MR FX sound modules schematics and discussions

Also keep in mind that when installed in the saber the hilt is part of the heat sink too and every LED will get a little hot.

I know, this is my sixth custom saber. The led was getting unusually hot. Using a 2.2 Ohm 2 Watt resistor solved the problem.

Hello guys, question to this sound module:

Does anyone get this type running? I wired it classic way: Brown to positive LED all others to negativ LED. I used original 5 connector/6 batteries battery pack.
But when I connected any combination of switch wires nothing happend. I'm sure the LED is working. Any hint?

What board is that? Where did you get it? I need a bit more info to help. Just to hazzard a guess at this point, there should probably be a clash sensor hook up somewhere in the bunch for the led. That is likely one of your issues.

I bought it in auction. Im not sure what exact type it is. It should be Master Replicas because it is using 5 connector battery pack and I recall it should be master Windu. Clash sensor is hooked up so no problem here. For complete assembly look on photo:

(Dont look for brown colored wire for positive led, I replace it.)

Ah, now we are getting somewhere. Okay the diagram for the link is broken. Here Is the link to the thread. Maybe some one will chime in and re-post the picture. IIRC you use the two purple and the grey wires, but you may try a different combination of the four, say 2 purples and green. You need either a latching SPDT or DPDT switch. That particular board requires a NO and NC contact to work. Hope that helps.

Ok It looks that the board is dead. Still nothing even after I connected switch according to diagram. If I have exact same model I would try to find if there is some demaged part but I dont. So thanks for help.

Hi guys, i have the board of an MR LUKE ANH 2007 which looks like this;

And it doesnt run. I suspect that when I took my multimeter to the batter/speaker housing i only got 2.4volts coming from it. Is that why it isnt working? Should it be 4+volts?

Couldnt find exactly where to put this...but I have a yoda lightsaber that lit up but made no sound. Thanks to this fourm I was able to disassemble and troubleshoot my issues. I was able to get sound to the speaker but the problem is, the sound is very very faint/weak. Why would that be? Poor connection somewhere or a power issue?
