MWS 700mA Buckpuck with Charge Port

[Darth Animus]

Hi guys

I have recently built a new saber with a Rebel Deep Red, 4 AAs, red ring AV switch, and the MWS 700mA buckpuck. My question is how would one hook up the standard charge port?

The puck description says there is a hookup for the port, but it only has two wires. How do you attach this to the 3 prong port?

Thanks in advance

Go to this thread, http://forums.thecustomsabershop.com...Wiring-Diagram, and look at the hand drawn diagram made by SlothFurnace 5 posts down on the page.

Not that it is hard to wire as shown on sloths diagram but you do not need to use the 3 pins with the MWS buckpuck as long as you only charge when the saber is turned off. This is because with the saber off the power to the buckpuck is cut off unlike how it would be with a PC for instance. I am not sure that charging with it on would even hurt the buckpuck but I figured better safe than sorry and why charge with it on anyways.

So looking at that diagram... I would use the center negative lead to connect to the puck?

I would wire it up just like Sloth's picture, regardless of the buckpuck's ability, for several reasons. 1) it will allow for the use of a kill key, which helps save battery life when not using the saber. 2) If one day you decide to upgrade to a PC soundboard you won't have to make changes to how the port is wired. 3) If you ever sell your saber and the new owner wants to upgrade it, they won't find something unusual under the hood.

So looking at that diagram... I would use the center negative lead to connect to the puck?

Center negative goes to the battery, Left-hand negative goes to buckpuck, Right-hand positive goes to both battery and buckpuck.

This is not true as the MWS buckpuck setup completely kills the circuit when the switch is off unlike a PC or some other device that has to stay awake enough to sense if the power switch it turned on. But like I said, no reason not to wire it up the way sloth shows.

Ok, I just want to be sure. Where I'm confused is the puck has an R+ and an R- connection, which came with a JST connector pre-attached. (Currently not connected to anything.)

The description says "Recharge Port (R+ and R-) This simply goes straight to the battery. Only charge with switch turned off."

Should I unhook that JST, and wire it up like this? Soldering to the port, but using the screw connectors on the puck?

I forgot that the buckpuck had a separate input for recharge port. Eliminate the extra wires going from B+ and B- to the + and - on the recharge port and you have what you need. All you need is R+ and R- going to the port.
