8 Bits and a Byte created this automatic bubble machine, which is powered and controlled by a Raspberry Pi and can be switched on via the internet by fans of robots and/or bubbles.
They chose a froggy-shaped bubble machine, but you can repurpose whichever type you desire; it’s just easier to adapt a model running on two AA batteries.
Before the refurb, 8 Bits and a Byte’s battery-powered bubble machine was controlled by a manual switch, which turned the motor on and off inside the frog. If you wanted to watch the motor make the frog burp out bubbles, you needed to flick this switch yourself.
After dissecting their plastic amphibian friend, 8 Bits and a Byte hooked up its motor to Raspberry Pi using a relay module. They point to this useful walkthrough for help with connecting a relay module to Raspberry Pi’s GPIO pins.
- Bubble machine (preferably one running on two AA batteries)
- Raspberry Pi
- 5V relay module
- Raspberry Pi Camera Module
- Remo.tv account
- Jumper wires
The only remaining question is: what’s the best bubble soap recipe?
