Okay I just ordered a whole bunch of blue 3mm LEDs and I don' t need all of them. I have 350 to sell so heres the deal: I am looking for 30 SHIPPED for 100 each or if you want them all i'll sell for 90 shipped. If you want resistors, I have a variety of them and I really don't know what each one is for. I will sell them for $.04/piece so 4 bux for 100. If you no one wants them all, the extra 50 i'll sell for 18 shipped + 2 bux for resistors. I just ordered them so I will ship them off to you guys when they get here (probably early next week). These prices will only stay for a few days.

If anyone is interested I can also sell some UV LEDs at the same price. here are the specs

BLUE LEDS
Size: 3mm
Forward Voltage: 3.5V
Reverse Voltage: 5V
Current: 20-50mA
Viewing Angle: 20
Brightness: 1500-2000 mcd

UV LEDS
Size: 5mm
Forward Voltage: 3.5V
Reverse Voltage: 5V
Current: 50-90mA
Viewing Angle: n/a
Brightness: n/a
Wavelength: 400-405

If you want resistors, I have a variety of them and I really don't know what each one is for.

When you have a battery:
CODE
- BAT +
|        |
~      <>
+-----+

~ being the resistor, <> being the led
If you don't have a resistor in the circuit, the led will burn out. A good resistance is usually 4.7kilo ohms for a resistor. Which is normally called a "pull-down" resistor. Basically, a resistor limits the Amperage in a circuit so your led doesn't get overloaded.

i thought resistors are on the positve wire?


CODE
                   
BATTERY PACK
-                     +

|                     0

-                    +
       LED

| = wire
0= resistor

or am i just screwed up?
