This is the first step in transforming Elvis to "Elvis the Terminator," an ongoing project. This first article is about opening your Elvis to reveal some of its electronics. The next article will be about removing the skin and so forth.
So, are you ready to get started?
Support the Elvis upside down, either in an empty trash can or in your lap. If batteries are installed, you will need to remove them before beginning this step, since you could slip and make a short circuit in it. If you look at the base, you will see that there are a lot of screws to remove. Make sure not to forget about the ones in the middle of the white standoffs. See the picture below.
After all the screws are removed, it's time to start on the vest. The picture below shows that the vest is connected in the front on 2 posts. Remove these connections first by prying up on them with a screw driver, going up and over the post.
Once you have these connections loose, the next step is to release the bottom base from the upper torso. By doing this, you will be able to get to the electronics. Notice that around the bottom of the vest, there are locking tabs holding it in place. There are 2 more locking pins; one on each shoulder. By pulling up the vest from the bottom, you will come to the point where the vest won't move. Twist the locking key 90' to unlock and pull it out. See photos below.
Now that all the locking pins are removed, it's time to remove the vest. The vest on each shoulder has a connector on it. These connectors are for the IR transmission and receiving on the vest pocket for the right and left. Remove the connectors and then pull the vest up and over Elvis's head. We are now ready to examine the insides.
Finish opening the base from the torso. Be careful not to pull on the wires too firmly. On the base, you will see the pink speakers; one on the left, one on the right. The PCB on the far left is the audio amp, and the upper center is the main PCB (or "brains" if you will.) Front center is the audio interface board which intergrates the mic and audio in from the CPU and out to the speakers.
Next is a look under the shoulders. This is where the head is controlled; it can tilt right, left, up and down. Two motors control these functions in the X-Y axis using worm gears and a gear box. Notice the large silver washer. In between is a thick rubber washer, so the motor gear box can move without breaking or locking up. The board to the right of the center motor is an HBridge circuit for controlling the movement of the motors fowards and backwards. Also in the motor gearbox is a PT sensor for detecting speed and lack of motor movement. On the far left and far right is the board for the IR sensors on the vest. The center bottom board is a power distrubution board.
This ends the first tutorial of many as we transform Elvis to "Elvis the Terminator." Thank you to everyone that has helped me in the ongoing project. This will be a long undertaking, but well worth it. I hope you all enjoy it!
Stay tuned for more to come! GWJax
