Step 9: 4066 switch IC and Chip Socket

The 4066 switch IC lets us switch back and forth between the two nunchucks. To get the chip to fit in the board, you first need to slowly and carefully bend the leads inward, slightly. One easy way to do this is to evenly push the side against the table surface, as shown in the first image below. The leads should be nearly vertical after you do this.

Note: Your kit may have included a chip socket (only the first batch of kits shipped without a socket). This socket is used to protect the chip from the high temperatures of the soldering process, and enables you to remove the chip if needed for troubleshooting or replacement. To solder the socket in, simple align it with the notch on the PCB. Follow the same soldering steps below. Bend the leads of the IC as indicated, and push it into the socket when you’re finished soldering it.

Please the chip on the board, making sure to follow the polarity markings. The chip has an indentation at one end to indicate pin 1, and it should line up with the similar indentation marking on the circuit board. To keep the chip from falling out, you can bend two of the corner pins.

Step 10: RCA jacks

The three RCA jacks provide the audio and video signal connections with your television. Place the jack in place and push it down. There are a lot of pins here, so it might require a little force to get it in place. The fit is tight, but that\s the way we want it. The big holes might require more solder than other parts, but make sure to heal the whole pad and pin, and you should be fine.
