Quick Qustion MR sound with 5w

[Crashteam85]

My next saber is going to be a 5w and I wanted to run the MR sound board on it, will this work the same as my 3w or will something melt with that much more juice....

Thanks guys!

It won't even run if wired like a normal III. You don't want to just add more batteries either as that will make the board fry...

There are some ways of getting it done:
-A relay from the MR board to a resistored setup. I hate relays... some boards work with them and some don't.
-On a battery pack tap it for 4.5V out of the 9V that's more appropriate
-Seperate batteries for light and sound
-5V regulator to board

They all have draws backs be it size, inefficient, or generating heat.

I think I could live with the seperate batterys for light and sound.

I may need help with a wiring diagram though, my little brain just can't do it in my head like It use to

Thanks!

Easiest thing to do would be a DPDT switch. Just wire them seperately on different sides of the circuit. The MR board just doesn't like to play nicely otherwise...

theres a way to do it but you need a voltage regulator.

[Crashteam85]

If there was a fairly simple way I could get it to work without an extra switch that would be cool, I was kinda praying for a flawless saber on this one because its going to be my Halloween costume prop.

Im not the most inclined when it comes to circuits and such so I may need some further explanation.

Then you should stick with a Luxeon III mixed with your MR board.

There are two issues to look at this...

Two battery packs or one. A Single pack means you have to tap the packfor the right voltage or use a regulator to not fry the sound. A regulator is hard because they get REALLY hot and practivally deserve their own heatsink.

Two switches vs. one. For one switch you need a DPDT or a Relay. A DPDT is essentially two switches in one so that's relatively easy. The relay option would allow for the simplest switch, but the some board play nice with it and others don't. If it doesn't it's a lot of work to eliminate the crazy chatter it does.

Xwing, Id be willing to give the relay a try, Can you link me to a wiring diagram of where it would go in the circuit and what kind I would need.

Thanks

the relay only works with the mace mr board, I havent seen it work with any other board.
