so this was what i had in mind......should have sound and more or less full brightness i think, anyone want to chip in?
thats 1000mA bp not a 700mA

That diagram will work. However, the buckpucks really need a minimum of 5v to run properly. You don't say what your battery solution is going to be. If it gets much under 5v, you'll end up with a saber making sound but no light.
I'd recommend either switching to a resistor, or using a pair of Li-Ions with a 5v regulator to keep from burning out the sound board.
We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

http://forums.thecustomsabershop.com...e-to-Ohm-s-Law for getting resistor values the right way!
yep. And I would drive the led as hard as you can. What are you using.
Going to be using a 6v (4xAAA) batt pack, so i think that should drive the buckpuck and so far it's not fried the board...so far lol
Well fingers crossed, transistors are on the way so hopefully this weekend i should have a look...we'll see what happens
Pics and vids wil be forthcoming

6 is the danger zone for the econo boards. You're kinda playing russian roulette with that one. If it hasn't gone yet, you might be okay, but you should probably get a 5v regulator for it.

Jesus pogostick what kind of Rodian clusterbomb is this? DD

If you go with 4 rechargable AAA instead of 4 alkalines the voltage will be a nominal 4.8 volts. (Mine meters out at jsut under 5.1 with a full charge.)
Dan
will 4.8 be enough to kickstart the buckpuck?

The problem isn't a 4.8 starting voltage as much as when the batteries get low depending on the led you could lose the 1 volt over led vf you need. This is why I recommend a li ion 7.4v pack with most setups and bigger batteries than 14500s if running more than 1 led die.
Well i got it all together last night over a couple of beers with my old man, seemed to work ok, but i didn't have it running for too long 1/2 mins max...
Then NIGHTMARE!!! putting my pommel back on (i have a inch or so of blade from the cheap saber for resonance tucked into it) it all caught and twisted...........oh the humanity, wires twisted and broken....the sleepless nights....
So back at it again this morning
As a side note, and I know i'm over stepping the mark, but.....does anyone know where to pick up buckpuck's in the UK? I lost one of mine (wife tidied up lol) and can't really justify $35 P+P for a $15 part....(sorry tim )
