WowWee's Elvis Alive to The Elivinator Project

Step 30BUILDING THE REPLACEMENT ELV-09 BOARD

BUILDING THE REPLACEMENT ELV-09 BOARD
Hope you enjoyed that I know I did when I got it to work correctly. Now lets move on to the next part.

BUILDING THE REPLACEMENT ELV-09 BOARD

First lets get the supplies ready. You'll need the following:

7 each 220 ohm resistors 1/4 watt at 5% color code (Red, Red, Brown, Gold)
7 each 1.0 uF tantalum capacitor Note the polarized lead. The + side goes to the Vdd. Do not flip these capacitor they will explode if connected backwards and will release the magic smoke inside them.
7 each VR, " Variable Resistor " a resistor that can change it's resistance by a mechanical movement, plugs from the original ELV-09 board. Use the correct color plugs. The only plugs you will leave on the original board are the green plug and the large white plug.
1 each PCB predrilled prototyping board. Make sure the board is the same size as the ELV-09 and that the mounting holes are in the correct location.

The following schematic is to be used for each VR connector. On your VRs connector the center pin on each plug is the center connection for the variable resistors. When all 7 circuits are complete connect all the Vdd connections together and connect all grounds together. A black wire will be connected to the ground or Vss for system ground and a red wire connected to the Vdd for system voltage. For all I/O (Input / Output) connections from the 220 ohm resistors I used the corresponding wire color for each plug to help identify what each wire is for. Any means of construction is suitable for this board, which means you can make a PCB with a single or double-sided copper clad board by etching out the line traces and drilling the mounting holes. As you can see I used the traditional pin wiring board building technique.

Once this board is built, next is to check all connection with your meter set at continuity check. Make sure every thing is correct! If not re-solder or re-wire it. Set this board off to the side and well come back to it.
Next is making the Eye.

Trying to figure out what the requirements are for controlling all of Elvis' components I have come up with the following I/O requirements:

16 inputs (10 from VRs, 4 from neck switches, 2 from IR boards Rx)
22 outputs (10 for each motor/direction, 2 for IR boards Tx)

Have I over looked something?

I appreciate all of your help!

I am eager to bring my Elvis alive. I am attempting to translate your instructable into Arduino (that's all I have right now).

Looks like that is the pinout for ELV-07 not ELV-09.

Have you listed which VRs (which color plug) go with which motor? I am trying to avoid taking the guts out of the face, and since i am working from behind i can't see where all of the plugs are going to.

GWJax,
I'm confused. Where are the 7 VR's? I am putting together a shopping list for this project, but I don't know if I need to supply my own VR's or if they are already in Elvis...

This is an awesome Instructable!
