We’re so used to having an everything device in our pocket that we can experience a feeling of freedom when using an old a flip phone without a web browser, Netflix, or Genshin Impact. And now folks walk around with watches that are just as smart. But what if you want to make a dumb watch? Here’s a dumbwatch project from Maso via Hackaday:
This ATtiny85 based timepiece is an exercise in making the most minimally viable (not accurate) timepiece possible. Building on the I2C OLED/MCU combo of the previous version, this upgrade makes the important distinction of being functionally wearable with minimal fuss.
In it’s current form, the watch time is manually set with a single tactile button located just below the display.
This watch is built with the intention of being a base to iterate new revisions as easily as possible. Hence, the OLED and ATtiny are socketed making it easy to flash new firmware and possibly swap out displays.
