There are only four components: an Arduino Nano, a DS3231 RTC module, a SSD1306 128×64 OLED module, and a momentary pushbutton.

This is all accomplished with a 4×4 neopixel matrix, run by an Attiny85 Digispark with a DS3231 RTC module keeping time. A slight simplification is required to reduce the glyphs to 4×4, but we ...

Through the use of the Espressif Systems32(ESP32) microcontroller's embedded Global Positioning System (GPS) Neo 6m module, DS3231 RTC, Network time protocol(NTP) Pool Server, and Organic light ...

The Piccolo N150 is a tiny eight-inch laptop with more power than it suggests and a nice display. But as a writer, I've found it to be great for capturing ideas on the go.
