#MakerTherapy: Fuzzball Surprise!

by amcnicoll

Published on January 26, 2016

Prank your nurse, friends, or family by using your remote control to trigger an avalanche of pom-poms and noise when they walk into your room!

This project uses bits found in the Gadgets & Gizmos kit, along with a little bit of tape and pom-poms (or whatever you want to surprise people with).

Duration: 20 minutes

How To Make It

STEP 1 : Build the remote control

0e782984 a804 4e29 92f4 bd3dc77c39a5

Using a power (p1), two dimmers (i5), and one transmitter (w22), build the remote control. You can put it on a mounting board or a LEGO platform like we did.

STEP 2 : Build the dumper

Using a power (p1), a receiver (w21), a servo (o11), and a buzzer (o6), build the dumper circuit. We added a bar graph on the buzzer just for flair. Make sure the receiver is on the same channel as the transmitter!

STEP 3 : Attach the cup to the dumper

Attach the long servo arm to the servo using screws, then firmly tape a cup to the servo arm.

STEP 4 : Set your trap!

Securely tape the dumper circuit somewhere above the door. Turn on both circuits, and use the sliders to set your trap (buzzer is off, cup is in the upright position). Fill the cup with pom-poms, feathers, confetti, or other safe and surprising things. Once the trap is set, keep doing whatever you were doing in your room - but keep the remote close!

STEP 5 : Surprise your visitor!

When someone walks in, push the sliders to activate your prank! Dump the contents of the cup, and play with the buzzer to add to the surprise.
