An air-bubble clock is a glass vase into which liquid is poured, and air bubbles rise in a certain sequence from below. The photos above show that the bubbles create figures of the heart and two, and below you can see how it looks on the video.
So, for the manufacture of such watches, the master used the following
Tools and materials:
- Solenoid valve DC 5V - 8 pcs.:
-air pipe for eight exits;
-compressor for the aquarium;
-Tubes;
-Connectors;
-Acrylic;
-ESP8266;
-OLED display;
- Extension module MC23017;
- NeoPixel LED strip - 8 pcs.;
- MOSFET 2SK2412 - 8 pcs.;
- IN4002 diode - 8 pcs.;
- Power supply 6V-1.8A;
-Glass vase 120mm X 260mm;
-Glycerin 99%, 2.5 L;
-Plastic box;
-Glue;
-Laser cutter;
-Soldering accessories;
Step One: Laser Cutting
From acrylic cuts out the details of the watch.
Step Two: Build
Assembles a block of acrylic. Installs pipes, brings the tube. Assembles a unit with solenoid valves.
Step Three: Wiring Diagram
The ESP8266, connected via WiFi, controls eight solenoid valves via the MC23017. The display will show the characters duplicate characters in the vessel.
Eight NeoPixels are installed in a line glued to the acrylic part, which should be located under each air nozzle.
After assembly, two liters of 99% glycerin are poured into the vase.
Step Four: Code and Settings
Code can be downloaded here
It is necessary to configure the valves and their opening parameters in the code. Depending on the glycerin temperature, it is necessary to correctly set the valve opening time, closing delay, opening frequency.
