Bubble Display Overview Video

I spent a lot of time last summer and fall building this 62″ wide bubble display. So much time that I didn’t get a chance to edit together and post an “overview” video showing the whole thing in action. Well, here is that video. If you are looking for more build details just read all my posts tagged with “Bubbledisplay”. If you just want to sit back and watch the whole thing come together via videos, start watching my “BubbleDisplay” channel on YouTube At the beginning.

I wrote up a description of the custom shift register driver board here:

You can download it and build your own if you need to.

The motors are surplus air pump motors typically used for blood pressure monitoring systems, I purchased them from mpja.com (http://www.mpja.com/12VDC-Mini-Air-Pump-USED/productinfo/18831%20MI/)

Hello,

I think you should inject the same amount of water that moved by a bubble in the tubes where you do not send a bubble to kept the alignment of your bubbles, if possible :p

That would solve the problem…but then I’d need a water injector AND an air injector for every tube…at least doubles the complexity ;<

how did u control the air flow form pump. it does not seem to b continuous , did u use some kind of timing mechanism ?

ron: The power to each of the 60 air pumps is controlled via a cascade of serial shift register. You can read about the circuit here: http://www.summet.com/blog/2012/08/05/serial-shift-register-mosfet-driver-version-1-1/

You can watch a video of the “insides” of the system here:
