Blüp: The Bubble Notifier
Great find, thanks for the resource! I may pick some up for the future.
Interesting.The video cutting short before the bubble breached the surface is a bit strange.Does it hang at the surface? Does it make a soft sound? - dia
Doesn't the click from the relay provide an audible notification, before the bubble notification?If this is the case, you can simply swap the AC pump for a DC one and the relay for a transistor. - Sanderv2
This was the reason I decided to use a solid state relay so it doesn't produce an audible noise. I would like to eventually replace it for a DC pump so I don't have to have two power adapters leading to the box but I worked with what I had at the time. Thanks for the comment!
This is a really nice idea, and well documented. I have an idea for disappearing the brass tube - if you used something like borosilicate glass tube (lab supplies) instead of brass, and a fluid with a similar refractive index like high weight (viscous) silicone oil, the tube would almost disappear in the fluid.
That's great! - BradB5
Splendid idea. Aquaman would be proud! - robertchambers
