Inspired by a Jeep’s falling water display, Matt Bell created an Arduino-based bubble display, which turns Jeep’s idea on its head. Matt’s latest version makes a few key improvements that help with the bubble size and steadies the speed at which the bubbles rise. For consistent bubble movement, Matt recommends using mineral oil and keeps each “bubble channel” (as I like to call it) in its own vinyl tube. We’re looking forward to seeing the improvements that the next version brings! [via Arduino]

  1. CCCKC Hackerspace member! Here a few pics of his rig just prior to switching to mineral oil. He has got something else planned for Maker Faire Kansas City that will be awesome too!

  2. Consider linking to TAOMC’s Pipedream art installations, from over a decade ago and still operating:

    He also invented the Eggbot that Make sells now.

    STE Oil Company sells mineral oil in the quantities needed for a project like this. My one order with them was smooth.
