This is a great story from start to finish that starts with the finished project and then goes back to the beginning and through the entire learning, adjusting, and modifying-along-the-way process, including quirks, bugs, and “aha!” moments. I especially dig the evolving ‘checklist’ of features and steps necessary for completion – that’s a pretty interesting admission in addition to the straight build notes, 3D .stl files, and code.

(Kind of makes me think of a doorbell you might in a movie like Fifth Element.)
One of my daughters lives in a college house with a bunch of students. The address has the number “5050” in it.

OLED Breakout Board – 16-bit Color 1.5″ w/microSD holder: We love our black and white monochrome displays but we also like to dabble with some color now and then. Our big 1.5″ color OLED displays are perfect when you need a small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 1.5″ diagonal and contains 128×128 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). We picked this display for its excellent color, this is the nicest mini OLED we could find! Read more.
