Graflex 2.0 Sabers - Show your work / Talk Electronics

Thanks for those links, they are helping. Though now I have hit a brick wall it seems. I've been trying to figure out what resistors I need for the Tri-Rebel (blue/blue/white) from TCSS, but I can't seem to find the "diode forwarding voltage" to enter into the LED calculator to save my life.
Shoot2thrills diagram has that tricree in it
 
That'll help...the recharge port addition will help...I've ordered the 1ohm 1w resistors now...

And if I have some 3.1v LEDs for the crystal chamber that I want to light when the saber is on...and the manual says that's 3.3v would 15ohm 1/4w resistors be appropriate for two LEDs on that circuit?Sent from my iPhone using Tapatalk

If you wire the CC LED to either the Deep Sleep pad or the Accent LED pad on the NB you really don't need a resistor since both of those pads only put out 3.3v. The FV of the LED is so close the source voltage of the pad you really have nothing to worry about. Only if you go off of the main power circuit do you really need to worry. There are really almost a dozen of different ways to wire in CC LED's. You can even do more than one LED. You can wire them to turn on as soon as the board is powered, or only when the blade turns on, you can wire in two so that the CC has FoC as well, or you can even do three LED's; One that comes on when the board is powered (Power indicator LED), one that comes on with the main blade and flickers, and one that is wired to the FoC circuit. It's really your decision.

May I ask why you would prefer the Tri Rebel over the Tri Cree? The Tri Cree's are substantially brighter and just as easy to get through TCSS. Not to mention they just released the new 7/8" heatsinks (which are AWESOME by the way) and the required modified Tri Cree's to fit them.

Yes, that is forward current.

Forward current and forward voltage are NOT the same thing. The FV of a Tri Cree (blue) is 3.47v, while the FC is 1000mA (1A). These are just rough averages provided by the manufacturer, but they are more than effective when choosing resistors.

Mainly because when I did order, the tri Cree was out of stock, and admitedly, with this being my first saber I didn't know there was a difference. Now that I see it's back, I just ordered one, with the heat sink and a few 1ohm 2w resistors (a few extra just in case of screw-ups). I'm sure I'll find another use for the Tri-Rebel.

That's understandable. You will be much happier with the Tri Cree ;)
 
My copper heatsink should be here today- looking forward to checking it off the list of parts needed. Planning on ordering the chassis by the end of the month.

Ohhhhhh so no resistor for them GOT IT...that helps alot. I had pretty much drew this diagram in my head. minus the recharge port I hadnt worked that out....that was next on my to figure out list! Thanks again!
