In preparation for Makerfaire, [hwhardsoft] needed to throw together some demos. So they dug deep and produced this unique display.

The display uses two synchronized peristaltic pumps to push water and red paraffin through a tube that switches back over itself in a predictable fashion. As visible in the video after the break, the pumps go at it for a few minutes producing a seemingly random pattern. The pattern coalesces at the end into a short string of text. The text is unfortunately fairly hard to read, even on a contrasting background. Perhaps an application of UV dye could help?

Once the message has been displayed, the water and paraffin drop back into the holding tank as the next message is queued up. The oil and water separate just like expected and a pump at the level of each fluid feeds it back into the system.

We were deeply puzzled at what appeared to be an Arduino mounted on a DIN rail for use in industrial settings, but then discovered that this product is what [hwhardsoft] built the demo to sell. We can see some pretty cool variations on this technique for art displays.

The Flow Of Time Draws On A River

You would think Hackaday would see more projects from public art exhibitions. They really do have everything – the possibility to mount electronics to just about anything in a way that performs interesting but an ultimately useless function. So far, though, [Richard Schwartz's] Flow of Time is on the top of a very short list of public art installations we like.

The idea behind the build is a German phrase that means something similar to ‘time trickles away’. [Richard]‘s project implements this by printing the current time onto the surface of a flowing river in [Richard]‘s native Innsbruck.

The build uses five micro piezo pumps to dispense food coloring from a bridge. Every minute, an Arduino pumps this food coloring in a 5×7 pixel digit to ‘write’ the time onto the surface of a river.

Surprisingly, [Richard]‘s installation doesn’t require much upkeep. The pumps only use about 70ml of food coloring a day, and the entire device – including the Raspi WiFi webcam – is solar powered with a battery backup.

You can see a video of the time printing on a river below.
