Originally published at: https://www.makersmakingchange.com/project/switched-adapted-bubble-machine/

The switch adapted Paw Patrol bubble machine is a fun way for children with disaiblities blow bubbles and play with their family and friends.

This modification, created by the HuskyADAPT group at University of Washington, allows a single switch input to spin the bubble wand and blow air.

Tools you’ll need:

  • Philips head screwdriver
  • Soldering iron with solder
  • Drill with 5/32 drill bit
  • 3.5mm mono jack
  • 22-gauge wires, two 20cm lengths
  • Wire strippers
  • Zip tie

Instructions:

  1. Carefully disassemble the toy to reveal the internal wires and hardware.
  2. On the rear plastic shell, mark the spot where you’ll insert the mono jack.

  3. Using a 5/32 drill bit, drill a hole making sure to avoid hitting any internal motors.
  4. Prepare the two 20cm length of 22-gauge wires. Strip both ends of the wire to reveal the two internal wires, one sheathed in plastic and the other exposed. Twist the exposed wire.
