Tom Schofield created an installation artwork which visualises the ‘Doomsday Clock’, a symbolic clock maintained by an academic journal, ‘The Bulletin of Atomic Scientists’ which:

conveys how close humanity is to catastrophic destruction–the figurative midnight–and monitors the means humankind could use to obliterate itself. First and foremost, these include nuclear weapons, but they also encompass climate-changing technologies and new developments in the life sciences that could inflict irrevocable harm.

The artwork is composed by two pieces:

• a small computer programme running on a server which ‘scrapes’ the content of the bulletins home page as often as possible. The software checks the current status of the clock and then sends the results over the internet
• a small wall clock which receives data and displays the time of the Doomsday Clock on a red LED clock display. This process repeats as fast possible so that the device shows in near-real-time the status of the doomsday clock. 

The project uses an Arduino Uno board and an Arduino Ethernet shield and the clock is controlled with a MAX7219 Led control chip. Tom published  all the code and design for the indicator in his Github code repo  and told us he’s  very interested in the possibility that other people might make their own indicators. So, don’t be shy and give it a try!
