Never-Ending Bubble Machines

Never-Ending Bubble Machines are automated to maintain a constant level of liquid in the device.

Connecting a Never-Ending Bubble Machine to a large reservoir eliminates the need to manually re-fill the device.

Never-Ending Bubble Machine Wiring Diagram

I came up with this idea years ago, shortly after purchasing Bubble Machines for Music and a Movie.  As much as I love the joy of my Bubble Machines, I found that I did not enjoy constantly refilling them. 

Bubble Machines are such an amazing thing!  They create more bubbles than one person could blow on their own!  Never-Ending Bubble Machines don’t require someone to refill the liquid when they run low.  Because of this, they are a great addition to any event.

Make your own Never-Ending Bubble-Machine!

    Process:

    1. Open your bubble machine and locate where you will install your components.
    2. Drill holes for mounting your components.  For my build I did:
      1. 3/4″ hole to the back to the right of the fan for the switch.
      2. 7/32″ hole on the front right for the tube. 
      3. 5/32″ hole on the left for the float switch wires.
      4. 7/32″ hole on the grill (left 4 down 3) for the pump nozzle
    3. Cut the two (usually black and red) wires between the capacitors and the fan.  This is where we will attach the new circuit.
    4. Wire the circuit according to the diagram.  Pay close attention to the numbers (30, 87, 86, 85) as each relay harness might have a slightly different color scheme. Be sure to use heat-shrink and solder each connection securely.
      1. Negative (black) wire will connect back to the fan, the neutral (#1 or off colored pole on the LED switch) as well as 85 on the relay and the negative (non marked) side of the pump. 
      2. Positive Wire (red) will connect back to the fan, as well as the #2 center pole on the switch.
      3. The 3rd post on the switch will connect to 30 on the relay and the float switch.
      4. The other side of the float switch will connect to 86 on the relay.
      5. The postive (marked red) side of the pump connects to 87 on the relay.
    5. Confirm all wiring is correct and test the circuit to ensure the float switch is set to turn off when raised.  If not, reverse the float.
