 options - to use a transformer (safer) to convert the 110 ac line voltage to a reasonable dc voltage, or hook up the leds in a rectifier setup with sufficient leds in series to drop the high voltage...

Use http://led.linear1.org/1led.wiz to calculate the series resistor.
