driving a lux III red

[Darth_DevilGuy]

hey all, with the LED's now in stock I'm just about ready to order the parts for my first saber, I'm having a little trouble with how to power it though, being a Darth by nature I'm building one with a red blade, but from the chart the red III draws a lot more MA than the other lux III's so how do I drive this bad boy?

I'm inclined to think two 700 buckpucks, giving it the 1400 MA it wants, but am I cutting it a little close? and if two buckpucks is what I should use what would that circuit look like? my knowledge of eletronics is limited, but putting them in line on the circuit one after the other would just result in 700ma to the LED right?

edit: I've looked around a bit, I haven't found anything on the net or in the circuit diagrams section that would tell me how to wire an LED with two buckpucks, any help would be appreciated.

I might be wrong, but I don't think using two buck pucks will work the way you think it will. I would either go direct driver with the 2.2 ohm resistor or wait til the LuxIII Drivers are back in stock. Heck, the resistors are cheap, you could get one to wire in until the driver boards a re back in stock.

ok good advice, any idea if the standard AA or AAA battery packs will work with that?

Ummm... sure it will. You take both bundle all the like wires, positive battery,neg battery, pos LED, etc with each other. The only difference is there is one battery source, one switch and one LED.

So in order to get 1400mah out of 2 700's you just put all the like wires togeather, then a wire comming off them to th eplace they need to like like batt P/N, led P/N, ect ect.

So couldent i theroretically do the same with my corbin/mr setup for a red's or a k2's?

another question, if I wanted to wire a hasbro board to this for sound would branching off another set of leads from the switch to form a parallel circuit?

essentially if I ran three positive and negative leads from the switch, two of each to the buckpucks, and the remaining set to the hasbro board, would it work, or would I fry something?

Not sure what you mean? Pair the MR and Corbin's? I'm not sure... I don't think I'd bother. One is regulated and the other is for all purposes just like a resistor.

Darth_Devilguy, Not sure what you are going for either. Hasbro's (momentary) usually don't mix with the buckpucks too well. If you built a circuit that uses the momentary and the control leads I can see something... I'm not sure anyone has gone to those lengths though.

basically I want to use the hasbro board for sound but not for the LED itself because it's output would be pitiful, so I'm wondering how to wire that, and run it off the same battery's and the same switch if at all possible.

essentially what I was thinking, was run two buckpucks with the wire's bundled like you said, then have the hasbro board attached the same way, with it's own set of positive and negative wires running strait from the switch, would it draw the power it needs or would it just fry?

[Hasid Lafre]

Yeah I was thinking of paring up the led p/n on both the mr and corbin boards to get effectivly 1900mah.

But thinking about it Iam not sure if that will work, not something I want to try and end up frying a board.

Yes wither of them will.
