Mischief Machine

by emily_littlebits

Published on October 3, 2016

Create an invention to make your parents shriek, EEK! With the press of a button on your phone, you can pull this prank on unsuspecting friends and family. Control the robotic arm to rustle whatever you put it into - is it a mouse or a monster? Who knows! Just hope they don't prank you back.

 

These instructions correspond to the Gizmos & Gadgets Kit: 2nd Edition. If you have the first edition of the Gizmos & Gadgets Kit, please refer to those instructions. They can be found here.

 

HOW IT WORKS:

  • The p1 power Bit provides electricity to the circuit.
  • The w30 Bluetooth low energy Bit is connected to the controls on your smart device via Bluetooth. The controls in the littleBits Invent App determine how much signal the Bluetooth Low Energy Bit passes on to the next Bit. 
  • The position of the o11 servo depends on how much signal it receives from the Bluetooth Low Energy Bit. 

 

When you're done building your invention, keep the fun going by following the invention cycle below!

 

PLAY: Where can you hide your mischief machine? Could you stick it in a drawer or under your brother's bed? See how many people can you prank!

 

REMIX: What new mischief can you cook up?

  • MAKE EVEN MORE MISCHIEF. Add light and noise to your Mischief Machine to wreak more havoc. 
  • TAKE CONTROL. What control can you use to make the interaction more stealthy, or more fun?
  • PUSH THE LIMITS. Your Mischief Machine can be used for more than just pranks. What other ideas can you cook up?

 

SHARE: How loud can you make someone scream? Take a video of your prank in action and share it on the littleBits Invent App.
