	Check and double check all your soldering. Good connections here are critical to having a good flow of current. Once you've done that, seal up the connections using the Power Distro Cover Top and Bottom 3d printed parts. Then solder the 18 gauge wires to the switch and the rest of the circuit.

		+	IMPORTANT: If you test this power distribution circuit without having the plastic housings protecting the solder joints, you have to be absolutely certain that the two halves (black and red) do not have any chance of touching each other. If they touch with a battery connected, you will instantly short out the battery and that could cause a fire, burns, or the battery may burst or even explode. We assume that if you are building this project, you are very aware of how to handle circuits like this safely.

	However, if you are using modules that are not 5v tolerant, you will need a voltage divider. There are tutorials all over the internet describing how to do this, and if you are sourcing your own parts you may need to use that information to protect the modules you use.

 You can think of the harness as being in two pieces, the 9v battery side and the 6v battery side. These sides are hooked together on the positive side (RED) by the SPDT switch. Each side gets one of the two poles of the switch. The diagrams below each show a switch, but it is the same switch, just different poles.

 Be very sure that you know which side of the UBEC is input from the battery, and which side is 5V regulated output. The UBEC we use has a 3 pin Dupont connector on the output side, although only 2 pins are populated (+5V, RED wire, and Ground, BLACK wire).  This connector will be cut off and replaced by multiple red and black Dupont wires to feed power to each logic module (nano, servo controller, Bluetooth module, buzzer).

 The diagrams below shows how connections are made. As usual, RED colored wires will be connected to positive voltage, while BLACK wires are for ground.

 The Tamiya connector red wire (V+) feeds through the fuse to one pole of the STDP switch. From there, the red side of the circuit interconnects with all the red wires from 14 servo extension cords. To do this, you will take the plastic housing off the female side of the servo extension wire, peel the wires apart, and solder them onto a strip of male Dupont pins. The pins come in rolls, and you want to leave the pins connected to each other. You'll need two sets of 14 pins as shown here:

	If you purchase kit parts from Vorpal Robotics, you will receive the battery/switch assemblies for both the hexapod and gamepad pre-assembled with no soldering required. These instructions are for people who wish to source their own parts. These instructions assume you are familiar with soldering, stripping wires, and other basic electrical tasks. There is just enough detail here for people who are experienced in building circuits to make the parts. It's beyond the scope of these instructions to teach the basics of electronics.

 You then take a piece of red hookup wire (18 gauge or thicker) and cut a piece 16 inches long. Strip enough of it to lie across all 14 pins. Connect all the red wires from the 14 servo extension cables to the pins. Solder everything together. It's important that every pin is soldered to the 18 gauge wire. Even though you do have some backup to keep the circuit connected due to the pins being connected together, the thin metal may not be able to handle enough current. The red side will look like the following diagram.
