Introduction: Upgrade Your Egg to Mech!

About: I'm Mario Caicedo Langer, from Colombia, former Navy officer and BSc in Naval Sciences. Right now I'm Technical Director and Technology Lead Teacher at STEM - Engineering for Kids Azerbaijan. Also, I'm artis...

In Easter you can see eggs of all kinds: painted eggs, decorated eggs, chocolate eggs, candy eggs, boiled eggs, and so on.

So, I wanted to make something different with my eggs, so I created a Mech Egg!

For building it, I used plastic parts from toys and two piano keys. The egg base was made with a deodorant cap.

This instructable has two parts:

  1. How to make the Mech body (motionless) to use it as eggcup (WARNING: this is a prototype and uses plastic junk from different sources. Food safety is not guaranteed.)
  2. How to install an electric motor to transform it into a VibroMech Egg!

I'm participating in the Egg Contest. If you like my instructable, your vote will be very appreciated!

(Here is a previous instructable using a plastic egg, just in case you need more ideas)

Step 1: Materials

You can find most of the materials from broken toys. Even from a toy gun I got the motor and some cables, and the triggers from four guns where used as pincers for the robot.

So basically, I need the following items:

  • Deodorant cap
  • 4 plastic triggers from toy guns
  • 2 piano keys
  • 2 blue covers for electric sockets
  • 1 chair from R/C car
  • 1 plastic box for earplugs
  • 4 iron long pieces
  • 1 3V motor
  • 1 switch
  • 1 AA batteries holder
  • bolts, screws and iron washers
  • Assorted plastic pieces from toys.
  • Super glue

TOOLS:

  • Dremel rotary tool
  • pliers
  • screwdrivers
  • hot glue gun
  • soldering iron

Step 2: Pincers

I found two plastic pieces from a R/C car, and they look very suitable for the arms, so I drilled them and attached the triggers using bolts and screws, to make them look like pliers.

Step 3: Egg's Cockpit

Using a screw, I attached the deodorant cap to the plastic chair. Then I drilled a hole in each side, to attach the arms using screws and bolts.

Step 4: Legs

I attached a socket cover (foot) to an end of each piano key, and I attached the iron pieces to the middle of the keys.

Step 5: Attaching the Legs

Before drilling the holes, I had to check where was the best place to put the legs. I tested with a boiled egg, to verify the center of gravity of the mech, even considering the installation of batteries and motor. After that, I attached the legs using screws and bolts.

Step 6: Time to Test It for Breakfast!

Why everytime I use the kitchen, it has to become a mess?

After eating the egg, it was time for the second upgrade: VibroMech Egg!

Step 7: Motor Backpack

The mechanism works with a basic electric circuit: batteries are connected to a motor and a switch in one of the cables activates the mech.

I modified an earplugs plastic box to house the motor, and I drilled some holes to pass through the cables.The motor was fixed inside the box using hot glue. The switch was installed in the clip of the box.

Step 8: Attaching the Electric Circuit

Using screws and some hot glue, I attached the motor backpack and the batteries holder to the back of the mech.

Step 9: Unbalanced Weight

I fixed a plastic knob to the motor plastic attachment, and I inserted a screw in the knob, to add some weight.

I attached the unbalanced weigth to the motor.

I placed a new boiled egg in the cockpit and I painted a "revenge" face on it. MUAHAHAHAHAHAHAHA!

Enjoy your eggs!

    I sure am glad I found this! We have some chickens, and every once in a while foxes will break into the coop and steal eggs! Now they can finally defend themselves! Thanks M.C.!

    Nice. One of my favorite elements of this build is the legs. You refer to the pieces as simply "iron", but I recognize those; they're Sawtooth Picture Hangers (http://amzn.to/1Qu5LfX)... I have several that came in a picture hanging kit. I love how you use the existing right angles of them to form a bracket around the piano key. Then, the sawtooth design gives it a little bit of intimidating flair. Bravo.

    Thanks!!! Finally I know what's the name of those things! In Colombian Spanish we call them :serruchos para marquetería". Thank you!

    If there is something famous investigators Elmer Fudd and Yosemite Sam taught us is: NEVER trust a bunny.

    That was nice! But maybe you can add wings to the unbalanced weight to make it look like it can fly

    Thanks! Actually, I was thinking more about a saw... :-)

    Eggsactly what I was always eggcited for! I'm eggspecting him to eggsterminate the eggstroidinary humans as would any eggstraterrestial (as he is obviously an eggsexutioner). However, he may be too "scrambled" to do such a "devil"ish act of eggstremely eggsplosive and eggstravagant harm to us humans. "Hoo" knows, maybe I'm just eggsaggerating too much, but I think we should eggsercise eggstra eggceptional caution. Overall, an eggcellent instructable that leaves me eggstatic for more "devil"ish instructables.
