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 […]

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 […]

It’s been a month since my last post about my Arduino music player and remote.  This is a music system geared towards performers, like magicians, ventriloquists, jugglers and the like who perform a one man/woman show and need an easy way to queue up and play music and sounds. It uses two packet radio Arduino devices, […]

Yes, there are plenty of bluetooth enabled speakers that can be used with a smartphone to play music remotely, however, I was looking for a music system geared towards performers, like magicians, ventriloquists, jugglers and the like who perform a one man/woman show and need an easy way to queue up and play music and […]
