It's a known issue if you connect the speaker to the tip42. You gain the flicker effects, but you lose a ton of brightness. If you want to have full brightness, you'll have to connect the tip42 to the 3 LED (-) lines instead of the speaker.
I don't think anyone has found a workaround that keeps the flicker AND the brightness.

Tanks!
I can live without the flicker effect but I dont want the flash on clash and just one switch...
-
I try somthing : I buy NPN-type switching transistors...I lost the flicker effect but the light is well fine. If you know how to have the flicker and good light just ask, but I will wire in that way! tanks

The best thing to do is to just get one of the new Ultimate FX Hasbro economy sabers and use the board from it. You don't have the blinking on power on/off and it actually has pretty good LED output if you combine the LED wires and use 6Volts or use 4 NiMH batteries. The only difference between the PNP and NPN transistors is the polarity of the base.

I already have ultimate fx and I hate flash on clash and mine are anakin board and the led is many led together in the blad...

sorry if this has already been addressed. 82 pages is a LOT to skim through so i might have missed it. has anybody tried using a capacitor to make the LED fade in/ fade out? is there even a way to make it work like that with a DC current? also, if it is possible, what kind of capacitor would be good in a 6v setup?
-
Also sorry if this is somewhere amongst it all but I couldn't find it - we can't get tip42g in Australia, is there another transistor that I can use? What specs of the transistor do I need to look at? Thanks

Here's the important bits:
Transistor Polarity: PNP
Collector- Emitter Voltage VCEO Max: 40 V
Emitter- Base Voltage VEBO: 5 V
Maximum DC Collector Current: 6 A
Continuous Collector Current: 6 A
Power Dissipation: 65 W
Find something along those lines and you'll be fine.

NOOB question here... but is there a reason we cant just hook the LED into the speaker output without the transistor? i was messing around with my first build and touched the LED + to the speaker + and grounded the LED (with the resistor of course) and it was actally pretty bright! there was a SLIGHT flicker but not nearly as pronounced as the flicker you get with the transistor. i dont have a multimeter handy at the moment tio check the voltage coming through that wire but it may be the fix everybody has been looking for to eliminate that god awful flashing. thoughts anybody?

That's how I have mine run. And I've done it with 4 different sabers using the seoul P4 leds red, blue, green and white. I've used the obiwan, anakin, Qui Gon and Mace Windu econo boards. The best ones to use are obiwan, quigon and mace. the anakin boards are wider and slightly more dificult to work with. And on two of them there are no resistors from the speaker to the led. The output voltage from the speaker is somewhere around 5.5 volts. I don't remember the milamps. They are very freakin bright! :cool: Just be sure to run your positive lead (+) from the light to the speaker and your negative (-) lead to the battery pack. It gives it a nice little flicker effect but not overly produced
