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 […]

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.

I created this digital version of the hot potato game using simply a Circuit Playground board from Adafruit and a lipo battery.  The code is in Adafruit’s github repository as a pull request at the moment. The program utilizes the accelerometer in the board to determine when the board is being thrown and caught, and […]
