Help installing windu sound board to drive led

[airsoftmode]

Hey, i picked up a mace windu hasbro saber and took the sound driver, motion sensor, speaker, and clash detector out. I was wondering, can I use the leads that normally powered the hasbro lightbulb to power my led? And if so will I need a resistor between the LED and the sound board to regulate voltage. FYI I want to use a 5w blue led in my saber and that requires aprox 6.8 forward voltage for optimal brightness. O one last question, which battery holder should i use, it has to fit in the MHS. Thanks a lot for the insight guys.

You can't run it off of that Sound Board, but can should run a relay with that setup. Do-Clo can fill you in on all of that info.

As far as the battery in concerned, I would suggest the battery pack Tim sells and installing a recharge port. (After spending $40 in non-rechargables I'm never going back) Or a 4AAA battery holder with rechargeable batteries.

Info on Recharge Ports


As for the exact power requirements of the 5w LED I am not the one to ask. James and Do-Clo have more knowledge in that area. But I think that Tim’s pack will be sufficient.

Edited to remove my own stupidity.

You will not be able to power the 5W with the Hasbro. Sometimes you can dispense with a resistor and have the Hasbro power it, like with a 1W or 3W, but there is no way the board will take that much voltage that is needed for the 5W.

You are going to need a voltage regulator to bring the voltage down or a seperate power pack all together for the Hasbro. In fact a seperate one is the best solution for wasting less batteries throwing off heat (a regulator will get hot). Hasbro's are extremely finicky when pushed past their normal voltages.

AAA's in a square fit fine. AA's can only be three in a triangle or two across. 9v's fit fine.

simple answer is no the mace board will not drive a 5w LED. check out this thread. This will give you a longer answer.

Basicaly this board will only handle 3v and power a 1w LED or bulb.

ok.... bummer, so it looks like my best option would be a seperate power supply for the board and my led, is there any way i can wire the switch tim sells to complete both circuits at the same time, so i can turn the led and sound on with one switc? Also would 2 9v batteries be able to power the led and the board (so basically one 9v for each)?

With a relay.

You don't want to put any more than 3v on that soundboard.

ok, whats a relay?

[xwingband]

Does the Mace board have the flash on clash? If so, don't worry about it. The relay wouldn't work that way.

A Relay uses the power from one power source to apply power to a device using another power source. An electronic switch.

Example: You can use the sound board to control the relay, the relay switches on the power directly from the battery to the LED.
