Work in Progress. Racing to the final 100 meter Stretch. September, 2019.

At the end of August , 2019 I finally resolved the issue of the punching sound created by the pressured air entering balloons. For the longest time I thought the balloons require higher pressure to inflate and deflate to the desired sizes that I wanted. The sound of the forced air was very unsettling and distracting. I was about to give up and allow the sound as it was. Then I began to think and play around again. I had the source air valve that control the main air flow at a quarter-turn to let air-in slowly. Secondly, I decreased the localized pressure control gauges for both sets of balloons from 80psi to 60psi and finally settled at 30psi. After the pressure control gauges were down to 30 psi I adjusted the two signal valves with timers which control the amount of air in and out of balloons. Each signal valve control a set of 16 balloons . The front 16 balloons which get more air easily because there is direct air flow from the air hose, the timing is set to let air in at 9 secs in and 4 secs out. The back burner 16 balloons cannot compete with the front 16 so the timer for air-in is 15 seconds and air-out 9 seconds.

The lowering of pressure had cut down the forced air sound to a satisfying decibel level. The air intake for the front 16 balloons was set to 9 seconds compare to the back 16 balloons of 15 seconds so more air could be distributed to the back 16. The 9 seconds air-out setting for the back 16 was for more air to remain inside the balloons. However competitions for air between the balloons are relentlessly fierce. The front 16 still has better air supply.
