Have you observed another hacker’s project and said to yourself, “I must have one!”? If so, you get on well with hacker [garberpark], an unusual chain clock manufacturer, as shown in the figure below.
When walking through the Chicago Avenue fire Art Center in Minneapolis, Minnesota, [garberpark] was stunned by the clock on the right here. In the clock, two motors drive a chain connected with numbers respectively, and the number on the top shows the current time. Not long after, garberpark found that it lacked such a clock. So they did what any hacker would do: they made their own version!
They used esp8266, Arduino and other basic electronic devices to horizontally interpret the clock they saw. Unlike continuous rotation, the limit switch keeps things consistent, while the NTP of esp8266 keeps things in time. The recycled scanner stepper motor provides movement, and things that look like bicycle cranks and chains work in coordination with the cut-off license plate to display the current time – but only if someone is around to observe; It feels very good and pays great attention to details!
If you like this, you will like the sprocket and chain clock we launched a few months ago.
