The (wall of) Ubiquitous balloons, (in progress)

A balloon artwork running upon MQTT communication.

Description

Fig.1 Two designs of the unit out looking. 1. The balloon is on a little box, all the control system in the box. 2. Balloon laying in a cubic frame, a box contain the control system put under the frame.
Fig.2 One potential setup of the spreading balloon installation.

MQTT and the Control System

Fig.5 Sign in with user balloonUnit01. Could not send and read messages under balloonUnit02 topic.

Design for Unit

ESP32, EPS12, ESP8266, Arduino Nano 33 IoT

Fig.6 All chips I test, from left to right ESP32, ESP12, ESP8266, Arduino 33 IoT

Diagram

Fig.7 Diagram of the single unit.
Fig.8 Airflow Route.
Fig.9 Valve1 Have a metal hat to lock to protect the tube fall off. Valve 2 only has a ring to lock the tube.

Some Test of the Air

Video.1 The pip slows down the airflow.
Video.2 First Pump I got, super not powerful, running at 12V 60W.
Video.3 Second Pump I got, super powerful, running at 220V 600W. After the video, the balloon exploded.
Video.4 Test the assembled system. Valve working great. But after this test, I add the plastic Y-connector, air emitted from it. Eight new metal connector is on the way.
