This is the third in a series of articles about using microcontroller devices with e-paper displays for displaying dynamic calendars. The custom Featherwing described in this article is available for purchase on Tindie. I wanted to create a few projects interfacing an e-paper display with the Adafruit HUZZAH 8266 and HUZZAH 32. The HUZZAH microcontrollers […]

This is the second in a series of articles about using microcontroller devices with e-paper displays for displaying dynamic calendars. A year ago a concept video was created by Japanese designer Kosho Tsuboi about a device called a magic calendar, which is an e-paper device that displays an events calendar and will automatically update when an […]

This is the first in a series of articles about using microcontroller devices with e-paper displays for displaying dynamic calendars. Standards can be a wonderful thing. At their best, they let computer hardware and software inter-operate between multiple vendors. Take calendar standards, for example. With the iCalendar standard, you can send a meeting invite from […]

When I started this blog two years ago, my first article described a hot potato game I wrote using the original Circuit Playground (before there was a Circuit Playground Express version). Now two years later I have created another game, the “Magic Hallowing”. Inspired by the children’s toy “Magic 8-Ball”, this Arduino sketch turns an Adafruit Hallowing […]

I found the personal compass project at Instructables.com quite interesting. Basically, a personal compass works like a regular compass, but instead of pointing to magnetic north, it points to a particular location of personal interest. Maybe it is pointing to the place where you were married, perhaps where your childhood home is. All this compass […]
