I finally received a reward for a crowd-funded project, which arrived on December 31st.
Papier Machine Vol.0 is the first interactive electronic paper toy that unveils the mysteries of electronic black boxes.
I first heard about the project in July of 2017 and I made a super early bird pledge in January of 2018. The original estimated delivery for my reward was July of 2018, so it was about 5 months late. Not bad considering in that July 2017 post I had just backed a 3D printer on Kickstarter that is over a year late with no updated delivery timeline.
My nieces were down this weekend, so Kennedy and I made the first project.
This piano was an easy one. You use the varying amounts of graphite from a pencil to make a connection as you can see from the filled in areas around each of the keys. On the back side you connect a small circuit board with an integrated chip, a coin cell battery, and a piezo buzzer.
