My experiment with a jo jedi (616) board

[pceptimus]

This is something i started after reading a few posts over on jssdc getting a brighter blade by bridgeing the resistor on the board.

Sorry about the poor quality vids im nervious on camera and tend to say erm a lot

Pics of the resistor i Bridged:



A video of me touching the wire in the soldier joint of the resistor to show the brightness difference:



A video of the ramping effect in the blade:



And a couple of pics in 2 different blades:

Most excellent!

Definitely makes for a brighter blade by bridging that resistor.

Good show!

What about on Jedi setting? is there anoticable difference there?

works on jedi setting too

Too bad you don't have a multimeter to check out the actual ma output. But it's great to know there's a noticeable increase in brightness with that resistor bridged! Goodbye DPDT/buckpuck setup for my friend's JoeJedi'd saber; I don't have to spend time trying to find a new switch and do some more complicated wiring...and it takes up less space! Hoo-rah!

I just wonder if bridging the resistor is going to have a deleterious effect on the board after a while.

i would answer but i have no idea what that meens im just a humble Taxi driver. but i have run this saber till the batteries ran out and had no problems with the board. remember the board is running 3 aaa battiries wich is 4.5v and that has to be split between sound & light.


gundamaniac gravy is going to test it with his multimeter we shal know soon enough

[gundamaniac]

Awesome. Can't wait to hear the results =D

I too am hoping it pushes out more than just the 350...

Pceptimus... THANKS for trying this out!

Gravy and I can help. We have a throng of 616s that we've been hoping to "coax" into spitting out more than 350mA as well.

It seems clear that if the saber board "allowed" all 3 colors to be on at the same time... it could spit ~1A like its "father & mother", the original FX board.

Bridging that resistor might certainly be allowing more current to the LED... in fact, I'm almost certain of it. Grayven can certainly meter for that since he has a MM. I would, but... he has all 7 of my 616s, hahah!

I would imagine what Lori is saying COULD come into play... but we'll never know until we try it long term, so... I'm willing to risk 1 or 2 of my 616s with that. Anything to get away from the 350mA garbage, heheh.

I also imagine that the voltage might be more of an issue vs. a current range of 350mA to ~1A. I'm going to guess that giving the board 3.7v to 4.5v would be fine, even if we allowed the board to pull 500mA or 1000mA. Further, I'd expect 6v would be the max (still guessing), and it'd be no surprise that 7.2v would destroy it.

Gravy? We need some GEEEEERRRRRRRRRAAAAAYYYYVVEEEEEE!!!!!
