Here is one of his instrument experiments, exploring panpipes. See the photo at bottom for the earlier experiment that got him started — Wienermobile Panpipes by Ranjit:
After I added the tapered mouthpiece to the whistles, and with the hotdog-red ABS, these things remind me of a toy wienermobile I used to have. Thus the name.
This panflute is slightly more practical than the one it’s derived from. The curved shape is easier to use than the circle, and I added a bit of taper to the mouthpiece to make it easier to blow on a single whistle. Still not a practical musical instrument, though!
This one has a diatonic scale (CDEFGABC) instead of chromatic like the other one. I had to learn the OpenSCAD lookup() function for that!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
