Trick Or Treat

Halloween Guide for Servomotor Lovers

There are two kinds of people: those who start preparing for Halloween in March, and those who prefer to see pumpkins only in their soup. 

Tech-lovers are the most innovative bunch among the first kind. They aren’t satisfied with a couple of candles on the window and the ready-made door decorations. Nope. They turn on all their creativity and knowledge to make the spookiest decorations ever and make you feel a bit lazy and not Halloween-ready enough.

In this article, you will find the coolest Halloween DIYs that have in common one secret tech-ingredient – servomotors. 

Servos are widely known among robotic lovers, as they are used in industrial robotic joints, robotic arms, robotic legs, and other movable parts of robots. But with simpler hobby versions ordered on Amazon and DIYs listed below, you can create a perfect smart decoration by yourself. 

Here are the ideas for the 3 most important heroes of every All Saints' Eve.

PUMPKINS

DIY 1. I’m watching you

  1. Foam pumpkin
  2. Eye balls
  3. Micro servo motors  
  4. 1" PVC couplings
  5. Arduino microcontroller uno
  6. Breadboard
  7. Wire

You’ll get:

A bug-eyed orange monster that you can use as a security guard at your front door. But caution! If you look at this mutant-pumpkin too long, you may get scopophobia.

DIY 2. Sing with us

You need:

  1. Foam Pumpkin
  2. Servo motors  
  3. Arduino microcontroller uno
  4. PCB prototype board
  5. Assorted headers
  6. 5V regulator
  7. .33uf capacitor + .1uf capacitor
  8. 3 resistors (~600 ohm)
  9. 6 LEDs 
  10. Insulated wire
  11. 9V battery clip + 9V Battery
  12. 3 plastic knives
  13. 3 small hinges (I used 1.5'' and 2'')
  14. Masking and electrical Tape

You’ll get:

A pumpkin family that looks just like me when I am watching the Voice. They open their mouths so naturally that you wouldn’t believe it’s lip-syncing.

No time for hi-tech pumpkin ideas? One minute till Halloween? Use this one option:
