 The less complexity the less that can go wrong. For dealing with the always critical onlooker, just tell them you are working on a one degrees of freedom soft robotic actuator. Which is what I ended up making. The less complexity the less that can go wrong.

-Around the time I was working on this our community Makerspace got visited by the neighborhood committee. They were looking to spice up the local winter festival with some technology. The prototype bubble turned into an "art" installation of 17 independent bubbles that could change color via Neopixels. Scaling the prototype and making a fitting enclosure for it took a lot of effort. But with tons of help from my awesome fellow Makerspace participants we managed to finish the installation just in time.+Around the time I was working on this, our community Makerspace got visited by the neighborhood committee.

 The winter festival is a weekend long event with, by and for our neighborhood. It's free and anyone is welcome to visit. The soft robotic bubbles garnered a lot of attention especially with the many kids at the festival. The bubbles themselves proved to be very robust which made the installation weirdly interactive. It is nice to have something to show for your work and I really enjoyed my time at the festival. The winter festival is a weekend long event with, by and for our neighborhood.

-The festival bubbles have some unresolved challenges. Time constraints made the neopixels run a selection of the code used to test LED-strips.Thankfully the Adafruit strandtest.ino code has some beautiful parts, especially the rainbow chase can be quite nice. Another weak point was that it wasn't possible to control the airpumps and the neopixel animation at the same time. This made the whole thing look very rigid.  The bubbles were also lacking a pressure sensor. Though testing proved it wasn't mandatory to have one since the airpumps couldn't burst the bubbles. Pressure sensing will be nice to have when programming the behavior of the robots though.+The festival bubbles have some unresolved challenges.

Though testing proved it wasn't mandatory to have one since the airpumps couldn't burst the bubbles. A soft roboticist might also call this unintentional compliant design, but I am not scared of admitting my shortcomings. Most of all pressure sensing will be nice to have when programming the behavior of the robots.
  
 When I heard the announcement of the raspberry pi Pico, I got pretty excited about the PIO functionality. PIO seems to be perfect to control both neopixels and airflow, while still being able make decisions with the main loop. So a great prospect for soft robotics control. Thus I decided to reincarnate the festival bubbles into a desktop bubble, a portable soft bubble for code testing, prototyping and showing of soft robotics. When I heard the announcement of the raspberry pi Pico, I got pretty excited about the PIO functionality.
