it should come with a knob.

math -
4v - 3.3 = .7v / 20ma = 35ohms.
r = 35ohms / 5 (number of leds)
r = 7 ohms per led.

p = v x i
p = 3.3 x 20ma = .066w or .07mW; compare - 1/4w = 250mw

everything looks good over here, good luck building!

the difference is pretty negliable anyway, it shouldn't make a real differnce. so yeah go for it.

math -
4v - 3.3 = .7v / 20ma = 35ohms.
r = 35ohms / 6 (number of leds)
r = 5.8 ohms per led ~6ohms

so i can still use the 35.7 resistors i have now?
do you have any ideas for a housing for it? i dont have a canopy, i've heard of using half of a pvc pipe. is there anything else that will look good?

35ohms should be alright.

i have built a couple with a 1 x 1, where i counterbore a hole for each led, having the widest point of the hole house the led, then ran the wires through to the other side. it doesn't look that great but i have always had a canopy to hide it in.

If you have a stiplight you could mod it to get the led's in it.. hide the wiring up inside it with the rest of its wiring.. you would have to take it apart and figure out were you would like to put them and drill and such but you could pretty much hide them that way.. just a though..

well usually they come with a washer and nut, you just drill a hole, slide the pot into it, then use the washer and nut to secure it, and your all done.
