The Fulcrum? Wow, beautiful saber.
Definately on my wishlist.
The search function of the forum is located in the top bar.
Below the US-logo on the top left corner of your screen.
Search button is the page with the looking glass, third button from the left.
If you want to get to the board to connect it to the computer, just lift the saber up, and gently tap the side of the saber and the speaker/batteryholder/board-unit should slide out.
And all the different tricks alike, tapping it on your hand, of if stuck, on a folded towel.
If all else failse, go from the other side, slide the LED out get a chopstick and push the batterypack out.
