View Full Version : Corbin and MR board wiring help

My friend and I are wiring up my saber (Corbin Driver and MR Vader board), and we're having some trouble. Most everything was wired before I got it, and I've just had to add the LED, battery, and new switch. Before adding the new switch, we soldered the LED (which looks like a textbook solder), and added the battery as per the schematic. When we added the batteries and turned the saber on, nothing but the accent LED was working. No Luxeon light. No saber sound. Nothing.

What did we do wrong?

I'd need a pic of the whole circuit to tell you anything, I can't make heads or tales of it the way it is.

Here's a picture of the complete ciruit.

Green coming from the Corbin to the speaker... WHY? That's why... your board won't get sound or light that way. Your Corbin board isn't getting any positive power and the MR doesn't have the speaker with the positive (thus the accent LED light but no sound).

Ah. So instead of wiring the speaker there (which was wired before I got it), the positive battery should go there?

Sorry for the double post, but now the MR board is working, but the LED still isn't.
Here is a pic of the wiring (sorry for the quality). If the wiring is right, should I re-solder the LED?

I think you have the wires to the LED wrong, from this last pic it looks like the leads are soldered to the unused tabs on the star hex base, the emmiter itself is only attatched to two tabs which both have a lead from the emitter itself going into them. at least thats what it looks like to me on the one I'm staring at, I'be never done one of these before.

The corbin board and mr board and speaker positive wires all go togeather, so thats 3 pos wires and 2 neg wires, the brown wires on the mr board is a speaker neg wire. that goes to the speaker.

I put up the diagram in the wiring and diagram forums.

he's got all that working, I'm pretty sure he needs to re-solder the LED, it looks to me like he's soldered the wires to the wrong tabs, If I'm thinking right that is. I'm assuming that the two tabs with the leads from the emitter going directly to them are the ones you need to wire to, is that right? if thats the case he just needs to hook the wires to the right tabs.

All the LED tabs work fine. As long as the positive LED lead is on a positive pad and the negative LED lead is on a negative pad, you'll be fine.

Yep hes just got to get the cobin board, mr board, and speaker positive wires to the same positive wire on the battery pack, the other speaker wire needs to go to the brown wire on the mr board. then the cobin and mr board negative wires go to the negative wire on the battery pack.

Yeah, you're right. I've got all that working now, but I'm having a new problem. I'm trying to add one of the red push-button switches instead of the existing switch, but only the board or the LED works with th eswitch at once. Is there a way to get the LED and board to work with the single switch?

SPDT or go back to a DPDT. I don't remember if the SPDT diagram is still around or not...

see thats why I post here people actually correct me and I learn things:-P

Agreed, this is THE most helpful board I've ever been on.


Sadly, the saber's on hold. The LED is broken, and I need a 4AAA battery pack to fit inside better than a 4AA pack. I'll post pics of the build once I get the new parts. Congrats to Tim though, the saber's powder coat is amazing!

maby try getting a resistor to run the led without any electronics driving it, it could be a rare dud, or, it could be as simple as you connected it backwards, and it could be a odd as the factory connected it backwards.... it's a diode, so it will only work in one direction........sorry, i'm just an idiot attempting to help.....i'm just thinking in terms of "it's not your fault" considering the help from master builders in this thread...

maybe i should start reading more to see if there was a solution before commenting.....like i said, i'm an idiot....

The LED might be fried by now. Luxeon LED's are not forgiving when being hooked up wrong. Give it the wrong wiring 1 time and POP dead LED.

You need a voltmeter to measure the voltage at the terminals of the LED. If the power is there (around 3v), and the polarity is right..., the LED is dead.

But I thought the lux leds were like diodes, only letting power go thru one way?

Or is it setup on the lux leds to act as a safty to keep power from running thru and killing the circutry on the other end?

Right, they only let current through one way. So you are not going to fry a Luxeon by hooking it up reverse unless the voltage is VERY HIGH.

What I was referring to was hooking up the Luxeon the right direction, but without enough resistance in series. So several amps goes surging through the LED for an instant and fries the traces on the silicon.

You get a quick bright flash... then no more LED.
