 +Kado Letters en naambordje.

 +Geleerd:
 +Linux Verdana is anders dan windows Verdana dus als je de 3D print en de lasercutter infill op andere computers genereerd met dezelfde OpenSCAD code dan past het toch niet.
 +
 +Gespiegeld laseren zorgt ervoor dat de rand die de onderkant wordt ligt naar binnen trekt. Omdat de onderkant van de letter dan op de bovenkant van de te laseren acryl plaat ligt.
 +
 +Met de juiste letters heb je geen extra tolerances nodig voor de oranje vulling.

 In the summer of 2019 I found myself with a bit of time on my hands. So a great opportunity to do some experiments with soft robotics. The first step was ordering a lot of silicone. This isn't cheap, however 1kg of type shore 8A (very flexible) will go a long way and it is super multi purpose. luckily [[https://softroboticstoolkit.com/low-cost-ep-circuit|the other things]] like DC-airpumps, solenoid valves, some kind of h-bridge and a micro-controller were reasonably priced, i.e. cheap. In the summer of 2019 I found myself with a bit of time on my hands.

-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.

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. 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.

 The next milestone will be adding the pressure sensor and making it battery powered. My main goal is to turn the Desktop Bubble into a learn guide and the electronics into a feather wing. Hopefully this will make starting out easier and also encourage more people to give soft robotics a try. It would be nice to see more hobby level projects using these techniques.So if you see something cool let me know! The next milestone will be adding the pressure sensor and making it battery powered.
