several visualizations of real-time coffee consumption tracked by hacking a real (& online) coffee machine. the arcs graph shows the average time caffeine remains in the body. the circles applet represents individual days as unique circles. circles are positioned based on the time coffee was taken, while color saturation & size convey the quantity of coffee.

an open, online API, allows anyone to create alternative visualizations of the coffee usage dataset.

We had a bit of fun with the same subject last year: https://formation.wallst.com/articles/2007/coffee_love

After seeing this originally on FlowingData, I looked at the source code (thanks for supplying it!) and found that the arcs are really just art. The starting point of the arc is the only real information here -- the arc size and length is random. I contacted the authors and they said this is because they wanted an impression of the lifetime of caffeine in the body, and this is dependent on many factors that they don't have access to. Just thought I'd clarify that there is less data here than it seems. But, it's an interesting idea!

It's good to see a common physical/static object becoming a generator of valuable information, just after a "simple" hack. This coffee machine is a source of free information, open for artists, scientists, or anyone else to play with. Great job!

ok, cool art ... but pretty useless otherwise because of many design flaws. also if one takes the data from several months it will totally fail to illustrate anything.

Hi @christopher, good to see you here. :)

The use of rfid tags (associated to openId [ http://openid.net/ ] ) to identify the consumer of
coffee is in our plans, after this, we will have more information.

@daniel, thanks... really, open and real data coffee machine! :P

useless? maybe, but it´s just fun. :P
