Doodle clock-robot using arduino

Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that’s been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it — a number beyond what he just erased.

More of Ekaggrat’s work can be found here.

Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that's been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it -- a number beyond what he just erased, of course. Per usual, these things are better seen than read about, so why not hop on past the break and mash play? Smiles await.

Wise Clock 4 Dual screen chronometer

This chronometer, inspired by the Doomsday clock by Wyolum, is made with a Wise Clock 4 board (available for sale here) and two 3216 displays from Sure Electronics.



Its main feature is the odometer-style rolling of the digits when they change.
The time is updated once a second, based on the 1Hz interrupt signal from DS3231, as described here.



















As shown in the video, one button is used to change the display brightness, another button is used for changing the font, and the third is used for switching between rolling style and static style.

By using the bigger (5mm) 3216 displays with the same setup and software, this clock can be easily read from a distance of at least 100 feet (30 meters).

Source code is available here. The current version does not allow setting up the time and date from buttons.

Dual screen Wise Clock 4

Using two 3216 displays together is an almost trivial hack. I wanted to make sure it works fine with the Wise Clock 4 board. The video below shows the new board running both "Night and Day" and "Wise Clock 3" (merged into one sketch, of course).




In practice, one can now build the "Dual Screen Wise Clock 4" with the two displays placed on opposite sides (back to back), or one next to the other (as shown in the video). A crazy idea would be to have 4 displays placed in a square :)
