Oh ok, sorry for the inconvenience
Oh ok, sorry for the inconvenience
OK! so I did my calculations for my resistors and i just want to make sure Iam in the correct ballpark. For my illuminated AV switch I got a 39ohm 1/8 W, for my green die in the CREE tri xp e2 I have a 1ohm 1/4w for the red I have a 3.3ohm 1 w and for the royal blue I have a 1 ohm 1/4 w resistor. Does all this sound right or did I not plug in the right info? One more qustion, do I need a cex for a prizm?

No inconvenience at all! welcome to the forums! Iam new here myself!Originally Posted by Yugi

It's not really an inconvenience, but what you're asking about is going to be totally different than what Jake is doing, and so you'd be better served with your own topic for the Parks saber.
Got a question? Start Here. Have you tried the Thread Index yet? Most questions can be answered there.
You do not need a CeX for the Prizm.
The numbers for your RGrB LED don't look right. Could you post your calculations?
You could use the DynaOhm resistor for your switch LED. It has to be wired right to work right, though. The in or + side is wired to the battery/recharge port, and the out or - side is wired to the LED. Also, the DynaOhm must go onto the positive wire to the LED.
I plugged in my battery voltage (3.7v) and the info provided by tcss for the triple Cree (RGrB) into the led resistor calculator . I also thought about doing the dynaohm so thanks for that answer!

Ohm's Law: Resistor = (battery voltage - LED forward voltage) / current
So if you want to run a green Cree LED at a current of 1000 mA (that's 1 Amp), you will need the forward voltage for the LED (found on the store page), and your battery voltage (in this case 3.7 volts).
That gives us: Resistor = ( 3.7 - 3.58 ) / 1
So: Resistor = 0.12 Ohm resistor
For wattage: Watts = Resistor x current sqared
We have: Watts = 0.12 x 1 sqared
Or: 0.12 Watt resistor
Round up the Ohm value to the nearest resistor. The higher the wattage, the more energy the resistor can dissipate, so round up the Watt value also.
So a 0.12 Ohm 0.12 Watt resistor gets rounded up to a 0.47 Ohm 0.5 Watt resistor.
EDIT: I think I just learned how to do smiley faces. Well, one of them anyway.

Well...Hi I'm new to the forum, I purchased a graflex kit from park sabers. Can anyone provide me a list of parts that I need to purchase in order to convert the hilt into a working saber with a blue blade, sound, and maybe flash on clash. I would greatly appreciate it
Basically that. Welcome to the forum.
You're more likely to find the help you need if you have a thread that is specific to your needs, plus it won't put stuff into Jake's thread that isn't relevant to him. Make sense?

Thanks! I was a bit lost because I couldn't find the resistors I was looking for......at all.....hahaha. Congrats on the smiley faces, I am still honing that skill myselfOhm's Law: Resistor = (battery voltage - LED forward voltage) / current
