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!

<p>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.!</p>
<p>Thanks to you, JagerO! :-)</p>
<p>Egg!</p>
<p>EEEEEEEEEEGG!! :-)</p>
<p>Nice. One of my favorite elements of this build is the legs. You refer to the pieces as simply &quot;iron&quot;, 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.</p>
Thanks!!! Finally I know what's the name of those things! In Colombian Spanish we call them :serruchos para marqueter&iacute;a&quot;. Thank you!
<p>u r right buddy</p>
<p>Yep</p>
<p>Surely. Bunnies are more evil. [&gt;_&lt;]</p>
<p>If there is something famous investigators Elmer Fudd and Yosemite Sam taught us is: NEVER trust a bunny.</p>
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... :-)
<p>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 &quot;scrambled&quot; to do such a &quot;devil&quot;ish act of eggstremely eggsplosive and eggstravagant harm to us humans. &quot;Hoo&quot; 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 &quot;devil&quot;ish instructables.</p>
<p>I'm eggstremely sorry for &quot;hatching&quot; my previous comment.</p>
<p>EGGNOUGH IS EGGNOUGH! You really exeggerated it! :-p</p>
<p>Thanks you for sharing this~ Great to see another awesome project~</p><p>Hope your day shines~</p><p>sunshiine~</p>
<p>Thanks Sunshiine! The same for you and your family! :-)</p>
<p>KILL ALL EGG CARTONS!</p>
<p>Feel the rage of my Eggcecutioner!</p>
That's one surly egg! The Easter bunny had better watch his back this year!
<p>Thanks, eLVirus88!</p>
<p>Jay! Easter ante portas! Let those eggs slaughter some bunnies xD</p>
<p>Thanks!</p>
<p>Eggcellent!</p>
<p>Thanks!! This Easter, it's time for an eggstrem adventure!</p>
<p>Das One Bad Egg!!!!!!</p>
<p>Thanks!!!</p>
<p>whoa.why is he evil?</p>
<p>He's not evil. He's fed up of watching his brothers to be hunted every Easter. It's time for a revenge!</p>
<p>I LOVE the 'revenge' face!!</p>
<p>Thanks wold630!</p>
