This pendant is fun, easy to make, and can be enjoyed by any robot lover. Sorry for the low picture quality, my camera died and I couldn't find the charger, so I had to use my cell phone camera. Enjoy!
Step 1: Gather Materials
A small circuit board
A watch (working or not)
2 2-prong power or extension cords
A battery cover with a hole for a screw
Elmers Craft Glue
Amazing GOOP all-purpose glue
Step 2: Remove the Prongs From the Power Cables
Cut the rubber away from the plug and pull out the prongs. I used tin snips.
Step 3: Dissasemble the Watch
1. Use scissors to cut off the watch strap.
2. Use a small screwdriver to pry off the back of the watch, or if there are screws, unscrew them to remove the back plate.
3. Remove the plastic spacer and watch mechanism/face. You should now have the watch in 5 parts: the watch mechanism/face, the watch glass/frame, the back plate (you can discard this), the watch strap (discard this also), and the spacer (discard)
4. To remove the watch glass, soak the watch frame in hot water for 10 minutes, or until you can push the glass out from the inside of the frame. You can discard the watch frame.
Step 4: Prepare the Circuit Board
1. Cut off all wires and components.
2. File, then sand all sharp points.
Step 5: Attach the Guts and Limbs
1. Using super glue, glue the watch mechanism watch hands face down onto the green side of the circuit board.
2. Using goop glue, glue the watch glass on top of it and use a stick to scrape off excess glue.
3. Using craft glue, glue on the prongs in appropriate positions to be arms and legs.
Step 6: Attach the Loop
1. Turn the circuit board over.
2. Super glue the battery cover to the top of the circuit board so the screw hole is hanging off of the side of the circuit board.
Step 7: Add the Head and Eyes
1. The circuit board I used had a switch on the side of it, so I used it as the head. If your board doesn't have a switch, just glue some small, rectangular thing on as the head.
2. If the head is black, like mine was, cover the front of it in white-out.
2. Draw eyes with a sharpie.
Step 8: Done!
Congratulations, you've finished your robot pendant!
At this point, it may look messy (as you can see, mine did), but the craft glue will dry clear so it'll look a lot better soon.
You can use paper clips to hold pieces in place as the glue dries.
To add to a necklace, just thread the string or chain through the screw hole at the top of the robot.
